CALCULATION OF REGISTRATION FEE


Title of each class of securities to be registered	Amount to be registered(1)	Proposed maximum offering price per unit	Proposed maximum aggregate offering price(2)	Amount of registration fee(3)

Common stock, par value $0.01 per share	269,678,387	Not Applicable	$17,022,570,965	$1,821,415

(1): The number of shares of common stock, par value $0.01 per share, of the registrant ("NYSE Euronext common stock") being registered is based upon the sum of (i) the product obtained by multiplying (x) 159,212,135 shares of common stock, par value $0.01 per share, of NYSE Group, Inc. ("NYSE Group common stock") estimated that will be outstanding, on a fully diluted basis, immediately prior to the merger by (y) an exchange ratio of 1.0, plus (ii) the product obtained by multiplying (a) 112,720,665 ordinary shares, par value €6 per share, of Euronext N.V. estimated that will be outstanding, on a fully diluted basis, immediately prior to the completion of the exchange offer, by (b) an exchange ratio of 0.98.
(2): Pursuant to Rule 457(c) and Rule 457(f), and solely for the purpose of calculating the registration fee, the market value of the securities to be offered was calculated as the sum of (a) the product of (i) 159,212,135 shares of NYSE Group common stock, par value $0.01 per share, estimated that will be outstanding on a fully-diluted basis, immediately prior to the merger, and (ii) the average of the high and low sales prices of NYSE Group common stock on September 14, 2006 and (b) the product of (i) 112,720,665 Euronext ordinary shares estimated to be outstanding multiplied by .98 and (ii) the average of the high and low sales prices of Euronext shares on September 14, 2006 (converted into U.S. Dollars on the basis of an exchange rate of 1 euro =$1.2736, which was the Federal Reserve Bank of New York noon buying rate on that date) less $3,060,721,350, the estimated maximum aggregate amount of cash to be paid by NYSE Euronext in the offer and post-closing reorganization in exchange for such securities.
(3): Calculated by multiplying the estimated aggregate offering price of securities to be registered by 0.000107.

The Registrant hereby amends this Registration Statement on such date or dates as may be necessary to delay its effective date until the Registrant shall file a further amendment which specifically states that this Registration Statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933 or until this Registration Statement shall become effective on such date as the Commission, acting pursuant to said Section 8(a), may determine.

•: a prospectus that will be used as a shareholder circular in connection with the Euronext extraordinary meeting of shareholders being held to approve the combination agreement and the transactions contemplated by the combination agreement, including the post-closing reorganization (the "Shareholder Circular/Prospectus"); and

•: the table of contents, as well as the page numbers, of each document will be different as a result of the differences outlined above.

SUBJECT TO COMPLETION, DATED [ • ], 2006

PROXY STATEMENT OF NYSE GROUP, INC.

PROSPECTUS OF NYSE EURONEXT, INC.

To the Stockholders of NYSE Group, Inc.:

NYSE Group and Euronext N.V. have entered into an agreement providing for a combination of their businesses under a new holding company named NYSE Euronext. Euronext's business will be brought under the new holding company through an exchange offer, and NYSE Group's business will be brought under the new holding company through a merger (which, together with the exchange offer, is referred to in this document as the "combination"). The combination will create the first global exchange company and the world's largest securities marketplace, encompassing seven exchanges in six countries.

The merger will occur immediately after the successful completion of the exchange offer. In the merger, NYSE Group stockholders will have the right to receive one share of NYSE Euronext common stock for each of their shares of NYSE Group common stock. Shares of NYSE Euronext common stock that are issued to NYSE Group stockholders in the merger will be subject to the same transfer restrictions, if any, that the shares of NYSE Group common stock were subject to prior to the merger.

Simultaneously with or as soon as possible after the merger, NYSE Euronext plans to effectuate a post-closing reorganization that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer.

Based on the current number of outstanding shares of NYSE Group common stock and Euronext shares, NYSE Euronext will issue approximately 269.7 million shares of NYSE Euronext common stock in the combination. NYSE Euronext intends to apply to list the NYSE Euronext common stock on the New York Stock Exchange (or the "NYSE") under the symbol "[ • ]," and on Euronext Paris (Eurolist by Euronext) under the symbol "[ • ]," (ISIN Code [ • ]) subject to official notice of issuance of the stock in the combination. NYSE Group common stock, which is listed on the NYSE under the symbol "NYX," will be delisted after the merger is completed.

The combination agreement requires that the combination be approved by the NYSE Group stockholders and Euronext shareholders. To obtain these approvals, NYSE Group will hold a special meeting of its stockholders on [ • ], 2006, at which it will ask its stockholders to approve and adopt the combination agreement and the transactions contemplated thereby (and consider any other matters properly brought before the meeting). After the requisite shareholder approvals have been obtained, NYSE Euronext will file the exchange offer with the French Autorité des Marchés Financiers ("AMF") and commence the exchange offer. Information about the NYSE Group special meeting, the combination and other business to be considered by NYSE Group stockholders is contained in this document, which we urge you to read. In particular, see "Risk Factors" beginning on page34.

Your vote is very important. Whether or not you plan to attend the NYSE Group special meeting, please take appropriate action to make sure your NYSE Group common stock is represented at the NYSE Group special meeting. Your failure to vote will have the same effect as voting against the approval and adoption of the combination agreement. The NYSE Group board of directors recommends that the NYSE Group stockholders vote FOR the approval and adoption of the combination agreement.

QUESTIONS AND ANSWERS ABOUT PROCEDURES FOR THE NYSE GROUP
SPECIAL MEETING

The questions and answers below highlight only selected procedural information from this document. They do not contain all of the information that may be important to you. You should read carefully this entire document, including its annexes to fully understand the proposed transaction and the voting procedures for the NYSE Group special meeting.

Q:: What is the proposed transaction for which I am being asked to vote?
A:: NYSE Group stockholders are being asked to vote to approve and adopt the combination agreement between NYSE Group and Euronext. The combination agreement provides for a combination of the businesses of NYSE Group and Euronext under a new holding company named NYSE Euronext. Euronext's business will be brought under the new holding company through an exchange offer, and NYSE Group's business will be brought under the new holding company through a merger. The merger will occur as soon as practicable following the successful completion of the exchange offer.

Following the successful completion of the exchange offer and merger, NYSE Euronext intends to effectuate a corporate reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. Under the corporate reorganization, Euronext shareholders who did not exchange their Euronext shares in the exchange offer will be provided with the same consideration that such shareholders would have received had they tendered their Euronext shares in the exchange offer and not made the cash election or the stock election (each as described below). Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext share-
holders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer. This document refers to this corporate reorganization as the "post-closing reorganization."

The NYSE Group board of directors recommends that the NYSE Group stockholders vote to approve and adopt the combination agreement and the transactions contemplated thereby. For a discussion of the reasons for this recommendation, see "The Combination—NYSE Group's Reasons for the Combination."

Q:: What will I receive in the combination if I am a NYSE Group stockholder?
A:: In the merger, NYSE Group stockholders will be entitled to receive one share of NYSE Euronext common stock for each of their shares of NYSE Group common stock. NYSE Group stockholders will not have the right to elect to alter this standard consideration.

Shares of NYSE Euronext common stock that are issued to NYSE Group stockholders in the merger will be subject to the same transfer restrictions, if any, that the shares of NYSE Group common stock were subject to prior to the merger.

Q:: What will happen to my stock options and my NYSE Group restricted stock units in the combination?
A:: In the combination, stock options to acquire NYSE Group common stock will be converted into options to acquire an equal number of shares of NYSE Euronext common stock, and NYSE Group restricted stock units will be converted into an equal number of NYSE Euronext restricted stock units.

Q:: What will Euronext shareholders receive in the combination?
A:: In the exchange offer, Euronext shareholders will have the right to exchange each of their Euronext shares for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. Instead of receiving this standard offer consideration, Euronext shareholders will have an opportunity to make either a cash election to receive all cash for their Euronext shares, or a stock election to receive all stock for their Euronext shares. The precise amount of cash payable in respect of a cash election, and the precise number of shares of NYSE Euronext common stock issuable in respect of a stock election will be determined prior to the filing of the exchange offer with the French Autorité des Marchés Financiers (the "AMF") and will depend on the volume weighted average price of NYSE Group common stock during the 10 consecutive trading days ending immediately prior to the date of the filing of the exchange offer with the AMF. In addition, both the cash election and stock election are subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all tendering Euronext shareholders received the standard offer consideration. Euronext shareholders who make no election will receive the standard offer consideration.

If a holder of exercisable options to acquire Euronext shares would like to tender the underlying Euronext shares into the exchange offer, such holder must first exercise the options and then tender the underlying Euronext shares on or prior to the expiration date of the exchange offer or the subsequent offering period, if applicable.

Q:: What will happen to Euronext shares that are not tendered in the exchange offer?
A:: As soon as possible after the successful completion of the exchange offer and the merger, NYSE Euronext intends to effectuate a post-closing reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. In the post-closing reorganization, Euronext shareholders who did not exchange their Euronext shares in the exchange offer will generally receive the same consideration that they would have received had they tendered their Euronext shares in the exchange offer and not made either the cash election or the stock election; that is, €21.32 in cash and 0.98 of a share of NYSE Euronext common stock per Euronext share. Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext share-
holders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer.

In the event that 95% or more of the issued and outstanding share capital of Euronext is tendered in the exchange offer or any subsequent offering period, NYSE Euronext may at its option effectuate the post-closing reorganization by initiating a compulsory acquisition procedure (uitkoopregeling) in accordance with article 2:92a of the Dutch Civil Code. In such circumstances, the price to be paid for such shares would be paid in cash only, in an amount determined at the time by the Enterprise Chamber of the Amsterdam Court of Appeals, which may be in an amount that is substantially more or less than the value of the consideration that Euronext shareholders would have received had they tendered their Euronext shares in the exchange offer.

The post-closing reorganization is intended to eliminate any minority stockholder interest in Euronext remaining after the completion of the exchange offer.

Q:: What will happen to Euronext options and Euronext stock-based awards following the exchange offer?

If the exchange offer is consummated, any remaining Euronext stock options or other Euronext stock-based awards, whether vested or unvested, will be converted into a NYSE Euronext stock option or a NYSE Euronext stock-based award, respectively, on the same terms and conditions as were applicable under such Euronext stock option and Euronext stock-based award prior to the post-closing reorganization.

The number of shares of NYSE Euronext common stock underlying each such NYSE Euronext stock option or NYSE Euronext stock-based award shall be the number of Euronext shares underlying each such Euronext stock option or Euronext stock-based award multiplied by the stock election amount (which is the number of shares of NYSE Euronext common stock that a Euronext shareholder who made the stock election in the offer would have received in the exchange offer, assuming no proration or other adjustments), rounded, if necessary, to the nearest whole share of NYSE Euronext common stock. These NYSE Euronext stock options will have an exercise price per share (rounded to the nearest one-hundredth of a cent) equal to the per share exercise price of the applicable Euronext stock option divided by the stock election amount.

In certain circumstances, if the conversion of any Euronext stock options and Euronext stock-based awards into NYSE Euronext stock options and NYSE Euronext stock-based awards would cause holders who are French residents for tax purposes to incur incrementally more taxes and/or social security charges than would be the case had they otherwise complied with certain requirements for favorable tax treatment under French law (including by holding the Euronext stock options and Euronext stock-based awards for requisite holding and vesting periods), NYSE Euronext intends to make specific arrangements for such holders in order to avoid, or reimburse them for, such incremental tax and social security liability. For a description of these arrangements, see "The Combination Agreement—Treatment of Euronext Stock Options and Stock-Based Awards Following the Exchange Offer."

Q:: Will the NYSE Euronext common stock issued in the merger or exchange offer be subject to transfer restrictions?
A:: The shares of NYSE Euronext common stock issued to NYSE Group stockholders in the merger will be subject to the same transfer restrictions, if any, to which their shares of NYSE Group common stock were subject prior to the merger.
: The shares of NYSE Euronext common stock issued to Euronext shareholders in the exchange offer will NOT be subject to transfer restrictions.
Q:: How do I vote if I am a NYSE Group stockholder?
A:: NYSE Group stockholders can vote by telephone, through the Internet or by returning their signed and dated proxy card by mail. Alternatively, they may vote in person at the NYSE Group special meeting by ballot.

If a NYSE Group stockholder holds NYSE Group common stock in its own name, it may vote by telephone or through the Internet by following the instructions on the accompanying proxy card. If the NYSE Group common stock is registered in the name of a broker, bank or other nominee (which is also known as being held in "street name"), that broker, bank or other nominee has enclosed or will provide a voting instruction card for the NYSE Group stockholder to direct the broker, bank or other nominee how to vote its shares.

NYSE Group stockholders who hold shares in "street name" must return their

instructions to their broker, bank or other nominee on how to vote their shares. If a NYSE Group stockholder that holds shares in "street name" desires to attend the NYSE Group special meeting, the NYSE Group stockholder should bring a letter from its broker, bank or other nominee identifying the NYSE Group stockholder as the beneficial owner of such shares and authorizing the NYSE Group stockholder to vote.

You should be aware that, as of [ • ], 2006, NYSE Group directors and executive officers and their affiliates owned and were entitled to vote approximately [ • ]% of the outstanding shares of NYSE Group common stock entitled to vote at the NYSE Group special meeting.

The NYSE Group certificate of incorporation and bylaws contain certain voting limitations for NYSE Group stockholders. A description of these voting limitations is set forth under "The Special Meeting of NYSE Group Stockholders—Voting Limitations."

Q:: If I am a NYSE Group stockholder and my shares of NYSE Group common stock are held in "street name" by a broker, bank or other nominee, will my broker or bank vote my shares for me?
A:: If you hold your shares of NYSE Group common stock in "street name" and do not provide voting instructions to your broker, your NYSE Group common stock will not be voted on any proposal on which your broker does not have discretionary authority to vote. Generally, your broker, bank or other nominee does not have discretionary authority to vote on the combination agreement. Accordingly, your broker, bank or other nominee will vote your shares held by it in "street name" only if you provide voting instructions. You should follow the procedures that your broker, bank or other nominee provides. Shares that are not voted because you do not properly instruct your broker, bank or other nominee will have the effect of votes against the adoption of the combination agreement.

Alternatively, you can attend the NYSE Group special meeting and vote in person by bringing a letter from your broker, bank or other nominee identifying you as the beneficial owner of such shares of NYSE Group common stock, confirming that such shares have not otherwise been voted and will not be voted via proxy, and authorizing you to vote the shares or specifying how such shares had been voted.

Q:

If I am a NYSE Group stockholder, what happens if I do not vote or if I abstain from voting?

A:

Approval and adoption of the combination agreement by the NYSE Group stockholders requires the affirmative vote of a majority of the shares of NYSE Group common stock outstanding and entitled to vote at the NYSE Group special meeting. As a result, if you are a NYSE Group stockholder and do not vote or abstain from voting your shares of NYSE Group common stock, this will have the same effect as voting against the approval and adoption of the combination agreement. Likewise, broker non-votes and abstentions will have the same effect as a vote against the proposal to approve and adopt the combination agreement.

Q:

Can I change my vote after I have delivered my proxy?

A:

Yes. If you are a NYSE Group stockholder of record, there are three ways to change your vote after you have submitted a proxy:

•: you may send a later-dated, signed proxy card to the address indicated on the proxy card, which must be received prior to the applicable special meeting;
•: you may attend the applicable special meeting in person and vote; or
•: you may send a notice of revocation to the agent for NYSE Group, as applicable, which notice must be received prior to the applicable special meeting.

Simply attending the special meeting without voting will not revoke your proxy. NYSE

Group proxy cards can be sent by mail to [ • ].

If your shares of NYSE Group common stock are held in an account at a broker, bank or other nominee and you have instructed your broker, bank or other nominee on how to vote your shares, you should follow the instructions provided by your broker, bank or other nominee to change your vote.

Q:: Should I send any document representing my NYSE Group common stock at this time?
A:: No. Please DO NOT send any document representing your NYSE Group common stock at this time.

Upon completion of the merger, NYSE Euronext will mail a letter of transmittal to NYSE Group stockholders of record as of immediately prior to the merger. In order to receive the merger consideration, NYSE Group stockholders will be required to complete and submit the letter of transmittal along with any required documentation pursuant to the instructions set forth in the letter of transmittal.

Q:: When and where is the NYSE Group special meeting?
A:: The NYSE Group special meeting will take place on [ • ] at [location] at [ • ], Eastern Time.
Q:: Who can help answer my questions?
A:: If you have any questions about the combination, the post-closing reorganization or how to submit your proxy, or if you need additional copies of this document, the form of election or the enclosed proxy card, you should contact:

The Companies

NYSE Group, Inc. (see page 203)

NYSE Group, Inc., a Delaware corporation, is a holding company that, through its subsidiaries, operates two securities exchanges: the New York Stock Exchange LLC (or the "NYSE") and NYSE Arca, Inc. NYSE Group is a leading provider of securities listing, trading and market data products and services. NYSE Group was formed in connection with the merger of the NYSE and Archipelago, which was completed on March 7, 2006. Although the trading platforms of the NYSE and NYSE Arca currently operate separately, NYSE Group is actively integrating certain of their activities to achieve revenue and cost synergies.

The NYSE is the world's largest cash equities exchange. The NYSE is approximately three times the size of the next largest cash equities exchange in the world in terms of total worldwide market capitalization of listed companies. The NYSE provides a reliable, orderly, liquid and efficient marketplace where investors buy and sell listed issuers' common stock and other securities. For 214 years, the NYSE has facilitated capital formation, serving a wide spectrum of participants, including individual and institutional investors, the trading community and listed companies. As of June 30, 2006, 2,697 issuers, which include domestic and non-domestic operating companies, closed-end funds and exchange traded funds ("ETFs"), were listed on the NYSE. The NYSE's listed operating companies represent a total worldwide market capitalization of over $22.6 trillion, as of June 30, 2006. For the period from January 1, 2006 to June 30, 2006, on an average trading day, over 1.77 billion shares, valued at over $67.0 billion, were traded on the NYSE.

NYSE Arca operates the first open, all-electronic stock exchange in the United States and has one of the leading market positions in trading ETFs and exchange listed securities. NYSE Arca is also an exchange for trading equity options. Through NYSE Arca, customers can trade over 8,000 equity securities and over 145,000 options series. NYSE Arca's equity trading platforms link traders to multiple U.S. market centers and provide customers with fast electronic execution and open, direct and anonymous market access. The technological capabilities of NYSE Arca's trading platforms, combined with its trading rules, have allowed NYSE Arca to create a large pool of liquidity that is available to customers internally on NYSE Arca and externally through other market centers. For the period from January 1, 2006 to June 30, 2006, on an average trading day, over 795.1 million shares, valued at over $27.4 billion, were traded through NYSE Arca's trading platforms.

For the six months ended June 30, 2006, on a pro forma basis reflecting the merger of the NYSE and Archipelago, based on financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"), NYSE Group generated $898.6 million in revenues (excluding activity assessment fees) and $126.9 million in income from continuing operations.

NYSE Group Special Meeting (see page 63)

The special meeting of NYSE Group stockholders will be held at [ • ], on [ • ], starting at [ • ], local time. You are entitled to notice of, and to vote at, the NYSE Group special meeting if you owned NYSE Group common stock at the close of business on [ • ], the record date. As of [ • ], there were [ • ] shares of NYSE Group common stock issued and outstanding, of which [ • ] shares were entitled to vote at the NYSE Group special meeting after taking into account the voting limitations described below.

Each share of NYSE Group common stock is entitled to one vote on each proposal at the NYSE Group special meeting, subject to the voting limitations described below. The affirmative vote of the holders of a majority of the shares of NYSE Group common stock outstanding and entitled to vote at the NYSE Group special meeting as of the record date is required for the approval and adoption of the combination agreement and each other proposal presented at the NYSE Group special meeting. The holders of record of a majority of the total number of outstanding shares of NYSE Group common stock entitled to vote, represented either in person or by proxy, will constitute a quorum at the NYSE Group special meeting.

What Tendering Euronext Shareholders Will Receive in the Exchange Offer (see page 129)

In the exchange offer, which will be filed with, reviewed by and subject to the approval of the AMF after the satisfaction or waiver of the conditions in the combination agreement (including the approval of NYSE Group stockholders and Euronext shareholders of the combination), NYSE Euronext or a wholly owned subsidiary will offer to acquire each outstanding Euronext share for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. This document refers to this mix of consideration as the "standard offer consideration."

Instead of receiving this standard offer consideration, Euronext shareholders who tender their shares in the exchange offer will have an opportunity to make either a cash election to receive all cash for their Euronext shares, or a stock election to receive all stock for their Euronext shares. The precise amount of cash payable in respect of a cash election, and the precise number of NYSE Euronext shares issuable in respect of a stock election will be determined prior to the filing of the exchange offer with the AMF and will depend on the volume weighted average price of NYSE Group common stock during the 10 consecutive trading days ending immediately prior to the date of the filing of the exchange offer. In addition, both the cash election and stock election are subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all tendering Euronext shareholders received the standard offer consideration. Euronext shareholders who make no election will receive the standard offer consideration.

As a result, if the cash election or the stock election is oversubscribed, Euronext shareholders making the oversubscribed election will receive both cash and shares of NYSE Euronext common stock, in proportion to the relative amounts available of each. As the cash election or stock election becomes more oversubscribed, Euronext shareholders making the oversubscribed election will receive consideration that will more closely resemble the standard offer consideration. Euronext shareholders who tender their shares in the exchange offer and make no election will receive the standard offer consideration. The precise consideration that Euronext shareholders will receive if they make the cash election or the stock election will depend on both:

•: the volume weighted average price of NYSE Group common stock during the 10 consecutive trading days ending immediately prior to the date of the filing of the exchange offer with the AMF; and
•: the number of Euronext shareholders that make the cash election and the number that make the stock election.

This information (and therefore the precise consideration that Euronext shareholders will receive if they make the cash election or the stock election) will not be available at the time that Euronext shareholders vote on the combination. The combination agreement contains no provision that permits either party to terminate the combination agreement, or that alters the exchange ratio, because the stock price of NYSE Group common stock or Euronext shares has fallen below any agreed-upon minimum price or has risen above an agreed-upon maximum price. For a more detailed description of the potential adjustments to the consideration that Euronext shareholders will receive if they make the cash election or the stock election, see "The Combination Agreement—The Exchange Offer—Consideration Offered to Euronext Shareholders" and "The Combination Agreement—The Exchange Offer—Mix and Match Election."

If a person holds exercisable options to acquire Euronext shares and would like to tender the underlying Euronext shares into the exchange offer, such person must first exercise the options and then tender the underlying Euronext shares on or prior to the expiration date of the exchange offer or the subsequent offering period.

shareholders will equal approximately 41% of the NYSE Euronext common stock issued and outstanding at the time of completion of the combination.

NYSE Euronext is not obligated to purchase any tendered Euronext shares unless the tendered Euronext shares represent at least two-thirds of the total outstanding shares of Euronext. After consultation with Euronext, however, NYSE Euronext may lower this two-thirds minimum condition to a number representing not less than a majority of the Euronext voting power on a fully diluted basis taking into account all Euronext shares issuable upon the exercise of any options, warrants or rights to purchase or subscribe for shares of the capital stock of Euronext.

What NYSE Group Stockholders and Holders of NYSE Group Stock Options and Restricted Stock Units Will Receive in the Merger (see page 132)

In the merger, pursuant to the combination agreement, each share of NYSE Group common stock will entitle its holder to one share of NYSE Euronext common stock. Shares of NYSE Euronext common stock that are issued to NYSE Group stockholders in the merger will be subject to the same transfer restrictions, if any, that the shares of NYSE Group common stock were subject to prior to the merger. In addition, holders of outstanding NYSE Group stock options to acquire shares of NYSE Group common stock will receive options to acquire an equal number of shares of NYSE Euronext common stock, and holders of outstanding restricted stock units of NYSE Group common stock will receive an equal number of restricted stock units of NYSE Euronext common stock.

Assuming that all of the outstanding Euronext shares are validly tendered in the exchange offer and not withdrawn, the aggregate number of shares of NYSE Euronext common stock issued in the combination to the NYSE Group stockholders will equal approximately 59% of the NYSE Euronext common stock issued and outstanding at the time of completion of the combination.

What Euronext Shareholders Will Receive if They Do Not Tender Their Euronext Shares in the Exchange Offer (see page [ • ])

If the exchange offer is consummated, NYSE Euronext intends to effectuate a post-closing reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. In the post-closing reorganization, Euronext shareholders who did not tender their Euronext shares in the exchange offer will generally be provided with the same consideration that they would have received had they tendered their Euronext shares in the exchange offer and had they not made either the cash election or stock election for their Euronext shares, that is, €21.32 in cash and 0.98 of a share of NYSE Euronext common stock per Euronext share. Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer.

In the event that 95% or more of the issued and outstanding share capital of Euronext is tendered and accepted in the exchange offer, NYSE Euronext may at its option effectuate the post-closing reorganization by initiating a compulsory acquisition procedure (uitkoopregeling) in accordance with section 2:92a of the Dutch Civil Code. In such circumstances, the price to be paid for such shares would be paid in cash only, in an amount determined by the Enterprise Chamber of the Amsterdam Court of Appeals, which amount may be substantially more or less than the value of the consideration that Euronext shareholders received in the exchange offer.

If successful, the effect of the post-closing reorganization will be to eliminate any minority stockholder interest in Euronext remaining after the completion of the exchange offer. For further details regarding the post-closing reorganization, see "The Combination Agreement—Post-Closing Reorganization."

How Holders of Euronext Options and Stock-Based Awards Can Participate in the Exchange Offer (see page 132)

Holders of exercisable Euronext stock options who would like to tender the underlying Euronext shares into the exchange offer must first exercise such stock options (to the extent such stock options are exercisable) and then tender the underlying Euronext shares on or prior to the expiration date of the exchange offer. Holders of Euronext stock-based awards will not be entitled to tender the underlying Euronext shares in the exchange offer. For further details regarding the procedure for participating in the exchange offer, see "The Combination Agreement—Treatment of Euronext Stock Purchase Options and Euronext Stock-Based Awards".

What Holders of Euronext Options and Stock-Based Awards Will Receive if They Do Not Exercise Their Options or Stock Based Awards and Tender the Shares in the Exchange Offer (see page 133)

If, following the successful completion of the exchange offer, there are still Euronext stock options and Euronext stock-based awards outstanding, a conversion mechanism will generally be implemented for purposes of converting such stock options and stock-based awards into NYSE Euronext stock options and NYSE Euronext stock-based awards, respectively, on the same terms and conditions as currently applicable, subject to specific arrangements being made available to certain holders in order to protect such holders' tax and social security treatment. For a description of the conversion mechanism and these arrangements, please see "The Combination Agreement—Treatment of Euronext Stock Options and Stock-Based Awards Following the Exchange Offer."

Structure of the Combination (see page 129)

In the combination, Euronext's business will be brought under NYSE Euronext through the exchange offer, and NYSE Group's business will be brought under NYSE Euronext through the merger. As soon as possible after the successful completion of the exchange offer and the merger, NYSE Euronext intends to effectuate the post-closing reorganization.

The following diagram illustrates the structure of the combination and assumes full completion of the post-closing reorganization so that 100% of the equity of Euronext is held by NYSE Euronext:

After the Combination and the Post-Closing Reorganization

For a more detailed diagram of NYSE Euronext after the combination, see "The Combination Agreement—Structure of the Combination."

Description of Credit Facility (see page 122)

In connection with the exchange offer, NYSE Euronext will enter into a credit facility agreement that will permit it to borrow amounts sufficient to fund the cash portion of the consideration to be issued in the exchange offer, which is expected to be $3.0 billion. NYSE Euronext may only borrow amounts under this credit facility agreement if the combination is successful. If the combination is successful, NYSE Euronext expects to use the credit facility as an undrawn back stop for a Global Commercial Paper Program, which NYSE Euronext will use mainly to finance the cash portion of the consideration to be paid to Euronext shareholders pursuant to the exchange offer. The credit facility will include terms and conditions customary for agreements of this type, which could restrict NYSE Euronext's ability to engage in additional transactions or incur additional indebtedness.

Reasons for the Combination (see page 75)

NYSE Group Stockholders. Based on NYSE Group's reasons for the combination described in this document (see "The Combination—NYSE Group's Reasons for the Combination"), the NYSE Group board of directors approved the combination agreement, which provides that the board will recommend, subject to fiduciary duties under applicable law, that the NYSE Group stockholders vote FOR the approval and adoption of the combination agreement and the transactions contemplated by the combination agreement.

Interests of Directors, Board Members, and Executive Officers in the Combination (see page 105)

You should be aware that some of the directors and executive officers of NYSE Group and managing and supervisory board members of Euronext may have interests in the combination that are different from, or in addition to, the interests of the NYSE Group stockholders and the Euronext shareholders. These interests may include, but are not limited to, the continued employment of certain executive officers of NYSE Group and managing board members of Euronext, the continued positions of certain directors of NYSE Group and supervisory board members of Euronext as directors of NYSE Euronext, and the indemnification of former directors and executive officers of NYSE Group and managing and supervisory board members of Euronext by NYSE Euronext. These interests also include the treatment in the combination of restricted stock units, stock options and other rights held by these directors, board members and executive officers.

Opinions of Financial Advisors (see page 88)

In connection with the proposed combination, the Euronext supervisory and managing boards retained Morgan Stanley & Co. Limited ("Morgan Stanley") and ABN AMRO Corporate Finance France S.A. ("ABN AMRO") to act as financial advisors and to deliver separate opinions in connection with the proposed combination. Morgan Stanley rendered to the Euronext supervisory and managing boards such an opinion, dated as of June 1, 2006, to the effect that, as of the date of the opinion and based upon and subject to the assumptions, and other limitations set forth in the opinion, the consideration to be received by the Euronext shareholders in the exchange offer was fair, from a financial point of view, to the Euronext shareholders, as a whole. ABN AMRO rendered to the Euronext supervisory and managing boards such an opinion, dated as of June 1, 2006, to the effect that, as of the date of the opinion and based upon and subject to the assumptions, qualifications and other considerations set forth therein, the standard consideration to be offered to the Euronext shareholders in the exchange

offer was fair, from a financial point of view, to the Euronext shareholders.

In connection with the proposed combination, the NYSE Group retained Citigroup Global Markets Inc. ("Citigroup") to act as a financial advisor and to deliver an opinion in connection with the proposed combination. Citigroup rendered to the NYSE Group board of directors an opinion, dated June 1, 2006, to the effect that, as of the date of the opinion and based upon and subject to the considerations and limitations set forth in the opinion, the aggregate consideration to be paid by NYSE Euronext in the exchange offer is fair, from a financial point of view, to NYSE Group.

The full text of the written opinions of Citigroup, Morgan Stanley and ABN AMRO are included as Annexes B, C and D, respectively, to this document and are incorporated into this document by reference. You are urged to read each of the opinions carefully and in their entirety for a description of the procedures followed, matters considered and limitations on the review undertaken.

Material Dutch Tax Consequences (see page 112)

See "The Combination—Material Dutch Tax Consequences" for a discussion of the Dutch tax consequences of the combination to Euronext shareholders. You are urged to consult with your tax advisor for a full understanding of the tax consequences of the combination to you.

Material U.S. Federal Income Tax Consequences (see page 117)

The Merger

The merger has been structured to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. It is a condition to the obligation of NYSE Euronext to file and commence the exchange offer that NYSE Group receive an opinion from its counsel to the effect that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. Assuming the merger qualifies as a reorganization, holders of NYSE Group common stock generally will not recognize any gain or loss for U.S. federal income tax purposes on the exchange of their NYSE Group common stock for NYSE Euronext common stock in the merger.

Holders of NYSE Group common stock should read "The Combination—Material U.S. Federal Income Tax Consequences—Tax Consequences of the Merger to U.S. Holders of NYSE Group Common Stock" for a more complete discussion of the U.S. federal income tax consequences of the merger. Holders of NYSE Group common stock should consult their own tax advisors to determine the tax consequences to them (including the application and effect of any state, local or non-U.S. income and other tax laws) of the merger.

The Exchange Offer and the Post-Closing Reorganization

The combination agreement contemplates that the receipt by holders of Euronext shares of the consideration in the exchange offer and in the post-closing reorganization will be structured as a taxable transaction for U.S. federal income tax purposes, unless NYSE Group elects, subject to the provisions of the combination agreement, to structure the post-closing reorganization so that, in the opinion of counsel to NYSE Group, the exchange offer together with the post-closing reorganization is treated either as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code or an exchange described in Section 351 of the Internal Revenue Code. As of the date of this document, NYSE Group has not made the election described in the preceding sentence. In addition, because the structure of the post-closing reorganization may depend, among other things, on the percentage of the Euronext shares tendered in the exchange offer, NYSE Euronext may not be able to determine the structure of the post-closing reorganization and whether to make the election described above until the expiration of the exchange offer. Holders of Euronext shares who are subject to U.S. federal income taxes should recognize and consider that the combination agreement contemplates that the receipt by holders of Euronext shares of the consideration in the exchange offer and in the post-closing reorganization will be structured as a

taxable transaction for U.S. federal income tax purposes.

Taxable Exchange. If, as currently contemplated by the combination agreement, the receipt by holders of Euronext shares of the consideration in the exchange offer or in the post-closing reorganization is treated as a taxable transaction for U.S. federal income tax purposes, a U.S. holder of Euronext shares generally will recognize gain or loss in an amount equal to the difference, if any, between (1) the amount realized, and (2) the holder's tax basis in the Euronext shares exchanged. The amount realized will be the fair market value of the NYSE Euronext common stock, if any, plus the amount of cash, if any, received pursuant to the exchange offer or the post-closing reorganization. In general, a non-U.S. holder of Euronext shares will not be subject to U.S. federal income tax in respect of the consideration received in the exchange offer or in the post-closing reorganization, unless such non-U.S. holder has certain connections to the United States.

Reorganization Within the Meaning of Section 368(a) of the Internal Revenue Code or Exchange described in Section 351 of the Internal Revenue Code. If NYSE Group elects to structure the exchange offer together with the post-closing reorganization as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code or as an exchange described in Section 351 of the Internal Revenue Code, and the post-closing reorganization together with the exchange offer so qualifies, the material U.S. federal income tax consequences to U.S. holders of Euronext shares, in general, are as follows:

•: If a U.S. holder receives solely NYSE Euronext common stock in exchange for its Euronext shares, such holder generally will not recognize any gain or loss, except with respect to cash received in lieu of fractional shares of NYSE Euronext common stock.
•: If a U.S. holder receives solely cash in exchange for its Euronext shares, such holder generally will recognize gain or loss equal to the difference between the amount of cash received and the tax basis in such holder's Euronext shares.
•: If a U.S. holder receives a combination of NYSE Euronext common stock and cash in exchange for its Euronext shares and such holder's tax basis in its Euronext shares is less than the sum of the cash and the fair market value, as of the closing date of the exchange offer or the post-closing reorganization, as applicable, of the NYSE Euronext common stock received, such holder generally will recognize gain equal to the lesser of (1) the sum of the cash and the fair market value of the NYSE Euronext common stock received, minus the tax basis of such holder's Euronext shares surrendered, and (2) the amount of cash received in the exchange offer or the post-closing reorganization as applicable. However, if a U.S. holder's tax basis in the Euronext shares exchanged in the exchange offer or the post-closing reorganization is greater than the sum of the cash and the fair market value of the NYSE Euronext common stock received, such holder's loss will not be currently allowed or recognized for U.S. federal income tax purposes.

In general, a non-U.S. holder of Euronext shares will not be subject to U.S. federal income tax in respect of the consideration received in the exchange offer or in the post-closing reorganization, unless such non-U.S. holder has certain connections to the United States.

All holders of Euronext shares should read "The Combination—Material U.S. Federal Income Tax Consequences—Tax Consequences of the Exchange Offer and the Post-Closing Reorganization to U.S. and Non-U.S. Holders of Euronext Shares" for a more complete discussion of the U.S. federal income tax consequences of the exchange offer and the post-closing reorganization. Holders of Euronext shares should consult their own tax advisors to determine the tax consequences to them (including the application and effect of any state, local or non-U.S. income and other tax laws) of the exchange offer and the post-closing reorganization.

Regulatory Approvals and Conditions to Completion of the Combination (see page 123)

Competition and Antitrust

NYSE Group and Euronext are not required to make notifications under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the rules promulgated under the HSR Act by the Federal Trade Commission (the "FTC"). Competition and regulatory notifications and approvals may be required from certain European authorities. In particular, competition consents will be required from the Office of Fair Trading in the United Kingdom, pursuant to the Enterprise Act 2002, and from the Portuguese competition authority, Autoridade da Concorrência, in accordance with the Portuguese Competition Law (Law No 18/2003, of 11 June).

At any time before or after the combination, the U.S. Antitrust Division of the U.S. Department of Justice and the FTC, a U.S. state attorney general, or a non-U.S. competition authority could take action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the combination or seeking divestiture of substantial assets of NYSE Group or Euronext or their subsidiaries. Private parties may also bring legal actions under the antitrust laws under certain circumstances. While NYSE Group and Euronext believe that they will receive the requisite regulatory approvals for the combination, they can give no assurance that a challenge to the combination will not be made or, if made, would be unsuccessful. Obtaining certain government approvals applicable to the exchange offer or merger is a condition to the combination. See "The Combination Agreement—Conditions to Completing the Combination—Conditions to Filing and Commencing the Exchange Offer" and "The Combination Agreement—Conditions to Completing the Exchange Offer."

Securities and Other Regulatory Authorities

European Regulators. The combination is also subject to receipt of the following approvals from European regulators:

•: the Dutch Minister of Finance shall have issued a declaration of no objection pursuant to section 26a of the Dutch Act on the Supervision of the Securities Trade 1995 allowing NYSE Euronext to acquire the Euronext shares;
•: authorization from the French Comité des Etablissements de Crédit et des Entreprises d'Investissement ("CECEI") in accordance with the provisions of Article 2 of the French Règlement CRBF No. 96-16;
•: no objection of the AMF pursuant to the provisions of Articles 511-1 and 511-5 of the General Rules of the AMF;
•: the French Minister of Economy shall have taken no steps under article 441-1 of the Code Monetaire et Financier to object to the completion of the exchange offer; and
•: authorization of Euronext's College of Regulators, which includes the Chairmen of the AMF, the Netherlands Authority for the Financial Markets (Autoriteit Financiële Markten), the Belgian Banking, Finance, and Insurance Commission (Commission Bancaire, Financière, et des Assurances), the Portuguese Securities Commission (Comissão do Mercado de Valores Mobiliários), and the U.K. Financial Services Authority.

U.S. Securities and Exchange Commission. The combination is subject to the approval of the U.S. Securities and Exchange Commission (the "SEC"). The SEC has the right to approve the rules of the U.S. securities exchanges that will be owned by NYSE Euronext, and is expected to review certain aspects of the organizational documents of NYSE Euronext and its subsidiaries to the extent that they affect these U.S. securities exchanges. The NYSE will file an application with the SEC seeking approval of certain elements of the proposed organization and operations described in this document.

Other Approvals. In addition to the regulatory approvals noted above, the combination is subject to the receipt of all other governmental approvals or the making of all other required governmental filings (including any required approvals or filings for amendments to

existing or the granting of new exchange licenses and recognitions), the failure of which to be obtained or made, individually or in the aggregate, would reasonably be expected to have a material adverse effect on NYSE Euronext, NYSE Group or Euronext.

Shareholder Approvals and Other Conditions

The combination is also subject the satisfaction or waiver of conditions in the combination agreement, including the NYSE Group stockholder approval and Euronext shareholder approval. See "The Combination Agreement—Conditions to Completing the Combination." Subject to the satisfaction or waiver of the conditions set forth in the combination agreement NYSE Group and Euronext expect to complete the combination in the first quarter of 2007.

Approvals for Certain Purchases of Euronext Shares Outside of the United States During the Exchange Offer

In connection with the combination, UBS AG and Morgan Stanley, serving as financial advisors to Euronext, have sought and received from the SEC exemptive relief from the requirements of Rule 14e-5 under the Securities Exchange Act of 1934, as amended (the "Exchange Act") that permits these financial advisors and their affiliates and separately identifiable departments to make purchases of, or arrangements to purchase, Euronext securities outside the United States other than pursuant to the exchange offer. NYSE Euronext, NYSE Group and Euronext expressly draw attention to the fact that, subject to applicable regulatory requirements, these financial advisors and their affiliates or nominees or brokers (acting as agents) have the ability to make certain purchases of, or arrangements to purchase, Euronext securities outside the United States, other than pursuant to the exchange offer, before or during the period in which the exchange offer remains open for acceptance. In the event they were made, these purchases or arrangements to purchase would only be conducted in compliance with the applicable regulations in France, any other applicable jurisdiction in which Euronext securities are listed, and applicable U.S. securities laws (except to the extent of any exemptive relief granted by the SEC).

Absence of Appraisal Rights (see page 128)

Under the Delaware general corporation law, which governs the merger, as well as under the NYSE Group certificate of incorporation and bylaws, NYSE Group stockholders are not entitled to any appraisal rights in connection with the merger.

Under Dutch and French law, as well as the Euronext articles of association, Euronext shareholders will not be entitled to appraisal rights in connection with the exchange offer or the post-closing reorganization. However, if 95% or more of the issued and outstanding share capital of Euronext is tendered in the exchange offer and NYSE Euronext elects to initiate a compulsory acquisition procedure under Dutch law, the consideration to be paid to Euronext holders in such circumstances would be determined by the Enterprise Chamber of the Amsterdam Court of Appeals. See "The Combination Agreement—Post-Closing Reorganization."

Directors and Management of NYSE Euronext Following the Combination (see page 152)

Following the combination, the NYSE Euronext board of directors will consist of 22 directors: 11 will be the directors of NYSE Group immediately prior to the combination (including both the chairman and the chief executive officer of NYSE Group), 1 will be an additional designee of NYSE Group, 9 will be members of the Euronext supervisory board immediately prior to the combination (including the chairman of the Euronext supervisory board), and 1 will be the chief executive officer of Euronext immediately prior to the combination. The initial term of the directors will end with the first annual stockholders meeting to be held by NYSE Euronext. Thereafter, the directors will serve one-year terms.

It is expected, in accordance with the combination agreement, that (i) Jan-Michiel Hessels, the current chairman of the supervisory board of Euronext, will be the chairman of the board of NYSE Euronext; (ii) Marshall N. Carter, the current chairman of the board of NYSE

Group, will be the deputy chairman of the board of NYSE Euronext; (iii) John A. Thain, the current chief executive officer and a director of the NYSE Group, will be the chief executive officer and a director of NYSE Euronext; and (iv) Jean-François Théodore, the current chief executive officer of Euronext, will be the deputy chief executive officer and a director of NYSE Euronext.

The NYSE Euronext bylaws in effect after the combination will provide that:

•: (i) the chairman of the board of directors will be a European domiciliary and the chief executive officer will be a U.S. domiciliary or (ii) the chairman of the board of directors will be a U.S. domiciliary and the chief executive officer will be a European domiciliary;
•: the board will consist of 12 directors who are U.S. domiciliaries and 10 directors who are European domiciliaries; and
•: the nominating and governance committee of the NYSE Euronext board of directors will consist of an equal number of U.S. domiciliaries and European domiciliaries.

For purposes of these requirements:

•: a person is a "U.S. domiciliary" if he or she was, at the time of his or her election to the board of directors and for the preceding 12 months, a person domiciled in the United States; and
•: a person is a "European domiciliary" if he or she was, at the time of his or her election to the board of directors and for the preceding 12 months, a person domiciled in Europe.

The above requirements cannot be changed unless approved by a resolution adopted by two-thirds of the NYSE Euronext directors then in office or by a shareholders' vote of 80% of the shares issued and outstanding.

At the completion of the combination, the management committee of NYSE Euronext will consist of up to 16 persons, including an equal number of NYSE Group designees and Euronext designees.

Third-Party Acquisition Proposals (see page 141)

Subject to certain exceptions, the combination agreement generally restricts the ability of NYSE Group and Euronext to solicit or engage in discussions or negotiations with a third-party regarding a proposal to acquire a significant interest in either entity.

Under certain circumstances, the NYSE Group board and the Euronext boards may engage in discussions or negotiations in response to a bona fide unsolicited written acquisition proposal if they conclude that there is a reasonable likelihood that such proposal could constitute a superior proposal (as defined in the combination agreement) and due compliance with their respective fiduciary duties so requires. If, prior to the NYSE stockholder approval or consummation of the exchange offer, the NYSE Group board or Euronext boards, respectively, conclude that such acquisition proposal constitutes a superior proposal and due compliance with their respective fiduciary duties so requires, then the NYSE Group board or Euronext boards, respectively, may change its or their recommendation that stockholders vote in favor of the combination agreement and the transactions contemplated by the combination agreement and, in the case of Euronext shareholders, tender their Euronext shares in the exchange offer.

Termination of the Combination Agreement; Expense Reimbursement (see page 144)

NYSE Group and Euronext may jointly agree to terminate the combination agreement at any time. Either NYSE Group or Euronext may also terminate the combination agreement in various circumstances, including, but not limited to, failure to receive necessary stockholder or shareholder approvals, failure to obtain a necessary governmental approval, failure to achieve the minimum tender condition or upon the breach by the other party of certain of its obligations under the combination agreement.

In several circumstances involving a change in the recommendation of the NYSE Group board of directors or the Euronext supervisory board or managing board in favor of the approval and

adoption of the combination agreement, or certain actions with respect to a third-party acquisition proposal, either NYSE Group or Euronext may become obligated to reimburse the other party for expenses incurred in connection with the combination. See "The Combination Agreement—Termination."

Stock Exchange Listing and Stock Prices (see page 127)

NYSE Group common stock is listed on the NYSE under the symbol "NYX." After the combination is completed, NYSE Group common stock will be delisted from the NYSE.

Euronext shares are listed on Euronext Paris (Eurolist by Euronext) under the symbol "NXT." As soon as permissible after the combination or the post-closing reorganization, if applicable, is completed, NYSE Euronext intends to request the delisting of Euronext shares from Euronext Paris (Eurolist by Euronext).

NYSE Euronext intends to apply to list the NYSE Euronext common stock issued in the combination on the NYSE under the symbol "[ • ]" and on Euronext Paris (Eurolist by Euronext) under the symbol "[ • ]" (ISIN Code [ • ]).

Certain Differences in the Rights Before and After the Combination (see page 402)

Until the completion of the combination (and in the case of Euronext shareholders that do not tender their Euronext shares in the exchange offer, the post-closing reorganization), Delaware law and the NYSE Group certificate of incorporation and bylaws will continue to govern the rights of NYSE Group stockholders, and Dutch law and the Euronext articles of association will continue to govern the rights of Euronext shareholders. After completion of the combination (or, as applicable, the post-closing reorganization), Delaware law and the NYSE Euronext certificate of incorporation and bylaws will govern the rights of NYSE Euronext stockholders. Please read carefully the forms of NYSE Euronext certificate of incorporation and bylaws that will be in effect upon completion of the combination (which forms are included as Exhibits 3.1 and 3.2, respectively, to the registration statement of which this document forms a part), as well as a summary of the material differences between the rights of NYSE Group stockholders and Euronext shareholders, on the one hand, and the NYSE Euronext stockholders, on the other hand, under "Comparison of Shareholder Rights Prior to and After the Combination."

Material differences in the rights of NYSE Group stockholders and Euronext shareholders prior to the combination, on the one hand, and the rights of NYSE Euronext stockholders after the combination, on the other hand, will include, among others, the following:

•: The NYSE Euronext bylaws will provide that the NYSE Euronext board of directors must consist of 12 U.S. domiciliaries and 10 European domiciliaries, and that the nominating and governance committee of the NYSE Euronext board of directors will consist of an equal number of U.S. domiciliaries and European domiciliaries. Under the NYSE Euronext bylaws, these requirements cannot be amended unless approved by a resolution adopted by two-thirds of the directors then in office or a shareholder vote of 80% of the shares issued and outstanding.
•: The NYSE Euronext certificate of incorporation will contain provisions prohibiting any person, either alone or together with its related persons (as defined in the NYSE Euronext certificate of incorporation and described under "Description of NYSE Euronext Capital Stock—Ownership and Voting Limits on NYSE Euronext Capital Stock"), from voting more than 10% of the outstanding capital stock, or owning more than 20% of the capital stock, of NYSE Euronext unless (i) the NYSE Euronext board resolves to expressly permit such voting or ownership in accordance with the standard for approving such voting or ownership set forth in the certificate of incorporation and (ii) such resolution has been approved by the relevant European regulators and the SEC. These limitations are similar to the voting and ownership limitations currently

imposed on NYSE Group common stock, but the Euronext shareholders are not currently subject to a similar voting and ownership limitation. Euronext shareholders are, however, currently bound by the restrictions of section 26a of the Dutch Act on the Supervision of the Securities Trade 1995 (Wet toezicht effectenverkeer 1995) pursuant to which a declaration of no objection of the Dutch Minister of Finance must be obtained in the event of any acquisition, increase in or holding of a direct or indirect interest of more than 10% of the outstanding capital or voting rights in Euronext and by similar restrictions relating to indirect ownership of certain qualifying interests or percentages of voting rights in certain regulated subsidiaries of Euronext.

Share Repurchases (see page [ • ])

Neither NYSE Group nor NYSE Euronext has any current plan or intention to repurchase any NYSE Group common stock or NYSE Euronext common stock, respectively. Euronext currently intends to implement in accordance with applicable laws and regulations the Euronext share repurchase plan that had been announced at the time of the publication of its 2005 financial statements, under the authorization granted by Euronext's annual general meeting held on May 23, 2006.

SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA

The following financial information is to assist you in your analysis of the financial aspects of the combination. The following tables present (1) selected historical financial data of NYSE Group, (2) selected historical financial data of Euronext, and (3) selected unaudited pro forma condensed consolidated financial data reflecting the combination.

Selected Historical Financial Data of NYSE Group

NYSE Group is a Delaware corporation that was formed for the purpose of consummating the business combination of the NYSE and Archipelago, which was completed on March 7, 2006. The merger of the NYSE and Archipelago has been treated as a purchase business combination for accounting purposes, with the NYSE designated as the acquirer. As such, the historical financial statements of the NYSE have become the historical financial statements of NYSE Group. Set forth below are selected historical financial data for: (1) NYSE Group; and (2) Archipelago, as predecessor to NYSE Arca and which was acquired by NYSE Group on March 7, 2006, as a result of the merger. Because the NYSE/Archipelago merger was not consummated until March 7, 2006, the following selected historical financial data for NYSE Group for periods prior to this date reflect only the NYSE's results and do not include Archipelago's results.

The following selected consolidated financial data has been derived from the historical consolidated financial statements and related notes for the years ended December 31, 2001 through December 31, 2005, and have been prepared in accordance with U.S. GAAP. The information presented here is only a summary, and it should be read together with the consolidated financial statements set forth on pages FIN-5 to FIN-85 of this document. The information set forth below is not necessarily indicative of NYSE Group's results of future operations and should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations of NYSE Group."

(1): In September 2005, Archipelago completed the acquisition of PCX Holdings and its subsidiaries for a total purchase price of approximately $94.0 million consisting of a $90.9 million cash payment to PCX Holdings stockholders and certain employees of PCX Holdings and its subsidiaries, and approximately $3.1 million of direct costs incurred by Archipelago as part of this acquisition. The results of operations of PCX Holdings have been included in Archipelago's results of operations since October 1, 2005.
(2): On August 11, 2004, prior to the consummation of its initial public offering, Archipelago Holdings L.L.C. converted from a Delaware limited liability company to a Delaware corporation, Archipelago Holdings, Inc.
(3): On March 15, 2002, Archipelago completed a merger with REDIBook ECN L.L.C., a competing electronic communication network (or "ECN"), as a result of which Archipelago significantly increased its trading volumes in Nasdaq-listed securities.
(4): Archipelago engages in a significant amount of business with related parties in the ordinary course of its business. For a discussion of Archipelago's related-party transactions, see Note 10 to Archipelago's consolidated financial statements included elsewhere in this prospectus.
(5): Archipelago pays Section 31 fees to the SEC based on fee schedules determined by the SEC and, in turn, collects activity assessment fees from equity trading permit and option trading permit holders trading on ArcaEx and the Pacific Exchange, respectively. Activity assessment fees received are included in cash and cash equivalents at the time of receipt, and, as required by law, the amount due to the SEC is recorded as an accrued liability and remitted semiannually. Following the September 2005 acquisition of PCX Holdings, activity assessment fee revenue and Section 31 fee expense are presented gross in Archipelago's statement of operations. These fees have had no impact on Archipelago's consolidated statement of operations.
(6): Following the launch of ArcaEx in March 2002, Archipelago began earning revenues from market data fees based on the level of trading activity on ArcaEx. As the operator of ArcaEx, Archipelago became eligible to participate in the sale of market data to, and the receipt of market data fees from, centralized aggregators of this information.
(7): In January 2000, Archipelago implemented an equity entitlement program under which participating customers became eligible to earn "equity entitlements" based on the volume of order flow on Archipelago's trading platforms. Equity entitlements were converted into Class B shares of Archipelago Holdings L.L.C. without additional consideration. These shares were converted into shares of Archipelago common stock in the conversion of Archipelago Holdings L.L.C. into Archipelago Holdings, Inc.
(8): In April 2002, to enhance the liquidity of its system, Archipelago began to pay a small fee per share, referred to as "liquidity payments," to participants that post certain buy orders and sell orders on the Archipelago system when the quote is executed against by other participants purchasing and selling internally on the Archipelago system. Archipelago generally does not pay these fees for orders posted on NYSE-listed securities.
(9): Archipelago undertook self-clearing initiatives of its routing broker and introducing broker businesses. Effective in January 2005, Archipelago Securities Inc. began to clear trades it routed to other market centers for execution. In addition, effective in July 2004, Archipelago Securities, Inc. began to clear trades effected by non-ETP broker-dealer customers accessing ArcaEx through Archipelago Trading Services. In addition, due to the lower percentage of orders routed out to other market centers, Archipelago's number of trades subject to clearing costs has decreased.
(10): In connection with its merger with the NYSE, Archipelago incurred legal, banking, regulatory and other fees in 2005. In addition, Archipelago incurred certain executive compensation expenses as a result of the acceleration of payments to, and vesting of restricted stock units of, Archipelago officers in 2005.
(11): As a limited liability company, all income taxes were paid by the members of Archipelago. As a corporation, Archipelago is responsible for the payment of all U.S. federal, state and local corporate income taxes.
(12): As part of a proposed rule change filed by the Pacific Exchange with the SEC, Archipelago undertook to divest Wave Securities L.L.C., a wholly owned subsidiary of Archipelago providing agency brokerage services. The results of operations and financial position of Wave Securities are presented as discontinued operations in the consolidated financial statements. All historical periods presented have been restated to reflect such presentation. Archipelago completed the sale of Wave Securities on March 3, 2006.

(13): In August 2004, in connection with its initial public offering, Archipelago converted 16,793,637 Class A preferred shares of Archipelago (sold to GAP Arca Holdings, L.L.C., an affiliate of General Atlantic, on November 12, 2003 for total consideration of $50.0 million) into 4,449,268 shares of Archipelago common stock. Included in this conversion was the issuance of 717,349 shares of common stock attributable to a $9.6 million beneficial conversion feature included in the previously issued redeemable preferred interest.
(14): In August 2004, in connection with Archipelago's reorganization, the members of Archipelago Holdings L.L.C. received 0.222222 shares of Archipelago common stock for each membership held by the member in Archipelago Holdings L.L.C. The weighted average number of shares used in the basic and diluted earnings per share computations gives retroactive effect to this 4.5-for-1 reverse stock split.
(15): As approved by the board of managers of Archipelago Holdings L.L.C. on July 16, 2004, Archipelago Holdings L.L.C. made a cash distribution to its members immediately prior to the conversion transaction. The cash distribution provided funds to the members to permit them to pay taxes that the members owe for their share of Archipelago's profits in 2004 as a limited liability company through the date of the conversion transaction, calculated primarily based on the highest federal and state income tax rate applicable for tax withholding purposes to an individual. The cash distribution was approximately $24.6 million and resulted in a corresponding reduction to cash and cash equivalents. As used in this discussion, the term "members" refers to the former owners of Archipelago Holdings L.L.C.
(16): In August 2004, Archipelago completed its initial public offering and sold 6,325,000 shares of Archipelago common stock at $11.50 per share. Archipelago received net proceeds of $67.6 million and incurred approximately $6.8 million in expenses in connection with its initial public offering.

(1): In January 2002, Euronext acquired all the outstanding shares of LIFFE (Holdings) plc. The total consideration paid amounted to € 926 million, including the cash settlement of outstanding options and warrants and including acquisition costs. Total goodwill in relation to the acquisition amounted to €647 million. In addition to own funds used for an amount of €476 million, the transaction was financed by a credit facility of GBP 250 million (€409 million), and the issuance of Variable Rate Guaranteed Unsecured Loan Notes for an amount of €27 million. The remainder of the loan facility (GBP 150 million) was redeemed in February 2004 with the proceeds of a GBP 250 million, fixed-rate bond loan issued also in February 2004. At the same time the fixed rate was swapped to floating rate by means of an interest rate swap. The assets, liabilities, results and cash flows of LIFFE have been included in the consolidated accounts of Euronext as from January 1, 2002.
(2): In January 2002, Euronext acquired 100% of the shares of Bolsa de Valores de Lisboa e Porto (BVLP). The total consideration paid, based on the Euronext share price at the time of the acquisition and including acquisition costs, amounted to €138 million. The consideration was paid partly in cash (€35 million) and partly in newly issued Euronext shares (4.8 million shares). The assets, liabilities, results and cash flows of BVLP have been included in the consolidated accounts of Euronext as from January 1, 2002.

(3): In June 2003, Euronext reached an agreement with the London Clearing House (LCH) to merge BCC/Clearnet and LCH into a new independent UK holding company LCH.Clearnet Group Ltd. On December 22, 2003, Euronext exchanged its 80% stake in BCC/Clearnet and its 17.7% interest in LCH for 49.1% of LCH.Clearnet Group. Simultaneously, Euronext sold 7.6% of these shares to third parties. Euronext's 41.5% interest in LCH.Clearnet Group is divided into ordinary shares (24.9%) and Redeemable Convertible Preference Shares (16.6%). Euronext recorded a gain on disposal of discontinued operation of €175 million in connection with the transaction. As from December 22, 2003, Euronext no longer records clearing revenues, but instead accounts for its interest in LCH.Clearnet under the equity method, recording its share of income under "Income from associates".
(4): On July 22, 2005, Euronext formed Atos Euronext Market Solutions as a continuation and expansion of its pre-existing Atos Euronext relationship with Atos Origin. The main assets Euronext contributed were the activities of LIFFE Market Solutions, the information technology division of its derivatives trading business Euronext.liffe, and its 50% stake in Atos Euronext. Atos Origin contributed its own 50% share in Atos Euronext, plus other major assets from market-related businesses, including middle-and back-office solutions, and its 51% stake in the connectivity platform Bourse Connect. The transfer of the activities of LIFFE Market Solutions to AEMS led to a significant reduction in Euronext's salaries and employee benefit costs, consultancy expenses, other office, telecom and consultancy costs and depreciation charges, and a parallel increase in IT expenses, which from the date of creation of AEMS include all IT expenses related to Euronext.liffe.
(5): In January 2006, Euronext completed the sale of the Belgian central securities depository CIK NV/SA, a wholly-owned subsidiary of Euronext Brussels, to Euroclear. In exchange for this asset, Euronext received an additional 0.4% stake in Euroclear.
(6): As from January 1, 2005, Euronext no longer amortizes goodwill relating to acquisitions made before March 31, 2004 as part of a business combination, in line with IFRS 3.

COMPARATIVE HISTORICAL AND PRO FORMA PER SHARE DATA
(Unaudited)

Set forth below are historical and pro forma amounts, per share of NYSE Group common stock and per Euronext share, of income from continuing operations, cash dividends and book value. The exchange ratio for the pro forma computations is one share of NYSE Euronext common stock for each share of NYSE Group common stock, and €21.32 in cash and 0.98 of a share of NYSE Euronext common stock for each Euronext share.

The following table also sets forth combined per share data on an unaudited pro forma condensed consolidated basis. The pro forma amounts were derived using the purchase method of accounting for business combinations as described under "Unaudited Pro Forma Condensed Combined Financial Data for NYSE Euronext." In accordance with Emerging Issues Task Force No. 99-12, Determination of the Measurement Date for the Market Price of Acquirer Securities Issued in a Purchase Business Combination, the fair value of NYSE Euronext securities to be issued to Euronext shareholders to effect the combination will be based on a stock price of $61.70 per share, which corresponds to the average closing stock price of a NYSE Group common stock for the five-day period beginning two days before and ending two days after June 1, 2006 (the date the combination was agreed to and announced), and not the price of a Euronext share when the combination is completed. The closing price of a NYSE Group share on September 19, 2006 was $66.67 per share.

COMPARATIVE PER SHARE MARKET INFORMATION

The following table sets forth the closing market price per share of NYSE Group common stock and per Euronext share in U.S. dollars or euros, as the case may be, as reported on the NYSE for NYSE Group common stock and as reported on Euronext Paris (Eurolist by Euronext) for the Euronext shares. In each case, the prices are given:

•: as of May 31, 2006 (the last business day prior to the date of public announcement of the execution of the combination agreement);
•: as of [ • ], 2006 (the latest practicable trading date prior to the date of this document).

See "The Combination—Stock Exchange Listing and Stock Prices" for further information about the historical market prices of these securities.

The table also presents the implied equivalent value of each Euronext share based on the standard offer consideration of €21.32 in cash and 0.98 of a share of NYSE Euronext common stock for each Euronext share. For purposes of calculating the implied value of a Euronext share as of any particular date, each share of NYSE Euronext common stock was assumed to have a value equal to the closing market price per share of NYSE Group common stock on such date, as reported on the NYSE, and such value was converted into euros at a rate of €1.00 = $1.2833, which was the Federal Reserve Bank of New York noon buying rate on May 31, 2006, or at a rate of €1.00 = $[ • ], which was the Federal Reserve Bank of New York noon buying rate on [ • ], 2006, as applicable.

You are urged to obtain current market quotations for shares of NYSE Group common stock and Euronext shares before making your decision with respect to the approval and adoption of the combination agreement. NYSE Group's common stock is listed on the New York Stock Exchange under the symbol "NYX." Euronext shares are listed on Euronext Paris (Eurolist by Euronext) under the symbol "NXT."

The market price of NYSE Group common stock or Euronext shares could change significantly and may not be indicative of the value of shares of NYSE Euronext common stock once they start trading. Because the exchange ratios will not be adjusted for changes in the market price of NYSE Group common stock or Euronext shares, the value of the shares of NYSE Euronext common stock that you will receive at the time of completion of the combination may vary significantly from the market value of the shares of NYSE Euronext common stock that you would have received if the combination were consummated on the date of the combination agreement or on the date of this document.

EXCHANGE RATE INFORMATION

The following tables show, for the periods indicated, information concerning the exchange rate between the U.S. dollar and the euro. The average rates for the monthly periods presented in these tables were calculated by taking the simple average of the daily noon buying rates, as published by the Federal Reserve Bank of New York. The average rates for the interim periods and annual periods presented in these tables were calculated by taking the simple average of the noon buying rates on the last day of each month during the relevant period. This information is provided solely for your information, and neither NYSE Group nor Euronext represent that euros could be converted into U.S. dollars at these rates or at any other rate. These rates are not the rates used by Euronext in the preparation of their respective consolidated financial statements incorporated by reference into this prospectus.

The data provided in the following table are expressed in U.S. dollars per euro and are based on noon buying rates published by the Federal Reserve Bank of New York for the euro. On May 31, 2006, the date immediately prior to the announcement of the combination, the exchange rate between the U.S. dollar and the euro expressed in U.S. dollar per euro was €1.00 = $1.2833. On [ • ], the most recent practicable date prior to the printing of this prospectus, the exchange rate was €1.00 = $[ • ].

RISK FACTORS

In addition to the other information contained in this document, including the matters addressed under "Forward-Looking Statements," you should carefully consider the following risk factors.

Risks Relating to the Combination

Because the exchange ratio in the merger and exchange offer are fixed, the market value of the consideration paid to you in the combination may be less than the market value of your NYSE Group common stock or Euronext shares.

NYSE Group stockholders and Euronext shareholders who receive shares in the combination will receive a fixed number of shares of NYSE Euronext common stock (and, in the case of the Euronext shareholders, a fixed amount of cash) rather than a number of shares with a particular fixed market value. The market value of NYSE Group common stock and Euronext shares at the time of the combination or the post-closing reorganization may vary significantly from their prices on the date of the combination agreement, the date of this document, the date on which NYSE Group stockholders or Euronext shareholders vote on the combination, or the date on which Euronext shareholders tender their shares in the exchange offer or the date of the consummation of the merger, the exchange offer or the post-closing reorganization. Because the exchange ratios will not be adjusted to reflect any changes in the market price of NYSE Group common stock or Euronext shares, the value of the consideration paid to the NYSE Group stockholders in the merger and the Euronext shareholders who tender their shares in the exchange offer may be higher or lower than the market value of their shares on earlier dates.

Changes in stock price may result from a variety of factors that are beyond the control of NYSE Group and Euronext, including changes in their respective businesses, operations and prospects, regulatory considerations, governmental actions, and legal proceedings and developments. Market assessments of the benefits of the combination and of the likelihood that the combination will be completed, and general and industry specific market and economic conditions may also have an effect on prices. Neither NYSE Group nor Euronext is permitted to terminate the combination agreement solely because of changes in the market price of either party's shares. See "The Combination Agreement—Termination" for a description of the circumstances in which NYSE Group and Euronext may terminate the combination agreement and "The Combination Agreement—Third-Party Acquisition Proposals" for a description of the circumstances in which NYSE Group and Euronext may respond to acquisition proposals received from third parties.

In addition, it is possible that the combination and the post-closing reorganization may not be completed until a significant period of time has passed after the shareholder meetings. As a result, the market values of NYSE Group common stock and Euronext shares may vary significantly from the date of the shareholder meetings to the date of the completion of the combination. You are urged to obtain up-to-date prices for NYSE Group common stock and Euronext shares. See "The Combination—Stock Exchange Listing and Stock Prices" for ranges of historic prices of shares of NYSE Group common stock and Euronext shares.

If you are a Euronext shareholder, your ability to increase the amount of cash or the number of shares of NYSE Euronext common stock that you receive in the exchange offer pursuant to the cash election or stock election, respectively, will be subject to proration in the event of an oversubscription of the cash election or the stock election.

paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued, respectively, if all exchanging Euronext shareholders received the standard offer consideration.

As a result, the consideration that any particular Euronext shareholder receives if he or she makes the cash election or the stock election will not be known at the time that he or she makes the election because the consideration will depend on the total number of Euronext shareholders who make the cash election and the total number of Euronext shareholders who make the stock election. If the cash election is oversubscribed, then Euronext shareholders who have made the cash election will receive some shares of NYSE Euronext common stock in lieu of the full amount of cash sought for their Euronext shares. Likewise, if the stock election is oversubscribed, then Euronext shareholders who have made the stock election will receive some cash in lieu of the full number of shares of NYSE Euronext common stock sought for their Euronext shares. Accordingly, if Euronext shareholders make the stock election or the cash election with respect to their Euronext shares, and if either is oversubscribed, they may not receive exactly the amount and type of consideration that they elected to receive in the exchange offer, which could result in, among other things, tax consequences that differ from those that would have resulted if they had received the form of consideration that they had elected.

Because there is no way to predict the market value of shares of NYSE Euronext common stock after the combination, if you are a Euronext shareholder, the value of the consideration that you will receive in the exchange offer may vary depending on the type of election that you make. Euronext shareholders who make the cash election or stock election will receive, subject to proration, a different amount of cash and number of shares of NYSE Euronext common stock than the standard offer consideration, based on an implied cash value per share of NYSE Euronext common stock equal to the volume weighted average price of a share of NYSE Group common stock during the 10 consecutive trading days ending the day immediately prior to the date of filing the exchange offer with the AMF. This implied cash value, however, may be different from the actual market value of a share of NYSE Euronext common stock upon completion of the exchange offer. As a result, the value of the consideration received by Euronext shareholders who make any particular election may vary from the value of the consideration received by Euronext shareholders who make a different election or no election.

For a discussion of the election mechanism and possible proration for those who make the cash election or stock election, see "The Combination Agreement—The Exchange Offer—Consideration Offered to Euronext Shareholders" and "The Combination Agreement—The Exchange Offer—Mix and Match Election."

If the exchange offer is successful, but some Euronext shares remain outstanding, the liquidity and market value of these Euronext shares held by the public could be adversely affected by the fact that they will be held by a small number of holders.

Depending upon the number of Euronext shares tendered in the exchange offer, following the successful completion of the exchange offer, Euronext shares may no longer meet the requirements of Euronext Paris for continued listing. Moreover, to the extent permitted under applicable law and stock exchange regulations, NYSE Euronext intends to request the delisting of Euronext shares, which are listed on Euronext Paris (Eurolist by Euronext). Such delisting may also occur because of certain actions taken in connection with the post-closing reorganization.

If the Euronext shares are delisted from Euronext Paris (Eurolist by Euronext) but the post-closing reorganization has not yet been completed and Euronext shares remain outstanding, the market for Euronext shares could be adversely affected. Although it is possible that Euronext shares would be traded in over-the-counter markets prior to the post-closing reorganization, such alternative trading markets may

not occur. In addition, the extent of the public market for the Euronext shares and the availability of market quotations would depend upon the number of holders and/or the aggregate market value of Euronext shares remaining at such time, as well as the interest in maintaining a market in Euronext shares on the part of securities firms. If Euronext shares are delisted, Euronext could also cease making disclosures and reports required for listed or publicly-traded companies, which could further impact the value of the Euronext shares. To the extent the availability of such continued listings or quotations depends on steps taken by Euronext or NYSE Euronext, Euronext or NYSE Euronext may or may not take such steps. Therefore, you should not rely on any such listing or quotation or trading being available.

If the exchange offer is successful, holders that did not tender their Euronext shares in the exchange offer may not have the option of making the mix and match election, and the consideration that they receive in the post-closing reorganization may be substantially different in form and/or value than the consideration that they would have received had they tendered their Euronext shares in the exchange offer (and they may also be subject to additional taxes).

In the post-closing reorganization, Euronext shareholders that did not exchange their Euronext shares in the exchange offer will generally receive the same consideration that they would have received had they tendered their Euronext shares in the exchange offer and not made either the cash election or the stock election. They will not have the option of making either the cash election or the stock election and therefore will not be able to change the mix of cash and shares of NYSE Euronext common stock they receive in the post-closing reorganization. Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer. In addition, if the post-closing reorganization is the subject of litigation, consummation of the post-closing reorganization could be delayed. In the event of delay, the value of NYSE Euronext stock received in the post-closing reorganization when it is completed may have varied and may be higher or lower than the value of such shares at the time of the offer.

In addition, in the event that 95% or more of the issued and outstanding share capital of Euronext is tendered in the exchange offer, NYSE Euronext may at its option effectuate the post-closing reorganization by initiating a compulsory acquisition procedure (uitkoopregeling) in accordance with section 2:92a of the Dutch Civil Code. In such circumstances, the price to be paid for the Euronext shares acquired in such compulsory acquisition would be cash only, in an amount determined by the Enterprise Chamber of the Amsterdam Court of Appeals, which may be in an amount that is substantially more or less than the value of the consideration that Euronext shareholders received in the exchange offer.

For more information on the post-closing reorganization and the Dutch tax consequences associated with it, see "The Combination Agreement—Post-Closing Reorganization" and "The Combination—Material Dutch Tax Consequences—Post-Closing Reorganization Effectuated Other Than Pursuant To The Compulsory Acquisition Procedure—Dividend Withholding Tax."

If you are a NYSE Group stockholder, the value of the NYSE Euronext common stock that you receive in the merger may change if NYSE Euronext determines to increase the exchange offer consideration paid to holders of Euronext shares.

If the proposed combination is approved, and the exchange offer is successful, NYSE Group stockholders will receive in the merger one share of NYSE Euronext common stock for each of their

shares of NYSE Group common stock. The value of the NYSE Euronext common stock that the NYSE Group stockholders will receive in the merger will depend on, among other things, the number of NYSE Euronext shares issued and the amount of cash paid to the Euronext stockholders in the exchange offer. The standard exchange offer consideration is €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. It is possible, however, that NYSE Euronext may determine at a later date to increase the exchange offer consideration, in the form of additional cash, additional shares of NYSE Euronext common stock, or both. If NYSE Euronext increases the cash consideration, it may have additional indebtedness or less cash after the completion of the combination. If NYSE Euronext increases the stock consideration, NYSE Group stockholders will have a lower percentage interest in NYSE Euronext after completion of the combination. If NYSE Euronext decides to increase the exchange offer consideration, it will not resolicit approval from the NYSE Group stockholders. Accordingly, if you are a NYSE Group stockholder, there is risk that the value of the consideration that you receive in the merger will be less than the value of the consideration that you expected to receive as of the date of this document or as of the date of the NYSE Group special meeting.

NYSE Euronext may not be able to successfully integrate the businesses and operations of NYSE Group and Euronext in a timely fashion or at all.

NYSE Group and Euronext operate as independent companies, and will continue to do so until the completion of the combination. Following the combination, NYSE Group and Euronext are committed to a policy of decentralized management under which their respective operating subsidiaries, including the exchanges, will have autonomy in respect of day-to-day operating decisions. NYSE Euronext expects that this approach will ease some of the challenges of integration. Nonetheless, NYSE Euronext expects to integrate certain of the management and technological functions of NYSE Group and Euronext. NYSE Euronext management may face significant challenges in integrating the two companies' technologies, organizations, procedures, policies and operations, as well as in addressing differences in the business cultures of the two companies, and retaining key NYSE Group and Euronext personnel. The integration process may prove to be complex and time consuming and require substantial resources and effort. It may also disrupt each company's ongoing businesses, which may adversely affect NYSE Euronext's relationships with market participants, employees, regulators and others with whom NYSE Group and Euronext have business or other dealings.

The recent merger of the NYSE and Archipelago, which was completed on March 7, 2006, may add further challenges and complexity. NYSE Group is currently in the process of integrating the businesses of the NYSE and Archipelago, and this process is not expected to be completed before the completion of the combination. In addition, NYSE Group is currently in discussions with the American Stock Exchange ("AMEX") to acquire AMEX's one-third ownership interest in Securities Industry Automation Corporation ("SIAC"). NYSE Group currently owns the remaining two-thirds interest. As a result, NYSE Euronext's management may have to integrate the businesses of the NYSE, Archipelago, SIAC and Euronext simultaneously, which may be difficult. If NYSE Euronext fails to manage the integration of these businesses effectively, its growth strategy and future profitability could be negatively affected, and it may fail to achieve the anticipated benefits of the combination. In addition, difficulties in integrating these businesses could harm NYSE Euronext's reputation.

The combined company may fail to realize the anticipated cost savings, growth opportunities and synergies and other benefits anticipated from the combination.

The success of the combination will depend, in part, on NYSE Euronext's ability to realize anticipated cost savings, revenue synergies and growth opportunities from combining the businesses of NYSE Group and Euronext. NYSE Euronext expects to benefit from operational synergies resulting from the consolidation of capabilities and elimination of redundancies as well as greater efficiencies from increased scale, market integration and automation. Specifically, NYSE Group and Euronext expect that the

combined company will achieve cost savings of approximately $275 million annually within three years after the combination (with approximately $55 million of these cost savings achieved by the end of the first year, $125 million by the end of the second year and the full $275 million by the end of the third year). Of this amount, an estimated $250 million is expected to result from the overall rationalization of the combined company's information technology systems and platforms, driven by the high level of compatibility among the current technology platforms maintained by NYSE Group and Euronext, and the remaining $25 million is expected to result from the rationalization of non-information technology related activities, including the integration of corporate support functions such as finance, and the streamlining of marketing and other corporate costs such as insurance, occupancy and professional services.

NYSE Group and Euronext also expect that the combination will create approximately $100 million in incremental revenues annually within three years after the combination. Of this amount, approximately $35 million is expected to be generated from cash equities trading, $45 million is expected to be generated from derivatives and the remaining $20 million is expected to be generated from listing fees. For more information about these projections, see "The Combination—Certain Projections" and "Information About NYSE Euronext—NYSE Euronext's Strategy."

There is a risk, however, that the businesses of NYSE Group and Euronext may not be combined in a manner that permits these costs savings and revenue synergies to be realized in the time currently expected, or at all. For example, the completion of the combination and the post closing may be delayed or challenged by parties opposing the completion of the combination or the post-closing reorganization. This may limit or delay the NYSE Euronext management's ability to integrate the two companies' technologies, organizations, procedures, policies and operations. In addition, a variety of factors, including but not limited to wage inflation, currency fluctuations, and difficulty integrating technology platforms, may adversely affect NYSE Euronext's anticipated cost savings and revenues. Also, the combined company must achieve its anticipated cost savings without adversely affecting its revenues. If NYSE Euronext is not able to successfully achieve these objectives, the anticipated benefits of the combination may not be realized fully, or at all, or may take longer to realize than expected.

NYSE Euronext's results of operations may differ significantly from the unaudited pro forma condensed combined financial data included in this document.

This document includes unaudited pro forma condensed combined financial data giving effect to the combination of the NYSE, Euronext, Archipelago and PCX Holdings as if it had occurred as of January 1, 2005. This pro forma financial information is presented for illustrative purposes only and does not necessarily indicate the results of operations or the combined financial position that would have resulted had the combination been completed at the beginning of the periods presented, nor is it indicative of the results of operations in future periods or the future financial position of the combined businesses. In particular, it does not reflect benefits of expected costs savings or revenue opportunities with respect to the combination of the NYSE Group and Euronext. Accordingly, NYSE Euronext's results and financial condition may differ significantly from those portrayed by the unaudited pro forma condensed combined financial data included herein.

NYSE Euronext, NYSE Group and Euronext will incur significant transaction and combination-related costs in connection with the combination.

NYSE Group and Euronext expect to incur a number of non-recurring costs associated with combining the operations of the two companies, anticipated to be approximately $70 million in each of 2007 and 2008 and $40 million in 2009. In addition, NYSE Group and Euronext will incur legal, accounting and other transaction fees and other costs related to the combination, anticipated to be between $50 million and $75 million. Some of these costs are payable regardless of whether the combination is completed. Moreover, under specified circumstances, NYSE Group or Euronext may be required to

reimburse certain expenses incurred by the other party in connection with the termination of the proposed combination. See "The Combination Agreement—Termination—Expense Reimbursement." Additional unanticipated costs may be incurred in the integration of the businesses of the NYSE Group and Euronext.

Although NYSE Euronext expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may offset these transaction- and combination-related costs over time, this net benefit may not be achieved in the near term, or at all.

If the combination is successful, NYSE Euronext will incur a substantial amount of debt to finance the cash portion of the consideration for the Euronext shares to be acquired, which could restrict its ability to engage in additional transactions or incur additional indebtedness.

In connection with the exchange offer, NYSE Euronext will enter into a credit facility agreement that permits NYSE Euronext to borrow amounts sufficient to fund the cash portion of the exchange offer, which is expected to be $3.0 billion. NYSE Euronext may only borrow amounts under this credit facility agreement if the combination is successful. If the combination is successful, NYSE Euronext expects to use the credit facility as an undrawn back stop for a Global Commercial Paper Program, which NYSE Euronext will use mainly to finance the cash portion of the consideration to be paid to Euronext shareholders pursuant to the exchange offer. The credit facility includes terms and conditions customary for agreements of this type, which could restrict NYSE Euronext's ability to engage in additional transactions or incur additional indebtedness.

There will be material differences between the current rights of NYSE Group stockholders and Euronext shareholders and the rights they can expect to have as NYSE Euronext stockholders.

NYSE Group stockholders and Euronext shareholders that receive NYSE Euronext common stock in the combination will become NYSE Euronext stockholders, and their rights as stockholders will be governed by the NYSE Euronext certificate of incorporation and bylaws and by Delaware law. As a result, there will be material differences between the current rights of NYSE Group stockholders and Euronext shareholders and the rights they can expect to have as NYSE Euronext stockholders. For example, there is no current domicile requirement for directors of NYSE Group or Euronext. After the combination, the NYSE Euronext bylaws will provide that the NYSE Euronext board of directors will be composed of 12 persons, who at the time of, and for the preceding 12 months prior to, being elected to the board were domiciled in the United States (a "U.S. domiciliary"), and 10 persons, who at the time of, and for the preceding 12 months prior to, being elected to the board were domiciled in Europe (a "European domiciliary"). In addition, the bylaws will provide that the nominating and governance committee of the NYSE Euronext board of directors will be composed of an equal number of individuals who are U.S. domiciliaries and European domiciliaries. Furthermore, the bylaws will provide that the positions of chairman of the board of directors and chief executive officer of NYSE Euronext will be filled by one person who is a U.S. domiciliary and one person who is a European domiciliary. These requirements cannot be changed unless approved by a resolution adopted by two-thirds of the directors then in office or a shareholder vote of 80% of the shares issued and outstanding.

Another difference will be the voting and ownership limitations on NYSE Euronext common stock. The NYSE Euronext certificate of incorporation will contain provisions prohibiting any person, acting either alone or together with its related persons (as defined in the NYSE Euronext certificate of incorporation and described under "Description of NYSE Euronext Capital Stock—Ownership and Voting Limits on NYSE Euronext Capital Stock"), from voting more than 10% of the outstanding capital stock, or owning more than 20% of the capital stock, of NYSE Euronext unless (i) the NYSE Euronext board resolves to expressly permit such voting or ownership in accordance with the standard for approving such voting or ownership set forth in the NYSE Euronext certificate of incorporation and (ii) such resolution has been approved by the relevant European regulators and the SEC. These limitations are similar to the

voting and ownership limitations currently imposed on NYSE Group common stock. Euronext shareholders are currently subject to a different voting and ownership limitation. Pursuant to section 26a of the Dutch Act on the Supervision of the Securities Trade 1995 (Wet toezicht effectenverkeer 1995), a Euronext shareholder must obtain a declaration of no objection of the Dutch Minister of Finance in order to hold, directly or indirectly an interest of more than 10% of the outstanding capital or voting rights in Euronext. Similar restrictions also apply with respect to indirect ownership of qualifying interests or specific percentages of voting rights in certain regulated subsidiaries of Euronext (See "Regulation—European Regulation").

For a discussion of these and other material differences between the current rights of NYSE Group stockholders and Euronext shareholders and the rights they can expect to have as NYSE Euronext stockholders, see "Comparison of Shareholder Rights Prior to and After the Combination."

If you hold shares of NYSE Group common stock subject to certain transfer restrictions immediately prior to the merger, the shares of NYSE Euronext common stock that you receive in the merger in respect of those shares will be subject to the same transfer restrictions, which may prevent you from realizing gains during certain time periods.

Certain shares of NYSE Group common stock are currently subject to transfer restrictions as a result of restrictions set forth in the NYSE Group certificate of incorporation or agreements with the NYSE in connection with its merger with Archipelago. Any such shares that continue to be subject to transfer restrictions as of immediately prior to the merger will be exchanged in the merger for shares of NYSE Euronext common stock with the same transfer restriction (both in terms of scope and remaining duration). During the duration of these transfer restrictions, holders of these shares of NYSE Euronext common stock will be precluded from realizing any gains from the increase in the market price, if any, of these shares of NYSE Euronext common stock. For details of these transfer restrictions see "Description of NYSE Euronext Capital Stock—Transfer Restrictions on Certain Shares of NYSE Euronext Common Stock." No NYSE Euronext common stock received by Euronext shareholders in the combination will be subject to these transfer restrictions.

NYSE Group stockholders and Euronext shareholders will have a reduced ownership and voting interest after the combination and will exercise less influence over management.

After the completion of the combination, the NYSE Group stockholders and Euronext shareholders will own a smaller percentage of NYSE Euronext than they currently own of NYSE Group and Euronext, respectively. Upon completion of the combination, and assuming that all of the outstanding Euronext shares are validly tendered in the exchange offer and not withdrawn, former NYSE Group stockholders and former Euronext shareholders will own approximately 59% and 41%, respectively, of the outstanding common stock of NYSE Euronext immediately after the combination. Consequently, NYSE Group stockholders, as a group, will have reduced ownership and voting power in the combined company compared to their ownership and voting power in NYSE Group, and Euronext shareholders, as a group, will have reduced ownership and voting power in the combined company compared to their ownership and voting power in Euronext.

Obtaining required approvals may delay or prevent completion of the combination or reduce the anticipated benefits of the combination.

Completion of the combination is conditioned upon, among other things, the receipt of material governmental authorizations, consents, orders and approvals, including the approval of the SEC and certain European regulators. NYSE Group and Euronext intend to pursue all required approvals in accordance with their obligations under the combination agreement. In connection with granting these approvals, the respective governmental or other authorities may impose conditions on, or require

divestitures or other changes relating to, the divisions, operations or assets of NYSE Group or Euronext. For example, the SEC and the European regulators may require changes to the structure, certificate of incorporation or bylaws of NYSE Euronext and its subsidiaries, as a precondition to their approval of the combination. Neither NYSE Group nor Euronext can predict what, if any, changes may be required. Certain changes may require NYSE Group or Euronext to obtain the approval of their respective shareholders and, therefore, to re-solicit proxies, which may result in significant additional expenses and costs. More generally, these and other conditions, divestitures or other changes may jeopardize or delay completion of the combination or may reduce the anticipated benefits of the combination. See "The Combination Agreement—Conditions to Completing the Combination" for a discussion of the conditions to the completion of the combination and "The Combination—Regulatory Approvals" for a description of the regulatory approvals necessary in connection with the combination.

Risks Relating to NYSE Euronext's Business

NYSE Euronext will face numerous competitors in the United States, Europe and the rest of the world.

NYSE Euronext will face significant competition, in particular with respect to securities trading, listings and derivatives business, and this competition is expected to intensify in the future. NYSE Euronext's current and prospective competitors in this realm, both domestically and around the world, are numerous and include both traditional and non-traditional execution and listings venues. These include regulated markets, electronic communications networks ("ECNs") and other alternative trading systems, market makers and other execution venues. NYSE Euronext also will face significant and growing competition from large brokers and customers that have the ability to divert trading volumes and derivatives business from NYSE Euronext. Large banks may assume the role of principal and act as counterparty to orders originating from retail customers, thus "internalizing" order flow that would otherwise be transacted on exchanges. Banks and brokers may also enter into bilateral trading arrangements by matching their respective order flows, depriving NYSE Euronext of potential trading volumes. The competitive significance in Europe of these varied alternate trading venues is likely to increase substantially in the future, with the regulatory environment in Europe becoming more favorable to off-exchange trading as a result of the reforms contained in the European Commission's Market in Financial Instruments Directive (or "MiFID"). MiFID is expected to come into effect on November 1, 2007, although individual European Union Member States are required to incorporate MiFID into their domestic legal regimes by January 31, 2007. See "Risk Factors—Risks Relating to NYSE Euronext's Business—The implementation of the European Directive on Markets in Financial Instruments, or MiFID, may accelerate the development of off-exchange trading in Europe, which may harm NYSE Euronext's competitive position."

NYSE Euronext will compete with such market participants in a variety of ways, including the cost, quality and speed of trade execution, liquidity, the functionality, ease of use and performance of trading systems, the range of products and services offered to trading participants and listed companies, technological innovation and reputation. NYSE Euronext's competitors may:

•: respond more quickly to competitive pressures because they are not subject to the same degree of regulatory oversight as NYSE Euronext will be;
•: develop products that are preferred by NYSE Euronext customers;
•: price their products and services more competitively;
•: develop and expand their network infrastructure and service offerings more efficiently;
•: utilize faster, more user-friendly technology;

•: consolidate and form alliances, which may create greater liquidity, lower costs and better pricing than NYSE Euronext will be able to offer;
•: market, promote and sell their products and services more effectively; and
•: better leverage existing relationships with customers and alliance partners or better exploit brand names to market and sell their services.

NYSE Euronext may also face competition from new entrants into the markets in which it competes. The emergence of new competitors may increase price competition and reduce margins for all existing securities markets, including NYSE Euronext's securities markets. New entrants may include new alternative trading systems and new initiatives by existing market participants, including established securities markets or exchanges, and current customers of the NYSE Group and Euronext that may internalize some of their order flow in the future.

Globalization, growth, consolidations and other strategic arrangements may impair NYSE Euronext's competitive position.

The liberalization and globalization of world markets have resulted in greater mobility of capital, greater international participation in local markets and more competition among markets in different geographical areas. As a result, the competition among trading markets and other execution venues has become more intense.

In addition, in the last several years, the structure of the exchange sector has changed significantly through demutualizations and consolidations. In response to increasing competition, many marketplaces in both Europe and the United States have demutualized to provide greater flexibility for future growth. The exchange sector is also experiencing consolidation, creating a more intense competitive environment. For example, in the United States, Nasdaq recently completed its acquisition of INET ECN (INET). Each of the Chicago Stock Exchange, Inc., Philadelphia Stock Exchange, Inc., Boston Stock Exchange, Inc., International Securities Exchange and Chicago Board Options Exchange, Inc. have also recently entered into investment agreements with other participants in the exchange sector, with the objective of enabling them to better compete with other exchanges. In Europe, the consolidation of OMX Group, created by the merger of OM Gruppen and HEX, with the Copenhagen Stock Exchange was completed early in 2005. Furthermore, discussions were held in 2005 and 2006 as to the potential acquisition of the London Stock Exchange plc by each of Euronext, Deutsche Börse and Australia's Macquarie Bank. In March 2006, Nasdaq made an offer for the London Stock Exchange, which it subsequently withdrew. It subsequently acquired a 25.3% stake in the London Stock Exchange. It is anticipated that the process of consolidation in the European exchange sector will continue.

Because of these market trends, NYSE Euronext faces intense competition. If it is unable to compete successfully in this environment, its business, financial condition and operating results will be adversely affected.

Future business combinations, acquisitions, partnerships and joint ventures may require significant resources and/or result in significant unanticipated costs or liabilities.

NYSE Euronext may seek to grow its company and businesses by entering into business combination transactions, making acquisitions or entering into partnerships or joint ventures, which may be material. The market for acquisition targets and strategic alliances is highly competitive, particularly in light of increasing consolidation in the exchange sector, which may adversely affect NYSE Euronext's ability to find acquisition targets or strategic partners consistent with its objectives.

In pursuing its strategy, consistent with industry practice, NYSE Euronext may routinely engage in discussions with industry participants regarding potential strategic transactions. Such transactions may be financed by the issuance of additional equity securities, including NYSE Euronext common stock, or the incurrence of indebtedness, or a combination thereof. The issuance of additional equity may be substantial and dilutive to existing NYSE Euronext stockholders. In addition, the announcement or completion of future transactions could have a material adverse effect on the price of NYSE Euronext common stock. NYSE Euronext could face financial risks associated with incurring indebtedness such as reducing its liquidity, curtailing its access to financing markets and requiring the service of such indebtedness.

In addition, business combination transactions, acquisitions, partnerships and joint ventures may require significant managerial attention, which may be diverted from NYSE Euronext's other operations. These capital, equity and managerial commitments may impair the operation of NYSE Euronext's businesses. Furthermore, any future business combination transactions or acquisitions could entail a number of additional risks, including:

•: Challenges integrating operations and maintaining key pre-transaction business relationships. There may be significant challenges in consolidating functions in a business combination, acquisition or partnership transaction, including with respect to integration of technology, organizations, procedures, policies and operations, as well as addressing differences in the business cultures and retaining key personnel. Integration may also be complex and time consuming and require substantial resources and effort, which may disrupt business operations or cause inconsistencies in standards, controls, procedures and policies. Any of the foregoing could adversely affect NYSE Euronext's relationships with market participants, employees, regulators and others with whom NYSE Euronext has business or other dealings or may impair its reputation.
•: Increased operating costs and difficulties in realizing anticipated efficiencies, synergies and cost savings. Any transaction is likely to be based in part on the projected realization of efficiencies, cost savings and other synergies. NYSE Euronext may be required to increase expenditures to manage the integration of any acquired business and it may be difficult to achieve anticipated benefits from a transaction. An increase in expenditures above NYSE Euronext's expectations or a failure to achieve anticipated efficiencies, cost savings and other synergies could adversely affect its business, financial position or results of operations.
•: Increased regulation. If NYSE Euronext enters into a transaction with a company in a jurisdiction in which NYSE or Euronext currently does not operate, some or all of its operations may become subject to laws, rules and regulatory jurisdictions to which NYSE Group and Euronext are not now subject. Although Euronext's record of cross-border integration within Europe and its open regulatory model may reduce the integration risks that NYSE Euronext may face in connection with a new business combination transaction, acquisition, partnership or joint venture in Europe, the new laws, rules and regulations that NYSE Euronext may be subject to as a result of such transactions may not be similar or consistent with the laws, rules and regulations to which NYSE Euronext is subject prior to such transaction, and there can be no assurance that the regulatory requirements across multiple jurisdictions will be harmonized or that regulatory authorities from different jurisdictions will coordinate the exercise of their respective regulatory oversight. This may increase NYSE Euronext's costs of compliance and impair its ability to conduct its business, as well as require it to undertake material restructuring of its operations, including its self-regulatory operations.
•: Exposure to unanticipated liabilities. Combining with, acquiring or partnering with another business that NYSE Euronext has not managed may result in NYSE Euronext's exposure to liabilities that it has not anticipated. This could adversely affect NYSE Euronext's business, financial position or results of operations.

In addition, following the combination, NYSE Euronext's bylaws will require acquisitions, mergers and consolidations involving more than 30% of the aggregate equity market capitalization or value of NYSE Euronext (or, under certain circumstances, transactions involving an entity whose principal place of business is outside of the United States and Europe) to be approved by two-thirds of the directors then in office. This requirement may prevent the NYSE Euronext board of directors from pursuing an acquisition, even if a majority of the board believes it to be in the best interests of the company.

The legal and regulatory environment in the United States may make it difficult for NYSE Euronext's U.S. exchanges to compete with non-U.S. exchanges for the secondary listings of non-U.S. companies and adversely affect NYSE Euronext's competitive position.

NYSE Euronext's U.S. exchanges, the NYSE and NYSE Arca, will continue to compete to obtain the listing of non-U.S. issuer securities (in addition to the listing of U.S. issuer securities). However, the legal and regulatory environment in the United States, as well as the perception of this environment, has made and may continue to make it more difficult for the NYSE and NYSE Arca to compete with non-U.S. securities exchanges for these listings and adversely affect NYSE Euronext's competitive position. For example, the Sarbanes-Oxley Act of 2002 imposes a stringent set of corporate governance, reporting and other requirements on both U.S. and non-U.S. publicly listed companies. Significant resources are necessary for issuers to come into and remain in compliance with the requirements of the Sarbanes-Oxley Act, which has had, and may continue to have, an impact on the ability of the NYSE and NYSE Arca to attract and retain listings. At the same time, international companies are increasingly seeking access to the U.S. markets through private transactions that do not require listing or trading in the U.S. public markets, such as through Rule 144A transactions. In 2000, approximately 50% of the proceeds raised by international companies in the U.S. markets were raised privately, and, from 1996 to 1999, the NYSE listed an average of approximately 48 international companies per year. In comparison, in 2005, approximately 94% of the proceeds raised by international companies in the U.S. markets were raised privately, and from 2000 to 2005, the NYSE averaged approximately 33 new listings for international companies per year. Non-U.S. issuers may choose to list with non-U.S. securities exchanges exclusively without a secondary listing in the United States because they perceive the U.S. regulatory requirements and the U.S. litigation environment as too cumbersome and costly. If the NYSE and NYSE Arca are unable to successfully attract the listing business of non-U.S. issuers, the perception of the NYSE and NYSE Arca as premier listing venues may be diminished, and NYSE Euronext's competitive position may be adversely affected or its operating results could suffer.

Following the combination, NYSE Euronext's European exchanges will not be subject to this constraint. In addition, listed companies on the Euronext exchanges are not, and will not become as a consequence of the combination, subject to the requirements of the Sarbanes-Oxley Act unless they otherwise choose to list or register their securities in the United States. However, there can be no assurances that non-U.S. issuers that do not list on the NYSE or NYSE Arca will elect to list on a Euronext exchange rather than other non-U.S. exchanges. For a description of certain arrangements that NYSE Euronext plans to implement to protect its European and U.S. exchanges from extraterritorial applications of U.S. and European law, respectively, see "The Combination—The Delaware Trust and the Dutch Foundation."

NYSE Euronext's business may be adversely affected by price competition.

The securities industry is characterized by intense price competition. The pricing model for trade execution for equity securities has changed in response to competitive market conditions. Some of NYSE Euronext's competitors have recently lowered their transaction costs and accordingly reduced the fees that they charge. In addition, NYSE Euronext will face price competition in the fees that it charges to its customers to list securities on its securities exchanges. It is likely that NYSE Euronext will experience significant pricing pressures and that some of its competitors will seek to increase their share of trading or listings by further reducing their transaction fees or listing fees, by offering larger liquidity payments or by

offering other forms of financial or other incentives. NYSE Euronext's operating results and future profitability could be adversely affected as a result of these activities. For example, NYSE Euronext could lose a substantial percentage of its share of trading or listings if it is unable to price its transactions in a competitive manner, or its profit margins could decline if it reduces its pricing in response. In addition, one or more competitors may engage in aggressive pricing strategies and significantly decrease or completely eliminate their profit margin for a period of time in order to capture a greater share of trading or listings. Some competitors, especially those outside of the United States, have high profit margins in business areas (such as clearing and settlement) in which NYSE Euronext will not engage, which may assist them in executing these strategies. This environment could lead to loss of order flow and decreased revenues, and consequently could adversely affect NYSE Euronext's operating results.

In addition, NYSE Group is engaged in an ongoing review of its pricing structures for trading fees and recently implemented a new pricing structure for some trading fees. There is risk inherent in the introduction of new pricing structures, and the implementation of a new price structure may have material adverse effects on NYSE Euronext's business, financial condition and operating results.

NYSE Group's share of trading in NYSE-listed securities has declined.

As a result of increasing competition, NYSE Group's share of trading on a matched basis in NYSE-listed securities has declined from approximately 80.6% for the three months ended June 30, 2005, to 74.8% for the three months ended June 30, 2006. If growth in NYSE Group's overall trading volume of NYSE-listed securities does not offset any significant decline in NYSE Group's share of NYSE-listed trading, or if a decline in the NYSE Group's share of trading in NYSE-listed securities makes the NYSE's market appear less liquid, then NYSE Euronext's financial condition and operating results could be adversely affected.

NYSE Euronext must keep up with emerging technological changes in order to compete effectively in a rapidly evolving and highly competitive industry.

NYSE Euronext will operate in a business environment that has undergone, and continues to experience, significant and rapid technological change. In recent years, electronic trading has grown significantly, and customer demand for increased choice of execution methods has expanded. To remain competitive, NYSE Euronext must continue to enhance and improve the responsiveness, functionality, accessibility and features of its trading platforms, software, systems and technologies. NYSE Euronext's success will depend, in part, on its ability to:

•: develop and license leading technologies useful in its businesses;
•: enhance its existing trading platforms and services;
•: respond to customer demands, technological advances and emerging industry standards and practices on a cost-effective and timely basis; and
•: continue to attract and retain highly skilled technology staff to maintain and develop its existing technology and to adapt to and manage emerging technologies.

The development and expansion of electronic trading technology entail significant technological, financial and business risks. Any failure or delay in exploiting technology, or failure to exploit technology as effectively as NYSE Euronext's competitors, could have a material adverse effect on its business, financial condition and operating results. In addition, the increased use of electronic trading on the NYSE may make it more difficult for the NYSE to differentiate its products from those of its competitors, possibly reducing one of the competitive strengths of NYSE Euronext, as the parent company of the NYSE. This may have an adverse impact on NYSE Euronext's business and, in particular, may reduce the incentive for companies to list on the NYSE. In addition, the commoditization of trade execution may result in a reduction in the number of people using the NYSE's trading floor. This may result in a decrease in the revenues realized through the use of the NYSE's trading floor.

NYSE Group and Euronext use leading technologies and currently devote substantial resources to their respective services, and NYSE Euronext intends to continue to do so after the combination. The adoption of new technologies or market practices may require NYSE Euronext to devote additional resources to modify and adapt its services. In such cases, NYSE Euronext cannot assure you that it will succeed in making these improvements to its technology infrastructure in a timely manner or at all. If NYSE Euronext is unable to anticipate or respond to the demand for new services, products and technologies on a timely and cost-effective basis or adapt to technological advancements and changing standards, it may be unable to compete effectively, which would have a material adverse effect on its business, financial condition and results of operations. Moreover, NYSE Euronext may incur substantial development, sales and marketing expenses and expend significant management effort to add new products or services to its trading platforms. Even after incurring these costs, NYSE Euronext ultimately may not realize any, or may realize only small amounts of, revenues for these new products or services. Consequently, if revenue does not increase in a timely fashion as a result of these expansion initiatives, the up-front costs associated with expansion may exceed revenue and reduce NYSE Euronext's working capital and income.

An "extraterritorial" change of law may adversely affect the businesses of NYSE Euronext and, under certain special arrangements, the rights of NYSE Euronext to control a substantial portion of its assets.

NYSE Euronext will operate securities exchanges and regulated markets in various jurisdictions and thus will be subject to a variety of laws and regulations. Although none of NYSE Euronext, NYSE Group or Euronext anticipates that there will be a material adverse application of European laws to NYSE Euronext's U.S. exchanges, or a material adverse application of U.S. laws to NYSE Euronext's European exchanges, the possibility of such an occurrence cannot be ruled out entirely. If this were to occur, and NYSE Euronext were not able to effectively mitigate the effects of such extraterritorial application, the affected exchanges of NYSE Euronext could experience a reduction in the number of listed companies or business from other market participants, or the business of NYSE Euronext could be otherwise adversely affected. In addition, in connection with obtaining regulatory approval of the combination, NYSE Euronext intends to implement certain special arrangements consisting of two standby structures, one involving a Dutch foundation and one involving a Delaware trust. The Dutch foundation will be empowered to take actions to mitigate the adverse effects of any potential changes in U.S. law that have "extraterritorial" impact on the European regulated markets of NYSE Euronext, and the Delaware trust will be empowered to take actions to ameliorate the adverse effects of any potential changes in European law that have "extraterritorial" impact on the U.S. regulated markets of NYSE Euronext. These actions include the exercise by the foundation or the trust of potentially significant control over the European or the U.S. businesses of NYSE Euronext, as the case may be. Although the foundation and the trust will be required to act in the best interest of NYSE Euronext, subject to certain exceptions, and any remedies implemented may be implemented only for so long as the effects of the material adverse application of law persist, NYSE Euronext may, as a result of the exercise of such rights, be required to transfer control over a substantial portion of its business and assets to the direction of the trust or of the foundation. Any such transfer of control could adversely affect the business and assets of NYSE Euronext. For a more detailed description of these arrangements, see "The Combination—The Delaware Trust and the Dutch Foundation."

Regulation NMS, and changes in Regulation NMS, may adversely affect the NYSE and NYSE Arca, thereby adversely affecting NYSE Euronext's operating results.

On April 6, 2005, the SEC adopted Regulation NMS, which is a set of regulations that will govern certain aspects of trading on securities market centers. Its provisions are scheduled to become operative at various points throughout 2006 and 2007. One of the principal features of Regulation NMS is the modernization of the "trade-through" or "order protection" rule. Among other things, this rule requires market centers to establish and maintain procedures to prevent "trade-throughs," which are the executions

of orders at a price inferior to the best bid or offer displayed by another market center at the time of execution. This aspect of Regulation NMS will protect and apply only to quotes available for immediate execution. The "trade-through" rule implemented by Regulation NMS is expected to increase competition between markets.

NYSE Group has begun to develop its business strategy and alter its business in consideration of the rules of Regulation NMS. NYSE Euronext will continue this implementation following the combination. There is no assurance, however, that Regulation NMS will be implemented in a timely manner or in its current form. Any delay or difficulties that arise in the implementation of Regulation NMS, as well as any amendment to Regulation NMS, could create uncertainty and adversely affect NYSE Euronext's financial condition and results of operations.

The implementation of the European Directive on Markets in Financial Instruments, or MiFID, may accelerate the development of off-exchange trading in Europe, which may harm NYSE Euronext's competitive position.

The European Commission is currently working on implementing measures for MiFID, which are due to be finalized over the course of 2006. In addition to regulated exchange trading, MiFID provides that trades may be executed on multilateral trading facilities (or MTFs) via over-the-counter (or OTC) trading, or through systematic internalization of the order flow collected by investment firms and banks. As a result, MiFID creates an opportunity for new multilateral trading facilities, over-the-counter and internalization arrangements to be developed on a pan-European basis, thereby substantially facilitating entry and increasing their attractiveness to users. In addition, investment firms will have to ensure that they obtain the "best execution" conditions for their clients, and will therefore have to direct orders to the most favorable execution venue, without any regulatory incentive to favor established regulated exchanges. Taken together, these changes to the regulatory environment may make it easier for multilateral trading facilities to establish themselves in Europe as low-cost alternatives to regulated exchanges, thereby increasing the level of competition with and between market operators. Increased competition from multilateral trading facilities could cause NYSE Euronext to lose market share or to lower its fees in order to remain competitive, either of which could lead to lower revenues and/or lower margins, harming profitability.

Regulatory changes or future court rulings may have an adverse impact on NYSE Euronext's market data fees.

NYSE Euronext anticipates that one of its significant sources of future revenue will be market data fees. Regulatory developments, however, could reduce the amount of revenue that NYSE Euronext can obtain from this source. Regulation NMS will impose significant changes on the formula used to calculate each market center's share of market data revenue. These new rules could alter behavior by market participants and reduce the share of revenue obtained by NYSE Euronext's U.S. exchanges. The formula that will be used to determine the allocation of market information revenue under Regulation NMS is highly complex, and NYSE Euronext is therefore unable at this time to forecast how the market will react to the new rules and the impact, if any, that this new allocation formula will have on NYSE Euronext's market information revenues or expenses following the implementation of Regulation NMS. In addition, the approach to fees reflected in MiFID, which explicitly authorizes market operators to sell trade information on a non-discriminatory commercial basis at a reasonable cost, could be modified by the European Commission or future European court decisions in a manner that may have an adverse impact on NYSE Euronext's market data fees.

The successful implementation and operation of the NYSE Hybrid Market^SM faces a number of significant challenges and depends on a number of factors that will be outside NYSE Euronext's control.

NYSE Group is currently working on implementing the NYSE Hybrid Market^SM, which was approved by the SEC on March 22, 2006. NYSE Euronext will continue this implementation following the

combination. The NYSE Hybrid Market^SM is intended to integrate into one platform aspects of both the physically-convened auction market and automated electronic execution. This effort is NYSE Group's response to the request from both market professionals and individual investors for greater choice and flexibility in buying and selling stocks on the NYSE. The NYSE Hybrid Market^SM is also NYSE Group's strategy for adapting to the revised "trade-through" rule adopted by the SEC on April 6, 2005 as a part of Regulation NMS, which prohibits trading through better-priced displayed quotations that are displayed by another market and immediately accessible through automatic execution. If successfully implemented, NYSE Euronext expects that the NYSE Hybrid Market^SM will change the way that securities are traded on the NYSE and will differentiate the NYSE from electronic trading venues. This initiative is being launched in phases during 2006.

In December 2005, the NYSE initiated the first phase of the NYSE Hybrid Market^SM as a pilot to test selected features and functionality among a limited number of securities approved by the SEC. The pilot terminated upon SEC approval of the NYSE Hybrid Market^SM initiative and floor-wide rollout of the first phase began. As of April 5, 2006, the first phase of the NYSE Hybrid Market^SM has been implemented in substantially all securities listed on the NYSE. To date, NYSE Hybrid Market^SM software is functioning as expected, and all implemented features are being actively exercised by trading floor professionals. However, technological, functional, or other problems with respect to NYSE Hybrid Market^SM may not come to light until additional features and functionality are introduced through subsequent pilot phases over the next several months.

Phase II of NYSE Hybrid Market^SM is targeted toward NYSE specialists and allows them to modernize their quoting and trading operations by providing an application programmed interface to connect specialist computers to NYSE computers. The NYSE has completed its rollout of Phase II software and specialist firms are in various stages of testing and implementing their software. All specialist firms are expected to be utilizing the new software by October 2006. In addition, the NYSE filed and received approval from the SEC to conduct a Phase III pilot with respect to the common stock of Lucent Technologies Inc. to provide fully automated execution capabilities. The pilot has been live since May 12, 2006 and has worked as expected by NYSE Group.

The successful implementation of the NYSE Hybrid Market^SM faces a number of significant challenges, including the difficulties of developing and implementing novel technology and the ability and willingness of specialists to build new technology platforms. In addition, as a novel technology and method of trading, there is no assurance that the NYSE Hybrid Market^SM will function as is currently anticipated, or that customers will accept and use the services that it offers. The operation of the NYSE Hybrid Market^SM also places greater demands on NYSE Regulation, and specifically on market surveillance.

Any delay or difficulties in implementing or operating the NYSE Hybrid Market^SM may have a material adverse effect on NYSE Euronext's ability to compete and its operating results, particularly if the NYSE Hybrid Market^SM is not implemented by the time that the first phase of Regulation NMS becomes operative. Currently, the first phase of Regulation NMS is scheduled to become operative on February 5, 2007. In addition, any unwillingness by its customers to accept or use the NYSE Hybrid Market^SM services may also have an adverse impact on NYSE Euronext's ability to compete and on its operating results. For a discussion of the NYSE Hybrid Market^SM, see "Information About NYSE Group—The NYSE and NYSE Arca—The NYSE Hybrid Market^SM Initiative."

NYSE Euronext intends to enter into or increase its presence in established trading markets, such as the U.S. options or futures markets or markets in countries where it does not currently compete. Demand and market acceptance for NYSE Euronext's products and services within these markets will be subject to a high degree of uncertainty and risks and may affect its growth potential.

NYSE Euronext intends to enter into or increase its presence in certain trading markets, such as the U.S. options and futures markets or markets in countries where it does not currently compete, which already possess established competitors. As a result, demand and market acceptance for NYSE Euronext's

products and services within these markets will be subject to a high degree of uncertainty and risk. If NYSE Euronext is unable to enter into or increase its presence in these markets and compete successfully, NYSE Euronext may not generate sufficient revenues from these products and services.

NYSE Euronext's growth and success may depend in part on its ability to compete with and penetrate new markets. However, it may not be successful in competing with or penetrating these markets. Attracting customers in certain countries may be subject to a number of risks, including currency exchange rate risk, difficulties in enforcing agreements or collecting receivables, longer payment cycles, compliance with the laws or regulations of foreign countries, and political and regulatory uncertainties.

The loss of key personnel may adversely affect NYSE Euronext business.

NYSE Euronext will be dependent upon the contributions of its senior management team and other key employees, as well as key staff of NYSE Regulation, for its success. With the exception of John A. Thain, NYSE Group's chief executive officer (and the designated chief executive officer of NYSE Euronext), who entered into a letter agreement with the NYSE, and certain senior managers of Euronext who have entered into employment agreements with Euronext or its subsidiaries, these individuals do not currently have agreements relating to their employment with NYSE or Euronext. Mr. Thain's letter agreement does not provide for a fixed employment term or prevent him from terminating his employment at any time. If Mr. Thain, Jean-Francois Théodore, Euronext's chief executive officer (and the designated deputy chief executive officer of NYSE Euronext), or one or more other executives or other key employees, were to cease to be employed by NYSE Euronext, it could be adversely affected. In particular, NYSE Euronext may have to incur costs to replace senior executive officers or other key employees who leave, and its ability to execute its business strategy could be impaired if NYSE Euronext is unable to replace such persons in a timely manner.

NYSE Euronext may be at greater risk from terrorism than other companies.

Given that NYSE Euronext will encompass the world's largest cash equities market and its prominence in the global securities industry, as well as the concentration of many of its properties and personnel in lower Manhattan, NYSE Euronext may be more likely than other companies to be a direct target of, or an indirect casualty of, attacks by terrorists or terrorist organizations.

It is impossible to predict the likelihood or impact of any terrorist attack on the securities industry generally or on NYSE Euronext's business. In the event of an attack or a threat of an attack, NYSE Euronext's security measures and contingency plans may be inadequate to prevent significant disruptions in its business, technology or access to the infrastructure necessary to maintain its business. For a discussion of some of NYSE Euronext's security measures and contingency plans, see "Information about NYSE Group—Security Measures and Contingency Plans." Damage to NYSE Euronext's facilities due to terrorist attacks may be significantly in excess of any amount of insurance received, or NYSE Euronext may not be able to insure against such damage at a reasonable price or at all. The threat of terrorist attacks may also negatively affect NYSE Euronext's ability to attract and retain employees. In addition, even for NYSE Euronext's electronic exchanges, terrorist attacks may cause instability or decreased trading in the securities markets, including trading on exchanges. Any of these events could have a material adverse effect on NYSE Euronext's business, financial condition and operating results.

NYSE Euronext will operate in a highly regulated industry, and may be subject to censures, fines and other legal proceedings if it fails to comply with its legal and regulatory obligations.

NYSE Euronext will operate in a highly regulated industry and be subject to extensive regulation. The securities industry is subject to extensive governmental regulation and could be subject to increased regulatory scrutiny. As a matter of public policy, these regulations are designed to safeguard the integrity of the securities and other financial markets and to protect the interests of investors in those markets. The SEC regulates the U.S. securities exchanges and has broad powers to audit, investigate and enforce

compliance with its rules and regulations and impose sanctions for non-compliance. European regulators have similar powers with respect to European exchanges in their respective countries. NYSE Euronext's ability to comply with applicable laws and rules will be largely dependent on its establishment and maintenance of appropriate systems and procedures, as well as its ability to attract and retain qualified personnel.

Both the SEC and the European regulators are vested with broad enforcement powers to censure, fine, issue cease-and-desist orders, prohibit exchanges from engaging in some of its businesses or suspend or revoke the exchange recognition, license or registration of its subsidiaries as national securities exchanges in the respective countries in which the regulators are located. In the case of actual or alleged noncompliance with regulatory requirements, NYSE Euronext could be subject to investigations and administrative or judicial proceedings that may result in substantial penalties, including revocation of a subsidiary's exchange recognition, license or registration as a securities exchange or market. Any such investigation or proceeding, whether successful or unsuccessful, would result in substantial costs and diversions of resources and might also harm NYSE Euronext's business reputation, any of which may have a material adverse effect on its business, financial condition and operating results.

In addition, there may be a conflict between the self-regulatory responsibilities of the NYSE and NYSE Arca's businesses and some of the market participants or customers of its subsidiaries. Any failure by the NYSE or NYSE Arca to diligently and fairly regulate its member organizations or to otherwise fulfill its regulatory obligations could significantly harm its reputation, prompt regulatory scrutiny and adversely affect its business.

Damage to NYSE Euronext's reputation could have a material adverse effect on its businesses.

One of NYSE Euronext's competitive strengths will be its strong reputation and brand name. NYSE Euronext's reputation could be harmed in many different ways, including by regulatory governance or technology failures. Damage to NYSE Euronext's reputation could cause some issuers not to list their securities on its exchanges, as well as reduce the trading volume on its exchanges. This, in turn, may have a material adverse effect on NYSE Euronext's business, financial condition and operating results.

NYSE Euronext will face restrictions with respect to the way in which it conducts certain operations, and may experience certain competitive disadvantages if it does not receive regulatory approval for new business initiatives or if it receives them in an untimely manner.

NYSE Euronext will operate two U.S. registered national securities exchanges—the NYSE and NYSE Arca, Inc. Pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), NYSE Euronext will be responsible for regulating the member organizations of the NYSE and NYSE Arca through the adoption and enforcement of rules governing the trading activities, business conduct and financial responsibility of its member organizations and the individuals associated with them. Changes to its rules are generally subject to the approval of the SEC, which publishes proposed rule changes for public comment. Changes to its certificate of incorporation or bylaws and changes to the certificate of incorporation, bylaws, operating agreement or rules of certain of NYSE Euronext's subsidiaries, to the extent that these changes could affect the activities of these national exchanges, must also be approved. NYSE Euronext may from time to time seek to engage in new business activities, some of which may require changes to NYSE Euronext's governing rules.

NYSE Euronext will also operate exchanges in France, Belgium, Portugal, the Netherlands and the United Kingdom. Regulators in each of these countries regulate exchanges through the adoption and enforcement of rules governing the trading activities, business conduct and financial responsibility of such exchanges and individuals associated with them. All NYSE Euronext rules and initiatives with regulatory implications must be approved by the relevant authorities in each of these countries, as well as by the coordinating bodies set up under the Euronext regulators' memoranda of understanding. Changes to NYSE Euronext's certificate of incorporation or bylaws and changes to the certificate of incorporation,

bylaws, operating agreement or rules of certain of NYSE Euronext's subsidiaries, to the extent that these changes could affect the activities of these exchanges, may also require approvals. NYSE Euronext may from time to time seek to engage in new business activities, some of which may require changes to NYSE Euronext's governing rules.

Any delay or denial of a requested approval could cause NYSE Euronext to lose business opportunities or slow the integration process in the future between its different markets. NYSE Euronext's competitive position could be significantly weakened if its competitors are able to obtain regulatory approval for new functionalities faster, or with less cost or difficulty, than NYSE Euronext is, or if approval is not required for NYSE Euronext's competitors but is required for NYSE Euronext. Competitors that are not registered exchanges are subject to less stringent regulation. In addition, as NYSE Euronext seeks to expand its product base, it could become subject to the oversight of additional regulatory bodies. For further information regarding the regulatory framework of the combined company, see "Regulation."

Regulatory developments could have a negative impact on NYSE Euronext's businesses.

Securities exchanges, particularly those in the United States, have been the subject of increasing political and public scrutiny in recent years in response to a number of developments and inquiries. In November 2004, the SEC proposed corporate governance, transparency, oversight and ownership rules for registered U.S. national securities exchanges and other self-regulatory organizations ("SROs") and issued a concept release examining the efficacy of self-regulation. The concept release also solicited public comment concerning the level of market data fees, following several years of claims from some competitors and data intermediaries that market data fees and revenues are excessive. In Europe, the European Commission is currently working on implementing measures for MiFID, which may increase the attractiveness of trading securities off-exchange. Increased trading off-exchange could cause NYSE Euronext to lose trading market share or to lower its fees in order to remain competitive.

NYSE Euronext cannot predict with certainty whether, or in what form, any regulatory changes will take place, or their impact on its business. Changes in the rules and regulations affecting SROs or European exchanges could require NYSE Euronext to change the manner in which its securities exchanges conduct their respective businesses or govern themselves. Such changes could also make it more difficult or more costly for the securities exchanges to conduct their existing businesses or to enter into new businesses.

NYSE Market and NYSE Arca will be required to allocate funds and resources to NYSE Regulation.

NYSE Market and NYSE Arca will be required to allocate significant resources to NYSE Regulation. This dedication of resources may limit NYSE Euronext's ability to reduce its expense structure and to dedicate funds and human resources in other areas. Both NYSE Market and NYSE Arca have entered into services agreements with NYSE Regulation pursuant to which they are obligated to provide funding to NYSE Regulation in exchange for regulatory services that NYSE Regulation provides to them. The obligations to fund NYSE Regulation under the agreements covering those services could negatively affect the cash available to NYSE Euronext and its ability to invest in or pursue other opportunities that may also be beneficial to NYSE Euronext stockholders. For a discussion of NYSE Euronext's proposed regulatory structure and responsibilities regarding NYSE Regulation, see "Information About NYSE Group—NYSE Regulation."

Any conflicts of interest between NYSE Euronext and NYSE Regulation may have a material adverse effect on NYSE Euronext's business.

NYSE Regulation will regulate and monitor the activities on NYSE Euronext's U.S. securities exchanges and enforce issuer and member organization compliance with applicable law and the rules of the exchanges. In a recent rule proposal, the SEC noted that there is an inherent conflict that exists within every SRO between its regulatory functions, on the one hand, and its member organizations, market

operations, listed issuers, and stockholders, on the other hand. The SEC has also expressed concern about the conflicts of interest that may exist when a for-profit entity owns an SRO. The for-profit entity's goal of maximizing stockholder value might conflict with the SRO's self-regulatory responsibilities imposed by the securities laws. For example, the for-profit entity might have an incentive to commit insufficient funds to the regulatory operations of the SRO, or use the disciplinary powers of the SRO to generate revenue for the for-profit entity by disciplining member organizations that operate or participate in competing trading systems. In addition, the regulatory responsibilities imposed by the U.S. securities laws (such as encouraging low-cost trading and competitive markets) may conflict with NYSE Euronext's profit-oriented goals as a public company. There may be more opportunities for conflicts of interest to arise when SROs regulate listed companies. Additional conflicts of interest arise where a company (such as NYSE Euronext) lists its own securities on the national securities exchange that it owns. The listing of NYSE Euronext's common stock on the NYSE could potentially create a conflict of interest between the NYSE's regulatory responsibility to vigorously oversee the listing and trading of securities on the NYSE, on the one hand, and its commercial and economic interest, on the other hand. The SRO's disciplinary power over NYSE Euronext's competitors that are U.S. registered broker-dealers may also raise questions as to potential conflicts.

NYSE Group currently maintains, and NYSE Euronext will continue to maintain, structural protections to minimize these potential conflicts of interest. For a discussion of some of these structural protections, see "Information About NYSE Group—NYSE Regulation—Structure, Organization and Governance of NYSE Regulation." These structural protections, however, may not be adequate to manage (and, in any event, will not eliminate) these potential conflicts of interest. For example, certain of the independent directors of NYSE Euronext's board of directors will serve as directors on the NYSE Regulation board of directors. In the event that NYSE Euronext fails to manage these potential conflicts of interest adequately, it could impair the effectiveness of NYSE Regulation or otherwise incur reputational damage, which could have a material adverse effect on its business, financial condition and operating results.

Specialists will be responsible for effecting certain transactions on the floor of the NYSE. Any failure by specialists to perform their function effectively or to comply with their regulatory obligations may have a material adverse effect on NYSE Euronext's business and reputation.

Specialists are an important component of the market structure within the NYSE. For example, specialists assist in providing liquidity and minimizing volatility. A deterioration in the performance of specialists, or misconduct by specialists, could damage the NYSE Euronext's reputation and reduce its ability to compete with other securities exchanges for listings and order flow. The profitability of the seven specialist units currently active on the NYSE floor has fluctuated significantly since 2002.

The increased use of technology in securities executions also is changing the business models of specialists. Any failure of the specialist to adapt their business models to this changing environment in general, and to the NYSE Hybrid Market^SM in particular, would further undermine the differentiation, and therefore the competitive position, of NYSE Market. For a discussion of certain litigation and SEC action relating to specialists, see "Information about NYSE Group—Legal Proceedings—In re NYSE Specialists Securities Litigation."

Market fluctuations and other risks beyond NYSE Euronext's control could significantly reduce demand for its services and harm its business.

NYSE Euronext's revenues and profitability are highly dependent upon the levels of activity on its exchanges, in particular the volume and value of financial instruments traded, the number and market capitalization of listed issuers, the number of new listings, the number of traders in the market and similar factors.

NYSE Euronext has no direct control over such variables. Among other things, NYSE Euronext is dependent upon the relative attractiveness of the financial instruments traded on its exchanges, and the relative attractiveness of the exchanges as a market on which to trade these financial instruments, as compared to other exchanges and trading platforms. Such variables are in turn influenced by economic, political and market conditions in the United States, Europe and elsewhere in the world that are beyond NYSE Euronext's control, including:

•: broad trends in business and finance;
•: terrorism and war;
•: concerns over inflation and the level of institutional or retail confidence;
•: changes in government monetary policy and foreign currency exchange rates;
•: the availability of short-term and long-term funding and capital;
•: the availability of alternative investment opportunities;
•: changes in the level of trading activity;
•: changes and volatility in the prices of securities;
•: changes in tax policy;
•: the level and volatility of interest rates;
•: legislative and regulatory changes, including the potential for regulatory arbitrage among U.S., European, and other markets if significant policy differences emerge among markets; and
•: unforeseen market closures or other disruptions in trading.

General economic conditions affect securities markets in a variety of ways, from determining availability of capital to influencing investor confidence. Poor economic conditions also have an impact on the process of raising capital by reducing the number or size of securities offerings or listings. The economic climate in recent years has been characterized by challenging business and economic conditions. During 2000 through early 2003, the major U.S. and European market indices experienced severe declines. The weak and uncertain economic climate, together with corporate governance and accounting concerns, contributed to a reduction in corporate transactions and generally a more difficult business environment. In addition, the United States and other countries in which NYSE Euronext hopes to offer its services have suffered acts of war or terrorism or other armed hostilities. These or similar acts have in the past increased or prolonged, and may in the future increase or prolong, negative economic conditions. Adverse changes in the economy or the outlook for the securities industry can have a negative impact on its revenues through declines in trading volume, new listings and demand for market data. Generally adverse economic conditions may also have a disproportionate effect on NYSE Euronext's business. Because its infrastructure and overhead will be based on assumptions of certain levels of market activity, significant declines in trading volumes, the number of listed companies or demand for market data may have a material adverse effect on NYSE Euronext's business, financial condition and operating results.

A significant portion of NYSE Euronext's revenues will depend, either directly or indirectly, on its transaction-based business, which, in turn, is dependent on NYSE Euronext's ability to attract and maintain order flow, both in absolute terms and relative to other market centers. If there is a decline in the trading volume on NYSE Euronext's exchanges, NYSE Euronext's revenue from transaction fees will decrease. There may also be a reduction in revenue from market data fees. If NYSE Euronext's share of total trading volume decreases relative to its competitors, NYSE Euronext may be less attractive to market participants as a source of liquidity and may lose additional trading volume and associated transaction fees and market data fees as a result. In addition, declines in NYSE Euronext's share of trading volume could adversely affect the growth, viability and importance of some of its market information products, which will constitute an important portion of NYSE Euronext's revenues.

NYSE Euronext also expects to generate a significant portion of its revenues from listing fees. Among the factors affecting companies' decisions to go public and/or list their shares on public markets are general economic conditions, industry-specific circumstances, capital market trends, mergers and acquisitions environment and regulatory requirements. The extent to which these and other factors cause companies to remain privately owned or otherwise decide not to list their shares on NYSE Euronext's exchanges may have a material adverse effect on NYSE Euronext's business, financial condition and operating results.

The financial services industry and, particularly, the securities transactions business are dynamic, uncertain and highly competitive environments. Accordingly, NYSE Euronext expects exchange consolidation and member organization consolidation to persist in the future. This environment has led to business failures and has encouraged the introduction of alternative trading venues with varying market structures and new business models. Well-capitalized competitors may seek to expand their operations in the markets where NYSE Euronext will operate. In addition, the financial services industry is subject to extensive regulation, which may change dramatically in ways that affect industry market structure. If NYSE Euronext is unable to adjust in a timely manner to structural changes within its markets, technological and financial innovation, and other competitive factors, its business will suffer.

Insufficient systems capacity or systems failure could harm NYSE Euronext's business.

NYSE Euronext's business will depend on the performance and reliability of the computer and communications systems supporting it. In particular, heavy use of NYSE Euronext's platforms and order routing systems during peak trading times or at times of unusual market volatility could cause NYSE Euronext's systems to operate slowly or even to fail for periods of time. NYSE Euronext's system capacity requirements could grow significantly in the future as the result of a variety of factors, including the implementation of the NYSE Hybrid Market^SM and NYSE Arca's anticipated expansion of its options trading volume. In addition, the use of algorithmic trading and the use of the automated price-injection model by members, and particularly by market makers, has increased significantly and may impose burdens on NYSE Euronext's network and system capacity unless steps are taken to accommodate the increase in usage.

If NYSE Euronext's systems cannot be expanded to handle increased demand, or otherwise fail to perform, NYSE Euronext could experience disruptions in service, slower response times, delays in introducing new products and services and loss of revenues. In addition, NYSE Euronext's trading activities may be negatively affected by system failures of other trading systems, as a result of which it may be required to suspend trading activity in particular stocks or, in the case of NYSE Arca, cancel previously executed trades under certain circumstances.

Failure to maintain systems or to ensure sufficient capacity may also result in a temporary disruption of NYSE Euronext's regulatory and reporting functions. These consequences, in turn, could result in lower trading volumes, financial losses, decreased customer service and satisfaction, litigation or customer claims, or regulatory sanctions.

NYSE Group and Euronext have experienced systems failures in the past. It is possible that NYSE Euronext will experience systems failures in the future, or periods of insufficient systems capacity or network bandwidth, power or telecommunications failure, acts of God or war, terrorism, human error, natural disasters, fire, power loss, sabotage, hardware or software malfunctions or defects, computer viruses, intentional acts of vandalism or similar events. Any system failure that causes an interruption in service or decreases the responsiveness of NYSE Euronext's service could impair its reputation and negatively impact its revenues. NYSE Euronext will also rely on third parties for systems support. Any interruption in these third-party services or deterioration in the performance of these services could also be disruptive to NYSE Euronext's business (and the NYSE Hybrid Market^SM, in particular) and have a material adverse effect on NYSE Euronext's business, financial condition and operating results.

NYSE Euronext's networks and those of its third-party service providers may be vulnerable to security risks, which could result in wrongful use of NYSE Euronext's information or cause interruptions in its operations that cause NYSE Euronext to lose trading volume and result in significant liabilities. NYSE Euronext will also incur significant expense to protect its systems.

NYSE Euronext expects that the secure transmission of confidential information over public networks will be a critical element of its operations. NYSE Euronext's networks and those of its third-party service providers may be vulnerable to unauthorized access, computer viruses and other security problems. Persons who circumvent security measures could wrongfully access and use NYSE Euronext's information or cause interruptions or malfunctions in NYSE Euronext's operations. Any of these events could cause NYSE Euronext to lose trading volume. NYSE Euronext will be required to expend significant further resources to protect against the threat of security breaches or to alleviate problems, including reputational harm and litigation, caused by breaches. NYSE Euronext's security measures will be costly, and may prove to be inadequate and result in system failures and delays that could cause NYSE Euronext to lose business.

As the operator of an electronic network, GL TRADE, a subsidiary of Euronext, is also subject to the risk of unauthorized infiltration of its information technology systems and those of its customers. While GL TRADE invests considerable resources to ensure the security of the GL NET network, it cannot fully eliminate the risk of unauthorized infiltration. In the event of any such infiltration, there would be a risk of disruption to the information technology systems of GL TRADE or its customers, disclosure of confidential information or falsification of customer orders. Any security breach could harm GL TRADE's reputation and/or make its customers less comfortable using its network, either of which could lead to lower revenues. Limitation of liability clauses in GL TRADE's customer agreements may prove insufficient to protect GL TRADE against liability in the event of such a breach.

NYSE Euronext's revenues from SIAC could significantly decrease if SIAC loses major customers.

The Securities Industry Automation Corporation ("SIAC"), which is two-thirds owned by the NYSE and one-third owned by AMEX, is the principal vendor of the NYSE's data processing and software development services. SIAC's non-NYSE revenues accounted for 10.3% of the NYSE's revenues, net of Section 31 fees, for the six months ended June 30, 2006. Historically, SIAC has relied on three principal customers for a majority of its revenues: (1) the NYSE, (2) AMEX and (3) the National Securities Clearing Corporation and Fixed Income Clearing Corporation. In 2005, the NYSE was the source of 58% of SIAC's revenues; AMEX was the source of 16.4% of SIAC's revenues; and the National Securities Clearing Corporation and Fixed Income Clearing Corporation were the source of 9.1% of SIAC's revenues. The National Securities Clearing Corporation and Fixed Income Clearing Corporation have entered into separate agreements with SIAC, pursuant to which the services previously provided by SIAC have been phased out. In addition, AMEX has sent a notice to SIAC indicating that it intends to materially decrease its use of SIAC's services. Negotiations with AMEX are currently being held, with a view to materially decreasing the amount of SIAC services provided to AMEX and the possible purchase by NYSE Group of the 33% of shares of SIAC held by AMEX. No definitive agreements have been reached. If

AMEX materially decreases its use of SIAC's services, as is presently anticipated, SIAC's revenues will be adversely affected. To the extent that NYSE Euronext is not able to reduce its costs associated with SIAC to offset the amount of reduction in revenue from SIAC (which NYSE Euronext may not be able to do), NYSE Euronext's profits and results of operations may be adversely affected.

Any failure by NYSE Euronext to protect its intellectual property rights, or allegations that it has infringed the intellectual property rights of others, could adversely affect its business.

NYSE Euronext owns the rights to a number of trademarks, service marks, trade names, copyrights and patents used in its businesses. To protect its intellectual property rights, NYSE Euronext will rely on a combination of trademark laws, copyright laws, patent laws, trade secret protection, confidentiality agreements and other contractual arrangements with NYSE Euronext's affiliates, customers, strategic investors and others. The protective steps taken may be inadequate to deter misappropriation of NYSE Euronext's proprietary information. NYSE Euronext may be unable to detect the unauthorized use of, or take appropriate steps to enforce, its intellectual property rights. Failure to protect its intellectual property adequately could harm NYSE Euronext's reputation and affect its ability to compete effectively. Further, defending NYSE Euronext's intellectual property rights may require significant financial and managerial resources, the expenditure of which may have a material adverse effect on NYSE Euronext's business, financial condition and operating results.

In the future, NYSE Euronext may be subject to intellectual property rights claims, which may be costly to defend, could require the payment of damages and could limit NYSE Euronext's ability to use certain technologies. Some of NYSE Group's and Euronext's competitors currently own patents and have actively been filing patent applications in recent years, some of which may relate to NYSE Group's and Euronext's trading platforms and business processes. Additionally, NYSE Euronext's competitors or other market participants may seek to do the same in the future. As a result, NYSE Group and Euronext have faced, and NYSE Euronext may face, allegations that it has infringed or otherwise violated the intellectual property rights of third parties. Any intellectual property claims, with or without merit, could be time consuming, expensive to litigate or settle and could divert management resources and attention. Successful challenges against NYSE Euronext could require it to modify or discontinue its use of technology where such use is found to infringe or violate the rights of others, or require NYSE Euronext to obtain licenses from third parties at material cost. For a discussion of litigation involving NYSE Group's intellectual property, see "Information about NYSE Group—Legal Proceedings."

NYSE Euronext will rely on Atos Euronext Market Solutions, a third party service provider that it does not control, for a number of key information technology services.

Atos Euronext Market Solutions is Euronext's preferred external supplier of key information technology and is responsible for the development of Euronext's technology and the management of its key information technology systems, including the NSC cash trading platform and the LIFFE CONNECT® futures and options electronic trading system. Euronext and Atos Origin each hold 50% of the shares of Atos Euronext Market Solutions. Control over the activities and the assets of the company rests with Atos Origin. Atos Euronext Market Solutions provides IT services to Euronext under a complex contractual framework, incorporating an umbrella services agreement and a series of interim service agreements. The umbrella services agreement will terminate in January 2012 unless a definitive and comprehensive agreement is entered into before that date. If Atos Euronext Market Solutions does not dedicate sufficient resources or provide sufficiently experienced personnel or experiences difficulties or losses, and is unable to perform the services to the required levels and meet its contractual obligations to Euronext under the IT services arrangements, the business, financial condition or results of operations of Euronext could be materially adversely affected.

Euronext also relies on intellectual property owned by Atos Euronext Market Solutions. If Atos Euronext Market Solutions does not protect its existing or future intellectual property rights, it may have

to pay third parties for rights to use their intellectual property, pay damages for infringement or misappropriation and/or be enjoined from using such intellectual property. Atos Euronext Market Solutions relies mainly on copyright legislation, patents, trademarks and protection of know-how to protect its intellectual property. Euronext cannot guarantee that any of the intellectual property rights owned by Atos Euronext Market Solutions or other intellectual property rights that third parties license to Atos Euronext Market Solutions will not be invalidated, circumvented, challenged or rendered unenforceable. Conversely, if Atos Euronext Market Solutions became involved in litigation or other proceedings as the result of alleged infringement of the rights of others, Atos Euronext Market Solutions might have to spend significant amounts of money, regardless of fault.

NYSE Euronext will rely on LCH.Clearnet and Euroclear, neither of which is controlled by Euronext, for the majority of Euronext's clearing and settlement services.

Euronext uses the services of LCH.Clearnet for clearing transactions executed on its cash markets and Euronext.liffe, and on Euroclear for settling transactions on its cash markets (except in Portugal). Although Euronext has a substantial minority shareholding in LCH.Clearnet and a small shareholding in Euroclear plc and has contractual arrangements with each of them for the provision of services, Euronext does not have any significant influence over their businesses generally, particularly with respect to their relationships with third parties. To the extent that LCH.Clearnet or Euroclear experiences serious difficulties or materially changes its business relationship with Euronext, the business of Euronext may be materially adversely affected. Additionally, because LCH.Clearnet and Euroclear each play a vital role in the functioning of Euronext's exchanges, Euronext may be affected by any difficulties that either of them experiences. If this occurs, Euronext could be harmed financially or its reputation could suffer.

GL TRADE's business could be harmed by the consolidation of financial institutions or reductions in the trading operations of its customers.

The merger of major financial institutions may lead GL TRADE's customers to reduce the number of traders and lead to further cost-cutting efforts by its customers with respect to their information systems. This environment could cause its customers to decrease the number of workstations and subscriptions they buy from GL TRADE or change their strategy by shifting to other providers or to in-house technology.

NYSE Euronext's financial condition and results of operations may be harmed if it does not successfully reduce market risks through the use of derivative financial instruments.

Since NYSE Euronext will conduct operations in both the United States and Europe, a substantial portion of its assets, liabilities, revenues and expenses will be denominated in U.S. dollars, euros and pounds sterling. Because NYSE Euronext's financial statements will be denominated in U.S. dollars, fluctuations in currency exchange rates, especially the euro/pound sterling against the U.S. dollar, could have a material impact on NYSE Euronext's reported results. NYSE Euronext will also experience other market risks, including changes in interest rates and in prices of marketable equity securities that it owns. NYSE Euronext may use derivative financial instruments to reduce certain of these risks. If NYSE Euronext's strategies to reduce market risks are not successful, its financial condition and operating results may be adversely affected.

Risks Relating to an Investment in NYSE Euronext Common Stock

There has been no prior public market for NYSE Euronext common stock.

NYSE Euronext plans to apply to list NYSE Euronext common stock on the NYSE (trading in dollars) and on Euronext Paris (Eurolist by Euronext) (trading in euros). However, an active public market for NYSE Euronext common stock may not develop or be sustained after the completion of the

combination. NYSE Euronext cannot predict the extent to which a trading market will develop or how liquid that market might become.

The market price of NYSE Euronext common stock may fluctuate. Broad market and industry factors may adversely affect the market price of NYSE Euronext common stock, regardless of its actual operating performance. Factors that could cause fluctuations in its stock price may include, among other things:

•: actual or anticipated variations in quarterly operating results;
•: changes in financial estimates by NYSE Euronext or by any securities analysts who might cover NYSE Euronext's stock;
•: conditions or trends in the industry, including regulatory changes or changes in the securities marketplace;
•: changes in the market valuations of exchanges and other trading facilities in general, or other companies operating in the securities industry;
•: announcements by NYSE Euronext or its competitors of significant acquisitions, strategic partnerships or divestitures;
•: announcements of investigations or regulatory scrutiny of NYSE Euronext's operations or lawsuits filed against it;
•: additions or departures of key personnel; and
•: sales of NYSE Euronext common stock, including sales of its common stock by its directors and officers or its strategic investors.

NYSE Euronext's share price may decline due to the large number of shares eligible for future sale.

Sales of substantial amounts of NYSE Euronext common stock, or the possibility of these sales, may adversely affect the market price of its common stock. These sales may also make it more difficult for NYSE Euronext to raise capital through the issuance of equity securities at a time and price it deems appropriate.

Upon completion of the combination, based on currently outstanding shares of NYSE Group and Euronext common stock, there will be approximately [ • ] million shares of NYSE Euronext common stock outstanding. In addition, approximately [ • ] shares of NYSE Euronext common stock will be reserved for issuance pursuant to grants to officers and employees of NYSE Euronext and certain shares of NYSE Euronext common stock may be issued to officers and employees under NYSE Euronext equity plans.

Following the combination and the post-closing reorganization, of the approximately 265.1 million shares of NYSE Euronext common stock outstanding, approximately 22.6 million shares will be subject to restrictions on transfer that are scheduled to expire on March 7, 2007, approximately 33.9 million shares will be subject to restrictions on transfer that are scheduled to expire on March 7, 2008, and approximately 41.8 million shares will be subject to restrictions on transfer that are scheduled to expire on March 7, 2009. These restrictions are a continuation of the restrictions placed on shares of NYSE Group common stock issued to former NYSE members and certain Archipelago stockholders in the merger between the NYSE and Archipelago, and will apply solely to the shares of NYSE Euronext common stock issued in the merger to holders of restricted NYSE Group common stock immediately before the merger. NYSE Euronext's board of directors may, from time to time in its sole discretion, release any of these transfer restrictions from any number of these restricted shares, on terms and conditions and in ratios and numbers to be fixed by the board of directors in its sole discretion. For a description of the transfer restrictions see "Description of NYSE Euronext Capital Stock—Transfer Restrictions on Certain Shares of NYSE Euronext Common Stock."

Removal of the transfer restrictions may lead to significant numbers of shares of NYSE Euronext common stock becoming available for sale, which may adversely affect the then-prevailing market price of NYSE Euronext common stock.

Provisions of NYSE Euronext's organizational documents and applicable law may delay or deter a change of control of NYSE Euronext.

Following the combination, NYSE Euronext's organizational documents will contain provisions that may have the effect of discouraging, delaying or preventing a change of control of, or unsolicited acquisition proposals for, NYSE Euronext that a stockholder might consider favorable. These include provisions:

•: vesting the NYSE Euronext board of directors with sole power to set the number of directors;
•: limiting the persons that may call special stockholders' meetings;
•: limiting stockholder action by written consent;
•: requiring supermajority stockholder approval or supermajority board approval with respect to certain amendments to the NYSE Euronext bylaws; and
•: requiring supermajority stockholder approval with respect to certain amendments to the NYSE Euronext certificate of incorporation.

In addition, its organizational documents will include provisions that:

•: restrict any person (either alone or together with its related persons) from voting or causing the voting of shares of stock representing more than 10% of NYSE Euronext's outstanding voting capital stock (including as a result of any agreement by any other persons not to vote shares of stock); and
•: restrict any person (either alone or together with its related persons) from beneficially owning shares of stock representing more than 20% of the outstanding shares of any class or series of NYSE Euronext's capital stock.

For a more detailed description of these provisions, see "Description of NYSE Euronext Capital Stock," as well as the forms of NYSE Euronext certificate of incorporation and bylaws that will be in effect after the completion of the combination, which forms are included as Exhibits 3.1 and 3.2, respectively, to the registration statement of which this document forms a part.

Furthermore, the NYSE Euronext board of directors has the authority to issue shares of preferred stock in one or more series and to fix the rights and preferences of these shares without stockholder approval. Any series of NYSE Euronext preferred stock is likely to be senior to the NYSE Euronext common stock with respect to dividends, liquidation rights and, possibly, voting rights. The ability of the NYSE Euronext board of directors to issue preferred stock also could have the effect of discouraging unsolicited acquisition proposals, thus adversely affecting the market price of the common stock.

In addition, Delaware law makes it difficult for stockholders that recently have acquired a large interest in a corporation to cause the merger or acquisition of the corporation against the directors' wishes. Under Section 203 of the Delaware General Corporation Law, a Delaware corporation may not engage in any merger or other business combination with an interested stockholder for a period of three years following the date that the stockholder became an interested stockholder except in limited circumstances, including by approval of the corporation's board of directors. See "Comparison of Shareholder Rights Prior to and After the Combination."

Section 26a of the Dutch Act on the Supervision of the Securities Trade 1995 (Wet toezicht effectenverkeer 1995) requires a declaration of no objection of the Dutch Minister of Finance of any

acquisition or holding of a direct or indirect interest of more than 10% of the outstanding capital or voting rights in Euronext. Such declaration should be granted unless the acquisition harms or could harm the proper functioning of the market or investor interests or the acquisition hinders or could hinder the proper monitoring of compliance of Euronext with applicable laws and regulations. Similar restrictions also apply to indirect ownership of certain qualifying interests or percentages of voting rights in certain regulated subsidiaries of Euronext. (See "Regulation—European Regulation.")

Additionally, a change of control of NYSE Euronext or its subsidiaries may be conditioned upon, among things, governmental authorizations, consents, orders and approvals of certain European regulatory authorities and the SEC, which may impose conditions on, or require divestitures or other changes relating to, the divisions, operations or assets of NYSE Euronext. For example, the SEC and the European regulators may require changes to the structure, certificate of incorporation or bylaws of NYSE Euronext and its subsidiaries as a precondition to their approval of any change of control of NYSE Euronext or its subsidiaries.

If NYSE Euronext is unable to favorably assess the effectiveness of its internal controls over financial reporting, or if its Independent Registered Public Accounting Firm is unable to provide an unqualified attestation report on NYSE Euronext's assessment, the stock price of NYSE Euronext could be adversely affected.

Under current SEC rules, assuming the combination is completed in 2007, pursuant to Sections 302 and 404 of the Sarbanes-Oxley Act of 2002, in connection with NYSE Euronext annual report on Form 10-K for the fiscal year ending December 31, 2007, the management of NYSE Euronext will be required to certify to and report on, and NYSE Euronext's Independent Registered Public Accounting Firm will be required to attest to, the effectiveness of NYSE Euronext's internal controls over financial reporting with respect to the operations of NYSE Group as of December 31, 2007. NYSE Euronext and its Independent Registered Public Accounting Firm will have an additional year to attest to the effectiveness of NYSE Euronext's internal controls over financial reporting with respect to the operations of Euronext. The rules governing the standards that must be met for management to assess NYSE Euronext's internal controls over financial reporting are new and complex, and require significant documentation, testing and possible remediation. The continuing effort to comply with regulatory requirements relating to internal controls will likely cause NYSE Euronext to incur increased expenses and diversion of management's time and other internal resources, in particular in respect of Euronext and its subsidiaries, which have not previously been subject to Rule 404 requirements. NYSE Euronext also may encounter problems or delays in completing the implementation of any changes necessary to make a favorable assessment of our internal controls over financial reporting. In addition, in connection with the attestation process by NYSE Euronext's Independent Registered Public Accounting Firm, NYSE Euronext may encounter problems or delays in completing the implementation of any requested improvements or receiving a favorable attestation. If NYSE Euronext cannot favorably assess the effectiveness of its internal controls over financial reporting, or if NYSE Euronext's Independent Registered Public Accounting Firm is unable to provide an unqualified attestation report on NYSE Euronext's assessment, investor confidence and the stock price of NYSE Euronext's common stock could be adversely affected.

THE SPECIAL MEETING OF NYSE GROUP STOCKHOLDERS

Time, Place and Purpose of the NYSE Group Special Meeting

The special meeting of NYSE Group stockholders is scheduled to be held on [ • ] at [ • ], local time, at [ • ]. The purpose of the NYSE Group special meeting is:

•: to consider and vote on the proposal to approve and adopt the combination agreement and the transactions contemplated by the combination agreement; and
•: to transact any other business as may properly come before the NYSE Group special meeting or any adjournment or postponement of the NYSE Group special meeting.

The NYSE Group board of directors recommends that you vote FOR the proposal to approve and adopt the combination agreement and the transactions contemplated by the combination agreement. For the reasons for this recommendation, see "The Combination—NYSE Group's Reasons for the Combination."

Who Can Vote at the NYSE Group Special Meeting

Only holders of record of NYSE Group common stock at the close of business on [ • ], the record date, are entitled to notice of, and to vote at, the NYSE Group special meeting. As of [ • ], there were [ • ] shares of NYSE Group common stock issued and outstanding, of which [ • ] shares were entitled to vote at the NYSE Group special meeting, after taking into account the voting limitations described under "The Special Meeting of NYSE Group Stockholders—Voting Limitations." These shares were held by approximately [ • ] holders of record. Each share of NYSE Group common stock is entitled to one vote at the NYSE Group special meeting. Shares that are held in NYSE Group's treasury are not entitled to vote at the NYSE Group special meeting. See "The Special Meeting of NYSE Group Stockholders—Voting Limitations" below for a discussion of certain voting limitations for NYSE Group stockholders.

Votes Required

The approval and adoption of the combination agreement requires the affirmative vote of the holders of a majority of the shares of NYSE Group common stock outstanding and entitled to vote at the NYSE Group special meeting as of the record date, voting as a single class, either in person or by proxy.

The holders of record of a majority of the total number of outstanding shares of NYSE Group common stock entitled to vote, represented either in person or by proxy, will constitute a quorum at the NYSE Group special meeting.

Voting Limitations

The NYSE Group certificate of incorporation places certain ownership and voting limits on the holders of NYSE Group capital stock. In particular, under the NYSE Group certificate of incorporation:

•: no person, either alone or together with its related persons (as defined below), may beneficially own shares of NYSE Group stock representing in the aggregate more than 20% of the total number of votes entitled to be cast on any matter; and
•: no person, either alone or together with its related persons, is entitled to vote or cause the voting of shares of NYSE Group stock beneficially owned by that person or its related persons to the extent that those shares would represent in the aggregate more than 10% of the total number of votes entitled to be cast on any matter, and no person, either alone or together with its related persons, is entitled to vote more than 10% of the total number of votes entitled to be cast on any matter by

virtue of agreements entered into by that person or those related persons with other persons not to vote shares of NYSE Group's outstanding capital stock.

The NYSE Group board of directors may waive the provisions regarding ownership and voting limits by a resolution expressly permitting this ownership or voting (which resolution must be filed with, and approved by, the SEC prior to being effective), subject to a determination of the NYSE Group board of directors that:

•: the acquisition of beneficial ownership in excess of the ownership limits or exercise of voting rights in excess of the voting limits will not impair the ability of NYSE Group's U.S. self-regulatory subsidiaries (which include the NYSE, NYSE Market, Inc., NYSE Regulation, Inc., NYSE Arca, Inc. and NYSE Arca Equities, Inc.) to discharge their respective responsibilities under the Exchange Act and the rules and regulations under the Exchange Act and is otherwise in the best interests of NYSE Group and its stockholders and regulated subsidiaries;
•: the acquisition of beneficial ownership in excess of the ownership limits or exercise of voting rights in excess of the voting limits will not impair the SEC's ability to enforce the Exchange Act;
•: neither the person obtaining the waiver nor any of its related persons is subject to any statutory disqualification (as defined in Section 3(a)(39) of the Exchange Act) if such person is seeking to obtain a waiver above the 20% ownership or voting level;
•: for so long as NYSE Group directly or indirectly controls NYSE Arca, Inc., NYSE Arca Equities, Inc. or any facility of NYSE Arca, Inc., neither the person obtaining the waiver nor any of its related persons is an Equity Trading Permit ("ETP") Holder, an Option Trading Permit ("OTP") Holder or an OTP Firm (as such terms are defined in the rules of NYSE Arca, Inc. as such rules may be in effect from time to time) if such person is seeking to obtain a waiver above the 20% ownership or voting level; and
•: for so long as NYSE Group directly or indirectly controls the NYSE or NYSE Market, Inc., neither the person obtaining the waiver nor any of its related persons is a member or member organization of the NYSE if such person is seeking to obtain a waiver above the 20% ownership or voting level.

In making these determinations, the NYSE Group board of directors may impose conditions and restrictions on the relevant stockholder or its related persons that it deems necessary, appropriate or desirable in furtherance of the objectives of the Exchange Act and the governance of NYSE Group. The NYSE Group board of directors has adopted a resolution approving NYSE Euronext's level of ownership and voting of NYSE Group common stock as a result of the combination and the post-closing reorganization. This resolution has not yet been submitted to the SEC. No other such exception has been applied for, granted or become effective. The NYSE Group certificate of incorporation requires NYSE Group to disregard any votes cast in excess of the voting limitations.

The voting limitations do not apply to a solicitation of a revocable proxy by NYSE Group or by the directors or officers of NYSE Group on behalf of NYSE Group or to a solicitation of a revocable proxy by a stockholder in accordance with Regulation 14A under the Exchange Act. This exception, however, does not apply to certain solicitations by a stockholder pursuant to Rule 14a-2(b)(2) under the Exchange Act, which permits a solicitation made otherwise than on behalf of NYSE Group where the total number of persons solicited is not more than ten.

The NYSE Group certificate of incorporation also provides that the NYSE Group board of directors has the right to require any person (and its related persons) that the NYSE Group board of directors reasonably believes to be subject to the voting or ownership restrictions summarized above, and any stockholder, including related persons, that at any time beneficially owns 5% or more of the then outstanding capital stock of NYSE Group entitled to vote on any matter (and has not reported that ownership to NYSE Group), to provide to NYSE Group complete information as to all shares of the

NYSE Group capital stock that such stockholder beneficially owns, as well as any other information relating to the applicability to such stockholder of the voting and ownership requirements outlined above as may reasonably be requested.

If you are a related person with respect to another holder of NYSE Group common stock where either: (i) you (either alone or with your related person) may vote shares of NYSE Group common stock representing more than 10% of the then outstanding votes entitled to vote at the special meeting of NYSE Group stockholders, or (ii) you have entered into an agreement not to vote shares of NYSE Group common stock, the effect of which agreement would be to enable any person, either alone or with its related persons, to vote or cause the voting of shares of the NYSE Group common stock that represent in the aggregate more than 10% of the then outstanding votes entitled to be cast at the special meeting of NYSE Group stockholders, then please so notify NYSE Group by either including that information (including each related person's complete name) on your proxy card or by contacting the corporate secretary of NYSE Group at NYSE Group, Inc., 11 Wall Street, New York, NY 10005.

For the purposes of the NYSE Group certificate of incorporation including the voting and ownership limitations described above, "related persons" shall mean with respect to any person:

•: any "affiliate" (as such term is defined in Rule 12b-2 under the Exchange Act) of such person;
•: any other person(s) with which such first person has any agreement, arrangement or understanding (whether or not in writing) to act together for the purpose of acquiring, voting, holding or disposing of shares of the stock of NYSE Group;
•: in the case of a person that is a company, corporation or similar entity, any executive officer (as defined under Rule 3b-7 under the Exchange Act) or director of such person and, in the case of a person that is a partnership or a limited liability company, any general partner, managing member or manager of such person, as applicable;
•: in the case of a person that is a "member organization" (as defined in the rules of the NYSE, as such rules may be in effect from time to time), any "member" (as defined in the rules of the NYSE, as such rules may be in effect from time to time) that is associated with such person (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act);
•: in the case of a person that is an OTP Firm (as defined in the rules of NYSE Arca, Inc., as such rules may be in effect from time to time), any OTP Holder (as defined in the rules of NYSE Arca, Inc., as such rules may be in effect from time to time) that is associated with such person (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act);
•: in the case of a person that is a natural person, any relative or spouse of such natural person, or any relative of such spouse who has the same home as such natural person or who is a director or officer of NYSE Group or any of its parents or subsidiaries;
•: in the case of a person that is an executive officer (as defined under Rule 3b-7 under the Exchange Act), or a director of a company, corporation or similar entity, such company, corporation or entity, as applicable;
•: in the case of a person that is a general partner, managing member or manager of a partnership or limited liability company, such partnership or limited liability company, as applicable;
•: in the case of a person that is a "member" (as defined in the rules of the NYSE, as such rules may be in effect from time to time), the "member organization" (as defined in the rules of the NYSE, as such rules may be in effect from time to time) with which such person is associated (as determined

using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act); and

•: in the case of a person that is an OTP Holder, the OTP Firm with which such person is associated (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act).

Adjournments

If no quorum of NYSE Group stockholders entitled to vote is present in person or by proxy at the NYSE Group special meeting, the NYSE Group special meeting may be adjourned from time to time until a quorum is present or represented. In addition, adjournments of the NYSE Group special meeting may be made for the purpose of soliciting additional proxies in favor of the proposal. An adjournment of the NYSE Group special meeting may be made from time to time for up to 30 days by the chairman of the special meeting, without further notice (unless a new record date is fixed for the adjourned NYSE Group special meeting) other than by an announcement made at the NYSE Group special meeting. However, no proxy that is voted against a proposal described in this document will be voted in favor of adjournment of the NYSE Group special meeting for the purpose of soliciting additional proxies.

Manner of Voting

If you are a NYSE Group stockholder and you hold your NYSE Group common stock in your own name, you may submit your vote for or against the proposal submitted at the NYSE Group special meeting in person or by proxy. You may vote by proxy in any of the following ways:

•: by using the enclosed proxy card and mailing a completed and signed proxy card to the address listed on the proxy card using the provided self-addressed stamped envelope;
•: by telephone using the toll-free number shown on the enclosed proxy card; or
•: by visiting the website noted on the enclosed proxy card and voting through the Internet by no later than [ • ].

Information and applicable deadlines for using the proxy card, or voting by telephone or through the Internet, are set forth in the enclosed proxy card instructions.

If your shares of NYSE Group common stock are registered in the name of a broker, bank or other nominee (which is also known as being held in "street name"), that broker, bank or other nominee has enclosed or will provide a voting instruction card for the NYSE Group stockholder to direct the broker, bank or other nominee how to vote its shares. NYSE Group stockholders who hold shares in "street name" must return their instructions to their broker, bank or other nominee on how to vote their shares. If a NYSE Group stockholder that holds shares in "street name" desires to attend the NYSE Group special meeting, the NYSE Group stockholder should bring a letter from its broker, bank or other nominee identifying the NYSE Group stockholder as the beneficial owner of such shares, confirming that such shares have not otherwise been voted and will not be voted via proxy, and authorizing the NYSE Group stockholder to vote the shares or specifying how such shares had been voted.

All shares of NYSE Group common stock represented by properly executed proxies or voting instructions (including those given by phone or through the Internet) received in time for the NYSE Group special meeting will, unless revoked, be voted in accordance with the instructions indicated on those proxies or voting instructions. If no instructions are indicated on a properly executed proxy card, the shares will be voted in accordance with the recommendation of the NYSE Group board of directors and, therefore, FOR the approval and adoption of the combination agreement.

If you are a NYSE Group stockholder and your proxy indicates instructions for some, but not all, of the proposals, your votes will be cast as indicated on the specified proposals and as described in the preceding sentence for any proposal for which no instructions are indicated.

If you return a properly executed proxy card or voting instruction card and have indicated that you have abstained from voting on a proposal, your shares of NYSE Group common stock represented by the proxy will be considered present at the NYSE Group special meeting for purposes of determining a quorum, but will have the same effect as a vote against the proposal. NYSE Group urges you to mark each applicable box on the proxy card or voting instruction card to indicate how to vote your shares of NYSE Group common stock.

You may revoke your proxy at any time before it is voted by:

•: submitting a written revocation dated after the date of the proxy that is being revoked to the [ • ],[ • ];
•: submitting a later-dated proxy by mail, fax, telephone or through the Internet; or
•: attending the NYSE Group special meeting and voting by paper ballot in person.

Attendance at the NYSE Group special meeting will not, in and of itself, constitute revocation of a previously granted proxy. If the NYSE Group special meeting is adjourned or postponed, it will not affect the ability of NYSE Group stockholders to exercise their voting rights or to revoke any previously granted proxy using the methods described above.

Broker Non-Votes

If you are a NYSE Group stockholder and your NYSE Group shares are held in an account at a broker, bank or other nominee and you wish to vote, you must instruct the broker, bank or other nominee on how to vote your shares. If an executed proxy card returned by a broker, bank or other nominee holding NYSE Group shares on your behalf indicates that the broker, bank or other nominee does not have discretionary authority to vote on a particular matter, the shares will be considered present at the meeting for purposes of determining the presence of a quorum, but will have the same effect as a vote against the combination agreement. This is called a broker non-vote. Your broker, bank or other nominee will vote your shares over which it does not have discretionary authority only if you provide instructions on how to vote by following the instructions provided to you by your broker, bank or other nominee. If you own shares of NYSE Group common stock through a broker, bank or other nominee and attend the NYSE Group special meeting, you should bring a letter from your broker, bank or other nominee identifying you as the beneficial owners of the shares of NYSE Group common stock and authorizing you to vote.

Solicitation of Proxies

NYSE Group will incur expenses in connection with the printing and mailing of this document. To assist in the solicitation of proxies, NYSE Group has retained [ • ] for a fee of approximately [ • ] plus reimbursement of out-of-pocket expenses. NYSE Group and its proxy solicitor also will request banks, brokers and other intermediaries holding shares of NYSE Group common stock beneficially owned by others to send this document to, and obtain proxies from, the beneficial owners and will, if requested, reimburse the record holders for their reasonable out-of-pocket expenses in so doing. Solicitation of proxies by mail may be supplemented by telephone and other electronic means, advertisements and personal solicitation by the directors, officers or employees of the NYSE and NYSE Group. No additional compensation will be paid to NYSE Group directors, officers or employees for solicitation.

THE COMBINATION

This section of the document describes material aspects of the proposed combination. This summary may not contain all of the information that is important to you. You should carefully read this entire document, including the full text of the combination agreement, which is attached as Annex A, and the other documents referred to for a more complete understanding of the combination.

General

NYSE Group and Euronext have entered into an agreement providing for a combination of their businesses under a new holding company named NYSE Euronext. Euronext's business will be brought under the new holding company through an exchange offer, and NYSE Group's business will be brought under the new holding company through a merger.

In the exchange offer, Euronext shareholders will be offered the right to exchange each of their Euronext shares for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. Instead of receiving this standard offer consideration, Euronext shareholders will have an opportunity to make either a cash election to receive all cash for their Euronext shares, or a stock election to receive all stock for their Euronext shares. These elections, however, are subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all tendering Euronext shareholders received the standard offer consideration.

The merger will occur as soon as practicable following completion of the exchange offer. In the merger, NYSE Group stockholders will have the right to receive one share of NYSE Euronext common stock for each of their shares of NYSE Group common stock. Holders of NYSE Group stock options to acquire NYSE Group common stock will receive options to acquire an equivalent number of shares of NYSE Euronext common stock, and holders of NYSE Group restricted stock units will receive an equivalent number of NYSE Euronext restricted stock units. Shares of NYSE Euronext common stock that are issued to NYSE Group stockholders in the merger will be subject to the same transfer restrictions, if any, that the shares of NYSE Group common stock were subject to prior to the merger.

Following the successful completion of the exchange offer and simultaneously with or as soon as possible after the completion of the merger, NYSE Euronext intends to effectuate a post-closing reorganization of Euronext that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. In the post-closing reorganization, Euronext shareholders who did not exchange their Euronext shares in the exchange offer will be provided with the same consideration that such shareholders would have received had such shareholders tendered their Euronext shares in the exchange offer and not made the cash election or stock election. (See "The Combination Agreement—The Exchange Offer—Mix and Match Election" and "The Combination Agreement—Post-Closing Reorganization). Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer. See "The Combination—Material Dutch Tax Consequences—Post-Closing Reorganization Effectuated other than Pursuant to the Compulsory Acquisition Procedure—Dividend Withholding Tax." This document refers to this reorganization as the "post-closing reorganization." In the post-closing reorganization, each Euronext share will be exchanged for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. However, in the event that 95% or more of the issued and outstanding share capital of Euronext is tendered in the exchange offer, NYSE Euronext may at its option effectuate the post-closing reorganization by initiating a compulsory acquisition procedure (uitkoopregeling) in

accordance with section 2:92a of the Dutch Civil Code. In such circumstances, the price to be paid for such shares would be paid in cash only, in an amount determined by the Enterprise Chamber of the Amsterdam Court of Appeals, which may be in an amount that is substantially more or less than the value of the consideration that Euronext shareholders received in the exchange offer. NYSE Euronext has the right to change aspects of the post-closing reorganization steps, subject to Euronext's prior consent, which may be withheld if its supervisory and managing boards determine in good faith that it needs to do so in order to comply with its fiduciary duties under applicable law. For further details regarding the post-closing reorganization, see "The Combination Agreement—Post- Closing Reorganization."

Following the successful completion of the exchange offer, Euronext stock options or other Euronext stock-based awards, whether vested or unvested, will be converted into a NYSE Euronext stock option or a NYSE Euronext stock-based award, respectively, on the same terms and conditions as were applicable under such Euronext stock option and Euronext stock-based award prior to the post-closing reorganization (or such other arrangement to which NYSE Group and Euronext shall mutually agree prior to the filing of the exchange offer with the AMF). Such conversion will occur at the time of the merger or to the extent not feasible at such date for some or all holders in some or all jurisdictions (for tax reasons or otherwise), promptly thereafter and in any event no later than the completion of the post-closing reorganization. The number of shares of NYSE Euronext common stock subject to each such NYSE Euronext stock option or NYSE Euronext stock-based award shall be the number of Euronext shares subject to each such Euronext stock option or Euronext stock-based award multiplied by the stock election amount (which is the amount of stock a Euronext shareholder who made the stock election in the offer would have received), rounded, if necessary, to the nearest whole share of NYSE Euronext common stock. Such NYSE Euronext stock option shall have an exercise price per share (rounded to the nearest one-hundredth of a cent) equal to the per share exercise price specified in such Euronext stock option divided by the stock election amount.

In certain circumstances, if the conversion of any of the Euronext stock options or Euronext stock-based awards would cause holders who are French residents for tax purposes to incur incrementally more taxes and/or social security charges than would be the case had they otherwise complied with certain requirements for favorable tax treatment under French law (including by holding the Euronext stock options and Euronext stock-based awards for requisite holding and vesting periods), NYSE Euronext will make specific arrangements for such holders in order to avoid, or reimburse French holders for, such incremental tax and social security liability. For a description of these arrangements, see "The Combination Agreement—Treatment of Euronext Stock Options and Stock-Based Awards Following the Exchange Offer." Certain steps may be taken to effectuate the post-closing reorganization.

The aggregate number of shares of NYSE Euronext common stock issued to the NYSE Group stockholders and Euronext shareholders in the combination will represent approximately 59% and 41%, respectively, of the NYSE Euronext common stock outstanding immediately after the combination assuming that any post-closing reorganization has been successfully completed.

The rights of holders of NYSE Euronext common stock will be different from the rights of NYSE Group stockholders and Euronext shareholders because the NYSE Euronext certificate of incorporation and bylaws in effect immediately after the combination will be different from the governing documents of NYSE Group and Euronext, and, in the case of Euronext, will be governed by Delaware law instead of Dutch law. See "Comparison of Shareholder Rights Prior to and After the Combination" for a description of the material differences.

Background of the Combination

The NYSE Group board of directors and the Euronext supervisory and managing boards continually review their respective companies' results of operations and competitive positions in the industries in which they operate, as well as their strategic alternatives. In connection with these reviews, each of NYSE Group and Euronext from time to time has evaluated potential transactions that would further its strategic objectives.

As part of this continuous review, Euronext has since 2004 engaged in discussions regarding possible merger and acquisition transactions with a number of companies in its industry. Following the announcement by Deutsche Börse on December 13, 2004 of a potential cash offer to acquire the London Stock Exchange plc, Euronext entered into discussions with the London Stock Exchange. On December 20, 2004, Euronext announced that it was also considering making a cash offer to acquire the London Stock Exchange and was seeking a recommendation from the London Stock Exchange board. After further meetings with the London Stock Exchange, Euronext publicly reconfirmed its interest in a possible cash offer on January 27, 2005, submitted a filing relating to the possible offer with the U.K. Office of Fair Trading on January 28, 2005 and published key aspects of its potential proposal to acquire the London Stock Exchange on February 9, 2005. On March 29, 2005, the U.K. Office of Fair Trading referred the potential offers of Euronext and Deutsche Börse to the U.K. Competition Commission for investigation and report. On November 1, 2005, the U.K. Competition Commission issued its report, clearing both transactions subject to agreement of remedy undertakings that, in the case of Euronext, were agreed and announced on March 14, 2006. Discussions between Euronext and the London Stock Exchange took place during and following this antitrust review process. These discussions, however, ceased after The Nasdaq Stock Market, Inc. ("Nasdaq") announced on April 11, 2006 that it had acquired a substantial shareholding (approximately 15%) in the London Stock Exchange. On May 3, 2006, Euronext announced that, in light of this development, it was no longer in discussions with the London Stock Exchange regarding a possible offer for the company.

Euronext also engaged in discussions with Deutsche Börse regarding a possible business combination, initially in mid-2004 and more fully in late 2005. During the latter series of discussions, however, fundamental differences in approach became apparent between the parties in terms of, among other things, business model and corporate governance.

During the same period of late 2005 and the early part of 2006, Euronext also engaged in discussions with a major U.S. exchange, following that exchange's expression of interest in a possible business combination. The discussions between the parties were focused primarily on possible synergies resulting from a combination, with preliminary discussions taking place in late April 2006 on possible transaction structures. The discussions did not lead to any concrete proposals for a combination between the two companies.

NYSE Group also from time to time considers its strategic alternatives. After the announcement of NYSE Group's acquisition of Archipelago, NYSE Group had begun to focus on opportunities that would provide it with the ability to enhance its competitive position globally, strengthen and diversify its business and revenue streams, enter new markets and advance its technology. In early January 2006, John A. Thain, chief executive officer of NYSE Group, and Jean-Francois Théodore, chief executive officer of Euronext, met in New York, at which meeting they discussed the possibility of a business combination between NYSE Group and Euronext. Mr. Thain and Mr. Théodore considered how such a combination would be beneficial to both companies and their respective constituents: the combination would create the first truly global exchange with broad international reach (encompassing seven exchanges in six countries), diverse product offerings (trading equities, fixed income and derivatives in both U.S. dollars and euros) and leading technology. Mr. Thain and Mr. Théodore agreed that the possibility of a combination merited additional review and discussions.

In February 2006, NYSE Group and Euronext management representatives were present at a meeting of the World Federation of Exchanges in Milan, Italy. At that meeting, members of management of NYSE Group and Euronext continued discussions regarding a possible combination between the two companies and began exploring the structural and technical aspects of a combination.

In light of Euronext's contacts with various parties regarding business combinations and related press speculation, Euronext issued a press release on April 3, 2006 that set out the key criteria that it would take into consideration in assessing possible business combinations. These were stated to include, in addition to value creation for shareholders and protecting the interests of its other stakeholders, the quantum and

deliverability of synergies, the preservation of key markets and businesses, proposed regulatory and governance structures, implementation risk and the value proposition to its shareholders, users and issuers.

During the course of April 2006, a further series of meetings were held between representatives of Euronext and Deutsche Börse and their respective legal and financial advisors to discuss in detail various aspects of a potential combination such as the business model of the combined company, synergies of the combination, transaction structure, competition law aspects and governance. These meetings did not result in an agreement between the parties.

On April 12, 2006, NYSE Group and Euronext entered into a confidentiality agreement to facilitate exchanges of due diligence materials between the managements of both companies. During the remainder of that month, NYSE Group management and Euronext management had periodic discussions regarding possible transaction structures and consideration, as well as key social and governance issues presented by a combination between the two companies. In this regard, NYSE Group consulted with its financial advisor, Citigroup, and its legal advisor, Wachtell, Lipton, Rosen & Katz ("Wachtell Lipton"), and Euronext consulted with its financial advisors, Morgan Stanley and ABN AMRO, and its legal advisors, Bredin Prat, Cleary Gottlieb Steen & Hamilton LLP ("Cleary Gottlieb") and Stibbe. However, during this time, no formal proposals were made, and no agreement was reached.

On April 29, 2006, a joint meeting of the Euronext managing board and the Euronext supervisory board took place. At the meeting, the current status of the discussions with the London Stock Exchange, Deutsche Börse, NYSE Group and another major U.S. exchange were reviewed on the basis of presentations made by representatives of Euronext's financial advisors, Morgan Stanley and ABN AMRO, including comparisons of the financial and other terms of the respective potential transactions as known at that time, except for those relating to the London Stock Exchange, for which the boards concluded that there was no longer a basis for continued discussions given the acquisition by Nasdaq of a substantial stake in the London Stock Exchange. The Euronext boards extensively discussed the various elements of the potential transactions in terms of financial comparison, transaction rationale, synergies, proposed transaction structure (on the basis of a presentation by Euronext's legal advisor Stibbe), governance structure and management organization, business location, IT aspects, regulatory regime and competition issues and compared the potential transactions in terms of value creation, execution risk and perpetuation of the Euronext model. Without drawing any final conclusions, the Euronext boards formed the view that, based on the status of the discussions and negotiations at that time, a potential combination with NYSE Group seemed to be the preferred option, and the supervisory board requested the managing board to continue discussions with NYSE Group, with a special focus on regulatory aspects of the proposed combination and on the enshrinement of corporate governance principles that would ensure a balance between U.S. and European representation on the board of directors of the combined entity.

On May 11, 2006, the NYSE Group board of directors met to discuss various strategic alternatives that might be available to it, including the proposed business combination with Euronext. NYSE Group management updated the board on management's preliminary discussions with Euronext and outlined the potential benefits and risks associated with the combination as compared to the company's other alternatives. Citigroup also reviewed with the board the anticipated financial aspects of the various strategic alternatives, and Wachtell Lipton outlined legal and regulatory considerations in reviewing these alternatives. The board authorized NYSE Group management to continue its discussions with Euronext regarding a potential business combination transaction.

From mid-May to June 1, 2006, NYSE Group and Euronext and their respective legal and financial advisors continued discussions regarding the terms of the transaction, including transaction structures and consideration, as well as the social and governance aspects of a combination.

On May 15, 2006, NYSE Group, through Wachtell Lipton, delivered a draft combination agreement to Euronext, through Cleary Gottlieb, for review and negotiation. Following the delivery of the draft combination agreement, the parties and their respective counsel reviewed, negotiated and revised the draft combination agreement.

Concurrently with the review and discussions regarding the draft combination agreement, representatives of NYSE Group, Euronext, Wachtell Lipton, Cleary Gottlieb, Darrois Villey Maillot Brochier (NYSE Group's special French counsel), CMS Bureau Francis Lefebvre (NYSE Group's special French tax and employee benefits counsel), Herbert Smith LLP (NYSE Group's special U.K. counsel), Loyens & Loeff (NYSE Group's special Dutch counsel), Gonçalves Pereira Castelo Branco & Associados (NYSE Group's Special Portuguese counsel), conducted due diligence investigations with respect to NYSE Group's and Euronext's business, legal, regulatory, tax and other matters. On May 16, 2006, members of NYSE Group's and Euronext's respective senior management and their respective legal and financial advisors attended meetings in New York City to conduct due diligence and to discuss the major terms of the transaction, including exploring synergy opportunities.

On May 19, 2006, Deutsche Börse publicly announced details of a proposal for a potential merger with Euronext, which it confirmed in a letter dated May 19, 2006 to Mr. Hessels and in a letter to Mr. Théodore dated May 20, 2006 which included financial details.

On May 19, 2006, the NYSE Group board of directors held a special meeting to receive an update from management and the company's advisors on the status of negotiations with Euronext. At that meeting, NYSE Group management updated the board regarding the status of negotiations with Euronext. Citigroup presented an updated financial analysis of the transaction. Wachtell Lipton reviewed with the board the key provisions of the draft combination agreement being negotiated to effect the proposed transaction, including the consideration that would be received by NYSE Group stockholders and Euronext shareholders in the proposed transaction, the conditions that would be required to be fulfilled for the transaction to be consummated and the circumstances in which the NYSE Group board of directors and the Euronext boards could consider alternative transactions that each might deem superior to the proposed transaction. The NYSE Group board was also informed that the proposed combination agreement contained only an expense reimbursement provision (and not a termination fee provision), payable by either party to the other in the event that either party terminated the combination agreement to accept an alternative proposal that its board deemed superior for NYSE Group stockholders (in the case of NYSE Group) or Euronext shareholders (in the case of Euronext) after consulting with its financial and legal advisors, and under certain other circumstances. The NYSE Group board of directors discussed at length the strategic aspects of the transaction, the advantages, including the way in which the transaction would further the company's objectives, and the risks, including that the transaction might be only partially consummated or not consummated at all. The board also considered the financial strength of the combined company and the amount of equity that it would need to achieve the company's objectives and ensure competitiveness going forward. The board also discussed the benefits that the proposed transaction would provide to NYSE Group stockholders, the challenges that would be encountered in combining the cultures and the operations of NYSE Group and Euronext, technological aspects of the combined company's trading platforms, the legal structure of the combined company as well as U.S. and European regulatory requirements. Representatives from Citigroup then presented financial analyses of the proposed transaction and indicated that, as of the date of the meeting, Citigroup was prepared to deliver an opinion that the aggregate consideration to be offered to the Euronext shareholders in the proposed combination was fair from a financial point of view to NYSE Group. The NYSE Group board also reviewed and considered, with NYSE Group's financial and legal advisors, the factors described under "The Combination—NYSE Group's Reasons for the Combination," as well as regulatory approval risks, the process of SEC review of the proposed transaction and risks, such as non-consummation or failure of integration, in connection with the proposed transaction. The board agreed to meet telephonically the following day to discuss the transaction further.

On May 20, 2006, the NYSE Group board of directors held another meeting to discuss the potential transaction with Euronext. After further discussing the potential benefits and risks associated with the transaction, the NYSE Group board of directors determined that pursuing the proposed combination with Euronext was in the best interest of NYSE Group and its stockholders. It therefore instructed NYSE Group management to present a public proposal to the Euronext supervisory board in advance of

Euronext's annual general shareholders meeting that was scheduled to be held on May 23, 2006, at which meeting the Euronext shareholders, at the request of one of its shareholders, would be asked to vote on the principle that a merger between Deutsche Börse and Euronext was in the best interests of all the shareholders of Euronext.

Accordingly, on May 22, 2006, Mr. Carter, chairman of the NYSE Group board of directors, and Mr. Thain sent a letter to Mr. Hessels, the chairman of the Euronext supervisory board, and Mr. Théodore, confirming the terms of NYSE Group's proposal for the business combination. Under the terms of the proposal, Euronext shareholders would be offered the right to exchange each Euronext ordinary share for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock in an exchange offer, and each share of outstanding NYSE Group common stock would be converted into one share of NYSE Euronext common stock in a subsequent merger. Based on the closing price of NYSE Group common stock of $64.50 on May 19, 2006, the consideration would be equivalent to an exchange ratio of 1.4 shares of NYSE Euronext common stock for each Euronext ordinary share, with 30% of the aggregate consideration paid in cash. The exchange offer would include a mix-and-match election to permit Euronext shareholders to elect more cash or more stock to the extent that either is available. The proposed transaction terms would also assume that Euronext would pay to its shareholders its regular annual dividend of €1 per share with respect to the 2005 financial year and Euronext's previously announced return of €3 per share by way of repayment of share capital, without any decrease to the exchange offer consideration. Under the proposal, the board of the combined company would be comprised of 20 directors, 11 of whom would be former NYSE Group directors and 9 of whom would be former Euronext supervisory directors or designees of Euronext (the parties would later agree to increase the size of the board of the combined company so that it would be comprised of 22 directors, 12 of whom would be former NYSE Group directors or designees of NYSE Group and 10 of whom would be former Euronext supervisory directors or designees of Euronext). The proposal provided that the chairman of the combined company would be Mr. Hessels and the deputy chairman would be Mr. Carter. Mr. Thain would be the chief executive officer of the combined company, and Mr. Théodore would be deputy chief executive officer of the combined company. The common stock of the combined company would be listed on both the NYSE and Euronext Paris (Eurolist by Euronext), and traded in the local currency on each market.

That same day, NYSE Group publicly disclosed its proposal to Euronext and held an investor conference to explain the terms and conditions of its proposal, as well as the rationale underlying its proposal.

On May 22, 2006, after receipt of Mr. Carter's and Mr. Thain's letter of the same day, the Euronext supervisory and managing boards met in preparation for the annual general meeting of Euronext shareholders to be held the following day. Having received proposals regarding a combination from each of Deutsche Börse and NYSE Group, the Euronext boards reviewed and compared the proposals carefully and considered their relative merits from the perspective of shareholders and other stakeholders, based on presentations made by Euronext's financial advisors, Morgan Stanley and ABN AMRO, and its legal advisor, Stibbe. The Euronext boards specifically reviewed and compared the proposals in respect of the same elements as those reviewed during the April 29, 2006 board meeting and the criteria set out in Euronext's April 3, 2006 press release. In particular, the boards focused on the then-current status of the discussions with NYSE Group and Deutsche Börse, respectively, regarding the key objective of a balanced corporate governance structure that would be enshrined in the constitutional documents of the combined company, as well as on the potential for regulatory issues to delay or prevent the consummation of the respective proposed combinations. The Euronext boards reached the conclusion that, based on the proposals received, the transaction with NYSE Group offered the most attractive combination, and resolved to explain both proposals at the annual meeting of Euronext shareholders to be held the next day.

On May 23, 2006, Euronext held its annual meeting of shareholders. At this meeting, the NYSE Group proposal and the Deutsche Börse proposal were explained to Euronext shareholders. Among the items to be voted on was agenda item 10b, requested to be included on the agenda by Euronext's

shareholder, Winchfield Holdings N.V., which stated "the principle that a merger between Deutsche Börse and Euronext is in the best interests of all the shareholders of Euronext." The Euronext managing and supervisory boards unanimously recommended that Euronext shareholders vote against item 10b. After extensive discussions and questions-and-answers at the meeting, the Euronext shareholders voted against the Winchfield resolution, with approximately 43.9 million votes cast against, approximately 30.6 million votes cast in favor and approximately 6.6 million abstentions.

On May 23, 2006, after the completion of Euronext's annual meeting of shareholders, the Euronext supervisory and managing boards reconvened to discuss the outcome of the shareholders meeting, in the presence of the company's financial advisors, Morgan Stanley and ABN AMRO, and its legal advisor, Stibbe. The boards reviewed the various questions asked and comments made by shareholders during the meeting earlier that day, as well as the outcome of the vote on the proposal submitted by Winchfield Holdings N.V. The boards resolved that the negotiations with NYSE Group on an agreement regarding the proposed combination should continue.

From May 23, 2006 to June 1, 2006, NYSE Group, Euronext and their respective financial and legal advisors continued to negotiate the terms of the combination agreement, with a focus on the key governance aspects of the combination. In addition to the composition of the board and management that had been part of prior drafts of the combination agreement, NYSE Group and Euronext agreed that the bylaws of the combined company would provide that certain decisions of the board of the combined company, including certain acquisitions undertaken by the combined company, would require approval of two-thirds of the directors of the combined company, thereby ensuring that both U.S. domiciliaries and European domiciliaries on the board would have to approve such transactions. In addition, NYSE Group and Euronext agreed that the bylaws of the combined company would provide that the positions of chairman of the board of directors and chief executive officer of NYSE Euronext would always be filled by one person who is a European domiciliary and one person who is a U.S. domiciliary and that the nominating and governance committee of the combined company's board of directors would be composed of an equal number of U.S. domiciliaries and European domiciliaries. These provisions could only be amended with the approval of 80% of the combined company's shareholders or two-thirds of its directors then in office.

By June 1, 2006, NYSE Group, Euronext and their respective financial and legal advisors finalized the terms of the proposed combination agreement.

On that day, a joint meeting of the Euronext managing board and supervisory board was held, again in the presence of its financial advisors, Morgan Stanley and ABN AMRO, and its legal advisor, Stibbe. The boards considered the outcome of the negotiations that had taken place with NYSE Group and its advisors since May 23, 2006, based on presentations given by their advisors, including a comparison of the terms and key considerations of the proposed transaction with NYSE Group and the latest proposal of Deutsche Börse, being the proposal received by Euronext on May 20, 2006, as well as a summary of the proposed combination agreement between Euronext and NYSE Group. Among other things, the boards noted the improvements agreed to with respect to a balanced corporate governance structure for the combined company, to be enshrined in its certificate of incorporation and bylaws, and the consideration given in that context to the relevant regulatory aspects of the transaction and the proposed combination. The Euronext boards also reviewed and considered with their financial and legal advisors various factors described under "The Combination—Euronext's Reasons for the Combination." Representatives from Morgan Stanley and ABN AMRO provided a financial analysis of the transaction and Morgan Stanley rendered its oral opinion, subsequently confirmed in writing by each financial advisor, that, as of June 1, 2006, and based upon and subject to the assumptions and other limitations set forth in its opinion, the consideration to be received by the Euronext shareholders in the exchange offer was fair from a financial point of view to the Euronext shareholders, as a whole. In addition, representatives from ABN AMRO rendered to the Euronext supervisory and managing boards the opinion of ABN AMRO that, as of June 1, 2006, and based upon and subject to the assumptions, qualifications and other considerations set forth in its opinion, the

standard offer consideration to be offered to the Euronext shareholders in the exchange offer was fair from a financial point of view to the Euronext shareholders. After deliberation, the Euronext supervisory board determined that the combination agreement and the transactions contemplated thereby presented the most attractive solution in the context for Euronext, its shareholders and other stakeholders and the supervisory board authorized the managing board to sign the combination agreement on behalf of Euronext.

That same day, the NYSE Group board of directors met again to consider the proposed transaction. At the meeting, NYSE Group management updated the board on its discussions with Euronext and reviewed the updated terms of the proposed combination agreement. Representatives from Wachtell Lipton described the updated terms of the combination agreement and governance arrangements proposed to be entered into in connection with the combination. Representatives from Citigroup provided a financial analysis of the transaction and rendered Citigroup's oral opinion, subsequently confirmed in writing, that, as of June 1, 2006 and based upon and subject to the various considerations set forth in the opinion, the consideration to be offered to the Euronext shareholders in the proposed combination was fair from a financial point of view to NYSE Group. The NYSE Group board of directors also reviewed and considered, with NYSE Group's financial and legal advisors, the factors described under "The Combination—NYSE Group's Reasons for the Combination." After deliberations, the NYSE Group board of directors determined that the combination agreement and the transactions contemplated by the combination agreement were fair and in the best interest of NYSE Group and its stockholders and authorized management to execute the combination agreement on behalf of the company.

Shortly thereafter, NYSE Group and Euronext entered into the combination agreement.

NYSE Group's Reasons for the Combination

On June 1, 2006, the NYSE Group board of directors determined that the combination agreement and the transactions contemplated by the combination agreement were advisable, fair to and in the best interests of NYSE Group stockholders and approved and adopted the combination agreement and the transactions contemplated by the combination agreement. The combination agreement provides that the NYSE Group board of directors will recommend that the NYSE Group stockholders vote for the approval and adoption of the combination agreement and the transactions contemplated by the combination agreement.

In reaching this decision, the NYSE Group board of directors consulted with NYSE Group management and its financial and legal advisors and considered a variety of factors, including the material factors described below. In light of the number and wide variety of factors considered in connection with its evaluation of the transaction, the NYSE Group board of directors did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its determination. The NYSE Group board of directors viewed its position as being based on all of the information available and the factors presented to and considered by it. In addition, individual directors may have given different weight to different factors. This explanation of NYSE Group's reasons for the proposed combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under "Forward-Looking Statements."

Strategic Considerations

The NYSE Group board of directors considered a number of factors pertaining to the strategic rationale for the combination as generally supporting its decision to enter into the combination agreement, including the following:

•: its expectation that the combined company would be the world's first truly global exchange and the world's largest securities marketplace, encompassing seven exchanges in six countries, including Belgium, France, the Netherlands, Portugal, the United Kingdom and the United States;

•: its expectation that the combined company would be a leader in a diverse set of large and growing businesses, including cash equities, listings, derivatives, equity options and futures, bonds, market data and technology;
•: its expectation that the combined company would be the home to the world's premier listing venues, with a total worldwide market capitalization of listed issuers of $27 trillion (as of April 30, 2006);
•: its expectation that the combined company would be led by an experienced global board and world-class leadership team, with its U.S. headquarters located at NYSE Group's current headquarters and the headquarters of its non-U.S. business located at Euronext's current headquarters;
•: NYSE Group's and Euronext's shared commitment to the highest standards of quality, innovation and governance;
•: NYSE Group's and Euronext's common vision of technology strategy and a business model that does not include the clearing and settlement of trades as a key driver of revenues and/or profits (i.e., a horizontal business model);
•: its expectation that the combined company will be able to compete effectively for non-U.S. listings outside of the United States using the NYSE and Euronext brands, offering sizable liquidity within Europe as an alternative for companies that do not want to be subject to the U.S. regulatory and legal regime;
•: its expectation that the combined company will have the ability to offer additional services in Europe to companies listing in the United States, such as investor relations outreach programs for non-European issuers interested in European visibility; and
•: its expectation that the combination will over time create substantial incremental efficiency and growth opportunities.

For a discussion of NYSE Euronext's strategy for taking advantage of these strengths of the combined company after the combination, see "Information About NYSE Euronext—NYSE Euronext's Competitive Strengths" and "Information About NYSE Euronext—NYSE Euronext's Strategy."

Financial Considerations

The NYSE Group board of directors also considered a number of financial factors pertaining to the combination as generally supporting its decision to enter into the combination agreement, including the following:

•

based on the advice of NYSE Group management who had discussions with Euronext management, its expectation that the combination would create significant cost savings and revenue synergies, including:

•: approximately $275 million of annual cost savings, achievable within three years after the combination (with approximately $55 million of these cost savings achieved by 2007, $125 million by 2008 and the full $275 million by 2009); and
•: approximately $100 million of annual incremental revenue, achievable within three years after the combination;

•

the financial terms of the exchange offer and the merger, including:

•: the €21.32 in cash and 0.98 of a share of NYSE Euronext common stock that Euronext shareholders would receive in the exchange offer for each of their Euronext shares;
•: the one share of NYSE Euronext common stock that NYSE Group stockholders would receive in the merger for each of their shares of NYSE Group common stock;

•: the earnings, cash flow and balance sheet impact of the proposed combination, as well as the historical financial performance of NYSE Group and the historical trading price of NYSE Group common stock; and
•: the expectation that NYSE Group stockholders will hold approximately 59% of the outstanding shares of NYSE Euronext immediately after the combination and will have the opportunity to share in the future growth and expected synergies of the combined company; and

•: the financial analyses and opinion of Citigroup, NYSE Group's financial advisor, that, as of June 1, 2006 and based upon and subject to the considerations and limitations set forth in the opinion, Citigroup's financial analysis and other factors that Citigroup deemed relevant, the aggregate consideration to be paid by NYSE Euronext in the exchange offer is fair, from a financial point of view, to NYSE Group.

Other Transaction Considerations

The NYSE Group board of directors also considered a number of additional factors in its decision to enter into the combination agreement, including the following:

•

the proposed structure of the NYSE Euronext board of directors, which would initially include the following:

•: the chairman of the Euronext supervisory board as of immediately prior to the combination (who is expected to be the chairman of the NYSE Euronext board of directors);
•: the chairman of the NYSE Group board of directors as of immediately prior to the combination (who is expected to be deputy chairman of the NYSE Euronext board of directors);
•: the chief executive officer of NYSE Group as of immediately prior to the combination (who is expected to be the chief executive officer of NYSE Euronext);
•: the chief executive officer of Euronext as of immediately prior to the combination (who is expected to be deputy chief executive officer of NYSE Euronext);
•: nine other individuals who were directors of NYSE Group as of immediately prior to the combination; and
•: seven other individuals who were members of the Euronext supervisory board as of immediately prior to the combination (provided that Euronext may substitute one or more such individuals from its supervisory board with persons whose domicile is a European country, if such person is reasonably acceptable to NYSE Group);

•

the board of directors of NYSE Euronext would consist of 11 U.S. domiciliaries and 9 European domiciliaries (the parties subsequently agreed that the board of directors of NYSE Euronext would consist of 12 U.S. domiciliaries and 10 European domiciliaries), and this composition requirement could not be changed without the approval of two-thirds of the directors then in office or 80% of the outstanding common stock of NYSE Euronext;

•

the nominating and governance committee of NYSE Euronext would consist of an equal number of U.S. domiciliaries and European domiciliaries, and this composition requirement could not be changed without the approval of two-thirds of the directors then in office or 80% of the outstanding common stock of NYSE Euronext;

•

the positions of chairman of the board of directors and chief executive officer of NYSE Euronext would be filled by one person who is a U.S. domiciliary and one person who is a European domiciliary;

•: acquisitions, dispositions, mergers and consolidations involving greater than 30% of the aggregate equity market capitalization or value of NYSE Euronext, or involving an entity whose principal place of business is outside of the United States and Europe pursuant to which NYSE Euronext has agreed that one or more directors of the board of directors of NYSE Euronext shall be a person who is neither a U.S. domiciliary nor a European domiciliary, would require approval of two-thirds of the directors then in office, and this requirement could not be changed without the approval of two-thirds of the directors then in office or 80% of the outstanding common stock of NYSE Euronext;
•: the proposed management committee of NYSE Euronext, which would initially include an equal number of designees of NYSE Group (including the chief executive officer of NYSE Group as of immediately prior to the combination) and of designees of Euronext (including the chief executive officer of Euronext as of immediately prior to the combination);
•: the expectation that the merger would qualify as a reorganization for U.S. federal income tax purposes and that, as a result, the exchange by NYSE Group stockholders of their shares of NYSE Group common stock for shares of NYSE Euronext common stock in the merger generally would not be taxable to the NYSE Group stockholders for U.S. federal income tax purposes (see "The Combination—Material U.S. Federal Income Tax Consequences—Tax Consequences of the Merger to U.S. Holders of NYSE Group Common Stock");
•: information concerning NYSE Group's and Euronext's businesses, historical financial performance and condition, operations, properties, assets, regulatory issues, competitive positions, prospects and management;
•: the current and prospective economic and competitive environment facing the securities industry and NYSE Group in particular, including the anticipated consolidation in the industry and the competitive effects of this consolidation on NYSE Group;
•: the historical market prices, volatility and trading information with respect to NYSE Group common stock and Euronext shares;
•: the risks and uncertainties associated with the strategic alternatives available to NYSE Group, including the rapid technological and regulatory changes being confronted by the financial services industry and the risks and challenges associated with these changes;
•: the U.S. and European regulatory requirements that would be applicable to the combined company;
•: the material terms of the combination agreement (see "The Combination Agreement"), including the nature and scope of the closing conditions and the ability of the NYSE Group board of directors to terminate the combination agreement with Euronext to pursue an alternative proposal that it deems superior for NYSE Group stockholders subject to, and in accordance with, the terms of the combination agreement;
•: the lack of antitrust issues associated with a business combination transaction between NYSE Group and Euronext, resulting in expedited closure and execution by an experienced management team; and
•: the view of the board of directors that the satisfaction of the conditions to completion of the combination was probable within a reasonable period of time.

Risks

The NYSE Group board of directors also considered a number of uncertainties, risks and other potentially negative factors associated with the combination, including the following:

•: the value of the NYSE Euronext common stock at the time of the closing of the merger could be lower than the price of NYSE Group common stock as of the date of the combination agreement as a result of, among other things, a change in the value of the assets and liabilities of the NYSE Group and Euronext;
•: the risk that the amount of cost savings and revenue synergies that are actually achieved by NYSE Euronext turn out to be less than originally projected;
•: the possibility that regulatory or governmental authorities in the United States and Europe might seek to impose conditions on or otherwise prevent or delay the combination;
•: the risks and costs to NYSE Group if the combination is not completed, including the potential diversion of management and employee attention, potential employee attrition and the potential effect on business and customer relationships;
•: the risk that the potential benefits of the combination may not be fully or partially realized, recognizing the many potential management and regulatory challenges associated with successfully combining the businesses of NYSE Group and Euronext;
•: the risk of diverting management focus and resources from other strategic opportunities and from operational matters, and potential disruption associated with combining and integrating the companies;
•: the risk that certain members of NYSE Group senior management who have been selected to hold senior management positions in the combined company might not choose to remain with the combined company;
•: the potential challenges and difficulties relating to integrating the operations of NYSE Group and Euronext;
•: the restrictions on the conduct of NYSE Group's business prior to the completion of the combination, requiring NYSE Group to conduct its business in the ordinary course, subject to specific limitations, which may delay or prevent NYSE Group from undertaking business opportunities that may arise pending completion of the combination;
•: the requirement that NYSE Group submit the combination agreement to its stockholders for approval in certain circumstances, even if the NYSE Group board of directors withdraws its recommendation, which could delay or prevent the NYSE Group's ability to pursue alternative proposals if one were to become available;
•: the risk that either the NYSE Group stockholders or the Euronext shareholders may fail to approve the combination, or that an insufficient number of Euronext shareholders tender their Euronext shares into the exchange offer;
•: the requirement that NYSE Group pay Euronext expense reimbursement if the combination agreement were to be terminated and if the NYSE Group board of directors changes its recommendation of the proposed combination, the NYSE Group stockholders fail to approve the proposed combination or, in certain circumstances, if NYSE Group receives an acquisition proposal relating to another transaction (see "The Combination Agreement—Termination");
•: the risk that because the exchange ratio to be paid to the NYSE Group stockholders is fixed, the value of the consideration to NYSE Group stockholders in the combination could fluctuate;

•: that some officers and directors of NYSE Group have interests in the combination as individuals in addition to, and that may be different from, the interests of NYSE Group stockholders (see "The Combination—Interests of Officers and Directors in the Combination");
•: the risk that, under the terms of the shareholders agreement with Borsa Italiana, Euronext may be required to sell to Borsa Italiana its 51% stake in the parent company of MTS, a company specialized in the trading of government bonds, for fair market value, or to acquire Borsa Italiana's 49% stake for a price based on Euronext's acquisition cost and on the economic performance of MTS;
•: the fees and expenses associated with completing the combination; and
•: various other risks associated with the combination and the business of the NYSE Group, Euronext and the combined company described under "Risk Factors."

The NYSE Group board of directors believed that these potential risks and drawbacks were greatly outweighed by the potential benefits that the NYSE Group board expected NYSE Group and its stockholders to achieve as a result of the proposed combination.

In considering the proposed combination, the NYSE Group board of directors was aware of the interests of certain officers and directors of, and advisors to, NYSE Group and its board in the combination, as described under "The Combination—Interests of Officers and Directors in the Combination" and "The Combination—Certain Relationships and Related-Party Transactions."

Euronext's Reasons for the Combination

On June 1, 2006, at a joint meeting of the Euronext managing and supervisory boards, the supervisory board determined that the combination agreement and the transactions contemplated by the combination agreement presented the most attractive solution in the context for Euronext and its shareholders and other stakeholders and decided to enter into the combination agreement.

In reaching this decision, the Euronext boards consulted with their financial and legal advisors and considered a variety of factors, including the material factors described below. In light of the number and wide variety of factors considered in connection with their evaluation of the transaction, the Euronext boards did not consider it practicable or possible to quantify or otherwise assign relative weights to the specific factors that they considered in reaching their determination. The Euronext boards viewed their position as being based on all of the information available and the factors presented to and considered by them. This explanation of Euronext's reasons for the proposed combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under "Forward-Looking Statements."

Strategic Considerations

The exchange sector is experiencing consolidation, which is intensifying competition among exchanges worldwide. One of the key drivers of the trend towards consolidation is the perceived benefit in combining and harmonizing technologies across exchanges in order to lower trading costs and increase liquidity. In this context, Euronext discussed possible combinations with a number of potential partners in the months preceding the joint meeting of the Euronext managing and supervisory boards on June 1, 2006. The Euronext boards considered a number of factors pertaining to the strategic rationale for the combination with NYSE Group as generally supporting their decision to enter into the combination agreement, including the following:

•: the current and prospective economic and competitive environment facing the securities industry and Euronext in particular, including the potential benefits to being one of the leading participants

in the consolidation within the industry, and their expectation that the combination with NYSE Group would permit Euronext to fully participate as consolidation in the industry continues;

•: their expectation that the combined company would be the world's first, truly global exchange and the world's largest securities/derivatives marketplace, encompassing seven exchanges in six countries, including Belgium, France, the Netherlands, Portugal, the United Kingdom and the United States;
•: their expectation that the combined company would be a leader in a diverse set of large and growing businesses, including cash equities, listings, derivatives, equity options and futures, bonds, market data and technology;
•: their expectation that the combination would represent a true merger-of-equals, with a corporate and governance structure that respects the independence of all exchanges involved as well as the flexibility necessary to preserve Euronext's federal and horizontal business model;
•: their expectation that, based on the data then available, the combined company would be the home to the world's premier listing venues, with a total worldwide market capitalization of listed issuers of €20 trillion (as of April 30, 2006);
•: their expectation that the combined company would be led by an experienced global board and world-class leadership team;
•: Euronext's and NYSE Group's shared commitment to the highest standards of quality, innovation and governance;
•: Euronext's and NYSE Group's common vision of technology strategy and a horizontal business model;
•: their expectation that the combined company would be able to compete effectively for non-U.S. listings outside of the United States using the Euronext and NYSE brands, offering sizable liquidity within Europe as an attractive alternative for companies that do not want to be subject to the U.S. regulatory and legal regime;
•: their expectation that the combined company would have opportunities to develop new products including transatlantic indices, products leveraging the NYSE brand name and new equity derivatives;
•: their expectation that the combination represents a unique opportunity for Europe and would put the European capital markets—particularly the Eurozone markets—in a strong position in the rapid globalization of the sector;
•: their expectation, which was subsequently confirmed by the SEC in public statements, that there would be no U.S. regulatory risks for the European markets, with the European markets and Euronext-listed companies continuing to be regulated exclusively by European regulators and, in particular, with the Sarbanes-Oxley Act continuing to be applicable only to companies that list or register in the United States;
•: their expectation that Euronext's federal approach would be maintained with the opportunity to attract and consolidate new European markets;
•: their expectation that NYSE Euronext would also be an attractive platform for further consolidation globally; and
•: their expectation that the combination would over time create substantial incremental efficiency and growth opportunities produced by combining seven international securities marketplaces leveraging best-in-class technology, synergies and management expertise.

For a discussion of NYSE Euronext's strategy for taking advantages of these strengths of the combined company after the combination, see "Information About NYSE Euronext—Euronext's Strategy."

Financial Considerations

The Euronext managing and supervisory boards also considered a number of financial factors pertaining to the combination as generally supporting their decision to enter into the combination agreement, including the following:

•

their belief that the combined company, as a leader in the consolidation in the securities industry, would be well positioned to have attractive long-term financial results that could lead to share price appreciation that would benefit Euronext shareholders to the extent that they retain shares of NYSE Euronext received in the exchange offer;

•

their expectation that Euronext shareholders would hold a substantial percentage of the outstanding shares of NYSE Euronext immediately after the combination and would have the opportunity to share in the future growth and expected synergies of the combined company;

•

their expectation that the combination would create significant cost savings and revenue synergies;

•

the financial terms of the exchange offer and the merger, including:

•: the €21.32 in cash and 0.98 of a share of NYSE Euronext common stock that Euronext shareholders would receive in the exchange offer for each of their Euronext shares;
•: the "mix-and-match" election permitting Euronext shareholders to elect whether to receive cash or NYSE Euronext shares, subject to proration in the event either choice is oversubscribed;
•: the one share of NYSE Euronext common stock that NYSE Group stockholders would receive in the merger for each of their shares of NYSE Group common stock;
•: the earnings, cash flow and balance sheet impact of the proposed combination, as well as the historical financial performance of Euronext (and NYSE Group) and the historical trading price of Euronext shares and NYSE Group common stock; and

•

the financial analyses of Morgan Stanley and ABN AMRO, Euronext's financial advisors, in addition to the opinion of Morgan Stanley, that, as of June 1, 2006, and based upon and subject to the assumptions and other limitations set forth in its opinion, the consideration to be received by the Euronext shareholders in the exchange offer was fair from a financial point of view to the Euronext shareholders, as a whole, and the opinion of ABN AMRO that, as of June 1, 2006, and based upon and subject to the assumptions, qualifications and other considerations set forth in its opinion, the standard offer consideration to be offered to the Euronext shareholders in the exchange offer was fair from a financial point of view to the Euronext shareholders.

Other Transaction Considerations

The Euronext managing and supervisory boards also considered a number of additional factors in their decision to enter into the combination agreement, including the following:

•

the proposed structure of the NYSE Euronext board of directors, which would initially include the following:

•: the chairman of the Euronext supervisory board as of immediately prior to the combination (who is expected to be the chairman of the NYSE Euronext board of directors);

•: the chairman of the NYSE Group board of directors as of immediately prior to the combination (who is expected to be deputy chairman of the NYSE Euronext board of directors);
•: the chief executive officer of NYSE Group as of immediately prior to the combination (who is expected to be the chief executive officer of NYSE Euronext);
•: the chief executive officer of Euronext as of immediately prior to the combination (who is expected to be deputy chief executive officer of NYSE Euronext);
•: ten other individuals who were directors of NYSE Group as of immediately prior to the combination; and
•: eight other individuals who were members of the Euronext supervisory board as of immediately prior to the combination;

•: the board of directors of NYSE Euronext would continue to consist of 11 U.S. domiciliaries and 9 European domiciliaries (the parties subsequently agreed that the board of directors of NYSE Euronext would consist of 12 U.S. domiciliaries and 10 European domiciliaries), and this composition requirement could not be changed without the approval of two-thirds of the directors then in office or the holders of 80% of the outstanding common stock of NYSE Euronext;
•: the nominating and governance committee of NYSE Euronext would consist of an equal number of U.S. domiciliaries and European domiciliaries, and this composition requirement could not be changed without the approval of two-thirds of the directors then in office or the holders of 80% of the outstanding common stock of NYSE Euronext;
•: the position of chairman of the board or of chief executive officer of NYSE Euronext would be filled by a European domiciliary and the other position would be filled by a U.S. domiciliary, and this balancing requirement could not be changed without the approval of two-thirds of the directors then in office or the holders of 80% of the outstanding common stock of NYSE Euronext;
•: acquisitions, dispositions, mergers and consolidations involving greater than 30% of the aggregate equity market capitalization or value of NYSE Euronext, or involving an entity whose principal place of business is outside of the United States and Europe pursuant to which NYSE Euronext has agreed that one or more directors of the board of directors of NYSE Euronext shall be a person who is neither a U.S. domiciliary nor a European domiciliary, would require approval of two-thirds of the directors then in office, and this requirement could not be changed without the approval of two-thirds of the directors then in office or 80% of the outstanding common stock of NYSE Euronext;
•: the proposed management committee of NYSE Euronext, which would include an equal number of designees of NYSE Group (including the chief executive officer of NYSE Group as of immediately prior to the combination) and designees of Euronext (including the chief executive officer of Euronext as of immediately prior to the combination);
•: the intention to preserve Euronext's and NYSE Group's decentralized management policies;
•: the expectations that the exchange offer generally would allow those Euronext shareholders subject to French and U.K. tax laws to exchange their Euronext shares for NYSE-Euronext shares tax-free (except to the extent of cash received), but that the combination agreement contemplates that the receipt by holders of Euronext shares of the offer consideration in the exchange offer and in the post-closing reorganization will be structured as a taxable transaction for U.S. federal income tax purposes, unless NYSE Group elects, subject to the provisions of the combination agreement, to structure the post-closing reorganization so that, in the opinion of counsel to NYSE Group, the exchange offer together with the post-closing reorganization, is treated either as a reorganization

within the meaning of Section 368(a) of the Internal Revenue Code or an exchange described in Section 351 of the Internal Revenue Code (see "The Combination—Material U.S. Federal Income Tax Consequences");

•: information concerning Euronext's and NYSE Group's businesses, historical financial performance and condition, operations, properties, assets, regulatory issues, competitive positions, prospects and management;
•: the historical market prices, volatility and trading information with respect to Euronext shares and NYSE Group common stock;
•: the risks and uncertainties associated with the strategic alternatives available to Euronext, including the antitrust considerations, and the rapid technological and regulatory changes being confronted by the financial services industry and the risks and challenges associated with these changes;
•: the balance of European and U.S. regulatory requirements that would be applicable to the combined company;
•: the material terms of the combination agreement (see "The Combination Agreement"), including the nature and scope of the closing conditions and the ability of the Euronext boards to terminate the combination agreement with NYSE Group to pursue an alternative proposal that it deems superior for Euronext shareholders subject to, and in accordance with the terms of, the combination agreement;
•: the lack of competition law or antitrust issues associated with a business combination transaction between Euronext and NYSE Group, resulting in expedited closure and execution by an experienced management team;
•: the view of the board of directors that the satisfaction of the conditions to completion of the combination was probable within a reasonable period of time;
•: the opportunity for European investors to gain better access to many of the world's best and fastest-growing companies, the widest diversity of investment products, and best execution in speed and price;
•: their expectation of an increased opportunity, as a result of the freer flow of capital across the Atlantic, for European investors to diversify their portfolios;
•: the potential for Euronext-listed companies to benefit from increased exposure to U.S. investors, as well as inclusion in NYSE-Euronext indices and exchange-traded funds; and
•: the potential that the combined company's global market will strengthen opportunities for more robust growth and new jobs within Europe.

Risks

The Euronext managing and supervisory boards also considered a number of uncertainties, risks and other potentially negative factors associated with the combination, including the following:

•: the fact that the value of the per share consideration payable to Euronext shareholders (consisting of NYSE Euronext common stock and cash) at the time of the closing of the exchange offer cannot be predicted and will depend on, among other things, the perceived prospects of Euronext, NYSE Group or the combined company or the value of their respective assets and liabilities;
•: the challenges and potential difficulties relating to integrating the operations of Euronext and NYSE Group and the risk that the potential benefits of the combination may not be fully or partially realized;

•: the risk that the amount of cost savings and revenue synergies that are actually achieved by NYSE Euronext could turn out to be less than originally projected;
•: the possibility that regulatory or governmental authorities in Europe and the United States might seek to impose conditions on or otherwise prevent or delay the combination;
•: the risks and costs to Euronext if the combination is not completed, including the potential diversion of management and employee attention, potential employee attrition, the potential effect on business and customer relationships and costs and expenses;
•: the risk of diverting management focus and resources from other strategic opportunities and from operational matters, and potential disruption associated with the combination and integrating the companies;
•: the risk that certain members of Euronext senior management who would be selected to hold senior management positions in the combined company might not choose to remain with the combined company and the risk that certain members of Euronext senior management who are not selected to hold senior management positions in the combined company might not choose to remain with Euronext;
•: the restrictions on the conduct of Euronext's business prior to the completion of the combination, requiring Euronext to conduct its business in the ordinary course, subject to specific limitations, which could delay or prevent Euronext from undertaking business opportunities that might arise pending completion of the combination;
•: the requirement in the combination agreement that Euronext submit the combination to its shareholders for approval in certain circumstances, and for the exchange offer to be made after such approval, even if the Euronext's boards withdraw their recommendation, which requirements could delay or prevent Euronext's ability to pursue alternative proposals if one were to become available;
•: the risk that either the Euronext shareholders or the NYSE Group stockholders could fail to approve the combination, or that an insufficient number of Euronext shareholders could tender their Euronext shares into the exchange offer;
•: the requirement that Euronext reimburse NYSE Group's expenses if the combination agreement were to be terminated after the Euronext boards changed their recommendation of the proposed combination, the Euronext shareholders failed to approve the proposed combination or, in certain circumstances, Euronext received an acquisition proposal relating to another transaction (see "The Combination Agreement—Termination");
•: the fees and expenses associated with completing the combination; and
•: various other risks associated with the combination and the business of the NYSE Group, Euronext and the combined company described under "Risk Factors."

In approving the combination, the Euronext managing and supervisory boards believed that these potential risks and drawbacks were greatly outweighed by the potential benefits that the boards expected Euronext and its shareholders and other stakeholders to achieve as a result of the proposed combination.

In considering the proposed combination, the Euronext managing and supervisory boards were aware of the interests of certain of their members and of certain advisors to Euronext in the combination, as described under "The Combination—Interests of Officers and Directors in the Combination—Interests of Euronext Directors and Executive Officers" and "The Combination—Certain Relationships and Related-Party Transactions."

Certain Projections

Neither NYSE Group nor Euronext as a matter of course publicly discloses detailed forecasts or internal projections as to future revenues, earnings or financial condition.

While these projections were prepared in good faith by NYSE Group management and Euronext management, no assurance can be made regarding future events. The estimates and assumptions underlying the projections involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions and future business decisions that may not be realized and are inherently subject to significant business, economic, competitive and regulatory uncertainties, all of which are difficult to predict and many of which are beyond the control of NYSE Group and Euronext and will be beyond the control of NYSE Euronext. Accordingly, there can be no assurance that the projected results will be realized or that actual results will not differ materially from those presented in the financial data. Such projections cannot, therefore, be considered a reliable predictor of future operating results, and this information should not be relied on as such.

Opinion of NYSE Group's Financial Advisor

NYSE Group retained Citigroup to act as its financial advisor in connection with the proposed combination with Euronext. Pursuant to Citigroup's engagement letter with NYSE Group, Citigroup rendered to the NYSE Group board of directors on June 1, 2006 an oral opinion, which was subsequently confirmed by delivery of a written opinion, dated June 1, 2006, to the effect that, as of the date of the opinion and based upon and subject to the considerations and limitations set forth in the opinion, Citigroup's work described below and other factors it deemed relevant, the aggregate consideration to be paid by NYSE Euronext in the exchange offer is fair, from a financial point of view, to NYSE Group.

The full text of Citigroup's written opinion, which sets forth the assumptions made, general procedures followed, matters considered and limits on the review undertaken, is included as Annex B to this document and is incorporated into this document by reference. The summary of Citigroup's opinion set forth below is qualified in its entirety by reference to the full text of the opinion.

Holders of NYSE Group common stock are urged to read Citigroup's opinion carefully and in its entirety. Citigroup's opinion was provided for the information of the NYSE Group board of directors in its evaluation of the proposed combination with Euronext and was limited solely to the fairness, from a financial point of view, to NYSE Group as of the date of the opinion, of the aggregate consideration to be paid by NYSE Euronext in the exchange offer. Neither Citigroup's opinion nor its related analyses constituted a recommendation of the transaction with Euronext to the NYSE Group board of directors. Citigroup makes no recommendation to any stockholder regarding how such stockholder should vote or act on any matters relating to the proposed combination, including the exchange offer or the merger.

In arriving at its opinion, Citigroup reviewed the combination agreement and held discussions with certain senior officers, directors and other representatives and advisors of NYSE Group and certain senior officers and other representatives and advisors of Euronext concerning the business, operations and prospects of NYSE Group and Euronext. Citigroup examined certain publicly available business and financial information relating to NYSE Group and Euronext, as well as certain financial forecasts and other information and data relating to NYSE Group and Euronext that were provided to or otherwise reviewed by or discussed with Citigroup by the respective managements of NYSE Group and Euronext, including information relating to the potential strategic implications and operational benefits (including the amount, timing and achievability thereof) anticipated by the respective managements of NYSE Group and Euronext to result from the proposed combination, and adjustments to the forecasts and other information and data relating to Euronext discussed with Citigroup by the management of NYSE Group. In addition, Citigroup assumed, with NYSE Group's consent, that there are no material undisclosed liabilities of NYSE Group and Euronext for which adequate reserves or other provisions have not been made. Citigroup reviewed the financial terms of the acquisition of the Euronext shares as set forth in the combination agreement in relation to, among other things:

•: current and historical market prices and trading volumes of NYSE Group common stock and Euronext shares;
•: the historical and projected earnings and other operating data of each of NYSE Group and Euronext; and
•: the capitalization and financial condition of each of NYSE Group and Euronext.

Citigroup considered, to the extent publicly available, the financial terms of certain other transactions that Citigroup considered relevant in evaluating the proposed combination and analyzed certain financial, stock market and other publicly available information relating to the businesses of other companies whose operations Citigroup considered relevant in evaluating those of NYSE Group and Euronext. Citigroup also evaluated certain potential pro forma financial effects of the proposed combination on NYSE Group. In addition to the foregoing, Citigroup conducted such other analyses and examinations and considered such other information and financial, economic and market criteria as Citigroup deemed appropriate in arriving at its opinion.

In rendering its opinion, Citigroup assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with it and upon the assurances of the managements of NYSE Group and Euronext that they were not aware of any relevant information that was omitted or that remained undisclosed to Citigroup. With respect to financial forecasts and other information and data provided to or otherwise reviewed by or discussed with Citigroup relating to NYSE Group and Euronext, including certain potential pro forma effects of, and strategic implications and operational benefits anticipated to result from, the proposed combination, Citigroup was advised by the respective managements of NYSE Group and Euronext that such forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of NYSE Group and Euronext as to the future financial performance of NYSE Group and Euronext. Citigroup assumed, with NYSE Group's consent, that the financial results (including the potential pro forma financial effects, strategic implications and operational benefits anticipated to result from the proposed combination) reflected in such forecasts and other information and data will be realized in the amounts and at the times projected by NYSE Group's management. Citigroup also assumed, with NYSE Group's consent, that the proposed combination will be consummated in accordance with the terms of the combination agreement, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the proposed combination, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on NYSE Group, Euronext or the contemplated benefits of the proposed combination.

Citigroup also assumed, with NYSE Group's consent, that NYSE Euronext was organized in connection with the proposed combination and upon consummation of the proposed combination, its sole assets will be the Euronext shares acquired pursuant to the exchange offer and all of the shares of NYSE Group common stock acquired pursuant to the merger. Citigroup also assumed, with NYSE Group's consent, that the merger will be treated as a tax-free reorganization for U.S. federal income tax purposes. Citigroup did not express any opinion as to the value of the NYSE Euronext common stock when issued pursuant to the proposed combination, or the price at which the NYSE Euronext common stock will trade at any time. Citigroup did not make, and was not provided with, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of NYSE Group or Euronext, and did not make any physical inspection of the properties or assets of NYSE Group or Euronext. Citigroup expressed no view as to, and its opinion does not address, the relative merits of the proposed combination as compared to any alternative business strategies that might exist for NYSE Group or the effect of any other transaction in which NYSE Group might engage. Citigroup's opinion does not address or take into account any post-closing reorganization pursuant to the combination agreement that may occur following the closing of the exchange offer, or the consideration that may be paid pursuant to such post-closing reorganization. Citigroup's analysis assumes that 100% of the Euronext shares are acquired by NYSE Euronext for the offer consideration. Citigroup's opinion was necessarily based upon information available to Citigroup, and financial, stock market and other conditions and circumstances existing, as of the date thereof.

In connection with rendering its opinion, Citigroup made a presentation to the NYSE Group board of directors on June 1, 2006 with respect to the material financial analyses performed by Citigroup in evaluating the fairness of the aggregate consideration to be paid by NYSE Euronext in the exchange offer as of the date of Citigroup's opinion. The following is a summary of the financial analyses contained in that presentation. The summary includes information presented in tabular format. In order to understand fully the financial analyses used by Citigroup, these tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. The following quantitative information, to the extent it is based on market data, is, except as otherwise indicated, based on market data as it existed at or prior to May 31, 2006, and is not necessarily indicative of current or future market conditions.

Indicated Transaction Multiples

Citigroup calculated various multiples based on the implied transaction price per Euronext share and the related firm value ("FV"), calculated as equity value plus net debt, reflected in the exchange offer. These calculations were based on Euronext's financial statements and estimates and forecasts for Euronext prepared by NYSE management. Citigroup calculated the multiple of the Euronext FV to earnings before interest, taxes, depreciation and amortization (EBITDA) and the multiple of the implied transaction price per Euronext share to earnings per share (EPS). In addition, Citigroup calculated the premium or discount to various closing market prices of each Euronext share reflected by the implied transaction price per share. Such premium or discount was calculated on a stated price per share basis, and excluding Euronext's previously announced distribution of €3 per share by means of repayment of share capital.

The following table presents the results of these calculations (all dollar and euro amounts in millions other than per share prices):

Comparable Companies Analysis

Citigroup reviewed market values and trading multiples for the following publicly held companies in the exchange operator industry (which in this document is sometimes referred to as the "peer group") and compared them with financial data for Euronext:

•: NYSE Group;
•: NASDAQ Stock Market, Inc.;
•: Australian Stock Exchange Limited;
•: London Stock Exchange plc;
•: TSX Group Inc.;
•: International Securities Exchange, Inc.;
•: Deutsche Börse AG;
•: Hong Kong Exchanges and Clearing Limited;
•: Singapore Exchange Limited;
•: OMX Aktiebolag ("OMX");
•: Chicago Mercantile Exchange Holdings Inc.;
•: CBOT Holdings, Inc.; and
•: Intercontinental Exchange, Inc.

All multiples were based on market data as of May 31, 2006. The forecasted financial information used by Citigroup for the selected comparable companies in the course of this analysis was based on First Call and Institutional Brokers Estimate System, or IBES, as provided by Thomson Financial and IDD Information Services. First Call is a global database that provides real-time electronic access to original full text equity research reports. IBES contains estimated and actual earnings cash flows, dividends, sales and pre-tax income data for companies in the U.S., Europe, Asia and emerging markets. The forecasted financial information used by Citigroup for Euronext in the course of these analyses was based on NYSE Group management estimates and assumes Euronext fully-diluted shares of 111.975 million and exchange rates as of May 31, 2006.

For each of the selected comparable companies, Citigroup derived and compared, among other things:

•: the ratio of FV as of May 31, 2006 to 2006 estimated revenue and 2006 estimated EBITDA; and
•: the ratio of prices per share as of May 31, 2006 to estimated earnings per share for 2006, 2007 and 2008.

The following table sets forth the results of this analysis:

	Ratio of Firm Value to 2006E		Price per share/Earnings per share
Selected Companies	Ratio of Firm Value to 2006E		Price per share/Earnings per share
Selected Companies	Revenue	EBITDA	2006E	2007E	2008E
Range	4.7x-16.1x	10.0x-25.9x	17.0x-45.8x	15.4x-32.1x	13.8x-25.6x
Median	8.4x	18.2x	29.0x	24.2x	21.2x
Mean	9.0x	17.2x	30.6x	24.0x	20.6x

Based on this analysis, Citigroup derived a reference range for the implied price per Euronext share of €65.36 to €75.67. Citigroup calculated that this range of implied values would result in an implied multiple of estimated 2007 earnings per share of 19.0x to 22.0x.

Precedent Exchange Change-of-Control Analysis

Citigroup reviewed multiples of FV to LTM revenue and LTM EBITDA and multiples of equity value (EV) to LTM net income for the following selected pending or completed transactions (listed by acquirer/target, together with date of announcement) in the exchange operator industry since 2001:

•: NASDAQ/London Stock Exchange (5/10/06), based on the highest price paid by NASDAQ for its 25.1% minority stake;
•: Australian Stock Exchange/SFE Corporation Limited (3/27/06);
•: New York Stock Exchange, Inc./Archipelago Holdings, Inc. (4/20/05);
•: OMX/Copenhagen Stock Exchange A/S (11/15/04);
•: Euronext/Bolsa de Valores de Lisboa e Porto (12/13/01); and
•: Euronext/LIFFE (Holdings) plc (10/29/01).

The following table presents the results of this analysis:

			Ratio of FV to:
	Ratio of EV to:		Ratio of FV to:
Selected Transactions	Ratio of EV to:		LTM Net Income
Selected Transactions	LTM Revenue	LTM EBITDA	LTM Net Income
Range	1.9x-15.4x	8.3x-31.6x	18.2x-45.4x
Median	4.6x	18.2x	29.6x
Mean	7.0x	18.6x	30.8x

Based upon this information and financial data for Euronext, Citigroup derived a reference range for the multiple of EV to LTM net income for Euronext of 25.0x to 40.0x. Citigroup calculated that this range of multiples would result in an implied price of each Euronext share, assuming 111.975 million fully-diluted Euronext shares outstanding and after an adjustment excluding the €3 per Euronext share special dividend, of approximately €63.41 to €103.25.

Sum-of-the-Parts Analysis

Citigroup performed a sum-of-the-parts analysis to calculate the implied value of the Euronext shares based on the sum of the implied valuations for each of Euronext's principal business segments (including cash trading/listing business, derivatives trading business and other businesses) on a standalone basis. For

the purposes of this analysis, Citigroup included Euronext's indirect ownership stake in MTS in its cash trading/listing business segment and all information services, settlement and custody, sales of software and holding/unallocated lines of business were included in "other businesses." Citigroup derived reference 2007 earnings estimates from each line of business's 1Q 2006 earnings before interest, tax and amortization (EBITA), their respective percentages of Euronext's consolidated 1Q 2006 EBITA and the consolidated 2007 earnings estimate prepared by NYSE Group management. Based on these reference earnings estimates and a range of estimated multiples of price to earnings of each segment's public comparables for 2007, Citigroup calculated a range of implied valuations for each business segment on a standalone basis.

The following table sets forth the results of this analysis (all euro amounts in millions other than per share prices):

	2007E P/E Range
					Implied Valuation
Segment:					Implied Valuation
Segment:	Low		Median		Low	Median
Cash Trading/Listing	19.2	x	23.0	x	€3,122	€3,732
Derivatives Trading	26.6		31.4		4,251	5,024
Other Businesses	15.0		20.0		701	934

Total	21.9		26.3		€8,074	€9,690

	Implied Per Share Value				€72.11	€86.54

Based on this analysis, Citigroup derived a reference range for the implied value of Euronext on a consolidated basis of approximately €8,074 million to €9,690 million. Citigroup calculated that this range of implied values would result in an implied per share value, assuming 111.975 million fully-diluted Euronext shares outstanding, of €72.11 to €86.54.

Discounted Cash Flow Analysis

Citigroup performed a discounted cash flow analysis to calculate the estimated present value of the standalone after-tax free cash flows that Euronext could generate over the period from 2007 through 2011 based upon estimated net income for Euronext prepared by NYSE Group management for 2007 and 2008, and a 2009 through 2011 annual revenue growth rate of 10%. Citigroup also performed a discounted cash flow analysis to calculate the estimated present value of the standalone after-tax free cash flows that Euronext could generate over the same period taking into account 100% of approximately $375 million in annual pre-tax synergies estimated by NYSE Group management to result from the transaction, phased-in at approximately $-11 million in 2007, $94 million in 2008 and $310 million in 2009.

The discounted cash flow analysis was calculated using various additional assumptions, including the following:

•: valuation as of December 31, 2006;
•: 3% perpetuity growth for synergies;
•: depreciation and amortization expense equal to capital expenditures; and
•: change in working capital equal to 25% of annual change in revenues.

Citigroup calculated a range of estimated terminal values by applying a 3% perpetuity growth rate to 2011 estimated net income for Euronext on a standalone basis. In addition, Citigroup calculated a similar range by applying a range of terminal multiples of 16.0x-18.0x to fiscal 2012 estimated net income for Euronext on a standalone basis. The present value of the cash flows and terminal values were calculated using discount rates ranging from 9.3% to 11.3%.

In each case without taking into account any synergies, Citigroup derived a reference range for the implied value of the equity per Euronext share of approximately €63.46 to €84.89 based on the 3% perpetuity growth rate analysis and a reference range €78.73 to €93.89 based on the terminal multiples analysis.

Contribution Analysis

Based upon historical operating and financial information for the 12 months ended March 31, 2006 and NYSE Group management's 2006, 2007 and 2008 earnings estimates for Euronext and NYSE Group, Citigroup reviewed the implied contribution percentages of NYSE Group and Euronext to the combined company, unaffected by any pro forma adjustments, in terms of LTM revenues, LTM and estimated 2006, 2007 and 2008 EBITDA and LTM and estimated 2006, 2007 and 2008 net income.

Based upon the foregoing analysis, without taking into account any cost savings or revenue synergies or other transaction adjustments, Citigroup calculated an implied NYSE Group contribution range in the combined company of approximately 22% to 53%, compared with an implied ownership percentage of NYSE Group shareholders in the pro forma entity of 58.9% on a fully diluted basis.

Pro Forma Analysis

Citigroup analyzed the pro forma impact of the acquisition by NYSE Euronext of the Euronext shares on projected earnings per share (EPS) for NYSE Group, based upon fiscal 2007 and 2008 earnings estimates prepared by NYSE Group management for NYSE Group and Euronext. The effect on EPS was calculated assuming the transaction closed on December 31, 2006 and using various other assumptions, including the following:

•: approximately $375 million in annual pre-tax synergies, phased-in at approximately $-11 million in 2007 and $94 million in 2008;
•: approximately $839 million total newly-created identifiable finite-life intangibles amortized over approximately 10 years;
•: a blended tax rate of 38% on pro forma adjustments;
•: GAAP reconciliation adjustments, including listing fee amortization of approximately $-23 million pre-tax, declining $3 million per year thereafter and an additional $6 million per year of restricted stock expense, increasing 10% per year;
•: a special dividend distribution by Euronext of €3 per share pre-closing;
•: excess free cash flow used to repay transaction-related debt;
•: equivalent annual capital expenditures and pre-transaction depreciation and amortization;
•: change in working capital growth equal to 25% of change in revenues; and
•: a foreign exchange rate of $1.284 per €1.

Citigroup compared the NYSE Group management's estimate of standalone 2007 and 2008 EPS of NYSE Group (GAAP EPS) and the GAAP EPS plus after-tax effect of intangible amortization (cash EPS), to the estimated GAAP EPS and cash EPS, respectively, of the combined company using the foregoing assumptions.

		2007 Estimated					2008 Estimated
		NYSE Group Standalone		Pro Forma Combined			NYSE Group Standalone		Pro Forma Combined
Estimated GAAP EPS		$	2.24	$	2.53		$	2.81	$	3.52
	Accretion/(Dilution)				13.3	%				25.2	%
Estimated Cash EPS		$	2.26	$	2.75		$	2.84	$	3.73
	Accretion/(Dilution)				21.3	%				31.4	%

Other Factors

In rendering its opinion, Citigroup also reviewed and considered other factors for informational purposes, including:

•: the historical ratio of Euronext's stock price to next twelve months mean earnings per share estimated by IBES over the three-year period from May 31, 2003 through May 31, 2006, compared with the comparable ratios for companies in the peer group including Deutsche Börse, London Stock Exchange, CME and CBOT over the same period;
•: growth of Euronext's cash trading, listing and derivatives businesses over 2003, 2004, 2005 and the first quarter of 2006 as measured by their respective revenue, volume and other relevant metrics;
•: 2005 benchmarks of Euronext against companies in the peer group relevant for each of its main businesses, including: revenues, revenue per trade, average daily number of trades and average trade size in its cash trading business; revenue, market capitalization of domestic listed companies, IPO capital raised and number of IPOs in its listing business; and revenue, contracts traded by product, mix of contracts and revenue per average contract traded in its derivatives business;
•: the operating margin, growth and business mix statistics of NYSE Group, Euronext and the peer group. Estimates for the peer group were based on median estimates obtained from IBES. Estimates for NYSE Group and Euronext were based on NYSE management projections; and
•: precedent European and United States "merger of equal" transactions in the financial institutions industry since 1995, including their deal values, 1-day premiums paid by acquirer, the respective ownership percentages and board representation of acquirer and target in the resulting entity and other indicators (including the selection of chairman, CEO, corporate headquarters and brand).

Based on the analyses described above, Citigroup determined that the aggregate consideration to be paid by NYSE Euronext in the exchange offer is fair, as of the date of the opinion, from a financial point of view, to NYSE Group.

Citigroup's opinion was provided for the information of the NYSE Group board of directors in its evaluation of the proposed transaction with the holders of the Euronext shares and was limited solely to the fairness, from a financial point of view, as of the date of the opinion, of the aggregate consideration to be paid by NYSE Euronext to the holders of the Euronext shares for the acquisition of the Euronext shares. Neither Citigroup's opinion nor its related analyses constituted a recommendation of the transaction with the holders of the Euronext shares to the NYSE Group board of directors. Citigroup makes no recommendation to any stockholder regarding how such stockholder should vote or act on any matters relating to the transactions, including the merger and the payment by NYSE Euronext of the aggregate consideration to holders of the Euronext shares.

The preceding discussion is a summary of the material financial analyses furnished by Citigroup to the NYSE Group board of directors, but it does not purport to be a complete description of the analyses performed by Citigroup or of its presentation to the NYSE Group board of directors. The preparation of financial analyses and fairness opinions is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description. Citigroup made no attempt to assign specific weights to particular analyses or factors considered, but rather made qualitative judgments as to the significance and relevance of all the analyses and factors considered and determined to give its fairness opinion as described above. Accordingly, Citigroup believes that its analyses, and the summary set forth above, must be considered as a whole, and that selecting portions of the analyses and of the factors considered by Citigroup, without considering all of the analyses and factors, could create a misleading or incomplete view of the processes underlying the analyses conducted by Citigroup and its opinion. With regard to the comparable companies and precedent transactions analyses summarized above, Citigroup selected comparable public companies and precedent transactions on the basis of various factors, including size and similarity of the line of business of the relevant entities; however, no company utilized in these analyses is identical to Euronext and no precedent transaction is identical to the proposed transaction with

holders of the Euronext shares. As a result, these analyses are not purely mathematical, but also take into account differences in financial and operating characteristics of the subject companies and other factors that could affect the proposed transaction with holders of the Euronext shares or public trading value of the subject companies to which Euronext is being compared.

In its analyses, Citigroup made numerous assumptions with respect to NYSE Group and Euronext, industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of NYSE Group and Euronext. Any estimates contained in Citigroup's analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by these analyses. Estimates of values of companies do not purport to be appraisals or necessarily to reflect the prices at which companies may actually be sold. Because these estimates are inherently subject to uncertainty, none of NYSE Group, Euronext, the NYSE Group board of directors, Citigroup or any other person assumes responsibility if future results or actual values differ materially from the estimates. Citigroup's analyses were prepared solely as part of Citigroup's analysis of the fairness of the consideration to be issued by NYSE Euronext for the acquisition of the Euronext shares and were provided for the information of the NYSE Group board of directors in that connection. The opinion of Citigroup was only one of the factors taken into consideration by the NYSE Group board of directors in making its determination to approve the transaction agreement and the transactions. See "The Combination—NYSE Group's Reasons for the Combination."

Citigroup is an internationally recognized investment banking firm engaged in, among other things, the valuation of businesses and their securities in connection with mergers and acquisitions, restructurings, leveraged buyouts, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. The NYSE Group board of directors selected Citigroup to act as its financial advisor in connection with the proposed transaction with Euronext on the basis of Citigroup's international reputation, Citigroup's experience in the financial service industry and Citigroup's familiarity with NYSE Group and Euronext. Pursuant to its May 17, 2006 engagement letter between NYSE Group and Citigroup, NYSE Group paid Citigroup $5 million following the delivery of its opinion, and NYSE Group has agreed to pay Citigroup an additional fee of $10 million upon the closing of the exchange offer, and a fee of $20 million (less any fees previously paid to Citigroup under its engagement letter with NYSE Group) upon the completion of any second-step transaction that results in a minimum of 95% ownership in Euronext by NYSE Euronext or a company formed by NYSE Euronext for the purpose of acquiring Euronext. NYSE Group has also agreed to indemnify Citigroup against specific liabilities and expenses relating to or arising out of its engagement, including liabilities under the federal securities laws. Citigroup and its affiliates in the past have provided services to NYSE Group unrelated to the proposed transactions, for which services Citigroup and its affiliates have received compensation, including, without limitation, acting as financial advisor, and providing a fairness opinion in 2005, to the New York Stock Exchange, Inc. in connection with its merger with Archipelago Holdings, Inc. and acting as co-manager with respect to the offering of 28,750,000 shares of NYSE Group common stock by stockholders of NYSE Group in May 2006. In addition:

•: Shares of Citigroup Inc., the parent company of Citigroup, are listed on the NYSE and, accordingly, Citigroup Inc. pays listing fees to the NYSE. In addition, certain current and former officers of Citigroup and its affiliates have in the past served on the board of directors of the NYSE and certain employees of Citigroup and its affiliates serve on various NYSE committees.
•: Citigroup and its affiliates are collectively a leading trader of NYSE stocks and maintain a trading operation on the NYSE floor.
•: John Reed, Citigroup Inc.'s former chairman and co-chief executive officer, is a former chairman and chief executive officer of the NYSE. In addition, Richard Ketchum, former general counsel of Citigroup, is the chief executive officer of NYSE Regulation.

received fees in connection therewith, including advising NYSE Arca Holdings, Inc. (then known as PCX Holdings, Inc.), the parent of NYSE Arca, in its sale to Archipelago. In addition, Citigroup holds Equity Trading Permits ("ETPs") and Options Trading Permits (or "OTPs") issued by NYSE Arca and, accordingly, is subject to its regulatory oversight. Certain current and former employees of Citigroup and its affiliates have in the past served and are currently serving on the NYSE Arca board of directors.

•: Citigroup is a NYSE member organization and, accordingly, is subject to the regulatory oversight of the NYSE.
•: Citigroup Global Markets Limited, an affiliate of Citigroup ("CGML"), is a member of, and conducts securities trading through the exchanges of, certain of Euronext's affiliates, including Euronext Amsterdam, Euronext Paris, Euronext.liffe and MTS European Bond Trading, and accordingly, is subject to the regulatory oversight of such exchanges. CGML also holds equity positions in certain of these exchanges in connection with its membership in such exchanges.
•: In the ordinary course of business, Citigroup and its affiliates may actively trade or hold the securities of NYSE Group and Euronext for their own account or for the account of their customers and, accordingly, may at any time hold a long or short position in such securities. As of June 1, 2006, Citigroup held for its own account approximately 637,576 shares of NYSE Group common stock and approximately 191,000 Euronext shares, representing approximately 0.4% and 0.17% of the outstanding shares of NYSE Group and Euronext, respectively. In addition, Citigroup and its affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with NYSE Group, Euronext and their respective affiliates and companies in which they may have an investment.

Opinions of Euronext's Financial Advisors

In arriving at its opinion, Morgan Stanley assumed and relied upon without independent verification the accuracy and completeness of the information reviewed by Morgan Stanley for the purposes of its opinion. With respect to the financial projections, including in relation to strategic, financial and operational benefits expected to be realized from the combination, Morgan Stanley assumed that they were reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of Euronext and of NYSE Group. In addition, Morgan Stanley assumed that the combination would be consummated in accordance with the terms set forth in the combination agreement, and that in connection with the receipt of all necessary anti-trust and regulatory approvals for the combination, no restrictions would be imposed that would have a material adverse effect on the contemplated benefits expected to be derived from the combination. Morgan Stanley did not make any independent valuation or appraisal of the assets or liabilities of Euronext or NYSE Group, and Morgan Stanley was not furnished with any such appraisals. Morgan Stanley is not a legal, tax, or regulatory expert, and Morgan Stanley relied upon, without independent verification, the assessments of such experts with respect to such issues. Morgan Stanley's opinion was necessarily based on economic, market and other conditions as in effect on, and the information made available to Morgan Stanley as of, June 1, 2006. Events occurring after June 1, 2006, may affect Morgan Stanley's opinion and the assumptions used in preparing it, and Morgan Stanley did not assume any obligation to update, revise or reaffirm its opinion.

Morgan Stanley is an internationally recognized investment banking and advisory firm. Morgan Stanley, as part of its investment banking and financial advisory business, is continuously engaged in the

valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. In the ordinary course of business, Morgan Stanley may from time to time trade in the securities, indebtedness, commodities or currencies or derivatives thereof, of Euronext and NYSE Group for its own account, the accounts of investment funds and other clients under the management of Morgan Stanley and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such instruments for any such account.

In connection with the financial advisory services provided to Euronext relating to the merger, Euronext has agreed to pay Morgan Stanley a customary fee, a substantial portion of which is due upon completion of the combination. Euronext has also agreed to reimburse Morgan Stanley for its expenses incurred in performing its services and to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities under federal securities laws, related to or arising out of Morgan Stanley's engagement and any related transactions. In the past, Morgan Stanley and its affiliates have provided financial advisory and financing services for Euronext and NYSE Group and have received fees in connection with such services. Additionally, Morgan Stanley and its affiliates route order flow in equity securities to the NYSE and NYSE Arca, and execute trades through Euronext. Morgan Stanley is an NYSE member organization and, accordingly, is subject to the regulatory oversight of the NYSE. The common stock of Morgan Stanley also is listed for trading on the NYSE.

Opinion of ABN AMRO

In connection with the combination, the Euronext managing and supervisory boards retained ABN AMRO to act as their financial advisor and to render an opinion as to whether the standard offer consideration to be offered to Euronext shareholders in the exchange offer is fair, from a financial point of view, to the Euronext shareholders. The Euronext managing and supervisory boards selected ABN AMRO to act as their financial advisor based on ABN AMRO's qualifications, expertise and reputation and its knowledge of the business and affairs of Euronext. On June 1, 2006, ABN AMRO delivered its written opinion to the Euronext managing and supervisory boards that, as of that date, and based upon and subject to the assumptions, qualifications and other considerations set forth in the ABN AMRO opinion, the standard offer consideration to be offered to the Euronext shareholders in the exchange offer was fair from a financial point of view to the Euronext shareholders.

The full text of the ABN AMRO opinion is attached hereto as Annex D and sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by ABN AMRO in rendering its opinion. ABN AMRO provided its opinion to the Euronext managing and supervisory boards in connection with their evaluation of the combination. ABN AMRO's opinion is directed to the Euronext managing and supervisory boards and addresses only the fairness from a financial point of view of the standard offer consideration to be offered to the Euronext shareholders in the exchange offer, and does not address any other aspect of the combination, including the relative merits of the combination compared to other strategic alternatives potentially available to Euronext, the relative effects of any potential alternative transaction in which Euronext might have engaged or the Euronext managing and supervisory boards' decisions to proceed with the combination. The ABN AMRO opinion does not constitute a recommendation to any Euronext shareholder as to whether such shareholders should approve the combination agreement and the transactions contemplated thereby or whether such shareholders should tender their shares in the exchange offer or otherwise act in connection with the combination, or to any NYSE Group stockholders as to whether such stockholders should accept or reject the combination agreement and the transactions contemplated thereby or tender their shares in the exchange offer or otherwise act in connection with the combination. This summary does not purport to be a complete description of the ABN AMRO opinion or the analyses performed by ABN AMRO in connection with rendering its opinion and is qualified in its entirety by reference to the written

opinion of ABN AMRO set forth in Annex D hereto. You are urged to read the opinion carefully and in its entirety.

For the purposes of providing its opinion, ABN AMRO:

•: reviewed certain publicly available business and financial information relating to Euronext, including Euronext's audited consolidated financial statements for the three consecutive financial years ended December 31, 2005, 2004 and 2003 and the unaudited quarterly figures for the three months ended March 31, 2006 and certain publicly available financial forecasts relating to the business and financial prospects of Euronext prepared by certain research analysts;
•: reviewed certain publicly available business and financial information relating to NYSE Group, including NYSE Group's unaudited pro forma condensed combined financial data for the financial year ended December 31, 2005 (Form S-1 dated April 13, 2006, as amended through May 2006) and the unaudited quarterly figures for the three months ended March 31, 2006 and certain publicly available financial forecasts relating to the business and financial prospects of NYSE Group prepared by certain research analysts;
•: reviewed NYSE Group's specific regulatory filings with regard to its merger with Archipelago (Joint Proxy Statement / Prospectus on Form S-3, dated November 3, 2005, as further supplemented and amended pursuant to the Supplement dated November 23, 2005) and secondary offering (Form S-1 dated April 13, 2006, as amended through May 4, 2006) and the business plan of the NYSE Group which was provided to ABN AMRO by NYSE Group's advisers;
•: participated in discussions with and reviewed information provided by the senior management of Euronext and NYSE Group with respect to the businesses and prospects of Euronext and NYSE Group;
•: participated in discussions with, and reviewed information provided by, relevant employees of Euronext and NYSE Group with regard to the expected synergies which a combination of Euronext and NYSE Group is expected to generate;
•: reviewed the historical stock prices and trading volumes of the Euronext shares and the NYSE Group shares;
•: reviewed the financial terms of certain transactions that ABN AMRO believed to be comparable to the exchange offer;
•: reviewed public information with respect to certain other companies ABN AMRO believed to be comparable to Euronext and NYSE Group;
•: reviewed those parts of the combination agreement and other documents, that ABN AMRO deemed relevant for the purposes of providing its opinion; and
•: performed such other financial reviews and analysis, as ABN AMRO, in its absolute discretion, deemed appropriate.

AMRO or used by ABN AMRO, assumed that the same were not misleading and did not assume or accept any liability or responsibility for any independent verification of such information or any independent valuation or appraisal of any of the assets, operations or liabilities of Euronext or NYSE Group, nor was ABN AMRO provided with any such valuation or appraisal. In preparing its opinion, ABN AMRO received specific confirmation from senior management of Euronext that the assumptions specified above were reasonable and no information had been withheld from ABN AMRO that could have influenced the purport of its opinion or the assumptions on which it was based. ABN AMRO did not seek or obtain such confirmation from NYSE Group.

Further, ABN AMRO's opinion was necessarily based on financial, economic, monetary, exchange rate, market and other conditions, as in effect on, and the information made available to ABN AMRO or used by it up to, the date of the ABN AMRO opinion. The ABN AMRO opinion focused exclusively on whether the standard offer consideration to be offered to Euronext shareholders in the exchange offer was fair from a financial point of view to the Euronext shareholders and did not address any other issues, such as the underlying business decision to agree to a business combination between Euronext and NYSE Group or the commercial merits of the foregoing, which are matters solely for the supervisory board and the managing board of Euronext. In addition, the ABN AMRO opinion did not in any manner address the prices or volumes at which the Euronext shares, the NYSE Euronext shares, the NYSE Group shares or the shares of any other entities involved in the transactions contemplated by the combination agreement, may trade following consummation of the exchange offer or the combination. Subsequent developments in the aforementioned and other conditions may affect the conclusions expressed in the ABN AMRO opinion and the assumptions made in preparing the ABN AMRO opinion and ABN AMRO is not obliged to update, revise or reaffirm the ABN AMRO opinion if such conditions change.

In rendering its opinion, ABN AMRO did not provide legal, regulatory, tax, accounting or actuarial advice and accordingly ABN AMRO did not, and does not, assume any responsibility or liability in respect thereof. Furthermore, ABN AMRO assumed that the exchange offer and the other transactions contemplated by the combination agreement would be consummated on the terms and conditions as set out in the draft of the combination agreement it reviewed, without any changes to or waiver of their terms or conditions, in compliance with law and without the exercise of any appraisal rights, and that all requisite consents and approvals would be obtained. ABN AMRO also assumed that debt financing for the cash portion of the consideration to be offered in the exchange offer is available and ABN AMRO expressed no opinion on the price, terms or form of such financing.

ABN AMRO was selected by the Euronext managing and supervisory boards as their financial advisor, and to render an opinion to the Euronext managing and supervisory boards, because ABN AMRO is an internationally recognized investment banking firm and because, as part of its investment banking business, ABN AMRO is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. ABN AMRO is acting as financial advisor to Euronext in connection with the combination and the transactions contemplated by the combination agreement and will receive fees for its services, a significant portion of which fees are contingent upon consummation of the combination. From time to time, ABN AMRO and its affiliates may have also (i) maintained banking and financial advisory relationships with Euronext or NYSE Group, and (ii) executed transactions, for their own account or for the accounts of customers, in the Euronext shares or the NYSE Group shares or debt securities of Euronext or NYSE Group and, accordingly, may at any time hold a long or short position in such securities. ABN AMRO is a holder of Euronext shares and NYSE Group shares, and provides financing facilities to Euronext. ABN AMRO may in the future provide certain banking, financial advisory or financing services to, and execute transactions for its own account or for the accounts of our customers in the securities of, Euronext, the NYSE Group or NYSE Euronext. In addition, ABN AMRO's ordinary shares are traded on Euronext Amsterdam and ABN AMRO's American Depositary Shares are listed on the NYSE. ABN AMRO Incorporated, an affiliate of ABN AMRO, is an NYSE member organization and is subject to the regulatory oversight of the NYSE.

101

Pursuant to a letter agreement, Euronext has agreed to pay certain customary fees to ABN AMRO for its financial advisory services provided in connection with the combination, a substantial portion of which is due upon consummation of the combination. Regardless of whether a transaction is proposed or completed, Euronext has agreed to reimburse ABN AMRO, immediately upon ABN AMRO's request, for all reasonable out-of-pocket expenses, including reasonable fees and disbursements of ABN AMRO's counsel, and has agreed to indemnify ABN AMRO against certain liabilities, including liabilities under the federal securities laws. The terms of the fee arrangement with ABN AMRO, which are customary in transactions of this nature, were negotiated at arm's length between Euronext and ABN AMRO, and the Euronext managing board and supervisory board were aware of such arrangement, including the fact that a significant portion of the aggregate fee payable to ABN AMRO is contingent upon consummation of the transaction.

Summary of Financial Analyses

In preparing their respective opinions to the Euronext managing and supervisory boards, Morgan Stanley and ABN AMRO performed a variety of financial and comparative analyses, including those described below. The summary of the analyses described below is not a complete description of the analyses underlying their opinions. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at their respective opinions, each of Morgan Stanley and ABN AMRO made qualitative judgments as to the significance and relevance of each analysis and factor that they considered and each of Morgan Stanley and ABN AMRO considered the results of all of their analyses as a whole and did not attribute any particular weight to any analysis or factor considered. Accordingly, each of Morgan Stanley and ABN AMRO believe that the summary provided and the analyses described below must be considered as a whole and that selecting any portion of these analyses, without considering all of them as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, each of Morgan Stanley and ABN AMRO may have given various analyses and factors more or less weight than other analyses and factors and may have deemed various assumptions more or less probable than other assumptions, so that the range of valuations resulting from any particular analysis or combination of analyses described below should therefore not be taken to be either Morgan Stanley's or ABN AMRO's view of the actual value of Euronext and NYSE Group.

In their analyses, each of Morgan Stanley and ABN AMRO made numerous assumptions with respect to industry performance, general business and economic conditions and other matters. Many of these assumptions are beyond the control of Euronext and NYSE Group. Any estimates contained in Morgan Stanley's and ABN AMRO's analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by these estimates. The analyses described below were prepared solely as a part of Morgan Stanley's analysis of the fairness from a financial point of view of the consideration to be received by the Euronext shareholders in the exchange offer and in connection with the delivery by Morgan Stanley of its opinion dated June 1, 2006 to the Euronext managing and supervisory boards, and ABN AMRO's analysis of the fairness from a financial point of view of the standard offer consideration to be offered to Euronext shareholders in the exchange offer and in connection with the delivery by ABN AMRO of its opinion dated June 1, 2006 to the Euronext managing and supervisory boards. Morgan Stanley's and ABN AMRO's analyses do not purport to be appraisals or to reflect the prices at which Euronext shares, shares of NYSE Group common stock or shares of NYSE Euronext common stock might actually trade. The consideration to be received by Euronext shareholders in the combination was determined through arm's-length negotiations between Euronext and NYSE Group and the Euronext managing and supervisory boards authorized Euronext's entry into the combination agreement. Neither Morgan Stanley nor ABN AMRO recommended any consideration to Euronext or that any given exchange offer consideration constituted the only appropriate consideration for the combination.

102

In addition, Morgan Stanley's and ABN AMRO's respective opinions and their joint presentation to the Euronext managing and supervisory boards was one of many factors taken into consideration by Euronext's managing and supervisory boards in deciding to approve the combination. Consequently, the analyses as described below should not be viewed as determinative of the decision of the Euronext managing and supervisory boards with respect to the combination or of whether the Euronext managing and supervisory boards would have been willing to agree to a different transaction.

The following is a summary of the material financial analyses of Morgan Stanley and ABN AMRO which were reviewed with the Euronext managing and supervisory boards on June 1, 2006. These summaries of financial analyses include information presented in tabular format. To fully understand Morgan Stanley's and ABN AMRO's financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

52-week Common Stock Trading Range for Euronext and NYSE Group

Morgan Stanley and ABN AMRO analyzed the historical closing prices and trading volumes for Euronext shares for the period from May 31, 2005 to May 30, 2006. During that time, the lowest closing price for Euronext shares was €26.66 per share and the highest closing price was €77.95 per share. Morgan Stanley and ABN AMRO noted that Euronext shares closed at a price of €66.10 per share on May 30, 2006. Morgan Stanley and ABN AMRO also noted that the implied purchase price of Euronext shares, based on the closing prices of NYSE Group common stock and Euronext shares on May 30, 2006 and the proposed exchange offer consideration, was €65.61 per share and was near Euronext's closing price as of May 30, 2006.

Morgan Stanley and ABN AMRO also analyzed the historical closing prices and trading volumes for NYSE Group common stock for the period from March 8, 2006 to May 30, 2006. During that time, the lowest closing price for NYSE Group common stock was $56.80 per share and the highest closing price was $87.53.

Analyst Price Targets

Morgan Stanley and ABN AMRO reviewed and analyzed future public market trading price targets for Euronext shares and NYSE Group common stock prepared and published by equity research analysts, for the period of March 20, 2006 to May 26, 2006. For these reports, the analyst price targets yielded an average valuation of Euronext shares of €76.45 and an average valuation of NYSE Group common stock of $59.00.

The public market trading price targets published by securities research analysts do not necessarily reflect current market trading prices for Euronext shares and NYSE Group common stock and these estimates are subject to uncertainties, including the future financial performances of Euronext and NYSE Group and future financial market conditions.

Comparable Companies Analysis

While noting that no comparable public company is exactly identical to Euronext or NYSE Group, Morgan Stanley and ABN AMRO compared selected financial information for Euronext and NYSE Group with publicly available consensus earnings estimates for comparable companies. These companies were selected based on their product offerings, business profiles and operating processes. Each of these companies operates in the financial exchange industry and demonstrates operating and business characteristics similar to those of Euronext and NYSE Group. Based upon publicly available estimates of certain securities research analysts and using the closing prices as of May 30, 2006, Morgan Stanley and ABN AMRO calculated, for each of these companies, the stock trading price divided by the earnings per share estimates for calendar years 2006 and 2007 (the "price/earnings" multiple).

103

Using a 2006 price/earnings multiple range between 20.0x and 24.0x implied a Euronext share price between €56.08 and €67.29 per share.

Using a 2007 price/earnings multiple range between 17.5x and 21.5x implied a Euronext share price between €55.17 and €67.78 per share. The closing price of Euronext shares was €66.10 per share on May 30, 2006.

Using a 2007 price/earnings multiple range between 24.0x and 28.0x implied a NYSE Group common stock price between $53.44 and $62.35 per share. The closing price of NYSE Group common stock was $58.25 per share on May 30, 2006.

No company included in the comparable company analysis is identical to Euronext or NYSE Group. In evaluating the comparable companies, Morgan Stanley and ABN AMRO made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters. Many of these matters are beyond the control of Euronext or NYSE Group, such as the impact of competition on the business of Euronext or NYSE Group and the industry in general, industry growth and the absence of any material adverse change in the financial condition and prospects of Euronext or NYSE Group or the industry or in the financial markets in general. Mathematical analysis, such as determining the average or median, is not necessarily in itself a meaningful method of using comparable company data.

Comparable Transactions Analysis

Morgan Stanley and ABN AMRO also analyzed the ratio of equity value, defined as market capitalization, to estimated next twelve month net income, of 13 selected transactions in the exchange sector since 1997 and the implied value per Euronext share based on a range of multiples.

The following table summarizes Morgan Stanley's and ABN AMRO's analysis:

Precedent Transaction Financial Statistics		Euronext Financial Statistic		Comparable Transactions Multiple Statistic		Implied Value Per Share Range for Euronext
Equity Value to Estimated Next Twelve Months Net Income		€320MM		25.0-30.0x		€70.09-84.11

No company or transaction utilized in the precedent transaction analyses is identical to Euronext or the combination. In evaluating the precedent transactions, Morgan Stanley and ABN AMRO made judgments and assumptions with regard to general business, market and financial conditions and other matters, which are beyond the control of Euronext and NYSE Group, such as the impact of competition on the business of Euronext, NYSE Group or the industry generally, industry growth and the absence of any adverse material change in the financial condition of Euronext, NYSE Group, or the industry or in the financial markets in general, which could affect the public trading value of the companies and the aggregate value of the transactions to which they are being compared.

Discounted Cash Flow Analysis

Morgan Stanley and ABN AMRO performed a discounted cash flow analysis for each of Euronext and NYSE Group. The financial information used to complete this analysis was based on financial projections provided to Morgan Stanley and ABN AMRO by the management of Euronext and NYSE Group, respectively. In each case, Morgan Stanley and ABN AMRO calculated the present value of the unlevered free cash flows for the period beginning June 1, 2006 and ending on December 31, 2009. Morgan Stanley and ABN AMRO added to this amount the present value of a "terminal value," an amount calculated by dividing the company's projected free cash flow for 2010 by the weighted average cost of capital ("WACC") minus a perpetual growth rate. Morgan Stanley and ABN AMRO calculated terminal

104

values for Euronext by utilizing a WACC of 7.9% and perpetual growth rate ranges of 2.5% to 3.5% and calculated terminal values for NYSE Group by utilizing a WACC of 9.0% and perpetual growth rate ranges of 2.5% to 3.5%. For purposes of this analysis Morgan Stanley and ABN AMRO believed the discount rates provided a reasonable estimate of each of Euronext's and NYSE Group's cost of capital. For purposes of this analysis, Morgan Stanley and ABN AMRO used a 29.1% statutory tax rate for Euronext and 43% for NYSE Group. The following table summarizes the results of this analysis:

		Perpetual Growth Rate Ranges
Discounted Cash Flow Analysis—Price Per Share		2.5	%	3.5	%
Euronext Range: 7.9% WACC		€66.19		€75.67

		Perpetual Growth Rate Ranges
Discounted Cash Flow Analysis—Price Per Share			2.5	%		3.5	%
NYSE Group Range: 9.0% WACC		$	67.24		$	74.73

Assessed Ranges

Based on the above financial analyses, Morgan Stanley and ABN AMRO selected a representative range of values per Euronext share and per NYSE Group share. These assessed ranges were between €63.00 and €73.00 per Euronext share (or between €60.00 and €70.00 per Euronext share, excluding payment by Euronext to its shareholders of a €3.00 per share capital distribution), and between $58.00 and $68.00 per NYSE Group share.

Interests of Officers and Directors in the Combination

Interests of the NYSE Group Directors and Executive Officers

In considering approval by the NYSE Group board of directors of the combination agreement, NYSE Group stockholders should be aware that members of the NYSE Group board of directors and its executive management have relationships, agreements or arrangements that provide them with interests in the combination that may be in addition to or different from those of the NYSE Group stockholders. The NYSE Group board of directors was aware of these relationships, agreements and arrangements during its deliberations on the merits of the combination. See "The Combination—NYSE Group's Reasons for the Combination."

NYSE Euronext Directors. Pursuant to the terms of the combination agreement, all of the directors of NYSE Group immediately prior to the combination (including John A. Thain, the chief executive officer of the NYSE Group and Marshall N. Carter, the chairman of NYSE Group) will be among the initial directors of the NYSE Euronext board of directors after the combination. The current NYSE Group directors (other than John A. Thain) who are expected to serve on the NYSE Euronext board of directors following the combination are expected to be compensated for their services in that capacity in accordance with a customary director compensation policy. For further information, see "Directors and Management of NYSE Euronext After the Combination—Compensation of Directors and Executive Officers."

NYSE Euronext Management. As of the completion of the combination, NYSE Euronext will be managed by a management committee consisting of up to 16 members, including an equal number of NYSE Group designees and Euronext designees. The committee will include, among others, the chief executive officer of NYSE Group as of immediately prior to the combination (who will be the chief executive officer of NYSE Euronext) and the chief executive officer of Euronext as of immediately prior to the combination (who will be the deputy chief executive officer of NYSE Euronext).

105

NYSE Group Equity Compensation Awards. In the merger, all stock options to acquire NYSE Group common stock, including those held by directors and executive officers, will be converted into options to acquire an equal number of shares of NYSE Euronext common stock at the same per share exercise price, and all NYSE Group restricted stock units, including those held by directors and executive officers, will be converted into the same number of NYSE Euronext restricted stock units.

Indemnification and Insurance. The combination agreement provides that, upon completion of the combination, NYSE Euronext will, to the fullest extent permitted by law, indemnify and hold harmless, and provide advancement of expenses to, all past and present directors, officers and employees of NYSE Group and its subsidiaries to the same extent those individuals were entitled to indemnification or advancement of expenses under the NYSE Group certificate of incorporation, bylaws and indemnification agreements. To this end, the NYSE Euronext certificate of incorporation and bylaws will include provisions relating to indemnification of officers, directors and employees that are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions in the current NYSE Group certificate of incorporation and bylaws.

The combination agreement also provides that NYSE Euronext will maintain for a period of six years after completion of the combination the current directors' and officers' liability insurance policies maintained by NYSE Group, or policies with the same coverage and containing terms and conditions that are no less advantageous to the insured in the aggregate, with respect to claims arising from facts or events that occurred on or before the completion of the combination, although NYSE Euronext will not be required to make annual premium payments in excess of 250% of the annual premiums currently paid by NYSE Group for directors' and officers' liability insurance. Instead, NYSE Group may, at its option, purchase a six-year "tail" prepaid policy on the same terms and conditions and subject to the same annual premium expenditure limitation.

Interests of Euronext Directors and Executive Officers

In considering the approval by the Euronext supervisory and managing boards of the combination agreement, the Euronext stockholders should be aware that members of these boards and Euronext's executive management have relationships, agreements or arrangements that provide them with interests in the combination that may be in addition to or different from those of the Euronext shareholders. The Euronext supervisory and managing boards were aware of these relationships, agreements and arrangements during their deliberations on the merits of the combination. See "The Combination—Euronext's Reasons for the Combination."

NYSE Euronext Directors. Pursuant to the terms of the combination agreement, the NYSE Euronext board of directors will include the chairman of the Euronext supervisory board as of immediately prior to the combination (Jan-Michiel Hessels, who is expected to be the chairman of the NYSE Euronext board of directors), the chief executive officer of Euronext as of immediately prior to the combination (Jean-François Théodore, who is expected to be deputy chief executive officer of NYSE Euronext), and 8 other individuals who were members of the Euronext supervisory board as of immediately prior to the combination. For further information, see "Directors and Management of NYSE Euronext After the Combination—Compensation of Directors and Executive Officers."

NYSE Euronext Management. As of the completion of the combination, NYSE Euronext will be managed by a management committee consisting of up to 16 members, including an equal number of NYSE Group designees and Euronext designees. The committee will include, among others, the chief executive officer of Euronext as of immediately prior to the completion of the combination (who will be the deputy chief executive officer of NYSE Euronext) and the chief executive officer of NYSE Group as of immediately prior to the combination (who will be the chief executive officer of NYSE Euronext).

106

Indemnification and Insurance. The combination agreement provides that, upon completion of the combination, NYSE Euronext will, to the fullest extent permitted by law, indemnify and hold harmless, and provide advancement of expenses to, all past and present directors, officers and employees of Euronext and its subsidiaries to the same extent those individuals were entitled to indemnification or advancement of expenses under the Euronext articles of association and indemnification agreements. To this end, the NYSE Euronext certificate of incorporation and bylaws will include provisions relating to indemnification of officers, directors and employees that are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions in the current Euronext articles of association.

The combination agreement also provides that NYSE Euronext will maintain for a period of six years after completion of the combination the current directors' and officers' liability insurance policies maintained by Euronext, or policies with the same coverage and containing terms and conditions that are no less advantageous to the insured in the aggregate, with respect to claims arising from facts or events that occurred on or before the completion of the combination, although NYSE Euronext will not be required to make annual premium payments in excess of 250% of the annual premiums currently paid by Euronext for directors' and officers' liability insurance. Instead, Euronext may, at its option, purchase a six-year "tail" prepaid policy on the same terms and conditions and subject to the same annual premium expenditure limitation.

The Delaware Trust and the Dutch Foundation

Generally

NYSE Euronext will operate several regulated entities located in the United States and in various jurisdictions in Europe. In connection with obtaining regulatory approval of the combination, NYSE Euronext intends, subject to the approval of its regulatory authorities, to implement certain special arrangements consisting of two standby structures, one involving a Dutch foundation (stichting) and one involving a Delaware trust. The Dutch foundation will be empowered to take actions to mitigate the effects of any material adverse change in U.S. law that has an "extraterritorial" impact on non-U.S. issuers listed on Euronext markets, non-U.S. financial services firms that are members of Euronext markets or holders of exchange licenses with respect to the Euronext markets. The Delaware trust will be empowered to take actions to mitigate the effects of any material adverse change in European law that has an "extraterritorial" impact on the non-European issuers listed on the NYSE Group securities market non-European financial services firms that are members of any NYSE Group securities market or holders of exchange licenses with respect to the NYSE Group securities exchanges.

Administration of the Foundation and of the Trust

Each of the foundation and the trust will be administered by a board of three directors, each of whom shall satisfy specific eligibility requirements. The majority of the directors of the foundation will be European domiciliaries. The majority of the directors of the trust will be U.S. domiciliaries.

Terms of appointment for the directors of each of the foundation and the trust will be three years for the first three terms with one-year terms thereafter, with no limit on the total number of terms a director may serve.

The initial directors of the trust and of the foundation will be selected jointly by NYSE Group and Euronext prior to the combination, with successor members to be selected by the nominating and governance committee of NYSE Euronext. Directors of the foundation and the trust may only be removed for cause by the governance and nominating committee of NYSE Euronext.

Actions of the foundation and the trust shall be taken in the best interest of NYSE Euronext and will require unanimous approval of the members of the relevant board of directors, following reasonable consultation and good-faith cooperation with NYSE Euronext. The foregoing, however, shall not limit or

107

affect the obligations of the directors in regard to their assessment of whether there has been a material adverse change of law (as described below) or, if such change has occurred, whether the same is continuing.

Material Adverse Change in Law

With respect to Euronext and the Dutch foundation, a material adverse change in law means the enactment of a new U.S. law (including the enactment of a new law that amends an existing law and including the enactment or adoption of regulations implementing any such new law or, if applicable, regulations amending or replacing regulations implementing any such new law) having a material adverse effect (including as may result from an increase in the regulatory burden that may occur as a result of such law) on:

•

a substantial proportion of the non-U.S. issuers listed on a Euronext market solely because:

•: the securities of such non-U.S. issuers are listed on such Euronext market; and
•: such Euronext market is owned directly or indirectly by NYSE Euronext (it being understood that if non-U.S. issuers can avoid such material adverse effect by complying with Rule 12g3-2(b) under the Exchange Act, as currently in effect, or a provision not materially more burdensome, then such U.S. laws shall not be deemed to have a material adverse effect on non-U.S. issuers);

•

a substantial proportion of the non-U.S. financial services firms that are members of any Euronext market solely because:

•: such non-U.S. financial services firms are members of such Euronext market (and such firm is not a member of, and does not do business on, a NYSE market or other U.S. market); and
•: such Euronext market is owned directly or indirectly by NYSE Euronext; or

•

any holder of an exchange license for a Euronext market in a manner that has a material adverse effect on such market

in each case, to the extent that the object of such new law is to regulate the market operating rules, listing standards, or member financial services firm rules (for such firms that are not members of, and do not do business on, a NYSE market or other U.S. market), solely because (i) such holder operates a Euronext market and (ii) such Euronext market is owned directly or indirectly by NYSE Euronext.

With respect to NYSE Group and the Delaware trust, a material adverse change in law means the enactment of a new European law (including the enactment of a new law that amends an existing law and including the enactment or adoption of regulations implementing any such new law or, if applicable, regulations amending or replacing regulations implementing any such new law) having a material adverse effect (including as may result from an increase in the regulatory burden that may occur as a result of such law) on:

•

a substantial proportion of the non-U.S. issuers listed on a NYSE Group securities exchange solely because:

•: the securities of such non-U.S. issuers are listed on such NYSE Group securities exchange and
•: such NYSE Group securities exchange is owned directly or indirectly by NYSE Euronext;

108

•

a substantial proportion of the non-U.S. financial services firms of any NYSE Group securities exchange solely because:

•: such non-U.S. financial services firms are members of such NYSE Group securities exchange (and such firm is not a member of, and does not do business on, a Euronext market or other securities market in Europe) and
•: such NYSE Group securities exchange is owned directly or indirectly by NYSE Euronext; or

•

any holder of an exchange license for a NYSE Group securities exchange in a manner that has a material adverse effect on such market,

in each case, to the extent the object of such law is to regulate the market operating rules, listing standards, or member financial services firm rules (for such firms that are not members of, and do not do business on, a Euronext market or other European market), solely because (i) such holder operates a NYSE Group securities exchange and (ii) such NYSE Group securities exchange is owned directly or indirectly by NYSE Euronext.

However, in either case, a material adverse change of law shall not be deemed to have occurred with respect to any U.S. or European law, as applicable, if such law is not (and for so long as it is not) effective, enforceable or applicable by reason of any permanent or temporary injunction, order or other administrative relief, or that is not self-effectuating in the absence of implementing regulations that have not yet been adopted.

Remedies of the Dutch Foundation and Delaware Trust

Upon the occurrence of a material adverse change in law that shall continue, where applicable, after the cure periods specified below, the board of trustees of the Delaware trust, or the board of directors of the Dutch foundation, as applicable, may exercise the following remedies following prior notice to, and, if required under then applicable laws, prior approval by, the European regulators having jurisdiction over Euronext or its regulated subsidiaries or the SEC, as applicable:

•: the delivery of confidential or public and non-binding or binding advice to Euronext or NYSE Group, as applicable, and NYSE Euronext;
•: after a cure period of six months, the assumption of certain limited management responsibilities of NYSE Group or its subsidiaries or Euronext or its subsidiaries, as applicable;
•: after a cure period of twelve months, the exercise of a call option on priority shares or preference shares which hold special approval or initiative rights on certain matters with respect to NYSE Group, Euronext, or any of their subsidiaries, to be specified in writing by the holder of the priority shares or preference shares to the board(s) of Euronext or NYSE Group, as applicable, and relating to (i) changes to the Rule Books of the relevant market or securities exchange, (ii) decisions to enter into (or not enter into) or alter the terms of listing agreements of the relevant market or securities exchange, (iii) decisions to enter into (or not enter into) or alter the terms of contractual arrangements with any non-U.S. or non-European, as applicable, financial services firms (members, brokers-dealers) in relation to the European or U.S. markets, respectively, (iv) changes in ICT for the relevant markets or securities exchanges, and (v) changes in clearing and settlement for the relevant market or securities exchanges, as applicable, and
•: after a cure period of twelve months, the exercise of a call option on a majority of the ordinary or common shares of NYSE Group, Euronext or any of their respective subsidiaries.

Furthermore, subject to any required approval by the European regulators having jurisdiction over Euronext or its regulated subsidiaries or the SEC (as applicable), the Dutch foundation or the Delaware trust shall be entitled to give confidential non-binding advice to NYSE Euronext at any time before the

109

end of the above-mentioned cure period and NYSE Euronext shall be entitled, in its sole discretion, to implement any remedy at any time before the end of such cure period.

Any of the above remedies may be imposed only if and to the extent that such remedy (i) mitigates the effects of any change in law so that such change ceases to be a material adverse change of law and (ii) is the least intrusive remedy available. In determining whether a remedy is the least intrusive:

•: negative control by the foundation or trust shall be preferred over affirmative control by foundation or trust;
•: authority of the foundation or trust shall be asserted over the fewest and most narrow decisions of NYSE Euronext and its subsidiaries (for example, authority over listing standards shall be preferred to authority over the election of directors); and
•: local remedies (such as the exercise of voting rights on the shares of a subsidiary of NYSE Euronext operating an exchange that is affected by the material adverse change of law) shall be preferred to global remedies (such as the exercise of voting rights of Euronext or NYSE Group).

In addition, prior to the exercise of a call option, the board of directors of the foundation or the board of trustees of the trust, as applicable, must first:

•: determine that no other remedy can mitigate the effect of the material adverse change of law; and
•: consult with the board of directors of NYSE Euronext and with (y) the supervisory and managing boards of Euronext and the applicable European regulators with authority over the affected exchange or (z) the board of directors of NYSE Group and the SEC, as applicable, to consider the solutions available to address the situation that has arisen and would trigger the right of the foundation or trust, as applicable, to exercise one of the remedies described above, taking into account any possible adverse consequences for NYSE Euronext and NYSE Group or NYSE Euronext, as applicable, in terms of taxation or accounting treatment, in each case acting in the best interests of NYSE Euronext.

In the event a call option is exercised, the Dutch foundation or the Delaware trust, as applicable, will issue to NYSE Euronext certificates representing the economic rights of any shares acquired pursuant to such option exercise.

Unwinding of Remedies

If and when any of the conditions of a material adverse change of law cease, any and all remedies shall be immediately unwound.

Additionally, NYSE Euronext shall have the right, at any time and regardless of whether a change of law continues to be a material adverse change of law, to cause the unwinding of any remedy for the purpose of and to the extent necessary to effect a divesture or spin-off of all or part of its interest in NYSE Group or NYSE Euronext, as applicable, or any subsidiary of NYSE Euronext operating an exchange that is affected by a material adverse change of law, as the case may be.

Governance of NYSE Euronext

Immediately following the exercise of a call option over a substantial portion of Euronext's business, and for so long as the Dutch foundation shall continue to hold any priority shares or ordinary shares, the application of the provisions of the combination agreement and of the bylaws of NYSE Euronext relating to the representation of European domiciliaries in the governing bodies of NYSE Euronext shall be suspended.

110

In addition, if:

•: after a period of six months following the exercise of a call option, the Dutch foundation shall continue to hold any ordinary shares of Euronext or of one or more subsidiaries that, taken together, represent a substantial portion of Euronext's business;
•: after a period of six months following the exercise of a call option, the foundation shall continue to hold any priority shares of Euronext or of one or more subsidiaries that, taken together, represent a substantial portion of Euronext's business at any time the board of directors of NYSE Euronext so determines; or
•: at any time, NYSE Euronext divests a direct or indirect controlling interest in Euronext;

then, the provisions of the combination agreement, the bylaws of NYSE Euronext and the certificate of incorporation of NYSE Euronext relating to the representation of European domiciliaries on the governing bodies of NYSE Euronext, to the supermajority requirements to enter into extraordinary transactions or into amendments of certain governance provisions of the certificate of incorporation or of the bylaws of NYSE Euronext and to the jurisdiction of European regulators shall become of no further force and effect, and any European directors and officers of NYSE Euronext appointed pursuant to the above provisions shall resign or be removed from their offices.

Term of the Undertaking

The above special arrangements have been submitted to the College of Regulators and to the SEC as an undertaking made in connection with the regulatory approvals of the combination.

The initial term of this undertaking will be ten years from the date of the completion of the combination, renewable for an indefinite number of successive one-year terms at the request of board of the foundation or the College of Regulators, in the case of the Dutch foundation, or the board of trustees of the trust or the SEC, in the case of the Delaware trust. However, following the initial ten renewals, each subsequent renewal shall require the consent of NYSE Euronext. In the event that NYSE Euronext does not consent to any such further renewal following a request from the College of Regulators or the SEC, as applicable, NYSE Euronext and Euronext or NYSE Euronext and NYSE Group, as applicable, will review and discuss the possibility of renewing the undertakings or the adoption of alternatives with the College of Regulators or the SEC, as applicable, based on the then existing facts and circumstances.

Material Dutch Tax Consequences

The following is a description of the material Dutch tax consequences of the exchange offer and the post-closing reorganization generally applicable to holders of Euronext shares. It does not discuss every aspect of Dutch taxation that may be relevant to a particular holder of Euronext shares in light of such holder's particular circumstances or to a holder who is subject to special treatment under applicable Dutch law. For example, this description does not address the Dutch tax considerations applicable to Dutch corporate entities that, although in principle subject to Dutch corporation tax, are, in whole or in part, specifically exempt from that tax, Dutch corporate entities that are exempt from Dutch corporation tax under the participation exemption as laid down in the Dutch Corporation Tax Act 1969 with respect to benefits derived from their Euronext shares, and Dutch corporate entities that are investment institutions (beleggingsinstelling) as defined in the Dutch Corporation Tax Act 1969 (Wet op de vennootschapsbelasting 1969). In addition, this description does not address the Dutch tax considerations to individual holders of Euronext shares whose Euronext shares and income or capital gains derived therefrom have a connection with such holder's past, present or future employment.

Euronext shareholders who do not tender their Euronext shares in the exchange offer are urged to read the description under "The Post-Closing Reorganization Effectuated Other Than Pursuant To The Compulsory Acquisition Procedure—Dividend Withholding Tax" of the Dutch dividend withholding tax imposed on a liquidating distribution made by Euronext (or its legal successor), which could substantially reduce the value of the consideration received by Euronext shareholders who do not tender their Euronext shares in the exchange offer.

This description is for general information only and does not purport to be a complete analysis of all potential tax effects that may apply to a holder. Each holder is strongly urged to consult its tax advisor to determine the tax consequences to such holder of the transactions contemplated by the combination agreement.

To the extent English terms and expressions are used to refer to Dutch tax concepts, the meaning to be attributed to such terms and expressions shall be the meaning to be attributed to the relevant concepts under Dutch tax law. Unless otherwise indicated, this description is based on the tax laws of the Netherlands as they are in force and in effect on the date hereof and therefore is subject to any changes to these laws after such date, which changes may have a retroactive effect and could affect the tax treatment described in this section.

General

As used in this description, you are a "Dutch individual" if:

•: you are an individual;
•: you are resident, or deemed to be resident, in the Netherlands for Dutch income tax purposes, or you have elected to be treated as a resident of the Netherlands for Dutch income tax purposes;
•: benefits derived or deemed to be derived from Euronext shares are not attributable to an enterprise from which you derive profits, whether as an entrepreneur (ondernemer) or pursuant to a co-entitlement to the net value of an enterprise, other than as an entrepreneur or a shareholder;

112

•: benefits derived or deemed to be derived from Euronext shares do not constitute benefits from miscellaneous activities (resultaat uit overige werkzaamheden); and
•: your Euronext shares do not form part of a substantial interest (aanmerkelijk belang) or a deemed substantial interest in Euronext within the meaning of Chapter 4 of the Dutch Income Tax Act 2001 (Wet inkomstenbelasting 2001).

An individual may, inter alia, derive benefits from Euronext shares that are taxable as benefits from miscellaneous activities in the following circumstances:

•: his investment activities go beyond the activities of an active portfolio investor, for instance in the case of the use of insider knowledge (voorkennis) or comparable forms of special knowledge; or
•: he makes or is deemed to make Euronext shares available, legally or in fact, directly or indirectly, to a related party as described in sections 3.91 and 3.92 of the Dutch Income Tax Act 2001 under circumstances described therein.

Generally, if a person holds an interest in Euronext, such interest forms part of a substantial interest or a deemed substantial interest in Euronext if any one or more of the following circumstances is present:

•: such person alone or, if he is an individual, together with his partner (partner), if any, directly or indirectly, owns shares in Euronext representing 5% or more of the total issued and outstanding capital (or the issued and outstanding capital of any class of its shares), or rights to acquire, directly or indirectly, shares, whether or not already issued, that represent 5% or more of Euronext's total issued and outstanding capital (or the issued and outstanding capital of any class of its shares), or the ownership of profit participating certificates (winstbewijzen) that relate to 5% or more of Euronext's annual profit or to 5% or more of its liquidation proceeds;
•: such person's shares, profit participating certificates or rights to acquire shares or profit participating certificates in Euronext have been acquired by him or are deemed to have been acquired by him under a Dutch non-recognition provision; or
•: such person's partner or any of his relatives by blood or by marriage in the direct line (including foster children) or of those of his partner has a substantial interest (as described in the preceding two bullet points) in Euronext.

A person who is entitled to the benefits from shares or profit participating certificates (for instance, a holder of a right of usufruct) is deemed to be a holder of shares or profit participating certificates, as the case may be, and his entitlement to benefits is considered a share or profit participating certificate, as the case may be.

As used in this description, you are a "Dutch corporate entity" if:

•: you are a corporate entity (including an association that is taxable as a corporate entity) that is subject to Dutch corporation tax in respect of benefits derived from its Euronext shares, including any capital gains realized on the disposal thereof; and
•: you are resident, or deemed to be resident, in the Netherlands for Dutch corporation tax purposes.

As used in this description, you are a "non-resident holder" of Euronext shares if:

•: you are neither resident, nor deemed to be resident, in the Netherlands for purposes of Dutch income tax or corporation tax, as the case may be, and, if you are an individual, you have not elected to be treated as a resident of the Netherlands for Dutch income tax purposes;
•: you do not derive profits from an enterprise, whether as an entrepreneur (ondernemer) or pursuant to a co-entitlement to the net value of such enterprise, other than as an entrepreneur or a shareholder, in the case of an individual, or other than as a holder of securities, in other cases,

113

which enterprise is either managed in the Netherlands or carried on, in whole or in part, through a permanent establishment or a permanent representative in the Netherlands, as the case may be;

•: if you are an individual, you do not derive benefits from Euronext shares that are taxable as benefits from miscellaneous activities in the Netherlands.
•: if you are not an individual, you are not a qualifying parent company within the meaning of the EU Parent Subsidiary Directive (Directive 90/435/EEC, as amended); and
•: your Euronext shares do not form part of a substantial interest or a deemed substantial interest in Euronext within the meaning of Chapter 4 of the Dutch Income Tax Act 2001, unless such interest forms part of the assets of an enterprise (for the circumstances under which an interest in Euronext forms part of a substantial interest or a deemed substantial interest in Euronext, see the above).

The Exchange Offer And The Post-Closing Reorganization Effectuated Pursuant To The Compulsory Acquisition Procedure (Uitkoopregeling) In Accordance With Article 2:92a Of The Dutch Civil Code

The following description is only applicable (i) to holders of Euronext shares who tender their Euronext shares in the exchange offer and (ii) to holders of Euronext shares who do not tender their Euronext shares in the exchange offer if such holder's Euronext shares are acquired pursuant to the compulsory acquisition procedure (uitkoopregeling) in accordance with article 2:92a of the Dutch Civil Code. The compulsory acquisition procedure will only be available if 95% or more of the outstanding Euronext shares are acquired in the exchange offer. Accordingly, there can be no assurance to holders of Euronext shares who do not tender their Euronext shares in the exchange offer that such shares will be acquired through the compulsory acquisition procedure.

Dividend Withholding Tax

The exchange of a Euronext share for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock (or any other combination of cash and NYSE Euronext common stock that may be paid to Euronext shareholders who make the cash election or the stock election) in the exchange offer, and the exchange of a Euronext share for cash pursuant to the compulsory acquisition procedure (uitkoopregeling), as the case may be, will not be subject to Dutch dividend withholding tax.

Taxes on Income and Capital Gains

Dutch Resident Holders of Euronext Shares

Dutch Individuals. If you are a Dutch individual, benefits from your Euronext shares are taxed as a benefit from savings and investments (voordeel uit sparen en beleggen) and such benefit is deemed to be 4% per annum of the average of your "yield basis" (rendementsgrondslag) at the beginning and at the end of the year, insofar as that average exceeds the "exempt net asset amount" (heffingvrij vermogen). The benefit is taxed at the rate of 30%. The value of your Euronext shares forms part of your yield basis. Actual benefits derived from your Euronext shares, including any capital gains realized on the disposal thereof, and thus the capital gains realized upon the exchange of the Euronext shares in the exchange offer for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock per Euronext share (or any other combination of cash and NYSE Euronext common stock that may be paid to holders who make the cash election or the stock election), and the capital gain realized on the disposal thereof pursuant to the compulsory acquisition procedure (uitkoopregeling), as the case may be, are not as such subject to Dutch income tax.

Dutch Corporate Entities. If you are a Dutch corporate entity, any benefits derived or deemed to be derived by you from Euronext shares, including any capital gains realized on the disposal thereof in the exchange offer or pursuant to the compulsory acquisition procedure (uitkoopregeling), are generally subject to Dutch corporation tax. Generally, any capital gains realized upon the exchange of the Euronext shares in the exchange offer for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock per

114

Euronext share (or any other combination of cash and NYSE Euronext common stock that may be paid to holders who make the cash election or the stock election), or capital gains realized upon the exchange of Euronext share pursuant to the compulsory acquisition procedure (uitkoopregeling), as the case may be, by such holder must be taken into account in determining such benefits. In general, the capital gain, if any, realized will be equal to the excess of (i) the fair market value of the NYSE Euronext common stock, if any, and cash, if any, received by such shareholder in exchange for its Euronext shares, over (ii) such shareholder's fiscal book value of the Euronext shares exchanged.

Non-Resident Holders of Euronext Shares

If you are a non-resident holder of Euronext shares you will not be subject to any Dutch taxes on income or capital gains in respect of any benefits derived from your Euronext shares, including any capital gains realized on the disposal thereof. Accordingly, a non-resident holder generally will not be subject to any Dutch taxes on capital gains realized upon the exchange of the Euronext shares for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock per Euronext share (or any other combination of cash and NYSE Euronext common stock that may be paid to holders who make the cash election or the stock election), or upon the exchange of Euronext shares for cash pursuant to the compulsory acquisition procedure (uitkoopregeling), as the case may be.

Other Taxes and Duties

No Dutch registration tax, transfer tax, stamp duty or any other similar documentary tax or duty will be payable in the Netherlands in respect of the exchange of a Euronext share in the exchange offer or pursuant to the compulsory acquisition procedure (uitkoopregeling).

The Post-Closing Reorganization Effectuated Other Than Pursuant To The Compulsory Acquisition Procedure

Dividend Withholding Tax

If the exchange offer is successful, but less than 95% of the Euronext shares are acquired pursuant to the exchange offer, NYSE Euronext intends to effectuate a post-closing corporate reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly-owned subsidiary of NYSE Euronext. Details of the steps that may be implemented are described under "The Combination Agreement—Post-Closing Reorganization—Structural Steps to Effect Post-Closing Reorganization." The structure of the post-closing reorganization will depend, among other things, on the percentage of the Euronext shares tendered in the exchange offer, and we may not be able to determine the structure of the post-closing reorganization until the expiration of the exchange offer. The steps under consideration include, inter alia, delivery of the offer consideration through a liquidation of Euronext (or its legal successor). In the event of such a liquidation of Euronext (or its legal successor), the liquidating distribution payable to Euronext shareholders who did not tender their Euronext shares in the exchange offer will be subject to Dutch dividend withholding tax to the extent the fair market value of the NYSE Euronext shares and cash distributed per Euronext share (or share of its legal successsor) exceeds the average paid-up capital per Euronext share (or share of its legal successor), as recognized for Dutch dividend withholding tax purposes. As of the date of this document, the average paid-up capital per Euronext share as recognized for Dutch dividend withholding tax purposes is estimated to be €17.60. Based on the value of the offer consideration as of the date hereof, €56.90 of the liquidating distribution paid in respect of each Euronext share would be subject to Dutch dividend withholding tax at a rate of 25%. Under recently proposed draft legislation, the Dutch dividend withholding tax rate would be reduced to 15% as of January 1, 2007. There can be no assurance that such legislation will be enacted. The Dutch dividend withholding tax required to be withheld by Euronext (or its legal successor) upon a liquidating distribution could substantially decrease the net proceeds of any liquidating distribution to Euronext shareholders. Euronext shareholders who do not tender their Euronext shares in the exchange offer accept

115

the risk that application of the Dutch dividend withholding tax rules could cause the value of the consideration received in exchange for their Euronext shares in the post-closing reorganization to be substantially less than the value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer.

Dutch Resident Holders of Euronext Shares

A Dutch individual, other than an individual that has elected to be treated as a resident of the Netherlands for Dutch income tax purposes, or a Dutch corporate entity generally can credit Dutch dividend withholding tax against its Dutch income tax or Dutch corporation tax liability, as the case may be, and generally is entitled to a refund in the form of a negative assessment of Dutch dividend withholding tax insofar as such tax, together with any other creditable domestic and/or foreign taxes, exceeds its aggregate Dutch income tax or Dutch corporation tax liability, provided that, in the case of a Dutch corporate entity, (i) the liquidating distribution in respect of which such dividend withholding tax is withheld is included in its taxable profits and (ii) it has timely and duly filed a corporation tax return. In the case of a Dutch corporate entity for which the liquidating distribution is not included in its taxable profits, the dividend withholding tax withheld thereon is refunded upon a timely and duly filed request. An individual that has elected to be treated as a resident of the Netherlands for Dutch income tax purposes will only be entitled to credit such withholding tax or to a refund of dividend withholding tax in excess of his income tax liability if the liquidating distribution forms part of his Dutch source income. Pursuant to domestic rules to avoid dividend stripping, Dutch dividend withholding tax will only be creditable by or refundable to the beneficial owner (uiteindelijk gerechtigde) of the liquidating distribution. A holder of Euronext shares (or of shares of its legal successor) who receives the liquidating distribution will not be recognized as the beneficial owner of such liquidating distribution if, in connection with the receipt of the liquidating distribution, it has given a consideration, in the framework of a series of transactions, including, without limitation, the mere acquisition of one or more dividend coupons or the creation of short-term rights of enjoyment of shares (kortlopende genotsrechten op aandelen), whereas it may be presumed that (i) such liquidating distribution in whole or in part, directly or indirectly, inures to a person who would not have been entitled to an exemption from, or who would have been entitled to a smaller reduction or refund of, or credit for, dividend withholding tax than the actual recipient of the liquidating distribution; and (ii) such person acquires or retains, directly or indirectly, an interest in Euronext shares or similar instruments, comparable to its interest in Euronext shares (or its legal successor) prior to the time the composite transaction was first initiated.

Non-Resident Holders of Euronext Shares

If a non-resident holder of Euronext shares is resident in a country that has concluded an income tax treaty with the Netherlands (or is resident in the Netherlands Antilles or Aruba), such holder may be eligible for a partial relief from the Dutch dividend withholding tax, provided such relief is timely and duly claimed. Pursuant to domestic rules to avoid dividend stripping, dividend withholding tax relief will only be available to the beneficial owner of the liquidating distribution. The Dutch tax authorities have taken the position that this beneficial-ownership test can also be applied to deny relief from dividend withholding tax under income tax treaties and the tax Arrangement for the Kingdom (Belastingregeling voor het Koninkrijk). Non-resident holders of Euronext shares should consult their tax advisors regarding the possibility of claiming a reduced rate of withholding under an applicable income tax treaty.

Taxes on Income and Capital Gains

Dutch Resident Holders of Euronext Shares

Dutch Individual. If you are a Dutch individual, benefits from your Euronext shares are taxed as a benefit from savings and investments (voordeel uit sparen en beleggen) and such benefit is deemed to be 4% per annum of the average of your "yield basis" (rendementsgrondslag) at the beginning and at the end of

116

the year, insofar as that average exceeds the "exempt net asset amount" (heffingvrij vermogen). The benefit is taxed at the rate of 30%. The value of your Euronext shares forms part of your yield basis. Actual benefits derived from your Euronext shares, including any of the liquidating distribution made by Euronext (or its legal successor) will not as such be subject to Dutch income tax.

Dutch Corporate Entities. If you are a Dutch corporate entity, any benefits derived or deemed to be derived by you from Euronext shares, including benefits derived upon the liquidation of Euronext (or its legal successor), are generally subject to Dutch corporation tax. Generally, the gross liquidating distribution made by Euronext (or its legal successor) in excess of the fiscal book value of the Euronext shares, must be taken into account in determining such benefits.

Non-Resident Holders of Euronext Shares

If you are a non-resident holder of Euronext shares you will not be subject to any Dutch taxes on income or capital gains in respect of any benefits derived from Euronext shares, including benefit derived upon the liquidation of Euronext (or its legal successor).

Other Taxes and Duties

No Dutch registration tax, transfer tax, stamp duty or any other similar documentary tax or duty will be payable in the Netherlands in respect of the liquidating distribution made by Euronext (or its legal successor).

Material U.S. Federal Income Tax Consequences

The following is a discussion of (i) the material U.S. federal income tax consequences of the merger to U.S. holders of NYSE Group common stock and (ii) the material U.S. federal income tax consequences of the exchange offer and the post-closing reorganization to holders of Euronext shares. This discussion is based on the Internal Revenue Code of 1986, as amended, existing and proposed U.S. Treasury regulations thereunder, and administrative rulings and court decisions in effect as of the date hereof, all of which are subject to change at any time, possibly with retroactive effect.

For purposes of this discussion, the term "U.S. holder" means a beneficial owner of NYSE Group common stock or Euronext shares, as applicable, that is for U.S. federal income tax purposes:

•: a citizen or individual resident of the United States;
•: a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized under the laws of the United States or any of its political subdivisions;
•: a trust if it (i) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or (ii) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person; or
•: an estate the income of which is subject to U.S. federal income tax regardless of its source.

For purposes of this discussion, the term "non-U.S. holder" means a beneficial owner of NYSE Group common stock or Euronext shares, as applicable, that is not a U.S. holder (other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes).

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds NYSE Group common stock or Euronext shares, as applicable, the tax treatment of a person treated as a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. If for U.S. federal income tax purposes you are treated as a partner in a partnership holding NYSE Group common stock or Euronext shares, as applicable, you should consult your tax advisor regarding the tax consequences of the merger, the exchange offer and the post-closing reorganization.

117

This discussion only addresses holders of NYSE Group common stock and Euronext shares that hold their NYSE Group common stock or Euronext shares, as applicable, as a capital asset within the meaning of Section 1221 of the Internal Revenue Code. Further, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to a holder of NYSE Group common stock or Euronext shares, as applicable, in light of such holder's particular circumstances or that may be applicable to holders subject to special treatment under U.S. federal income tax law (including, for example, financial institutions, dealers in securities, traders in securities that elect mark-to-market treatment, insurance companies, tax-exempt entities, holders who acquired NYSE Group common stock or Euronext shares, as applicable, pursuant to the exercise of employee stock options or otherwise as compensation, entities or arrangements treated as partnerships for U.S. federal income tax purposes, holders liable for the alternative minimum tax, holders who hold their NYSE Group common stock or Euronext shares, as applicable, as part of a hedge, straddle, constructive sale or conversion transaction, U.S. holders whose functional currency is not the U.S. dollar, U.S. expatriates, "controlled foreign corporations," "passive foreign investment companies," which we refer to as "PFICs" and, except to the extent specifically discussed below, non-U.S. holders). This discussion does not address the tax consequences to any person who actually or constructively owns 5% or more of NYSE Group common stock or Euronext shares or any person who actually or constructively own both NYSE Group common stock and Euronext shares. In addition, no information is provided herein with respect to the tax consequences of the merger, the exchange offer or the post-closing reorganization under applicable state, local or non-U.S. laws or U.S. federal laws other than those pertaining to the U.S. federal income tax.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE MERGER, THE EXCHANGE OFFER AND THE POST-CLOSING REORGANIZATION. HOLDERS OF NYSE GROUP COMMON STOCK AND HOLDERS OF EURONEXT SHARES, AS APPLICABLE, ARE URGED TO CONSULT WITH THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL OR NON-U.S. INCOME AND OTHER TAX LAWS) OF THE MERGER, THE EXCHANGE OFFER AND THE POST-CLOSING REORGANIZATION.

It is a condition to the obligation of NYSE Euronext to file and commence the exchange offer that NYSE Group receive an opinion from its counsel, Wachtell Lipton, dated as of the filing of the exchange offer, to the effect that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code. This opinion will be based on assumptions and representations set forth or referred to in the opinion. NYSE Group does not intend to waive this condition to closing, and will not waive this condition without recirculating this document in order to resolicit NYSE Group stockholder approval.

The tax opinion is not binding on the Internal Revenue Service, or the courts, and NYSE Group does not intend to request a ruling from the Internal Revenue Service with respect to the U.S. federal income tax consequences of the merger. Accordingly, there can be no assurance that the Internal Revenue Service will not disagree with or challenge any of the conclusions described below. The following discussion assumes that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code.

Tax Consequences of the Merger to U.S. Holders of NYSE Group Common Stock

A U.S. holder of NYSE Group common stock will not recognize gain or loss upon receipt of NYSE Euronext common stock in exchange for its NYSE Group common stock in the merger. The aggregate tax basis of the shares of NYSE Euronext common stock received will be equal to the aggregate tax basis in the NYSE Group common stock surrendered. The holding period of the NYSE Euronext common stock received will include the holding period of the NYSE Group common stock surrendered.

118

Tax Consequences of the Exchange Offer and the Post-Closing Reorganization to U.S. and Non-U.S. Holders of Euronext shares

U.S. Holders

The combination agreement contemplates that the receipt by holders of Euronext shares of the offer consideration in the exchange offer and in the post-closing reorganization will be structured as a taxable transaction for U.S. federal income tax purposes, unless NYSE Group elects, subject to the provisions of the combination agreement, to structure the post-closing reorganization so that, in the opinion of counsel to NYSE Group, the exchange offer together with the post-closing reorganization, is treated either as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code or an exchange described in Section 351 of the Internal Revenue Code.

As of the date of this document, NYSE Group has not made the election described in the preceding paragraph. In addition, because the structure of the post-closing reorganization may depend, among other things, on the percentage of the Euronext shares tendered in the exchange offer, we may not be able to determine the structure of the post-closing reorganization and whether to make the election described above until after the expiration of the exchange offer. Holders of Euronext shares should recognize and consider that the combination agreement contemplates that the receipt by holders of Euronext shares of the consideration in the exchange offer and in the post-closing reorganization will be structured as a taxable transaction for U.S. federal income tax purposes.

Taxable Exchange. If, as currently contemplated by the combination agreement, the receipt by U.S. holders of Euronext shares of the offer consideration in the exchange offer or in the post-closing reorganization is treated as a taxable transaction, a U.S. holder of Euronext shares will recognize capital gain or loss in an amount equal to the difference, if any, between the amount realized and the U.S. holder's tax basis, determined in U.S. dollars, in the Euronext shares surrendered. The amount realized will be the fair market value of the NYSE Euronext common stock, if any, plus the amount of cash, if any, received pursuant to the exchange offer or the post-closing reorganization. Generally, such capital gain or loss will be long-term capital gain or loss if the holding period for the Euronext shares surrendered in the exchange offer or the post-closing reorganization is greater than one year as of the closing of the exchange offer or the post-closing reorganization, as applicable. The deductibility of capital losses is subject to limitations. If a U.S. holder acquired different blocks of Euronext shares at different times or different prices, any gain or loss must be determined separately for each block of Euronext shares.

Any cash consideration paid in Euros will be included in the income of a U.S. holder of Euronext shares in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of receipt by such holder, regardless of whether the cash consideration is in fact converted into U.S. dollars. U.S. holders should consult their own tax advisors regarding the treatment of foreign currency gain or loss, if any, on any Euros received by a U.S. holder that are converted into U.S. dollars on a date subsequent to receipt.

For foreign tax credit purposes, any capital gain or loss recognized by a U.S. holder upon the exchange of Euronext shares pursuant to the exchange offer or the post-closing reorganization, as applicable, generally will be U.S. source "passive income."

Reorganization within the meaning of Section 368(a) of the Internal Revenue Code or Exchange described in Section 351 of the Code. If NYSE Group elects to structure the exchange offer together with the post-closing reorganization as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code or as an Exchange described in Section 351 of the Code, and the exchange offer together with the post-closing reorganization so qualifies, the material U.S. federal income tax consequences to holders of Euronext shares, in general, are as follows:

•: U.S. Holders Who Receive Solely NYSE Euronext Common Stock. A U.S. holder of Euronext shares will not recognize gain or loss upon receipt of NYSE Euronext common stock solely in exchange for

119

Euronext shares, except with respect to cash received in lieu of fractional shares of NYSE Euronext common stock (as discussed below). The aggregate tax basis of the shares of NYSE Euronext common stock received (including any fractional shares deemed received and exchanged for cash) will be equal to the aggregate tax basis in the Euronext shares exchanged. The holding period of the NYSE Euronext common stock received (including any fractional shares deemed received and exchanged for cash) will include the holding period of the Euronext shares exchanged.

•: U.S. Holders Who Receive Solely Cash. A U.S. holder of Euronext shares who exchanges such shares solely for cash generally will recognize capital gain or loss in an amount equal to the difference, if any, between the amount of cash received and the U.S. holder's tax basis, determined in U.S. dollars in the Euronext shares exchanged. Generally, such capital gain or loss will be long-term capital gain or loss if the holding period for the Euronext shares surrendered in the exchange offer or the post-closing reorganization is greater than one year as of the closing date of the exchange offer or the post-closing reorganization, as applicable. The deductibility of capital losses is subject to limitations. If a U.S. holder acquired different blocks of Euronext shares at different times or different prices, any gain or loss must be determined separately for each block of Euronext shares.
•: U.S. Holders Who Receive a Combination of NYSE Euronext Common Stock and Cash. If the U.S. holder's adjusted tax basis, determined in U.S. dollars, in the Euronext shares surrendered is less than the sum of the fair market value, as of the closing date of the exchange offer or the post-closing reorganization, as applicable, of the NYSE Euronext common stock and the amount of cash received by the U.S. holder, then the U.S. holder will recognize gain in an amount equal to the lesser of (i) the sum of the amount of cash and the fair market value of the NYSE Euronext common stock received, minus the adjusted tax basis, determined in U.S. dollars, of the Euronext shares exchanged therefor, and (ii) the amount of cash received by the holder in the exchange offer or the post-closing reorganization, as applicable. However, if a U.S. holder's adjusted tax basis, determined in U.S. dollars, in the Euronext shares exchanged is greater than the sum of the amount of cash and the fair market value of the NYSE Euronext common stock received, the U.S. holder's loss will not be currently allowed or recognized for U.S. federal income tax purposes. If a U.S. holder acquired different blocks of Euronext shares at different times or different prices, the holder should consult the holder's tax advisor regarding the manner in which gain or loss should be determined. Any recognized gain generally will be long-term capital gain if, as of closing date of the exchange offer or the post-closing reorganization, the U.S. holder's holding period with respect to the Euronext shares exchanged is greater than one year. The aggregate tax basis of the NYSE Euronext common stock received (including any fractional shares deemed received and exchanged for cash) by a U.S. holder that exchanges its Euronext shares for a combination of NYSE Euronext common stock and cash will be equal to the aggregate adjusted tax basis, determined in U.S. dollars, of the Euronext shares exchanged, reduced by the amount of cash received by the holder (excluding any cash received in lieu of fractional shares of NYSE Euronext common stock) and increased by the amount of gain, if any, recognized by the holder (excluding any gain recognized with respect to cash received in lieu of fractional shares of NYSE Euronext common stock) in the exchange offer or the post-closing reorganization, as applicable. The holding period of the NYSE Euronext common stock received (including any fractional shares deemed received and exchanged for cash) will include the holding period of the Euronext shares surrendered. Notwithstanding the foregoing, if a U.S. holder actually or constructively owns NYSE Euronext common stock other than NYSE Euronext common stock received in the exchange offer or the post-closing reorganization, the recognized gain in some cases would be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Internal Revenue Code, in which case such gain would be treated as dividend income. In such cases, U.S. holders that are corporations should consult their tax advisors regarding the potential applicability of the "extraordinary dividend" provisions of the Internal Revenue Code.

120

Cash in Lieu of Fractional Shares. If the exchange offer, together with the post-closing reorganization, qualifies as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code, a U.S. holder of Euronext shares who receives cash in lieu of a fractional share of NYSE Euronext common stock in the exchange offer or the post-closing reorganization generally will be treated as having received such fractional share in the exchange offer or the post-closing reorganization, as applicable, and then as having received cash in exchange for such fractional share. Gain or loss generally will be recognized by such U.S. holder based on the difference between the amount of cash received in lieu of the fractional share and the tax basis allocated to such fractional share of NYSE Euronext common stock.

If the exchange offer, together with the post-closing reorganization, qualifies as an exchange described in Section 351 of the Internal Revenue Code, a U.S. holder of Euronext shares who receives cash in lieu of a fractional share of NYSE Euronext common stock in the exchange offer or the post-closing reorganization, as applicable, generally will be treated as having received cash in exchange for Euronext common stock as described above under "U.S. Holders Who Receive a Combination of NYSE Euronext Common Stock and Cash."

Passive Foreign Investment Company Status

A non-U.S. corporation will be classified as a Passive Foreign Investment Company (or PFIC) for any taxable year if (1) at least 75 percent of its gross income consists of passive income (such as dividends, interest, rents, royalties or gains on the disposition of certain minority interests), or (2) at least 50 percent of the average value of its assets consists of assets that produce, or are held for the production of, passive income. If Euronext were characterized as a PFIC, such characterization would result in adverse tax consequences to U.S. holders, and U.S. federal income tax consequences different from those described above may apply. These consequences may include having gains realized on the disposition of Euronext shares treated as ordinary income rather than capital gain and being subject to punitive interest charges on such gains. U.S. holders should consult their own tax advisors regarding the potential application of the PFIC rules to their disposition of Euronext shares in connection with the exchange offer or the post-closing reorganization.

Certain Foreign Tax Credit Considerations for U.S. Holders that do Not Tender their Euronext Shares

A U.S. holder that does not tender its Euronext shares in the exchange offer may be subject to Dutch dividend withholding tax on the consideration paid to such holder in the post-closing reorganization. See, "The Combination—Material Dutch Tax Consequences—Post Closing Reorganization Effectuated Other than Pursuant to the Compulsory Acquisition Procedure—Dividend Withholding Tax." Subject to certain conditions and limitations, the Dutch dividend withholding tax on the consideration paid to a U.S. holder in the post-closing reorganization will be treated as a tax eligible for credit against such holder's U.S. federal income tax liability. Among other limitations, however, foreign tax credits generally can be applied only to offset U.S. federal income tax imposed on income from foreign sources. Because any gain recognized by a U.S. holder of Euronext shares in the post-closing reorganization generally would be treated as U.S. source income for foreign tax credit purposes, a U.S. holder's ability to credit any Dutch dividend withholding tax on the consideration paid to such holder in the post-closing reorganization would

121

be conditioned upon the U.S. holder having sufficient other income from foreign sources. Alternatively, a U.S. holder may deduct any Dutch dividend withholding tax in computing taxable income. Foreign tax credits generally will not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions in Euronext shares. The rules governing foreign tax credits are very complex. U.S. holders should consult their own tax advisors regarding the U.S. federal income tax consequences arising from the imposition of Dutch dividend withholding tax and regarding the application of the foreign tax credit rules in light of their particular circumstances.

Non-U.S. Holders

A non-U.S. holder's gain or loss from the exchange offer and the post-closing reorganization generally will be determined in the same manner as that of a U.S. holder. However, a non-U.S. holder generally will not be subject to federal income tax on any gain recognized from the exchange offer or the post-closing reorganization, unless (i) the gain is effectively connected with a U.S. trade or business of the non-U.S. holder (or, if certain income tax treaties apply, is attributable to a U.S. permanent establishment), or (ii) the holder is an individual who has been present in the United States for 183 days or more during the taxable year of the disposition and certain other conditions are satisfied.

A non-U.S. holder whose gain is effectively connected with the conduct of trade or business in the United States will be subject to U.S. federal income tax on such gain in the same manner as a U.S. holder. In addition, a non-U.S. holder that is a corporation may be subject to a branch profits tax equal to 30% (or lesser rate under an applicable income tax treaty) on such effectively connected gain.

Information Reporting and Backup Withholding. Payments of cash made to a U.S. holder or non-U.S. holder of Euronext shares in connection with the exchange offer or the post-closing reorganization, under certain circumstances, may be subject to information reporting and "backup withholding" at a rate of 28%, unless such holder provides proof of an applicable exemption or furnishes its taxpayer identification number, and otherwise complies with all applicable requirements of the backup withholding rules. In this regard, a non-U.S. holder under certain circumstances may be required to provide an IRS Form W8-BEN certifying, under penalties of perjury, as to its non-U.S. status. Any amounts withheld under the backup withholding rules are not additional tax and may be allowed as a refund or credit against the holder's U.S. federal income tax liability, provided the required information is furnished to the Internal Revenue Service.

Accounting Treatment

Under U.S. GAAP, the combination will be accounted for as an acquisition of Euronext by NYSE Group under the purchase method of accounting. Under the purchase method, the cost of the acquisition will be based on the amount of cash paid to holders of Euronext shares, the market value of NYSE Euronext common shares issued to holders of Euronext shares, and the direct transaction costs of the combination. Under U.S. GAAP, the market value of the NYSE Euronext common shares to be issued will be based on the average price of NYSE Group common stock for the period beginning two days before and ending two days after the announcement of the execution of the combination agreement, such date being June 1, 2006.

Credit Facility

In connection with the exchange offer, NYSE Euronext will enter into a credit facility agreement that will permit NYSE Euronext to borrow amounts sufficient to fund the cash portion of the exchange offer consideration, which is expected to be $3.0 billion. NYSE Euronext may only borrow amounts under this credit facility agreement if the combination is successful. If the combination is successful, NYSE Euronext expects to use the credit facility as an undrawn back stop for a Global Commercial Paper Program, which NYSE Euronext will use mainly to finance the cash portion of the consideration to be paid to Euronext shareholders pursuant to the exchange offer. The credit facility will include terms and conditions

122

customary for agreements of this type, which could restrict NYSE Euronext's ability to engage in additional transactions or incur additional indebtedness.

Regulatory Approvals

Under applicable French stock market regulations, the AMF is responsible for approving the terms and conditions of the exchange offer and the French note d'information. The approval (decision de conformité) issued by the AMF may be challenged in court by any interested party within 10 days following its publication in the BALO, the French legal gazette.

Competition and Antitrust

U.S. Antitrust Clearance. NYSE Group and Euronext are not required to make notifications under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the rules promulgated under the HSR Act by the Federal Trade Commission (the "FTC").

European Competition Authorities. Competition and regulatory notifications to and approvals from the following European authorities may be required:

•: United Kingdom: Confirmation has been sought from the Office of Fair Trading, pursuant to the Enterprise Act 2002, that the combination will not be referred to the Competition Commission. Were the Office of Fair Trading to refer the combination and/or the exchange offer to the Competition Commission, the combination and/or the exchange offer would be conditional on receipt of a decision by the Competition Commission that the combination may not be expected to result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.
•: Portugal: NYSE Group and NYSE shall submit a notification pursuant to the Portuguese Competition Law (Act No. 18/2003). Alternatively, the Portuguese Competition Authority ("Autoridade da Concorrência") might open an investigation absent such notification. In either case, the combination and/or exchange offer would be conditional on clearance of the transaction by the Autoridade da Concorrência, under Art. 12 of the Portuguese Competition Law (Act No 18/2003).

The Antitrust Division of the U.S. Department of Justice and the FTC frequently scrutinize the legality under the antitrust laws of business combination transactions. At any time before or after the combination, antitrust or competition authorities in the United States (including, for example, the U.S. Department of Justice, FTC or a state attorney general) or a non-U.S. competition authority could take action under the applicable competition or antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the combination or seeking divestiture of substantial assets of NYSE Group or Euronext or their subsidiaries. Private parties may also bring legal actions under the antitrust laws under certain circumstances. Although NYSE Group, Euronext and NYSE Euronext believe that they will receive the requisite regulatory approvals for the combination, they can give no assurance that a challenge to the combination will not be made or, if made, would be unsuccessful. Obtaining certain government approvals applicable to the exchange offer or merger is a condition to the combination. See "The Combination Agreement—Conditions to Completing the Combination."

Securities Regulatory Authorities

SEC Approvals. The NYSE is registered as a national securities exchange pursuant to Section 6 of the Exchange Act. As a registered national securities exchange, NYSE Group must comply with certain obligations under the Exchange Act. NYSE Arca, Inc. is also a registered national securities exchange. Under Section 19 of the Exchange Act and the related rules of the SEC, all changes in the rules of an SRO, such as the NYSE and NYSE Arca, Inc., must be submitted to the SEC for approval, and this can include certain proposed amendments to the certificate of incorporation or bylaws of NYSE Group. No proposed rule change can take effect unless approved by the SEC or otherwise permitted by Section 19.

123

Under Section 19 of the Exchange Act, the text of the proposed rule change, together with a concise general statement of the statutory basis, and the purpose of the change, must be submitted to the SEC, which then gives interested parties the opportunity to comment by publishing the proposal in the Federal Register. Comment letters typically are forwarded to the SRO for response. Within a period of 35 days of the publication of the proposed rule change (or a longer period of up to 90 days, if the SEC considers it appropriate), the SEC must either approve the proposal, or institute proceedings to determine whether the proposed rule change should be disapproved. Such proceedings should be concluded within 180 days of the date of the publication of the proposed rule change, although the SEC may extend the deadline by another 60 days if necessary. The SEC will approve a proposed rule change if it finds that the change is consistent with the requirements of the Exchange Act and the rules and regulations of the Exchange Act. SROs may consent to extensions of any of these periods and, as a practical matter, will generally do so while addressing any concerns raised by the SEC staff.

SEC approval of any applications under Rule 19b-4 under the Exchange Act submitted by the registered exchange subsidiaries of NYSE Group in connection with the proposed combination is a condition to the commencement of the exchange offer. See "The Combination Agreement—Conditions to Completing the Combination—Conditions to Filing and Commencing the Exchange Offer."

SEC Relief. UBS AG and Morgan Stanley, financial advisors to Euronext, applied to the SEC for exemptive relief from the provisions of Rule 14e-5 under the Exchange Act. The SEC granted the requested relief on July 13, 2006. Rule 14e-5, among other things, prohibits a person making a cash tender offer or exchange offer for an equity security, as well as any person acting, directly or indirectly, in concert with such person (or certain advisors or dealer-managers of such person), from purchasing, directly or indirectly, or making any arrangement to purchase such security or any related security except pursuant to such tender offer or exchange offer.

The relief granted to UBS AG and Morgan Stanley permits them, as well as their affiliates and separately identifiable departments, to engage in certain trading activities involving Euronext shares and various related derivative securities (which are referred to in this section collectively as the "specified Euronext securities") in the ordinary course of their businesses, none of which will be undertaken for the purpose of promoting or otherwise facilitating the exchange offer. Relief is subject, among other things, to the following conditions: (i) any trading activities will be conducted outside the United States; (ii) no purchases or arrangements to purchase specified Euronext securities, otherwise than pursuant to the exchange offer, will be made directly or indirectly on behalf of NYSE Euronext; (iii) all purchases of the specified Euronext securities by UBS AG and Morgan Stanley and their affiliates and departments during the exchange offer will be effected in the ordinary course of business and in compliance with the applicable rules of the AMF and any other applicable rules or regulations; (iv) the exchange offer documents will prominently disclose the possibility that UBS AG and Morgan Stanley and their affiliates and departments may purchase the specified Euronext securities outside the exchange offer; (v) UBS AG and Morgan Stanley will disclose in the United States information regarding such purchases to the extent such information is made public in France; and (vi) UBS AG and Morgan Stanley will provide to the SEC, upon request, a daily schedule of all transactions in the specified Euronext securities made by them or their affiliates and departments during the exchange offer, on a transaction-by-transaction basis, including the size, broker (if any), price and manner of such transaction. In addition, UBS AG and Morgan Stanley have agreed to comply during the exchange offer with the relevant provisions of the U.K. City Code on Takeovers and Mergers applicable to U.K. exempt principal traders as if they were subject to such provisions, except that trades will be reported to the AMF instead of to the U.K. Takeover Panel, as required by the General Rules of the AMF.

European Regulators. In addition, the following approvals by European regulators are conditions to the filing and commencement of the exchange offer. See "The Combination Agreement—Conditions to Completing the Combination":

124

•: the Dutch Minister of Finance shall have issued a declaration of no objection pursuant to section 26a of the Dutch Act on the Supervision of the Securities Trade 1995 allowing NYSE Euronext to acquire the Euronext shares;
•: the authorization from the French Comité des Etablissements de Crédit et des Entreprises d'Investissement ("CECEI") in accordance with the provisions of Article 2 of the French Règlement CRBF No. 96-16;
•: no objection of the French Autorité des Marchés Financiers (the "AMF") pursuant to the provisions of Articles 511-1 and 511-5 of the General Rules of the AMF;
•: the French Minister of Economy shall not have taken any of the steps set forth in Article 441-1 of the Code Monetaire et Financier to object to the completion of the exchange offer; and
•: the approval of the Committee of the Chairmen of the College of Regulators composed of the AMF, the Netherlands Authority for the Financial Markets (Autoriteit Financiele Markten) ("AFM"), the Belgian Banking, Finance, and Insurance Commission (Commission Bancaire, Financière et des Assurances) ("CBFA"), the Portuguese Securities Commission (Comissão do Mercado de Valores Mobiliarios) ("CMVM"), and the United Kingdom Financial Services Authority ("FSA"), pursuant to the Memoranda of Understanding dated March 22, 2001 and March 3, 2003 (together, the "College of Regulators").

Other Regulatory Approvals. Finally, there shall have been obtained and made, as a condition to the combination, all required approvals and filings to any governmental authority, the failure of which to be obtained or made, individually or in the aggregate, would reasonably be expected to result in a substantial detriment to one of the parties, and such approvals shall have been obtained on terms that would not be reasonably expected to have a substantial detriment. Under the combination agreement, a substantial detriment is defined as a material adverse effect on the business, continuing results of operations or financial condition of such person and its subsidiaries taken as a whole or a material adverse effect on the authority or ability of the NYSE or NYSE Arca, Inc. to continue as national securities exchanges and self-regulatory organizations or of Euronext Paris, Euronext Amsterdam, Euronext Lisbon, Euronext Brussels or LIFFE Administration and Management to continue to operate the markets they currently operate. See "The Combination Agreement—Conditions to Completing the Combination."

It is currently expected that a number of regulatory approvals will be solicited and a number of filings will be made in connection with the proposed combination, including:

•: prior non-opposition by the CBFA pursuant to Article 19 of the Law dated August 2, 2002;
•: authorization by the Belgian Minister of Economy pursuant to Article 12 of the Law dated August 2, 2002 as a result of the potential impact of the combination on the information technology systems;
•: prior approval by the Dutch Minister of Finance after consultation with the AFM pursuant to paragraph 4.3 of the formal exchange recognition dated September 22, 2000 and granted to Euronext and Euronext Amsterdam N.V. pursuant to Section 22 of the Dutch Act on the Supervision of the Securities Trade 1995;
•: notification to the FSA pursuant to REC 3.6.6(3)R of the Recognised Investment Exchanges and Recognised Clearing House Sourcebook of the FSA Handbook in respect of LIFFE Administration and Management;

125

•: approval by the CMVM pursuant to the Decree-law n.394/99 of October 13, 1999, as amended by Decree-law n.8-D/2002 of January 15 with respect to Interbolsa S.A.;
•: approvals by, or filings with, various regulators including the German BaFin, the Spanish Comision Nacional de Mercados de Valores, the AFM, the CECEI, [the Italian Commissione Nazionale per le Società et la Bolsa (which is referred to in this document as CONSOB)] and the CBFA with respect to the indirect subsidiaries of MBE Holding S.p.A.;
•: approvals by, or filings with, various regulators including the AMF, the Dutch Minister of Finance, the CONSOB, the Swiss Federal Banking Commission, the Japanese Minister of Finance and Financial Supervisory Agency, the Monetary Authority of Singapore, the SEC and the U.S. Commodity Futures Trading Commission ("CFTC") and the Taiwan Securities and Futures Commission with respect to the operations of Liffe Administration & Management and its subsidiaries;
•: applications to the NASDAQ with respect to Archipelago Trading Services, Inc. and Archipelago Securities, Inc. and its subsidiaries.

Commitment to Obtain Approvals

NYSE Group and Euronext have agreed to use reasonable best efforts to obtain as promptly as reasonably practicable all consents and approvals of any governmental entity or any other person required in connection with the combination, subject to limitations as set forth in the combination agreement (see "The Combination Agreement—Reasonable Best Efforts to Obtain Required Approvals").

General

While NYSE Group and Euronext believe that they will receive the requisite regulatory approvals for the combination, there can be no assurances regarding the timing of the approvals, their ability to obtain the approvals on satisfactory terms or the absence of litigation challenging these approvals. There can likewise be no assurance that U.S. federal, state or non-U.S. regulatory authorities will not attempt to challenge the combination on antitrust grounds or for other reasons, or, if a challenge is made, as to the results of the challenge. NYSE Group and Euronext's obligation to complete the combination is conditioned upon the receipt of approval of the combination from the SEC, U.S. federal and state governmental authorities, European regulators and other governmental authorities. See "The Combination Agreement—Conditions to Completing the Combination."

Restrictions on Sales of Shares by Affiliates of NYSE Group and Euronext

The shares of NYSE Euronext common stock to be issued in the exchange offer and the merger will be registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), and will be freely transferable under the Securities Act, except for shares of NYSE Euronext common stock issued to any person who is deemed to be an "affiliate" of NYSE Group or Euronext at the time of the NYSE Group special meeting or the Euronext extraordinary meeting, as applicable. It should be noted, however, that, although shares may be freely transferable under the Securities Act, certain of the shares of NYSE Euronext common stock issued in the merger may be subject to transfer restrictions under the NYSE Euronext certificate of incorporation. For a description of these restrictions, see "Description of NYSE Euronext Capital Stock—Transfer Restrictions." Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control with, either the NYSE Group or Euronext, and may include executive officers and directors of NYSE Group or Euronext, as well as significant stockholders of NYSE Group or Euronext. Affiliates may not sell their shares of NYSE Euronext common stock acquired in the exchange offer or the merger except pursuant to:

•: an effective registration statement under the Securities Act covering the resale of those shares;
•: an exemption under paragraph (d) of Rule 145 under the Securities Act; or

126

•: any other applicable exemption under the Securities Act.

Both NYSE Group and Euronext expect that each of their affiliates will agree with NYSE Euronext that the affiliate will not transfer any shares of stock received in the exchange offer or the merger, except in compliance with the Securities Act. Resales of NYSE Euronext common stock by affiliates of NYSE Group, Euronext or NYSE Euronext are not being registered pursuant to the registration statement of which this document forms a part.

Stock Exchange Listing and Stock Prices

NYSE Euronext common stock currently is not traded or quoted on a stock exchange or quotation system. However, NYSE Euronext intends to apply to list the shares of NYSE Euronext common stock on the NYSE (trading in U.S. dollars) under the symbol "[ • ]," and on Euronext Paris (Eurolist by Euronext) (trading in euros) under the symbol "[ • ]," (ISIN Code [ • ]) subject to official notice of issuance.

Shares of NYSE Group common stock are listed on the NYSE under the symbol "NYX." Shares of NYSE Group common stock will be delisted from the NYSE after the combination is completed, as permitted by applicable law. Euronext shares are listed on Euronext Paris (Eurolist by Euronext) under the symbol "NXT" (ISIN Code NL0000290641). NYSE Euronext intends to request the delisting of Euronext shares from Euronext Paris (Eurolist by Euronext) as soon as practicable and permitted after the combination or, if applicable, the post-closing reorganization is completed. Euronext shares may be delisted from Euronext Paris (Eurolist by Euronext) upon NYSE Euronext's request, only if Euronext Paris authorizes such delisting, it being specified that Euronext Paris may grant its authorization only if the liquidity of Euronext's shares is reduced to such an extent that delisting is in the market's best interest, and subject to the veto right of the AMF. For the reasons discussed below, if the exchange offer for Euronext shares is completed, depending on the number of Euronext shares tendered, there may no longer be an active trading market for the Euronext shares, and its liquidity could be materially adversely affected. If Euronext Paris were to delist Euronext shares, the market for Euronext shares could be adversely affected. Although it is possible that the Euronext shares would be traded on other securities exchanges or in the over-the-counter market, and the price quotations would be reported by such exchanges, other quotation systems or by other sources, there can be no assurance that any such trading quotations will occur. The extent of the public market for the Euronext shares and the availability of such quotations would depend upon the number of holders and/or the aggregate market value of the public float of Euronext shares remaining at such time and the interest in maintaining a market in such securities on the part of securities firms.

To the extent the availability of such listings or quotations depends on steps taken by NYSE Euronext, NYSE Euronext may or may not take such steps. Therefore, Euronext shareholders should not rely on any such listing or quotation being available following the successful completion of the exchange offer.

The following table sets forth, for the periods indicated, the high and low sale prices of NYSE Group common stock and Euronext shares.

NYSE Group common stock has been publicly traded only since March 8, 2006, the first day after the completion of the merger of the NYSE and Archipelago. Prior to that date, there was no public market in NYSE Group common stock.

THE COMBINATION AGREEMENT

This section of the document describes the material terms of the combination agreement. The following summary is qualified in its entirety by reference to the complete text of the combination agreement, which is incorporated by reference and attached as Annex A to this document. NYSE Group and Euronext urge you to read the full text of the combination agreement.

Structure of the Combination

Pursuant to the combination agreement, NYSE Group and Euronext have agreed to combine their businesses under a new holding company named NYSE Euronext. The effect of the combination will be that NYSE Group and Euronext will become subsidiaries of NYSE Euronext. Euronext's business will be brought under the new holding company through an exchange offer, and NYSE Group's business will be brought under the new holding company through a merger. Following the merger, NYSE Group will be a wholly owned subsidiary of NYSE Euronext. As soon as possible after the successful completion of the exchange offer and the merger, NYSE Euronext intends to effect the post-closing reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. The effect of the post-closing reorganization will be to eliminate any minority shareholder interest in Euronext remaining after the completion of the exchange offer. The following is a diagram of NYSE Euronext after completion of the combination and a successful post-closing reorganization:

The Exchange Offer

Consideration Offered to Euronext Shareholders

The combination agreement provides that Euronext will become a subsidiary of NYSE Euronext through an exchange offer. Following the filing of the exchange offer with the AMF, NYSE Euronext or a wholly owned subsidiary, subject to the approval of the AMF, will commence an exchange offer to acquire each outstanding Euronext share for €21.32 in cash (without interest) and 0.98 of a share of NYSE Euronext common stock. The foregoing mix of consideration is referred to as the "standard offer consideration." Assuming that each share of NYSE Euronext common stock has a value equal to one share of NYSE Group common stock, based on the closing price of $[ • ] per share of NYSE Group common stock and the euro-dollar noon buying rate of Federal Reserve Bank of New York on [ • ], 2006, the

129

terms of the exchange offer value each Euronext share at €[ • ]. The combination agreement contains no provision that permits either party to terminate the combination agreement, or that alters the exchange ratio, because the stock price of NYSE Group common stock or Euronext shares has fallen below any agreed-upon minimum price or has risen above an agreed-upon maximum price. See "Risk Factors."

If a Euronext shareholder holds exercisable options to acquire Euronext shares and would like to tender the underlying Euronext shares into the exchange offer, the Euronext shareholder must first exercise the options and then tender the underlying Euronext shares on or prior to the expiration date of the exchange offer. NYSE Euronext will not offer to acquire these options separately.

Mix and Match Election

The exchange offer will contain a "mix and match" election to permit Euronext shareholders to receive more cash or more stock for their tendered Euronext shares, to the extent that either is available. Specifically, instead of receiving the standard offer consideration for their Euronext shares, Euronext shareholders will have an opportunity to make either a cash election to receive all cash for their Euronext shares, or a stock election to receive all stock for their Euronext shares. However, the precise amount of cash payable in respect of any cash election, and the precise number of NYSE Euronext shares issuable in respect of any stock election will be determined prior to the filing of the exchange offer with the AMF and will depend on the volume-weighted average price of NYSE Group common stock during the 10 consecutive trading days ending immediately prior to the date of the filing of the exchange offer. In addition, both cash elections and stock elections are subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all tendering Euronext shareholders received the standard offer consideration. A cash election will be satisfied in full only to the extent that offsetting stock elections have been made by other tendering holders of Euronext shares in the exchange offer. Accordingly, there can be no assurance that Euronext shareholders will receive all of their consideration in the form that they have elected. The combination agreement contains no provision that permits either party to terminate the combination agreement, or that alters the exchange ratio, because the stock price of NYSE Group common stock or Euronext shares has fallen below any agreed-upon minimum price or has risen above an agreed-upon maximum price. See "Risk Factors."

Euronext shareholders who make no election will receive the standard offer consideration for their tendered Euronext shares.

In connection with the exchange offer, UBS AG and Morgan Stanley, financial advisors to Euronext, have received exemptive relief from the SEC permitting them to engage in certain trading activities involving the specified Euronext securities including making purchases of specified Euronext securities outside of the exchange offer, in the ordinary course of their business and subject to specified conditions. See "The Combination—Regulatory Approvals—Securities Regulatory Authorities—SEC Relief."

Commencement of the Exchange Offer

After the satisfaction or waiver of the conditions set forth below under "The Combination Agreement—Conditions to Completing the Combination—Conditions to Filing and Commencing the Exchange Offer," including approval of the combination agreement by the NYSE Group stockholders and Euronext shareholders, NYSE Euronext or a wholly owned subsidiary will file the exchange offer with the AMF in compliance with the General Rules of the AMF. Following approval by the AMF of the terms of the exchange offer and the French tender offer prospectus (note d'information and related documentation), NYSE Euronext or a wholly owned subsidiary will commence the exchange offer. In connection with the exchange offer, NYSE Euronext will also send a prospectus to U.S. holders of Euronext (which we refer to as the "exchange offer prospectus"). Accompanying the exchange offer prospectus will be transmittal materials and instructions for tendering shares in the exchange offer.

130

Expiration Date of the Exchange Offer; Extension of the Exchange Offer

The tender period for the exchange offer will be open for 25 trading days unless (i) the AMF extends the tender period of the exchange offer, (ii) the exchange offer lapses or is withdrawn prior to that time, or (iii) the exchange offer is suspended or extended by the AMF or by court if a claim has been filed. The timetable for the tender period for the exchange offer will be determined by the AMF and will be set forth in the exchange offer documentation. The AMF also has the sole authority to determine whether to extend the exchange offer period. The AMF may extend the exchange offer period under certain circumstances, including in the event of the initiation of a competing offer or of an improved offer. The exchange offer period may also be extended in case a claim challenging the validity of the AMF's decision to approve the exchange offer and the exchange offer documentation is validly filed with a court of competent jurisdiction. NYSE Euronext may not itself extend the exchange offer period. If the offer period is extended by the AMF, NYSE Euronext will issue a press release announcing the AMF's decision and the new expiration date and time of the extended exchange offer.

NYSE Euronext will not be obligated to purchase any tendered Euronext shares pursuant to the exchange offer unless Euronext shares representing at least two-thirds of the outstanding Euronext shares as of the closing of the exchange offer are validly tendered and not withdrawn in the exchange offer. After consultation with Euronext, NYSE Euronext may change the minimum tender condition so that it is not less than a majority of the Euronext shares and not less than a majority of the Euronext voting power, in each case outstanding on a fully diluted basis.

NYSE Euronext expects the AMF to publish the definitive results of the exchange offer not later than nine French trading days following the expiration date of the above offer period. However, upon determination that the minimum tender condition has been met, NYSE Euronext expects the AMF to publish provisional results prior to its publication of the definitive results. The AMF's publication of the definitive results of the exchange offer will disclose the total number of Euronext shares tendered into the exchange offer and the corresponding percentage of total capital and voting rights of Euronext that have been validly tendered.

If the minimum tender condition is satisfied, the exchange offer will be automatically re-opened by the AMF within ten French trading days following the publication of the definitive results. In this case, the exchange offer will be re-opened for a period of at least ten French trading days. Euronext shareholders will be entitled to make a mix and match election when tendering Euronext shares in the subsequent offering period. Such elections will also be subject to proration so that the total number of shares of NYSE Euronext issued and total amount of cash paid is equal to the amounts that would have been payable if all Euronext shareholders tendering in the subsequent offering period had made the standard offer election. For the avoidance of doubt, any prorating in the subsequent offer period will apply only to the pool of Euronext shares tendered during such subsequent offering period.

The Merger

Consideration to NYSE Group Stockholders

As soon as practicable following the settlement and delivery of NYSE Euronext shares and cash upon successful completion of the exchange offer, the combination agreement provides that Jefferson Merger Sub, Inc., a newly formed, wholly owned subsidiary of NYSE Euronext, will merge with NYSE Group. We refer to this as the "merger." In the merger, each outstanding share of NYSE Group common stock will be converted into the right to receive one share of NYSE Euronext common stock. Upon completion of the merger, the surviving corporation, which will be named "NYSE Group" will be a wholly owned subsidiary of NYSE Euronext.

The exchange ratio for NYSE Group stockholders is fixed and will not be adjusted to reflect stock price changes prior to the date of the combination. Each share of NYSE Group common stock owned by

131

NYSE Group (other than any shares held on behalf of third parties) will be cancelled without consideration.

At the time of completion of the merger, each outstanding option to purchase shares of NYSE Group common stock granted under the employee or director stock plans of NYSE Group, whether or not vested, will be converted into an option to acquire an equivalent number of shares of NYSE Euronext common stock at an equivalent exercise price (to be determined in a manner consistent with the requirements of the Internal Revenue Code). In all other respects, each NYSE Group option will continue to be governed by the same terms and conditions as were applicable to it immediately prior to the completion of the merger.

In addition, at the time of completion of the merger, each outstanding restricted stock unit or deferred stock unit measured in shares of NYSE Group common stock, whether vested or unvested, will cease to represent a restricted stock unit or deferred stock unit with respect to shares of NYSE Group common stock and shall be converted, at the time of completion of the merger, into a restricted stock unit or deferred stock unit with respect to NYSE Euronext common stock, on the same terms and conditions as were applicable immediately prior to such conversion.

Procedures for Converting NYSE Group Shares into Merger Consideration

Conversion and Exchange of Shares. The conversion of shares of NYSE Group common stock into the right to receive shares of NYSE Euronext common stock will occur automatically at the effective time of the merger. As soon as practicable after the completion of the merger, [ • ], which will serve as the exchange agent, will exchange former shares of NYSE Group common stock for shares of NYSE Euronext common stock pursuant to the terms of the combination agreement.

NYSE Group Letter of Transmittal. As soon as practicable after the completion of the merger, [ • ], the exchange agent, will send a NYSE Group letter of transmittal to former holders of record of NYSE Group common stock. The NYSE Group letter of transmittal will be accompanied by instructions on how to authorize the transfer and cancellation of NYSE Group common stock held in book-entry form. When the stockholder delivers a properly executed NYSE Group letter of transmittal and any other required documents to the exchange agent, the shares of NYSE Group common stock held by the stockholder automatically will be cancelled and converted into shares of NYSE Euronext common stock, except that the stockholder will be entitled to cash in lieu of fractional shares as described below under "The Combination Agreement—No Fractional Shares."

No interest will be paid or accrued on any amount payable upon such transfer or cancellation of any interest in NYSE Group common stock held in book-entry form. In the event of a transfer of ownership of NYSE Group common stock that is not registered in the transfer records of NYSE Group, the proper number of shares of NYSE Euronext common stock may be issued to such a transferee if written instructions authorizing the transfer of such book-entry interest are presented to the exchange agent, in any case, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. If any shares of NYSE Euronext common stock to be issued in a name other than that in which any book-entry interest of NYSE Group common stock is registered, it shall be a condition of such exchange that the person requesting such exchange shall pay any transfer or other taxes required by reason of the issuance of shares of NYSE Euronext common stock in a name other than that of the registered holder of any book-entry interest of NYSE Group common stock, or shall establish to the satisfaction of NYSE Euronext or the exchange agent that such tax has been paid or is not applicable.

Treatment of Euronext Stock Options and Stock-Based Awards

Treatment in the Exchange Offer

Holders of exercisable Euronext stock options and stock options under Euronext Paris' legacy option plan (the "SBF Option Plan") that would like to tender the Euronext shares underlying such options into the exchange offer must first exercise or subscribe the options and then tender the underlying Euronext shares on or prior to the expiration date of the exchange offer or the subsequent offering period, if any, according to the instructions given in this document and the transmittal materials.

132

As of the date of this document, in accordance with the provisions of the stock option plans, only options granted under Euronext's SBF Option Plan or Euronext's 2001 and 2002 Option Plans are exercisable.

However, if following and as a result of the exchange offer, NYSE Euronext acquires the control of Euronext, stock options granted under Euronext's 2004 Option Plan would become automatically exercisable during a six-month period following the date as of which control is acquired in accordance with the provisions of article 14 of the relevant plan. Option holders would be entitled to tender the underlying Euronext shares to the exchange offer during the subsequent offer period, provided that they timely exercise the options and tender the underlying Euronext shares on or prior to the expiration date of the subsequent offer period.

Holders of stock-based awards granted under the Euronext 2005 and 2006 Executive Inventive Plan and 2006 Euronext All Employee Share Purchase and Match Plan (including, for the avoidance of doubt, its French branch the "Elements Plan") will not be entitled to tender the Euronext shares underlying their stock-based awards into the exchange offer.

Treatment of Euronext Stock Options and Stock-Based Awards Following the Exchange Offer

On the date that the merger is completed, or to the extent not feasible on such date for some or all holders (for tax reasons or otherwise), promptly thereafter and in any event no later than the completion of the post-closing reorganization, each Euronext option, restricted share, restricted stock unit or deferred stocks unit measured in Euronext shares, including for the avoidance of doubt, the stock-based awards granted under the Euronext 2005 and 2006 Executive Incentive Plan and 2006 Euronext All Employee Share Purchase and Match Plan granted under the employee and director stock option and stock-based award plans of Euronext, whether vested or unvested, shall cease to represent a Euronext stock option, restricted share, restricted stock unit or deferred stock unit, as applicable, and shall be converted into a NYSE Euronext stock option stock (a "NYSE Euronext stock option") or a restricted share, restricted stock unit or deferred stock unit respectively, on the same terms and conditions as were applicable under such Euronext stock option, restricted share, restricted stock unit or deferred stock unit (or, if necessary or desirable for tax or other reasons, will be subject to such other arrangement to which the parties shall mutually agree prior to the filing of the exchange offer with the AMF).

The number of shares of NYSE Euronext common stock subject to each such NYSE Euronext stock option, restricted share, restricted stock unit or deferred stock unit shall be the number of Euronext shares subject to the applicable Euronext stock option, restricted share, restricted stock unit or deferred stock unit multiplied by the stock election amount (which is the number of shares of NYSE Euronext common stock that a Euronext shareholder who made the stock election in the offer would have received in the exchange offer, assuming no proration or other adjustments), rounded, if necessary, to the nearest whole share of NYSE Euronext common stock. Such NYSE Euronext stock option shall have an exercise price per share (rounded to the nearest one-hundredth of a cent) equal to the per share exercise price specified in such Euronext stock option divided by the stock election amount (assuming no proration or other adjustments).

Specific Provisions Applicable to French Holders

In certain circumstances, NYSE Euronext will provide separate arrangements for the conversion of Euronext stock options and Euronext stock-based awards held by French residents for tax purposes ("French Holders") in order to allow them to avoid incurring incremental French taxes. Specifically, in the combination agreement, the parties agreed that, if it is reasonably foreseeable that the conversion of any of the Euronext stock options or Euronext stock-based awards would cause French Holders to incur additional French taxes or social security charges, as compared to what they would incur pursuant to the first sentence of Article 200 A 6 of the French General Tax Code if they had converted their Euronext stock options after holding such options for four years from the date of grant, or as compared to what they

133

would incur pursuant to Article 200 A 6 bis of the French General Tax Code if they had converted their Euronext stock-based awards into Euronext shares after holding such stock-based awards for the applicable vesting period and after holding the Euronext shares resulting from such vesting for two years (the "Favorable Tax Amount"), then NYSE Euronext or its subsidiary will offer to the French Holders the right to participate in certain equity arrangements. Under these equity arrangements, NYSE Euronext will undertake to each French Holder that is a party to the equity arrangement to exchange such holder's Euronext shares purchased, subscribed or received pursuant to the Euronext stock options or Euronext stock-based awards after the completion of the exchange offer for a number of shares of NYSE Euronext common stock equal to the stock election amount (assuming no pro-ration or other adjustments). This arrangement, however, will not limit or prohibit NYSE Euronext from undertaking the post-closing reorganization in the time or manner that it shall determine, subject to the requirements set forth in the combination agreement.

In the event that NYSE Euronext undertakes a post-closing reorganization that:

•: results in the termination of the equity arrangements;
•: prevents Euronext from issuing Euronext shares upon exercise of the Euronext stock options or Euronext stock-based awards; or
•: causes French Holders to incur French taxes in an amount greater than the Favorable Tax Amount in respect of such Euronext stock options or Euronext stock-based awards

then the outstanding Euronext stock options and Euronext stock-based awards held by the French Holders will be converted into NYSE Euronext stock options and NYSE Euronext stock-based awards as described above, and NYSE Euronext will pay to each such French Holder (or pay to the applicable Tax authority if required by applicable law) a cash gross-up payment equal to the difference between (1) the aggregate amount of French taxes and social security charges imposed on such French Holder that arises as a result of the post-closing reorganization, if any, minus (ii) the aggregate Favorable Tax Amount that such French Holders would have incurred with respect to its Euronext stock options and/or Euronext stock-based awards after holding such Euronext stock options and/or Euronext stock-based awards (or the resulting shares) for the period from the date of grant necessary to qualify for taxation based on the Favorable Tax Amount. In addition, NYSE Euronext will pay to each such French Holder (or pay to the applicable Tax authority if required by applicable law) an amount of cash equal to the aggregate French taxes incurred by such French Holder as a result of the gross-up payment and the payments pursuant to this sentence. In no event, however, will NYSE Euronext make any gross-up payment or any other payment pursuant in respect of:

•: Euronext stock options originally granted under Euronext's SBF Option Plan or Euronext's 2002 Option Plan or any other Euronext stock options that were granted on a date that is four or more years prior to the date on which a conversion of such options occurs; or
•: a Euronext stock-based award granted on a date that is granted prior to 2005.

French Holders should refer to the French tender offer documents for further information.

Tax Neutrality

NYSE Group, NYSE Euronext and Euronext have agreed to cooperate and use reasonable best efforts to cause, where possible, the conversion of all Euronext stock options and Euronext stock-based awards into NYSE Euronext options or NYSE Euronext stock-based awards (as applicable) as set forth above not to be a taxable transaction for the holders of these Euronext stock options or Euronext stock-based awards; provided that nothing in these provisions shall (A) limit or prohibit NYSE Euronext from undertaking the post-closing reorganization in the time or manner that NYSE Euronext shall determine, subject to the requirements described hereinabove, or (B) subject to the specific provisions applicable to French Holders, require NYSE Euronext to compensate any holder of a Euronext stock option or

134

Euronext stock-based award for any taxes or social security charges incurred or borne by such holder. Any adjustment to Euronext stock options or stock-based awards shall comply with the requirements of Section 409A of the Internal Revenue Code, to the extent applicable.

Post-Closing Reorganization

Consideration Offered to Euronext Shareholders

Following the successful completion of the exchange offer and merger, NYSE Euronext intends to effect a post-closing reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. In the post-closing reorganization, Euronext shareholders who did not exchange their Euronext shares in the exchange offer will generally be provided with the same consideration that they would have received had they tendered their Euronext shares in the exchange offer and not made the cash election or the stock election; that is, €21.32 in cash and 0.98 of a share of NYSE Euronext common stock per Euronext share. Although the structure of the post-closing reorganization may not be determined until after the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer. For more information on the Dutch tax consequences associated with the post-closing reorganization, see "The Combination—Material Dutch Tax Consequences—Post-Closing Reorganization Effectuated Other than Pursuant to the Compulsory Acquisition Procedure—Dividend Withholding Tax."

In the event that 95% or more of the issued and outstanding share capital of Euronext is tendered in the exchange offer, NYSE Euronext may at its option effectuate the post-closing reorganization by initiating a compulsory acquisition procedure (uitkoopregeling) in accordance with section 2:92a of the Dutch Civil Code. In such circumstances, the price to be paid for such shares would be paid in cash only, in an amount determined by the Enterprise Chamber of the Amsterdam Court of Appeals, which amount may be substantially different than the consideration that Euronext shareholders received in the exchange offer.

The effect of the post-closing reorganization will be to eliminate any minority shareholder interest in Euronext remaining after the completion of the exchange offer and will result in Euronext being a wholly owned subsidiary of NYSE Euronext.

Structural Steps to Effect the Post-Closing Reorganization

Certain structural steps that may be needed to effect the post-closing reorganization have been pre-approved by NYSE Group and Euronext.

If 95% or more of the outstanding Euronext shares are acquired by NYSE Euronext after completion of the exchange offer, NYSE Euronext or, if applicable, its wholly owned Dutch subsidiary referred to below, may (i) commence a buyout offer (offer publique de retrait) to acquire Euronext shares from any remaining minority shareholder in accordance with Article 236-1 et seq. of the General Rules of the AMF and any other relevant rules, instructions and/or recommendations of the AMF, and/or (ii) commence a compulsory acquisition by NYSE Euronext, or such subsidiary, of Euronext shares from any remaining minority shareholder in accordance with section 2:92a of the Dutch Civil Code. In the event of a compulsory acquisition in accordance with section 2:92a of the Dutch Civil Code Euronext shareholders would not receive the standard offer consideration. Instead, the price to be paid for such shares would be paid in cash only, in an amount determined by the Enterprise Chamber of the Amsterdam Court of Appeals, which amount may be substantially different from the consideration that Euronext shareholders received in the exchange offer.

135

If less than 95% of the outstanding Euronext shares are acquired by NYSE Euronext or its wholly owned subsidiary after completion of the exchange offer, the post-closing reorganization may be effected as follows:

•

NYSE Euronext or its wholly owned subsidiary may transfer the Euronext shares that it acquired after completion of the exchange offer to a newly formed, direct or indirect wholly owned Dutch subsidiary of NYSE Euronext ("Dutch Holdco") by way of formal or informal capital contribution to Dutch Holdco.

•

Euronext may, and is expected to, transfer all of its assets and liabilities to a newly formed wholly owned Dutch subsidiary of Euronext ("Euronext Sub") by way of formal or informal capital contribution to Euronext Sub or by way of a legal demerger; and

•

one of the following:

•: Euronext may transfer the shares in Euronext Sub to Dutch Holdco in exchange for shares of NYSE Euronext common stock and cash and, then, cause Euronext to distribute such shares of NYSE Euronext common stock and cash to its shareholders in a complete liquidation of Euronext (to the extent that a liquidating distribution would be made to Dutch Holdco, Dutch Holdco may substitute a promissory note for the portion of the consideration payable for the Euronext Sub shares that would be distributed to Dutch Holdco in the liquidation of Euronext); or
•: With the prior written consent of Euronext, which shall not be withheld unless certain specified conditions are met, Euronext may merge with and into a newly formed, wholly owned Dutch subsidiary of Dutch Holdco or NYSE Euronext ("Dutch Mergerco"), pursuant to which the Euronext shareholders will receive shares in Dutch Mergerco; after such merger, NYSE Euronext may cause Dutch Mergerco to transfer the shares in Euronext Sub to Dutch Holdco in exchange for shares of NYSE Euronext common stock and cash and, then, cause Dutch Mergerco to distribute such shares of NYSE Euronext common stock and cash to the Dutch Mergerco shareholders in a complete liquidation of Dutch Mergerco (to the extent that a liquidating distribution would be made to Dutch Holdco, Dutch Holdco may substitute a promissory note for the portion of the consideration payable for the Euronext Sub shares that would be distributed to Dutch Holdco in the liquidation of Dutch Mergerco).

Unless such resolutions are considered and approved, subject to the successful completion of the exchange offer and of the merger, at the Euronext extraordinary meeting, another extraordinary meeting of shareholders of Euronext will be convened after completion of the exchange offer, at which meeting the Euronext shareholders (which at that time will include NYSE Euronext or a wholly owned subsidiary as majority shareholder) will be asked to approve the steps to effect the post-closing reorganization referred to above and to dissolve Euronext (or Dutch Mergerco, as the case may be) and to liquidate its assets.

NYSE Euronext will have the right (subject to any requisite shareholder and regulatory approvals) to change the structure of the post-closing reorganization, which could include, among other things:

•: an amendment of the articles of association of Euronext to permit the creation, among other things, of separate classes of shares;
•: the distribution of an extraordinary dividend on Euronext shares or a particular class or classes of shares of Euronext;
•: the sale and transfer by Euronext, or any of its subsidiaries, to NYSE Euronext or any affiliate or subsidiary of NYSE Euronext, of all or a portion of the assets of Euronext or its subsidiaries;
•: the effectuation by Euronext and one or more Dutch subsidiaries of NYSE Euronext of a legal merger within the meaning of section 2:309 of the Dutch Civil Code;

136

•: the request for termination of the listing of the Euronext shares on Euronext Paris (Eurolist by Euronext);
•: a liquidation of Euronext;
•: the contribution of assets to Euronext in exchange for Euronext shares (with the exclusion of preemptive rights, if any, of other shareholders, all in accordance with applicable law); or
•: any one or more combinations of any of the foregoing actions, all of which shall be conducted in accordance with applicable law.

However, NYSE Euronext will not change the structure of the post-closing reorganization without the prior written consent of Euronext (which consent shall not be withheld unless the Euronext supervisory and managing boards, after consultation with their outside legal counsel, determine in good faith that such consent would result in a breach of its directors' fiduciary duties under applicable law; it being understood that, in making this determination, the Euronext supervisory and managing boards will consider the interests of all shareholders of Euronext to the extent that it considers the interests of any shareholder or group of shareholders of Euronext), and Euronext will have the right to propose alternatives for the post-closing reorganization, which NYSE Euronext and NYSE Group shall consider in good faith.

No Fractional Shares

No person will receive fractional shares of NYSE Euronext common stock in the combination. No NYSE Group stockholder would be entitled to a fraction of a share of NYSE Euronext common stock in the merger because each share of NYSE Group common stock is converted into the right to receive one share of NYSE Euronext common stock in the merger. It is possible, however, for the consideration receivable by a Euronext shareholder to otherwise be a fraction of a share NYSE Euronext common stock since each Euronext share tendered and not withdrawn from the exchange offer will be converted into €21.32 in cash and 0.98 of a share of NYSE Euronext common stock (unless the tendering Euronext shareholder makes the cash election or the stock election). However, in no event will NYSE Euronext issue any fraction of a share of NYSE Euronext common stock. Instead, the NYSE Euronext or its agent will sell, on behalf of Euronext shareholders, the aggregate fractional shares that those holders would otherwise have received in the exchange offer, and each Euronext shareholder that otherwise would have received a fraction of a share of NYSE Euronext common stock will receive cash in an amount equal to the shareholder's proportional interest in the net proceeds of the sale.

Dividends on NYSE Euronext Common Stock; Withholding

Dividends and Distributions with Respect to Unexchanged Shares. Any dividend or other distribution declared after the completion of the combination with respect to shares of NYSE Euronext common stock into which shares of Euronext ordinary shares or NYSE Group common stock are exchangeable as of the post-closing reorganization or the merger, respectively, will not be paid (but will nonetheless accrue) until those shares of common stock are properly surrendered for exchange. NYSE Euronext will pay to tendering Euronext shareholders and former NYSE Group stockholders any unpaid dividends or other distributions, without interest, only after they have duly surrendered their stock certificates or book-entry interests, as applicable. After the completion of the combination, there will be no transfers on the NYSE Group's transfer books of any shares of NYSE Group common stock, that were outstanding immediately prior to the completion of the combination.

Withholding. NYSE Euronext and the exchange agent will be entitled to deduct and withhold from the consideration payable to any tendering Euronext shareholder or former NYSE Group stockholder the amounts that they are required to deduct and withhold under the Internal Revenue Code or any provision of any state, local or non-U.S. tax law. If the exchange agent withholds any amounts, these amounts will be treated for all purposes of the combination agreement as having been paid to the stockholders from whom they were withheld.

137

Additional Reciprocal Conditions. In addition to the above, the combination agreement provides that NYSE Euronext shall not file or commence the exchange offer unless each of the following conditions have been satisfied (or waived by NYSE Group or Euronext, as applicable):

138

•: the representations and warranties of NYSE Group and Euronext relating to capitalization and authority shall be true and accurate in all material respects, and the other representations and warranties of NYSE Group and Euronext shall be true and accurate, subject to exceptions that, individually or in the aggregate, do not have, and would not reasonably be expected to have, a material adverse effect on it or its subsidiaries;
•: NYSE Group and Euronext shall each have performed in all material respects with each of its agreements and covenants required to be performed by it under the combination agreement; and
•: the NYSE Group board of directors and the Euronext managing and supervisory boards shall not have withdrawn or changed its/their recommendation in favor of the combination agreement and the combination, approved an acquisition proposal other than the combination of the foregoing or taken a neutral position or made no recommendation following receipt of such an acquisition proposal.

For purposes of the combination agreement, the term "material adverse effect" means, with respect to either party, a material adverse effect on the business, results of operations or financial condition of NYSE Group or Euronext (as applicable) and their respective subsidiaries (including, in the case of Euronext, certain joint ventures), taken as a whole. The following, however, shall not be considered in determining whether a material adverse effect has occurred:

•: any change or development in economic, business or securities markets conditions generally (including any such change or development resulting from acts of war or terrorism) to the extent that such change or development does not affect NYSE Group or Euronext and their respective subsidiaries (including, in the case of Euronext, certain joint ventures), taken as a whole, in a materially disproportionate manner relative to other securities exchanges or trading markets;
•: any change or development to the extent resulting from the execution or announcement of the combination agreement or the transactions contemplated by the combination agreement; or
•: any change or development to the extent resulting from any action or omission by NYSE Group or Euronext and their respective subsidiaries (including, in the case of Euronext, certain joint ventures) that is required by the combination agreement.

Additional NYSE Group Conditions. NYSE Euronext will not file or commence the exchange offer unless each of the following additional conditions is satisfied (or waived by NYSE Group):

•: NYSE Group shall have received a supplemental private letter ruling from the U.S. Internal Revenue Service or a tax opinion from Wachtell Lipton, counsel to NYSE Group, in either case substantially to the effect that the consummation of the exchange offer and the merger will not adversely affect the previously obtained Internal Revenue Service letter ruling regarding the demutualization of the NYSE and its merger with Archipelago; and
•: NYSE Group shall have received a tax opinion from Wachtell Lipton, dated as of the date of filing the exchange offer, to the effect that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code.

Conditions to Completing the Exchange Offer

Minimum Tender Condition. NYSE Euronext will not be obligated to purchase any tendered Euronext shares pursuant to the exchange offer unless Euronext shares representing at least two-thirds of the outstanding Euronext shares as of the closing of the exchange offer are validly tendered and not withdrawn in the exchange offer. This document refers to this condition as the "minimum tender condition."

After consultation with Euronext, NYSE Euronext may change the minimum tender condition so that it is not less than a majority of the Euronext shares and not less than a majority of the Euronext voting

139

power, in each case outstanding on a fully diluted basis as of the closing of the exchange offer, as it may be extended in accordance with applicable laws. Neither NYSE Euronext nor holders of Euronext shares will know whether the minimum tender condition has been satisfied until the preliminary results of the exchange offer are published by the AMF following the expiration date or the exchange offer. The definitive results should be published within nine days of the closing of the exchange offer.

Article 232-11 of the General Rules of the AMF. The successful completion of the exchange offer will also be subject to the condition that NYSE Euronext shall not have withdrawn the exchange offer in accordance with the provisions of Article 232-11 of the General Rules of the AMF. NYSE Euronext has the right to withdraw the exchange offer in the following two circumstances:

•: within five French trading days following the date of the publication by the AMF of the timetable for a competing or an improved offer for Euronext by a competing bidder if the Euronext supervisory or managing board has changed its recommendation for the combination or taken any of the other actions referred to in Paragraph II(c) of Annex II of the combination agreement; or
•: with the prior approval of the AMF if, prior to the publication by the AMF of the definitive results of the exchange offer, Euronext adopts definitive measures that modify Euronext's substance (modifiant sa consistance) or if the exchange offer becomes irrelevant (sans objet) under French law.

The terms "modifiant sa consistance" and "sans objet" are subject to interpretation by the AMF. NYSE Euronext believes that the terms "modifiant sa consistance" is generally understood to refer to measures taken by a target company following a launch of a tender offer for its securities, such as the sale of material business segments, which result in a significant change in the target company's business operations. NYSE Euronext believes that the term "sans objet" is generally understood to refer to an offer that become irrelevant and loses its purpose when, for example, an offeror launches a separate, revised offer for the target company.

Under French law, if, during the period of the exchange offer, another offer for Euronext is approved by the AMF, all Euronext shareholders' previous tenders of Euronext shares will be declared null and void by the AMF at the latest upon the opening of such offer. In addition, if an improved offer by a competing bidder is approved by the AMF, all Euronext shareholders' previous tenders of Euronext shares may also be declared null and void by the AMF. In each of these events, in order to tender Euronext shares in the exchange offer, if the exchange offer remains outstanding, the Euronext shareholder will be required to re-tender the Euronext shares.

If the AMF's decision to approve the exchange offer and the exchange offer documentation is declared null and void by a competent French court or if the minimum tender condition is not satisfied as shown by the definitive results of the offer to be published by the AMF, the exchange offer will lapse. If the exchange offer lapses, NYSE Euronext reserves the right to commence a new offer or not, in its sole discretion. In addition, if the exchange offer lapses, the Euronext shares that a Euronext shareholder tendered in the exchange offer will be returned to the shareholder without interest or any other payment being due. This should occur within two French trading days following the date upon which the offer has lapsed.

Conditions to Completing the Merger

The only condition to the completion of the merger is the successful completion of the exchange offer.

Reasonable Best Efforts to Obtain Required Approvals

NYSE Euronext, NYSE Group and Euronext have each agreed to use reasonable best efforts to take all actions necessary to consummate the exchange offer, the merger, and the other transactions contemplated by the combination agreement as soon as practicable, including taking such actions

140

necessary to obtain any required consents from third parties or governmental authorities. However, the combination agreement does not require NYSE Group or Euronext to:

•: agree to sell or hold separate and agree to sell, or take any other action with respect to, any assets or businesses of NYSE Euronext, NYSE Group, Euronext or any of their respective subsidiaries or affiliates if this action, individually or in the aggregate, would reasonably be expected to result in substantial detriment to NYSE Euronext, NYSE Group, Euronext or any of their respective subsidiaries, taken as a whole; or
•: agree to any changes or restrictions in the market or regulatory structure of NYSE Euronext, NYSE Group, Euronext or any of their respective subsidiaries or affiliates, or in the operations of their respective assets and business, that would, individually or in the aggregate, reasonably be expected to result in a substantial detriment to NYSE Euronext, NYSE Group, Euronext or any of their respective subsidiaries, taken as a whole.

For purposes of the combination agreement, the term "substantial detriment" means a material adverse effect on:

•: with respect to any of NYSE Euronext, NYSE Group, Euronext or their respective subsidiaries, the business, continuing results of operations or financial condition of NYSE Euronext, NYSE Group, Euronext or any of their respective subsidiaries, in each case taken as a whole;
•: with respect to NYSE Euronext or NYSE Group, the authority or ability of NYSE LLC or NYSE Arca, Inc. to continue as a national securities exchange; or
•: with respect to Euronext, the authority or ability of Euronext Paris, Euronext Amsterdam, Euronext Lisbon, Euronext Brussels or LIFFE Administration and Management to continue to operate the markets that they currently operate.

Third-Party Acquisition Proposals

The combination agreement contains detailed provisions outlining the circumstances in which NYSE Group and Euronext may respond to acquisition proposals received from third parties. Under these provisions, each of NYSE Group and Euronext has agreed not to:

•: initiate, solicit, knowingly encourage (including by way of furnishing information), facilitate or induce any inquires or the making, submission or announcement of any proposal or offer that contributes to, or could reasonably be expected to result in, an "acquisition proposal" (as described below);
•: subject to applicable law after consultation with outside counsel, hold any discussions with or provide any confidential information or data to any person or entity relating to an acquisition proposal, or engage in any negotiations concerning an acquisition proposal, or knowingly facilitate any effort or attempt to make or implement an acquisition proposal;
•: approve or recommend, or propose publicly to approve or recommend, any acquisition proposal; or
•: approve or recommend, or propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement related to any acquisition proposal or propose publicly or agree to do any of the foregoing.

If Euronext receives an unsolicited bona fide written acquisition proposal for Euronext at any time prior to the completion of the exchange offer, or if NYSE Group receives an unsolicited bona fide written acquisition proposal for NYSE Group prior to the receipt of NYSE Group stockholder approval of the combination agreement, the party receiving that proposal may engage in discussions or negotiations with,

141

or provide information to the person or entity making that acquisition proposal, if and only to the extent that:

•: the Euronext supervisory and managing boards (in the case of a proposal for Euronext) determines in good faith, or the NYSE Group board of directors (in the case of a proposal for NYSE Group) determine in good faith, in each case after consultation with its outside counsel and financial advisors, that:
•: there is a reasonable likelihood that the acquisition proposal could constitute a "superior proposal" (as described below); and
•: such action is necessary in order for the directors to comply with their fiduciary duties under applicable law;
•: prior to providing any information or data to any person in connection with the acquisition proposal, the Euronext supervisory or managing boards, or NYSE Group board of directors, as applicable, receives or receive, as applicable, from the person making the acquisition proposal an executed confidentiality agreement, with terms that are no less restrictive, in the aggregate, than those contained in the confidentiality agreement between NYSE Group and Euronext; and
•: the party receiving the acquisition proposal is not then in material breach of the "no solicitation" provisions in the combination agreement.

In addition, if Euronext receives an unsolicited bona fide written acquisition proposal for Euronext prior to the completion of the exchange offer, or if NYSE Group receives an unsolicited bona fide written acquisition proposal for NYSE Group prior to the receipt of NYSE Group stockholder approval of the combination agreement, then the party receiving that proposal may withdraw or change its recommendation in favor of adopting the combination agreement or, in the case of Euronext, in favor of the exchange offer and the transactions contemplated by the combination agreement if and only to the extent that:

•: the Euronext supervisory and managing boards (in the case of a proposal for Euronext), determine in good faith, or the NYSE Group board of directors (in the case of a proposal for NYSE Group) determines in good faith, in each case after consultation with outside counsel and financial advisors, that:
•: the acquisition proposal which has been received constitutes a superior proposal (as described below); and
•: such action is necessary in order for the directors to comply with their respective fiduciary duties under applicable law.

The combination agreement permits NYSE Group and its board of directors to comply with Rule 14d-9 and Rule 14e-2 under the Exchange Act, and permits Euronext and its managing and supervisory boards to comply with Article 231-21 of the General Rules of the AMF, in each case with regard to an acquisition proposal that either party may receive and to make other disclosures required by law or the fiduciary duties of the NYSE Group board of directors or the Euronext supervisory and managing boards, as applicable.

142

For purposes of the combination agreement, the term "acquisition proposal" means, with respect to either NYSE Group or Euronext, any proposal or offer with respect to, or any indication of interest in:

•: any direct or indirect acquisition or purchase of Euronext or NYSE Group or any of their respective subsidiaries that constitutes 10% or more of the consolidated gross revenue or consolidated gross assets of Euronext or NYSE Group, as applicable, and their respective subsidiaries, taken as a whole;
•: any direct or indirect acquisition or purchase of 10% or more of any class of equity securities or voting power or 10% or more of the consolidated gross assets of Euronext or NYSE Group, as applicable; or 50% or more of any class of equity securities or voting power of any of their subsidiaries that constitutes 10% or more of the consolidated gross revenue or consolidated gross assets of Euronext or NYSE Group and their respective subsidiaries, taken as a whole;
•: any tender offer that, if completed, would result in any person beneficially owning 10% or more of any class of equity or voting power of Euronext or NYSE Group; or
•: any merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving Euronext or NYSE Group or any of their respective subsidiaries that constitutes 10% or more of the consolidated gross revenue or consolidated gross assets of Euronext or NYSE Group and their respective subsidiaries, taken as a whole.

For purposes of the merger agreement, "superior proposal" means a bona fide written acquisition proposal obtained by either NYSE Group or Euronext (other than any such proposal obtained in breach of the "no solicitation" provisions in the combination agreement) for or in respect of:

•: 50% or more of the outstanding NYSE Group common stock or Euronext shares (as applicable); or
•: 50% or more of the assets of NYSE Group or Euronext and their respective subsidiaries, on a consolidated basis;

on terms that the NYSE Group board of directors concludes or the Euronext supervisory and managing boards conclude, as applicable, in good faith, after receipt of the advice of their respective financial advisors and outside legal counsel, are more favorable, from a financial point of view, to the stockholders and other stakeholders of Euronext or to the stockholders of NYSE Group, as applicable, than the combination contemplated by the combination agreement, after taking into account, among other things, legal, financial, regulatory, timing and other aspects of the acquisition proposal and the combination agreement and any improved terms that the other party has offered pursuant to the combination agreement that are deemed relevant by the NYSE Group board of directors, in the case of NYSE Group, or the Euronext managing and supervisory boards, in the case of Euronext, including conditions to and the expected timing and risks of completion and the ability of the party making the acquisition proposal to obtain financing.

NYSE Group and Euronext have agreed in the combination agreement that:

•: they will provide oral or written notice to the other party within two business days of receipt of any acquisition proposal or any request for nonpublic information or inquiry that the party receiving the acquisition proposal, request or inquiry reasonably believes could lead to an acquisition proposal, of the material terms and conditions of the acquisition proposal, request or inquiry and the identity of the person making the acquisition proposal, request or inquiry;
•: they will thereafter provide the other party, as promptly as practicable, with oral and written notice containing sufficient information to keep the other party informed in all material respects of the status and details of the acquisition proposal, request or inquiry;

143

•: they will notify the other party in writing at least four business days prior to changing its recommendation in favor of adopting the combination agreement. The party receiving the acquisition proposal will consider any modification to the terms of the combination agreement that are proposed by the other party following receipt of such notification in determining if the acquisition proposal still constitutes a superior proposal;
•: in the event that a third party who has previously made an acquisition proposal that NYSE Group or Euronext has determined is a superior proposal subsequently modifies or amends in an adverse manner any material term of such superior proposal, then such party's prior determination that such proposal is a superior proposal shall be null and void and such party shall be required to comply with the "no solicitation" provisions of the combination agreement; in respect of such modified acquisition proposal; and
•: except as ordered by a court or shareholder action, each party will, and will cause its senior officers, directors and representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of the combination agreement with any persons or entities with respect to any acquisition proposal.

Stockholders' Meetings

NYSE Group Special Meeting. NYSE Group agreed in the combination agreement to convene a meeting of its stockholders on a date determined by NYSE Group, after consultation with Euronext, that shall be as promptly as practicable after the registration statement of which this document forms a part is declared effective; provided that, after consultation with Euronext, NYSE Group may convene its stockholder meeting after the SEC has granted any necessary approvals for the consummation of the transactions contemplated by the combination agreement. Additionally, subject to fiduciary obligations under applicable law, the NYSE Group board of directors agreed to recommend and solicit the approval and adoption of the combination agreement. In the event that the NYSE Group board of directors determines that the combination agreement is no longer advisable and either (1) makes no recommendation or (2) recommends that its stockholders reject the combination agreement, in each case in compliance with its "no solicitation" obligations, Euronext will have the right to terminate the combination agreement.

Euronext Extraordinary Meeting. Similarly, Euronext agreed in the combination agreement to convene a meeting of its shareholders on a date determined by Euronext, after consultation with NYSE Group, that shall be as promptly as practicable after the shareholder circular for the Euronext extraordinary meeting is completed, to vote on whether to approve the combination agreement and the transactions contemplated thereby (and consider any other matters properly brought before the meetings). Additionally, subject to fiduciary obligations under applicable law, the Euronext managing and supervisory boards agreed to recommend and solicit the approval of the exchange offer and recommend that the shareholders tender their shares. In the event that the Euronext supervisory and managing boards determine that the combination agreement is no longer advisable and either (1) make no recommendation or (2) recommend that Euronext shareholders not tender their shares, in each case in compliance with their "no solicitation" obligations, NYSE Group will have the right to terminate the combination agreement.

Termination

Termination Rights

NYSE Group and Euronext may terminate the combination agreement at any time prior to the filing of the exchange offer with the AMF by mutual consent. In addition, either NYSE Group or Euronext may

144

terminate the combination agreement by written notice to the other party at any time prior to the filing of the exchange offer with the AMF if:

•: the filing of the exchange offer with the AMF shall not have occurred on or before January 31, 2007 (the "termination date"), except that this right to terminate will not be available to a party whose failure to comply, in any material respect, with any provision of the combination agreement (or similar failure by any of the party's subsidiaries) proximately contributed to the failure of the exchange offer being filed;
•: the NYSE Group stockholders do not approve and adopt the combination agreement and the merger at NYSE Group's stockholder meeting;
•: the Euronext shareholders do not approve the exchange offer and the transactions contemplated by the combination agreement at the Euronext extraordinary meeting; or
•: any governmental entity or SRO denies any regulatory approval that is required to be obtained in connection with the combination, and this denial becomes final, binding and non-appealable, or if any governmental entity or SRO issues a final and non-appealable order permanently restraining, enjoining or otherwise prohibiting the combination.

The termination date of the combination agreement set forth above may be extended by either party to March 31, 2007 if, on January 31, 2007, the only condition to the completion of the combination that have not yet been satisfied is the receipt of certain regulatory approvals including those listed in "The Combination—Regulatory Approvals."

Either party may also terminate the combination agreement at any time prior to the filing of the exchange offer with the AMF if:

•: the board of directors of NYSE Group in the case of Euronext or the managing and supervisory boards of Euronext in the case of NYSE Group, change their recommendation for the combination or fail to reconfirm their recommendation within ten business days after a written request by the other party to do so;
•: the other party breaches in any material respect any of its representations, warranties, covenants or agreements contained in the combination agreement (which breach would prevent satisfaction of the other party's relevant closing conditions), and the breach is not curable or if curable, is not cured prior to the earlier of (1) the date that is 30 days after written notice of the breach is given, or (2) the business day prior to the termination date of the combination agreement); or
•: the other party breaches in any material respect the "no solicitation" provisions described under "The Combination Agreement—Third-Party Acquisition Proposals."

The combination agreement can be terminated by either party after the filing of the exchange offer with the AMF if the period of the exchange offer has expired, and the minimum tender condition has not been satisfied.

In addition, the combination agreement can be terminated by NYSE Group after the filing of the exchange offer with the AMF if:

•: NYSE Euronext withdraws the exchange offer in accordance with paragraph 2 of Article 232-11 of the General Rules of the AMF; or
•: (1) a third party has launched a competing bid (or an improved offer after previously launching a competing bid) for the Euronext shares and NYSE Euronext has decided to exercise its right of withdrawal pursuant to paragraph 1 of Article 232-11 of the General Rules of the AMF and (2) the managing and supervisory boards of Euronext have changed their recommendation for the combination.

145

Expense Reimbursement

Expense Reimbursement by NYSE Group. The combination agreement requires NYSE Group to reimburse Euronext for its out-of-pocket costs, fees and expenses incurred in connection with the transactions contemplated by the combination agreement if:

•: Euronext terminates the combination agreement because the NYSE Group stockholders did not approve the merger and other transactions contemplated by combination agreement; or
•: Euronext terminates the combination agreement because the NYSE Group board of directors has changed its recommendation or failed to reconfirm its recommendation for the combination as described above.

Expense Reimbursement by Euronext. The combination agreement requires Euronext to reimburse NYSE Group for its out-of-pocket costs, fees and expenses incurred in connection with the transactions contemplated by the combination agreement if:

•: NYSE Group terminates the combination agreement because the Euronext shareholders did not approve the exchange offer and other transactions contemplated by the combination agreement;
•: NYSE Group terminates the combination agreement because the Euronext supervisory and managing boards have changed their recommendations or failed to reconfirm their recommendations for the combination as described above;
•: NYSE Group terminates the combination agreement because the period of the exchange offer has expired, and the minimum tender condition has not been satisfied;

This payment was made on August 11, 2006 to Euronext shareholders. The repayment of €3 per share will not reduce the consideration offered by NYSE Euronext in the exchange offer.

Indemnification and Insurance of Directors and Officers

The parties agreed that, after the completion of the combination, NYSE Euronext will indemnify, hold harmless and provide advancement of expenses to the past and present directors, officers and employees of NYSE Group, Euronext and their respective subsidiaries, for acts or omissions occurring at or prior to the completion of the combination, to the same extent as these individuals had rights of indemnification prior to the completion of the combination and to the fullest extent permitted by law. The parties also agreed that the NYSE Euronext certificate of incorporation and bylaws will include provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses that are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions in the current certificate of incorporation and bylaws of each of NYSE Group and Euronext.

In addition, for a period of six years following the successful completion of the combination, NYSE Euronext will maintain in effect the current directors' and officers' and fiduciary liability policies maintained by each of NYSE Group and Euronext with respect to claims arising from facts or events occurring at or prior to the completion of the combination (or a substitute policy or policies with the same coverage and with terms no less advantageous in the aggregate), subject to the limitation that NYSE Euronext will not be required to spend in any one year more than 250% of the annual premiums currently paid by NYSE Group and Euronext, respectively, for this insurance. Instead, NYSE Euronext may, at its option, purchase a six-year "tail" prepaid policy on the same terms and conditions and subject to the same expenditure limitation.

148

Governance and Management

Upon completion of the combination, the NYSE Euronext board of directors will consist of 22 directors, 12 of whom will be the directors of NYSE Group immediately prior to the combination, 9 of whom will be members of the Euronext supervisory board immediately prior to the combination and 1 of whom will be the chief executive officer of Euronext immediately prior to the combination. The initial term of the directors will end with the first annual stockholders meeting to be held by NYSE Euronext. Thereafter, the directors will serve one-year terms. The directors that NYSE Group and Euronext expect to be on the NYSE Euronext board of directors immediately after completion of the combination, along with their relevant biographical information, are set forth under "Directors and Management of NYSE Euronext After the Combination." All members of the NYSE Euronext board of directors, other than the chief executive officer and deputy chief executive officer of NYSE Euronext, must satisfy the NYSE Euronext independence requirements for directors.

The combination agreement also provides that John A. Thain, the current chief executive officer and a director of the NYSE Group, will be the chief executive officer and a director of NYSE Euronext. Jan-Michiel Hessels, the current chairman of the Euronext supervisory board, will be the chairman of NYSE Euronext. Jean-François Théodore, the current chief executive officer of Euronext, will be the deputy chief executive officer and a director of NYSE Euronext. Marshall N. Carter, the current chairman of NYSE Group, will be the deputy chairman of NYSE Euronext.

The NYSE Euronext bylaws will provide that the NYSE Euronext board of directors will be composed of 12 persons who are U.S. domiciliaries and 10 persons who are European domiciliaries. In addition, the bylaws will provide that the nominating and governance committee of the NYSE Euronext board of directors will be composed of an equal number of individuals who are U.S. domiciliaries and European domiciliaries. Further, the bylaws will provide that the positions of chairman of the board of directors and chief executive officer of NYSE Euronext will be filled by one person who is a U.S. domiciliary and one person who is a European domiciliary. These requirements cannot be changed unless approved by a resolution adopted by two-thirds of the directors then in office or a shareholder vote of 80% of the shares issued and outstanding.

The management committee of NYSE Euronext will have up to 16 members, including an equal number of NYSE Group designees and Euronext designees.

Amendment and Waiver

NYSE Group and Euronext may amend the combination agreement at any time before or after approval and adoption of the combination agreement by the NYSE Group stockholders or Euronext shareholders. However, after approval and adoption of the combination agreement, no amendment may be made which by law or in accordance with the rules of any relevant stock exchange requires further approval by those stockholders unless this further approval is obtained. An example of an amendment that would not require further approval by NYSE Group stockholders or Euronext shareholders is a technical amendment to the combination agreement that does not change the amount or the form of the consideration to be delivered to NYSE Group stockholders or the Euronext shareholders in the combination, such as an amendment to the interim operating covenants in the combination agreement. In the event that NYSE Group and Euronext authorize an amendment to the combination agreement that does not require further approval by NYSE Group stockholders or Euronext shareholders, NYSE Group and Euronext will inform NYSE Group stockholders and Euronext shareholders of such amendment by press release and other public communication. In the event that NYSE Group and Euronext authorize an amendment to the combination agreement that requires further approval by NYSE Group stockholders or Euronext shareholders, another proxy statement/prospectus would be delivered to NYSE Group stockholders and Euronext shareholders, and proxies would be re-solicited for approval of such amendment.

149

At any time before the completion of the combination, the parties may, to the extent legally allowed, waive any compliance with any of the conditions contained in the combination agreement.

Sir Brian Williamson

Sir Brian has been a member of the supervisory board of Euronext since April 18, 2002. Previously, he was chairman of London International Financial Futures & Options Exchange (LIFFE) (United Kingdom), from 1985 to 1988 and from 1998 to 2003 (after the acquisition of LIFFE by Euronext), Member of Court of the Bank of Ireland from 1990 to 1999, director of the Financial Services Authority (United Kingdom) from 1986 to 1998, member and chairman of the International Advisory Board of NASDAQ Stock Market (US) from 1995 to 1998, and Governor-at-Large of the National Association of Securities Dealers (USA) from 1995 to 1998. He was also chairman of Gerrard Group plc (United Kingdom) from 1989 to 1998, and director of Templeton Emerging Markets Investment Trust plc (United Kingdom) from 2002 to 2003. Currently, Sir Brian is also chairman of Electra Private Equity plc (United Kingdom), senior advisor of Fleming Family and Partners (United Kingdom), director of HSBC Holdings plc (United Kingdom), and director of Resolution plc (United Kingdom).

The initial term of these directors will end with NYSE Euronext's first annual stockholders meeting after completion of the combination. Thereafter, the directors will serve for one-year terms. The bylaws of NYSE Euronext provide that in any election of directors, the nominees who will be elected will be the nominees who receive the highest number of votes such that, immediately following the election, (1) persons whose domicile is a European country will constitute the largest number of directors that represents a minority of the total number of directors, and (2) persons whose domicile is the United States will constitute a majority of the directors then in office.

Committees of the NYSE Euronext Board of Directors

Upon completion of the combination, the NYSE Euronext board of directors will initially have the following three committees:

•: an audit committee;
•: a human resources & compensation committee; and
•: a nominating & governance committee.

Each of these committees will comply with the independence requirements of NYSE Euronext. NYSE Euronext's independence requirements will be the same as the current independence requirements of the NYSE Group, except that:

•: the deputy chief executive officer, in addition to the chief executive officer, may serve as a director of NYSE Euronext;
•: with respect to broker-dealers that are not members of the NYSE or NYSE Arca, the independence policy only applies to broker-dealers registered under the Exchange Act or persons employed or affiliated with such broker-dealers, including European affiliates (but not purely non-U.S. broker-dealers); and
•: the independence policy does not per se prohibit executive officers of NYSE-listed and NYSE Arca-listed companies that are "foreign private issuers" (as defined under Rule 3b-4 promulgated under the Exchange Act) from serving as independent directors on the board. However, executive officers of foreign private issuers, together with executive officers of NYSE Euronext or any of its

159

subsidiaries, can constitute no more than a minority of the total number of directors of NYSE Euronext and no more than a minority of the total number of directors of NYSE Group. In addition, an executive officer of an issuer whose securities are listed on the NYSE or NYSE Arca (regardless of whether such issuer is a foreign private issuer) cannot qualify as an independent director of the NYSE, NYSE Market or NYSE Regulation.

The committees will also be independent as defined in the listing standards of the NYSE. For a description of the NYSE Group's current independence requirements for directors, see "Information about NYSE Group—Officers and Directors." As a result, the chief executive officer and deputy chief executive officer of NYSE Euronext will not be permitted to serve on any of NYSE Euronext's committees and will be recused from voting on any matter within the competence of the three committees that comes before the NYSE Euronext board. The NYSE Euronext board of directors will review and amend as necessary the charter for each of these committees annually.

Audit Committee. All members of the audit committee will be financially literate. The audit committee will also contain at least one member who will be considered an audit committee financial expert as defined by the SEC. The responsibilities of the audit committee of NYSE Euronext will include:

•: assisting the board of directors in its oversight of: (a) the integrity of NYSE Euronext's financial statements and internal controls, (b) compliance with legal and regulatory requirements, as well as NYSE Euronext's ethical standards and policies, (c) the qualifications and independence of NYSE Euronext's independent auditor, and (d) the performance of NYSE Euronext's internal audit function and its independent auditors; and preparing the audit committee report for inclusion in NYSE Euronext's annual proxy statement;
•: appointing, terminating and compensating the independent auditor;
•: overseeing the independent auditor's engagement;
•: meeting regularly in separate executive session with the independent and internal auditors;
•: reviewing the independent auditor's reports and the internal auditor's reports with respect to NYSE Euronext's internal controls;
•: approving all audit and non-audit services performed by the independent auditor; and
•: determining the budget and staffing for the corporate audit department of NYSE Euronext.

Human Resources & Compensation Committee. The responsibilities of the human resources & compensation committee of NYSE Euronext will include:

•: reviewing and advising the chairman of the board, the chief executive officer and the other officers of NYSE Euronext with respect to human resource policies and procedures relating to NYSE Euronext;
•: at the request of the nominating & governance committee, advising and assisting the nominating & governance committee in reviewing (i) director compensation and benefits and (ii) any development plans for potential successors to the chief executive officer; reviewing and approving corporate goals and objectives relevant to chief executive officer or deputy chief executive officer; compensation, evaluating the performance of the chief executive officer and deputy chief executive officer in light of those goals and objectives, and, together with the other directors, determining and approving such compensation;
•: at the request of the board, reviewing the appointment of all officers who are subject to Section 16(b) of the Exchange Act, all officers who report directly to the chief executive officer or deputy chief executive officer of NYSE Euronext and recommendations involving personnel received from the audit committee;

160

•: reviewing, approving, and submitting for ratification by the board of directors, the compensation for senior executive officers;
•: approving officers appointed by, and reporting directly or indirectly to, the chief executive officer or deputy chief executive officer of NYSE Euronext;
•: reviewing and approving any employment agreements for senior executives of NYSE Euronext;
•: at the request of the human resources & compensation committee of NYSE Regulation, advising and assisting the human resources & compensation committee of NYSE Regulation concerning human resource policies and procedures and director compensation; and
•: reporting annually to the stockholders and the public on the compensation of the five most highly compensated officers of NYSE Euronext and its subsidiaries (as well as director compensation) and on the compensation philosophy and methodology used to award that compensation (including information relating to appropriate comparisons, benchmarks, performance measures and evaluation processes consistent with the missions of NYSE Euronext and its subsidiaries (including NYSE Regulation)).

Nominating & Governance Committee. The combination agreement provides that as of the completion of the combination, the committee will consist of an equal number of individuals who were directors of NYSE Group and Euronext immediately prior to the combination. The bylaws of NYSE Euronext provide that the committee will be composed of an equal number of U.S. domiciliaries and European domiciliaries. The responsibilities of the nominating & governance committee of NYSE Euronext will include:

•: recommending to the NYSE Euronext board of directors candidates for the NYSE Euronext board of directors, and for positions on the boards of NYSE Euronext operating companies designated for NYSE Euronext directors;
•: conducting the NYSE Euronext board of directors' annual governance review;
•: reviewing and recommending the governance guidelines for NYSE Euronext;
•: establishing an appropriate process for, and overseeing implementation of, the NYSE Euronext board of directors' self-assessments (including board self-assessment, committee self-assessments and director assessments);
•: recommending the compensation of NYSE Euronext directors;
•: conducting succession planning for the chief executive officer and deputy chief executive officer of NYSE Euronext;
•: removing directors of the Dutch Foundation and the Delaware Trust for cause; and
•: appointing directors of the Dutch Foundation and the Delaware Trust after the initial directors, who will be jointly selected by Euronext and NYSE Group.

The nominating & governance committee will consider shareholder and public investor recommendations for candidates for the NYSE Euronext board of directors.

Management of NYSE Euronext

The management committee of NYSE Euronext will be comprised of up to 16 members, including an equal number of NYSE Group designees and Euronext designees. The only members of the senior management teams of NYSE Group and Euronext who will also serve as directors of NYSE Euronext are the chief executive officer of NYSE Group immediately prior to the combination and the chief executive

161

officer of Euronext immediately prior to the combination (See "Directors and Management of NYSE Euronext After the Combination").

Compensation of Directors and Executive Officers

NYSE Euronext has not yet paid any compensation to its directors, executive officers or other managers. The form and amount of the compensation to be paid to each of NYSE Euronext's directors, executive officers and other managers will be determined by the NYSE Euronext board of directors as soon as practicable prior to or following the successful completion of the combination. For historical compensation information about executive officers and directors of NYSE Group and Euronext see "Information About NYSE Group—Director Compensation and Indemnification" and "—Executive Compensation."

INDUSTRY

General

NYSE Group and Euronext operate exchange markets for equity securities, bonds and other fixed income securities, options and, in the case of Euronext, other derivative products. Each provides listing and market data services, NYSE Group also provides regulatory services, and Euronext also operates in the business of market-related software sales. Each is subject to competition within the industry, and to extensive governmental regulation. Although globalization and technology advances are providing increasing commonalities, there are differences in how U.S. and European markets operate and are regulated.

United States

Traditional Market Centers. The U.S. capital markets consist of several market centers that systematically bring together buyers and sellers for the purpose of buying and selling securities. Generally, market centers are typified by the type of security products listed for trading on the market. Historically, stock markets like the NYSE operated primarily on a trading floor with all trades in a particular stock taking place in a specific place on the floor through or under the supervision of a designated dealer known as a specialist. A specialist oversees trading and is required to maintain a fair and orderly market, acting as both a market maker and auctioneer.

In 1971, the National Association of Securities Dealers Automated Quotation system, or Nasdaq, an electronic quotation network without a physical trading floor, was introduced as an enhancement of the traditional telephone based over-the-counter market.

Electronic Trading. In 1996, the SEC adopted the order handling rules which allowed a number of electronic trading systems (including the Archipelago ECN, the precursor of NYSE Arca), to emerge and compete with traditional market centers. These electronic networks included ECNs and other alternative trading systems, which provide an efficient means of access to market centers. Innovations in technology and telecommunications have increased the speed of communications and the availability of information, facilitated the globalization of commerce, and lowered transaction costs. New methods enable investors to access and participate in the equity securities markets more easily and quickly and less expensively. These developments, combined with the implementation of the order handling rules, have led to significant growth in electronic trading. However, the impact of electronic trading has been varied with respect to NYSE-listed equity securities and Nasdaq-listed equity securities. Electronic trading has thus far had a more significant impact on the market structure of the Nasdaq market and today much of the volume in Nasdaq-listed securities is handled by electronic trading systems like NYSE Arca. However, electronic trading in NYSE-listed securities continues to grow on NYSE Direct+®, competing crossing systems and ECNs.

The U.S. securities markets are subject to extensive regulation by the SEC, as well as to regulation by SROs under the Exchange Act, including New York Stock Exchange, LLC and NYSE Arca, Inc.

Europe

Exchange trading in Europe has historically been highly fragmented. Each country operated its own exchange that was linked to a "closed" clearing system and central securities depositary ("CSD"). International users were therefore obliged to interface with multiple national systems. In global markets, where customers increasingly trade across national borders, time zones, and instruments, particularly following the introduction of the Euro, the fragmented nature of Europe's capital markets was increasingly viewed as anachronistic. Recent years have seen powerful and inter-related competitive pressures that have transformed (and continue to transform) Europe's capital markets. These include:

•: technological developments, including the introduction of new information and communication technologies that have made financial markets both more efficient and more easily accessible;

163

•: the near-universal migration to lower-cost, screen-based, electronic trading that has given additional impetus for consolidation as users look to exchanges to provide a wider range of cross-border services;
•: the continuing evolution of once purely national capital markets into a European capital market, and the consequent demand from issuing companies, brokers, and investors for pan-European trading facilities and liquidity pools that correspond to a European capital market;
•: the development and increasing use of alternative trading platforms and smart order routing technology;
•: strong demand from cost-sensitive users for lower trading costs and transaction fees, increased liquidity, and improved systems capability; and
•: regulatory initiatives intended to increase the scope in Europe for internalisation and trading through alternative trading platforms.

A series of EU Directives has been adopted in the financial field in an effort to: (1) assist the creation of a single EU market in financial services by removing obstacles to the pan-European provision of financial services; (2) ensure that European capital markets remain deep and liquid, serving both issuers and investors; (3) enhance the passport rights for investment firms, create an EU passport for issuers and harmonise EU rules on regulated markets in order to facilitate cross-border trading; and (4) establish a regulatory framework allowing for competition between the various execution venues (regulated markets, multilateral trading facilities and internalisation) in all EU Member States.

The creation of Euronext in 2000 responded to these pressures and to users' desire for greater integration in cross-border trading. Euronext's subsequent development has manifested and, to some extent, driven these market changes.

U.S. Markets

U.S. Equities Market

Trading Environment. Over the long term, the U.S. equities markets have experienced a steady growth in trading volumes, although growth has been interrupted, from time to time, by volume declines resulting from weak economic performance and related factors.

For example, from 1995 to 2000, the major U.S. equities market indices experienced substantial growth. The growth in equity trading volumes resulted from a number of factors, including strong economic conditions and new methods for investing. Technological innovation, including the increasing importance of electronic trading platforms and the resulting drop in transaction costs, has further stimulated trading activity. New technology also allowed development of high-volume electronic trading strategies, which have helped increase daily trading volumes.

This period of growth was followed by a period of severe decline and significant volatility in the prices of U.S. equity securities between 2000 and early 2003. The weak and uncertain economic climate, combined with corporate governance and accounting concerns, contributed to generally lower equity securities prices, decreased corporate activity, increased market volatility, and a generally more difficult business environment. In 2003, however, overall volume in U.S. equity markets increased slightly, and this trend continued in 2004 and 2005. Trading volumes in U.S. equity markets increased by 6.9% in 2004 compared to 2003, and total volumes increased another 5.9% in 2005 compared to 2004. Consolidated volumes in NYSE-listed securities increased 4.7% in 2004 compared to 2003, and 13.7% in 2005 compared to 2004. Nasdaq trading volume increased by 7.5% between 2003 and 2004, yet it declined by 0.2% in 2005 compared to 2004. Prices strengthened in 2003 and 2004, and the major U.S. equity market indices posted back-to-back yearly gains for the first time since 1999. However, in 2005, the Dow Jones Industrial Average decreased 0.6%, while the Nasdaq Composite Index gained 1.4%, the S&P 500 Stock Index added 3.0% and the NYSE Composite Index rose 7.0%. In the first six months of 2006, equity volumes at the NYSE

164

and Nasdaq were up 19.3% and 14.8% year-over-year, respectively. Future performance will depend on a number of factors including macroeconomic trends and stock market performance.

Trading in NYSE-Listed Securities. The market centers that execute and report trades in NYSE-listed securities through the Consolidated Tape Association Plan ("CTA Plan") include the NYSE, NYSE Arca, the AMEX, the Boston Stock Exchange, the Chicago Stock Exchange, the Chicago Board Options Exchange, the National Stock Exchange, Nasdaq (which at present reports executions in listed securities effected off of exchanges as well as activity on the Nasdaq Market Center, INET and Brut, LLC), the National Association of Securities Dealers, the Philadelphia Stock Exchange and through "internalization" or off-exchange trading by member organizations. These market centers, as well as ECNs and other market participants, have access to the Intermarket Trading System ("ITS"), enabling them to route trading interest (through ITS) to publicly displayed quotes in all ITS participant markets trading U.S. exchange-listed stocks.

The NYSE, like other floor-based exchanges, is an auction-driven marketplace and trading is conducted in a single physical location with a single specialist in each stock and floor brokers executing customer orders in a continuous market. The specialist is required to maintain a fair and orderly market, acting as a full-time liquidity provider and dampening price volatility by using capital subject to stabilization rules to buy or sell against the prevailing trend. In contrast, NYSE Arca and other electronic market centers do not maintain a physical trading floor, and instead link traders to multiple U.S. market centers electronically. However, certain of these electronic market centers, such as NYSE Arca, also employ an auction-driven order execution structure.

Floor-based exchanges are, to varying degrees, integrating electronic trading into their floor-based models. Approximately 16.6% of the NYSE's total trading volume for the three-month period ended June 30, 2006 was executed electronically on NYSE Direct+®, NYSE's electronic trading platform. Electronic trading on the NYSE is expected to increase with the implementation of the NYSE Hybrid Market, which is intended to combine the best features of auction markets and electronic markets. The NYSE Hybrid Market is intended to provide investors greater access, faster executions and more trading choices through greater use of technology, while enhancing the benefits provided by specialists and floor brokers. For a more detailed discussion of the NYSE Hybrid Market, see "Information About NYSE Group—NYSE and NYSE Arca—The NYSE Hybrid Market^SM Initiative."

Trading in NYSE Arca-Listed Securities. Securities listed on NYSE Arca are considered "CTA Plan"-eligible securities. As a result, all market centers listed above are also able to report trades in NYSE Arca securities and use the ITS trading facility.

In May 2006, NYSE Arca implemented an enhanced market structure for trading in its listed securities. This platform is designed to unite the "best execution" benefits offered by traditional floor-based models with the speed benefits offered by electronic models. In particular, NYSE Arca-listed companies can be assigned a single Lead Market Maker ("LMM"), who has responsibilities to maintain a tight and two sided quote. Maintaining a narrow quote in an assigned stock is a similar obligation to that of a specialist. An LMM serves as a capital provider when there are no other competitive orders in the market, thus helping ensure investor orders obtain high quality executions. The liquidity (or capital) provided by LMMs is fully integrated with the electronic price-time priority model, which has been the mainstay of NYSE Arca since inception.

Trading in Nasdaq-Listed Securities. The market centers that execute and report trades in Nasdaq-listed securities through the Nasdaq OTC/UTP Plan include the Nasdaq, NYSE Arca, AMEX, the Chicago Stock Exchange, the Boston Stock Exchange, the National Stock Exchange, the Philadelphia Stock Exchange and the NASD's Alternative Display Facility (which is a quoting and trading facility only). The unlisted trading privilege ("UTP"), is a right, provided by the Exchange Act, which permits securities listed on any national securities exchange to be traded by other such exchanges. The NYSE is not a participant in

165

the OTC/UTP Plan and, as such, does not provide access for trading Nasdaq-listed securities; however, access is available through NYSE Arca.

Trading in Nasdaq-listed securities is conducted among a group of electronic and floor-based markets. Nasdaq also uses a decentralized multiple market maker model where market makers can internalize order flow (or fill an order with the market maker's own inventory). A number of electronic trading systems emerged during the mid-1990s as regulatory changes and technology advances paved the way for ECNs, including the Archipelago ECN, the predecessor to ArcaEx, to compete with Nasdaq. The technology capabilities of ECNs provided benefits including fast automated execution, certainty, anonymity and low-cost trading. Greater connectivity and smart order routing allowed for order flow to migrate more freely across competing market venues. In addition, growing volumes in the most liquid Nasdaq stocks enabled more trades to match on electronic agency systems without dealer intervention. These developments led to dramatic growth in electronic trading and resulted in a shift in liquidity away from Nasdaq toward ECNs, particularly in the most actively traded Nasdaq-listed stocks. Intense competition for order flow among participants led to significant pricing pressure, including lower transaction fees and the introduction of "liquidity payments" to customers who added system liquidity by posting buy orders or sell orders.

The key factor in the growth of competition in Nasdaq-listed securities was the SEC's adoption of the order handling rules in 1996. These rules provide a specified role for qualified ECNs. The order handling rules deal specifically with the processing of limit orders, which are orders with an associated limit price above which a buyer, or below which a seller, will not trade. Under the order handling rules, a market maker that receives a limit order better than its own published quote, or at the same price as its published quote for more than a de minimis size, must generally execute the order, incorporate the limit order price into its published quote or pass the order on to an ECN for public display and execution access. The rules created opportunities for the development of qualified ECNs, including the Archipelago ECN, to which Nasdaq market makers could route certain customer limit orders in order to comply with the new rules. For this reason, and due to the other benefits of an electronic platform, such as faster execution and anonymity, qualified ECNs began to evolve as alternative trading venues for trade execution.

Regulation and Regulatory Services. The United States securities markets are subject to extensive regulation by the SEC, as well as to regulation by Self-Regulatory Organizations under the Securities Exchange Act of 1934, as amended, including New York Stock Exchange, LLC and NYSE Arca, Inc. See "Regulation—U.S. Regulation."

Listing Services. The global listing services industry is described below under "Industry—Global Listing Services."

Market Data Services. Registered national securities exchanges in the United States participate in the collection, consolidation and dissemination of trade and quote data and earn revenue generated from the sale of such data. These fees are referred to as "tape fees." No such apparatus for the collective dissemination of market data exists in Europe, with individual exchanges instead distributing proprietary market information.

In the United States, market data fees are distributed among participants pursuant to the terms of the various national market system plans—the CTA Plan and CQ Plan in NYSE and AMEX-listed securities, and the Nasdaq OTC/UTP Plan in Nasdaq-listed stocks. Participation in the three consolidated tape plans is mandatory to receive market data fees and U.S. regulations determine how the revenues are divided among the exchanges and how much revenue can be shared by exchanges with ECNs and broker/dealers. Under the CTA Plan and CQ Plan, after costs are deducted, market data fees are distributed among participants based on their respective number of trades. Under the OTC/UTP Plan in Nasdaq-listed stocks, after costs are deducted, market data fees are distributed among participants based on their respective number of shares and trades. The NYSE participates only in the CTA Plan and CQ Plan, and is currently not a UTP Plan participant. NYSE Arca, Inc. is a member of the CTA Plan and CQ Plan, and the Nasdaq OTC/UTP Plan and shares in the revenue generated from each of these plans.

166

Regulation NMS will update the formulas for allocating revenue derived from market data fees by, among other things, including a component that reflects quoting activity and eliminating allocations for manual quotes. Regulation NMS also requires the creation of advisory committees composed of non-SRO representatives to the data plans, and authorizes market centers to distribute their own trade data independently of the data plans.

In addition to sharing revenue generated by the sale of consolidated market data under the data plans, these participants sell other proprietary data to vendors and market participants. Certain exchanges also have established programs to share the market data revenue they receive with market participants that report trades to them in AMEX-listed and Nasdaq-listed securities to compete for order flow.

U.S. Equity Options Markets

The market for trading U.S. equity options has increased dramatically over the past 10 years at a compound annual growth rate of 22.9% from 1995 to 2005, with average daily contract volumes increasing 26.3% in 2005, and 35% year-over-year growth in the first six months of 2006, according to the Options Clearing Corporation. Various factors have contributed to the growth in options trading volumes including increasing investor awareness and broader participation, rising electronic trading and technology deployment, tighter spreads and lower transaction fees, and deeper liquidity. In recent years, trading options has become faster, cheaper, more transparent and more efficient.

There are currently six U.S. equity options exchanges competing for order flow (or orders committed to a particular market) in many of the same equity options products. The original four traditional floor-based options exchanges include AMEX, the Chicago Board Options Exchange, NYSE Arca, Inc. and the Philadelphia Stock Exchange. In January 2005, Archipelago entered into an agreement to acquire the parent company of the Pacific Exchange. The other two U.S. equity options exchanges are the International Securities Exchange and the Boston Options Exchange, which are fully electronic exchanges. As of April 2006, Nasdaq allows customers to route options orders to major option exchanges. In addition, Nasdaq recently announced its intention to provide for option order matching, pending SEC approval that is expected in late 2007.

All of the traditional floor-based option exchanges have adopted hybrid models, incorporating greater electronic trading capabilities to complement floor trading and improve access for customers, broker/dealers and market makers. For example, in October 2003, NYSE Arca, Inc. introduced its PCX+ electronic platform to accommodate independent quotes from market makers, and, on August 7, 2006, NYSE Arca began replacing PCX+ with a new trading platform that offers greater execution speed, reliability, capacity, and functionality, including functionality for trading options in penny increments.

The SEC regulates the options industry. It is a requirement under the Options Intermarket Linkage Plan and SRO rules that options exchanges avoid executing trades at prices inferior to the best available price, called a "trade through." In early 2003, options exchanges began sending orders through an intermarket linkage that is governed by the Options Intermarket Linkage Plan and is designed to facilitate the routing of orders between exchanges and improve execution quality.

Greater competition among equity options markets since 1999 has resulted in a proliferation of incentive arrangements, including payment for order flow. NYSE Arca, Inc. announced plans to initiate a pilot program to begin quoting and trading listed options in certain ETFs in penny increments, instead of five or ten cent increments. Recently, the SEC proposed a penny pilot in a limited number of issues for implementation in January 2007. The move to penny pricing could have a significant impact on the competitive environment as orders are directed to the markets with the most aggressive quotes. The change may also add significant quote traffic and require substantial additional bandwidth capacity. The impact of penny pricing in options has been the subject of significant debate, and this proposal may not be approved by the SEC in the near future. For further discussion of the potential effect of the SEC rejecting this proposal.

U.S. Fixed Income Markets

In contrast to the equity and options markets, the fixed income markets are more fragmented and opaque. Fixed income markets have traded over-the-counter with institutional investors and broker dealers executing transactions via telephone and fixed income securities changing hands through intermediaries known as inter-dealer brokers (or IDBs). Electronic fixed income securities trading systems have emerged and are creating more centralization, improving transparency and increasing the speed of execution. These systems operate as quasi exchanges defined by centralization of orders, more open market information and more standardized rules. Currently, much of the electronic trading in fixed income securities occurs in the highly liquid U.S. Treasuries market. Voice brokering remains more prominent in other fixed income securities markets, such as corporate and municipal bonds.

The NYSE was an early pioneer in providing electronic fixed income trading through the Automated Bond System® (ABS®), which was initially implemented in 1977. Most ABS® volume is in odd-lot corporate bonds, but the system also offers trading in convertible, government and municipal bond trading. ABS® is an order-driven system that allows broker-dealers to trade directly with each other on an electronic basis, with real-time reporting of all quotations, trade prices, and quantities. These broker-dealer clients represent the principal source of secondary market liquidity in sovereign and corporate bonds.

Key competitors to ABS® include inter-dealer brokers that conduct business over the telephone and electronically, other multi-dealer trading companies and electronic trading venues such as MarketAxess and BondDesk. The requirement that bonds must list on the NYSE in order to be traded on the NYSE's ABS® system has limited ABS® growth in recent years, with the total value traded on ABS® at $299 million through June 30, 2006, $956 million in 2005, compared to $1.3 billion in 2004 and $2.5 billion in 2003.

On July 8, 2005, the SEC published for comment a proposed rule change that, if approved, would allow the NYSE to trade a substantially greater number of corporate bonds on ABS® since bonds would not be required to be listed in order to be traded. If approved, most of the corporate bonds issued by NYSE-listed equity issuers and their wholly owned subsidiaries would be eligible for trading on the NYSE's ABS® system. The comment period ended on August 15, 2005 and the NYSE is awaiting further action from the SEC on the proposal. In the meantime, NYSE Arca developed a new fixed income platform which will replace the current ABS® technology. This platform offers greater execution speed, capacity, functionality and reliability. The NYSE has filed rules with the SEC relating to this platform that must be approved prior to its rollout.

European Markets

European Equities Markets

In 2005, trading volumes on the major European stock exchanges increased significantly against the previous year and most of the leading share indices closed substantially up for the year. Also, the continued rise in hedge fund and electronic trading strategies has been a contributing factor to the growth in electronic order book trading. According to the Federation of European Securities Exchanges (FESE), the year-over-year trading volume on the London Stock Exchange was up 24%, Deutsche Börse was up 20% and Euronext was up 15% in 2005. During the first six months of 2006, year-over-year trading volume growth was up 52% on Euronext, 48% on Deutsche Börse, and 46% on the London Stock Exchange.

Trading in Euronext-Listed Securities. Euronext is Europe's largest cash equities market based on average daily trades and average daily turnover in its electronic order book. During 2005 and the first half of 2006, on an average day, over 613,113 and 894,622 trades, respectively, valued at €7.1 billion and €10.2 billion, respectively, were executed on Euronext. Belgian, Dutch, French, and Portuguese equities are traded on Euronext, with transactions being carried out on the NSC (nouveau système de cotation) system, a cross-border electronic trading platform operated by Euronext. Euronext-listed equities are traded predominantly on Euronext exchanges, with only very low volumes of Dutch equities traded on other

168

European exchanges. The limited incidence of on-exchange competition in respect of the same equity results from the economics of cash trading, which is characterized by network externalities: the greater the number of users trading a security or group of securities on a given exchange, the more companies will be attracted to issue securities on that exchange and, accordingly, the more traders will use that exchange, this cumulative process creating the highest possible levels of liquidity. Liquidity, characterized frequently as the ability to buy or sell an equity immediately without materially affecting the market price, is a key to attracting and retaining customers. As a function of liquidity, trading in individual equities in Europe almost invariably concentrates and remains on a single exchange, and European exchanges therefore tend to have strong market positions and maintain much of the local trading in national markets. As such, on-exchange cash trading in U.K. equities is concentrated on the London Stock Exchange, and similarly trading in German equities is transacted on Deutsche Börse, while trading in Belgian, Dutch, French, and Portuguese equities is carried out exclusively or predominantly on Euronext.

Cash trading on Euronext's markets in Paris, Amsterdam, Brussels and Lisbon takes place via the NSC system, Euronext's common electronic trading platform for the cash market. The NSC system was originally the trading platform for Euronext Paris; Euronext Brussels and Amsterdam migrated to NSC in 2001 and Euronext Lisbon migrated in 2003. The NSC system is a fully automated electronic trading platform that allows trading members either to route their clients' orders electronically or to enter orders manually into computer workstations installed on their premises and linked to the NSC system. The NSC system maintains a central order book for every traded security, in which it matches buy and sell orders electronically. After a trade has been executed, trade confirmations are sent electronically in real time to the trading members. Trading on all of the principal European exchanges is transacted predominantly via automated electronic systems, as opposed to on the trading floor. Electronic trading systems were adopted by European exchanges in the 1990s, with the migration of trading activity to electronic order books facilitating the adoption of more sophisticated trading techniques by customers, including, for instance, the development of statistical arbitrage trading strategies.

European Derivatives Markets

The major derivatives exchanges in Europe include Eurex, which is a part of Deutsche Börse, Euronext.liffe, Borsa Italiana, MEFF and OMX. Euronext.liffe itself covers five markets: Belgium, France, the Netherlands, Portugal and the United Kingdom. Following the integration of these separate markets, Euronext.liffe makes available all its products via one trading platform—LIFFE CONNECT®—which is accessed by members from over 30 countries.

Derivatives exchanges face significant global competition from the OTC market. The Bank of International Settlements has estimated that derivatives traded OTC had a notional outstanding value of approximately US$284 trillion in 2005, representing 83% of the total notional value of all derivatives contracts traded worldwide over the same period.

Derivatives may be divided into two broad categories: futures and options. Having regard to the underlying instruments to which derivatives relate, these two broad categories can be segmented further into the following product areas:

•: short-term interest rates;
•: medium- to long-term interest rates;
•: individual equities;
•: equity indices;
•: currencies; and
•: commodities.

While the major derivatives exchanges trade a diverse portfolio of products, the core businesses of many exchanges relate to particular product areas. For example, Euronext.liffe offers a range of short-term

169

interest rate products, including Short Sterling and its flagship Euribor contracts. It also offers for trading a suite of national and pan-European equity indices, and has an active individual equity derivatives business, particularly in the U.K. and Dutch markets. Eurex has deep liquidity pools in its benchmark long-term euro interest rate derivatives (based on the Bund, Bobl and Schatz), its pan-European indices, such as the Dow Jones EuroStoxx 50 index, and individual equity options.

The European equity derivatives market is made up of listed and OTC products. Typically, the OTC market is two to three times the size of the listed market. The primary derivative products are futures and options on individual securities and futures and options on indices, both domestic and cross-border indices. Most domestic exchanges provide futures and options on their local (national) index and the main component securities of those indices. Derivatives on other cross-border indices, including the FTSEurofirst 80 and 100 indices, have evolved since the formation of the euro. Listed and OTC trading is predominantly in plain-vanilla products, with additional structured and exotic products trading OTC. Listed markets are characterized by central order books in the main derivative classes, supported by wholesale trading mechanisms such as block trading or clearing facilities. For example, Euronext.liffe has developed Bclear, which combines the benefits of the OTC market (e.g. flexibility) with those of an exchange and clearing house (e.g. reduced counterparty credit risk). Bclear offers over 350 equity futures and options from 16 countries of which over 240 have traded since Bclear launched in October 2005. Bclear complements Euronext.liffe's central markets, providing investors with a choice of trading venues.

The substantial growth in derivatives trading volume over the past five years is attributable to a number of factors, including cyclical and secular factors. Cyclical factors contributing to growth include the uncertainty around future interest rate movements and greater price volatility prompting hedging activity. Favorable secular factors include the growth in electronic trading and expanded distribution, product innovation, growing customer sophistication and the proliferation of new asset class funds. An increasingly sophisticated investment community of financial institutions, hedge funds and proprietary trading firms are committing significant amounts of capital to trading in derivatives and increasing the need for risk management tools using derivatives. Additionally, while the derivatives markets remain largely traded OTC, the increasing focus on improving transparency and more effective management of counter-party risks is driving growth. Future growth will depend on macroeconomic trends, the performance of underlying instruments and other factors as noted above.

Global Listing Services

Regulated national securities exchanges and markets affiliated with national securities associations provide primary and secondary listing services to companies that are seeking to have their securities admitted to trading. Listing is a necessary pre-condition to the trading of securities on an exchange. By listing its securities, an issuing company can raise capital from investors both at the time of initial listing and at the time of any additional offering.

Issuing companies may list their securities on multiple exchanges. A company's main listing is referred to as its "primary listing" while subsequent listings on other exchanges are referred to as "secondary listings." The vast majority of issuing companies obtain only a primary listing, invariably on a domestic exchange.

The primary U.S. markets on which companies may list their securities are the NYSE, NYSE Arca, Nasdaq Stock Market, and AMEX, as well as the regional exchanges. The NYSE has the highest overall listing standards of any securities marketplace. During the three months ended June 30, 2006, the NYSE obtained approximately 89.7% of all domestic initial public offerings that qualified to list under the NYSE's standards, as measured by the aggregate proceeds raised by companies listing on U.S. exchanges. Building on the NYSE's premier brand and listing business, NYSE Arca provides a listings venue for smaller-cap firms that do not initially qualify for the NYSE's listing standards. We estimate that approximately two-thirds of the companies that currently list on Nasdaq Global Market do not meet the

170

NYSE's listing requirements. NYSE Arca provides us with an opportunity to target a select universe of these companies.

In Europe, issuing companies generally obtain primary listings on their relevant national exchange. With a presence in five European countries, and given its cross-border integrated exchange model, Euronext is uniquely positioned to provide a natural gateway to the eurozone, granting issuers access to a broad European investor base. To further improve ease of access to the European capital pool, Euronext comprehensively reformed its listing activities in 2005. A single list, Eurolist by Euronext, was created, encompassing all of Euronext's regulated national markets. Issuers continue to choose an initial entry point (Paris, Amsterdam, Brussels or Lisbon) for the listing of their securities, which has important regulatory consequences, but once admitted these securities are then accessible from all Euronext markets through Eurolist. In May 2005, Euronext Paris also launched Alternext, an innovative market designed to assist small-to-medium sized enterprises raise capital through the listing of their securities. This was followed by the announcement of approval of Alternext Amsterdam on May 30, 2006 and the launch of Alternext Brussels in June 2006. Other continental European exchanges also provide access to the eurozone capital pool, including Bolsa Madrid, Borsa Italiana, Deutsche Börse, the Irish Stock Exchange, and the Luxembourg Stock Exchange.

Exchanges in the United States, in Europe, and Australasia, notably the Hong Kong, Tokyo and Australian stock exchanges, provide secondary listing services to non-domestic issuing companies, and primary listing services to those companies that do not have access to a well-developed domestic exchange. Companies adopt secondary listings as complements to their primary listings, providing access to the distinct investor bases and capital pools available in differing geographic regions.

European Market Data Services

In Europe, consolidated market data does not exist. European exchanges instead individually distribute proprietary market information, including real-time pricing data and trading volume data, and non-proprietary market data, such as indices and historical information, which is available also from third-party data vendors.

European Fixed Income Markets

As is the case in the United States, the European trading of fixed income securities is conducted almost exclusively on the OTC markets, whether via direct bilateral trading between counterparties, through the use of intermediation services provided by inter-dealer brokers, or through proprietary trading platforms operated by banks. MTS is Europe's leading platform for fixed income products. MTS is majority owned by MBE Holding, a joint venture between Euronext and Borsa Italiana. It is authorized to conduct such activities by Italy's Ministry of Finance, and is regulated by the Bank of Italy and the Commissione Nazionale per le Societá e la Borsa(CONSOB). Since the adoption of the Euro in 1999, Euro-denominated issues have become more attractive for both investors and issuers. MTS plays a key role in promoting the ongoing development and integration of the European government bond market. It covers the national debt markets of every eurozone member as well as government bond markets of other countries, including Poland and Turkey. MTS's key competitors are inter-dealer brokers, such as ICAP plc and Cantor Fitzgerald & Co (which, through eSpeed Inc., operates the world's largest market for government bonds).

Market Trends and Developments

Globalization, consolidation, regulation, and advances in technology are changing the way global exchange markets operate.

171

Globalization

One of the most significant industry developments in recent years is the accelerating pace of globalization of the world markets. The emphasis on greater geographic diversification of investments, investment opportunities in the fast growing markets like China and India as well as expanded cross-border commercial activities are leading to increasing levels of cross-border trading and capital movements. Financial institutions, investment firms and other financial intermediaries increasingly trade across national boundaries, in numerous markets and asset classes, outside traditional exchanges and even directly among themselves. This has led to increased competition in listings and trading between domestic and international exchanges, and to a demand for increased technological and regulatory cooperation between market centers in different jurisdictions. And, in response to these trends, exchanges are both expanding access to their markets across borders and consolidating.

Demutualization and Consolidation

Another common trend in the industry is demutualization and consolidation of market centers. In recent years, many market centers in both Europe and the United States have demutualized to provide greater flexibility for future growth. In addition, the number of new market entrants, the need to respond to the globalization of capital markets, and the desire to provide cross-border services to clients has led to a series of consolidations, both in the United States and abroad. For example, in 2000, the exchanges of Paris, Brussels and Amsterdam combined to create Euronext N.V., the first cross-border European exchange. In 2002, Euronext acquired LIFFE (the London International Financial Futures and Options Exchange) and merged with BVLP (Bolsa de Valores de Lisboa e Porto), a Portuguese exchange. In 2001, the Frankfurt Stock Exchange and the London Stock Exchange conducted their initial public offerings and, in 2006, the Madrid Stock Exchange (Bolsa de Madrid) continued the trend, becoming a listed public company. While some non-U.S. exchanges have been combining across equity and derivatives markets and moving to a multi-product business model to broaden their revenue sources, the major U.S. stock and derivatives markets remain largely separate, though customers are increasingly seeking multi-asset class execution products. We believe deregulation and competition will continue to pressure exchanges to consolidate across products and geographies to diversify revenues and gain operating efficiencies necessary to compete for customers and intermediaries.

In recent years, there have been a number of strategic alliances and consolidations among stock market participants, including Archipelago's merger with REDIBook ECN LLC and acquisition of PCX Holdings, Nasdaq's acquisition of both INET and Brut, LLC, and the merger of the NYSE and Archipelago.

In addition, there has been a recent trend in the United States to invest in or create securities market centers and ECNs such as:

•: On April 19, 2006, the International Securities Exchange announced that it is entering the cash equities market through the launch of the ISE Stock Exchange, L.L.C., in conjunction with several strategic partners including Bear Stearns, Citadel Derivatives Group, Deutsche Bank, Interactive Brokers Group, JPMorgan, Knight Capital Group, and Sun Trading. On July 24, 2006, the ISE Stock Exchange announced that Nomura Securities, Van der Moolen, and E-Trade Financial had also joined the ISE Stock Exchange as strategic partners. ISE Stock Exchange launched its first product during the third quarter of 2006.
•: In January 2006, the SEC approved Nasdaq's application to operate as a national securities exchange, allowing it to separate from its longtime regulator and owner, the NASD. Nasdaq now operates a new subsidiary, the Nasdaq, as an SRO. Operating as an exchange means the Nasdaq functions according to its own trading, listing, membership and other rules, with its own members and its own regulations.

172

•: On September 6, 2006, the National Stock Exchange announced the sale of a majority stake to a group of strategic investors including Bear Stearns, Citigroup, Credit Suisse, Merrill Lynch, Bloomberg Tradebook, and Knight Capital.

Regulatory Change

Regulation NMS in the United States and the MiFID in Europe are two major sets of regulation that are expected to have a substantial impact on U.S. equity trading and European cash and derivatives trading, respectively. While there are fundamental differences in these two pieces of legislation, both attempt to create fairer markets that better protect investors while facilitating competition between market participants. These regulations create new opportunities and challenges for existing exchanges. See "Regulation" and "Risk Factors."

Technology Advancements

Innovations in technology and telecommunications have increased the speed of communications and the availability of information, facilitated the globalization of commerce, and lowered transaction costs. Advanced trading technology have enabled investors to access and participate in the securities and derivatives markets more easily and quickly and less expensively.

In the United States, advances in technology, as well as the order handling rules of 1996, led to the rapid emergence of electronic trading systems (including the Archipelago ECN, the precursor of ArcaEx), which competed with traditional U.S. market centers. Electronic trading has thus far had a more significant impact on the market structure of the Nasdaq market and today much of the volume in Nasdaq-listed securities is handled by electronic trading systems like ArcaEx. In NYSE-listed securities, a significant portion of trading still occurs on a trading floor, but electronic trading continues to grow on NYSE Direct+®, competing exchanges, crossing systems and ECNs.

Floor-based exchanges are, to varying degrees, integrating electronic trading into their floor-based models. Approximately 16.6% of the NYSE's total trading volume for the three month period ended June 30, 2006 was executed electronically on NYSE Direct+®, NYSE's electronic trading platform. Electronic trading on the NYSE is expected to increase with the implementation of the NYSE Hybrid Market^SM, which is intended to combine the best features of auction markets and electronic markets. The NYSE Hybrid Market^SM is intended to provide investors greater access, faster executions and more trading choices through greater use of technology, while enhancing the benefits provided by specialists and floor brokers. For a more detailed discussion of the NYSE Hybrid Market^SM , see "Information About NYSE Group—The NYSE and NYSE Arca—The NYSE Hybrid Market^SMInitiative."

In Europe, the major markets are largely electronic, order-driven markets. In the U.K. market, much of the volume is traded on the London Stock Exchange's SETS system. In Germany, Deutsche Börse operates the Xetra system in cash trading and there is some floor-based trading in Frankfurt, but it is limited. Also, Deutsche Börse operates the electronic Eurex platform for derivatives trading. Euronext licenses two state-of-the-art trading platforms—NSC and LIFFE CONNECT®—from Atos Euronext Market Solutions. NSC is a cash market trading system originally developed by Euronext Paris that is now used by more than 15 exchanges on four continents, including Euronext's single cash trading platform for the markets of Amsterdam, Brussels, Lisbon, and Paris. LIFFE CONNECT® is an electronic trading platform for derivatives that is used by Euronext.liffe in Amsterdam, Brussels, Lisbon, London and Paris, the Chicago Board of Trade, the Kansas City Board of Trade (KCBT), Minneapolis Grain Exchange (MGEX), Winnipeg Commodity Exchange (WCE) and Tokyo Financial Exchange (TFX).

REGULATION

U.S. Regulation

Overview

U.S. federal securities laws have established a two-tiered system for the regulation of securities markets and market participants. The first tier consists of the SEC, which has primary responsibility for enforcing federal securities laws and regulations and is subject to Congressional oversight. The second tier consists of the regulatory responsibilities of self-regulatory organizations, or SROs, over their members. SROs are non-governmental entities that are registered with, and regulated by, the SEC.

Securities industry SROs are an essential component of the regulatory scheme of the Exchange Act for providing fair and orderly markets and protecting investors. To be a registered national securities exchange, an exchange must be able to carry out, and comply with, the purposes of the Exchange Act and the rules and regulations under the Exchange Act. In addition, as an SRO, an exchange must be able to enforce compliance by its members, and individuals associated with its members, with the provisions of the Exchange Act, the rules and regulations under the Exchange Act and its own rules.

Broker-dealers must also register with the SEC, and member organizations must register with an SRO, submit to federal and SRO regulation, and perform various compliance and reporting functions.

Two subsidiaries of NYSE Group, NYSE and NYSE Arca, Inc., as national securities exchanges and SROs, are registered with, and subject to oversight by, the SEC. Accordingly, the NYSE and NYSE Arca, Inc. are regulated by the SEC and, in turn, are the regulators of their member organizations. The regulatory functions of both the NYSE and NYSE Arca, Inc. are performed by NYSE Regulation. For a discussion of the responsibilities and structure of NYSE Regulation see "Information About NYSE Group—NYSE Regulation."

SEC Oversight

The trading of securities in the United States is subject to vigorous regulation by the SEC, which oversees the regulatory functions of all registered securities exchanges and associations. It conducts on-site inspections through the Office of Compliance Inspections and Examinations on a regular basis and evaluates the effectiveness of regulatory programs, making recommendations for improvements and enhancements. In particular, the SEC has broad-ranging oversight authority over the regulatory programs of the NYSE and NYSE Arca, Inc. with respect to examination of member organizations, market surveillance, enforcement and compliance with listing standards. Each of the NYSE and NYSE Arca, Inc., as SROs, is potentially subject to regulatory or legal action by the SEC at any time. The SEC has broad enforcement powers, including the power to censure, fine, issue cease-and-desist orders, prohibit NYSE Euronext's exchanges from engaging in some of their businesses or suspend or revoke their designation as registered national securities exchanges. Actions by the SEC can therefore result in the imposition of additional obligations on the NYSE and NYSE Arca, Inc. to expend additional money on regulatory resources and technology.

The NYSE and NYSE Arca are subject to the record keeping requirements of Section 17 of the Exchange Act, including the requirement pursuant to Section 17(b) of the Exchange Act to make available their records to the SEC for examination.

Section 19 of the Exchange Act provides that the NYSE and NYSE Arca must generally submit to the SEC for approval proposed changes to their respective rules, practices and procedures. The SEC will typically publish the proposal for public comment, following which the SEC may approve or disapprove the proposal, as it deems appropriate. The SEC's action is designed to ensure that the SRO's rules and procedures are consistent with the Exchange Act and the rules and regulations under the Exchange Act.

174

Although NYSE Euronext will not be a registered SRO, it will be, just as NYSE Group currently is, the parent company of two SROs. As such, certain aspects of the certificate of incorporation, bylaws and structure of NYSE Euronext and its subsidiaries will be (just as certain aspects of the certificate of incorporation, bylaws and structure of NYSE Group and its subsidiaries currently are) subject to SEC oversight, including certain ownership and voting restrictions on its stockholders. See "Description of Capital Stock—Ownership and Voting Limits on NYSE Euronext Capital Stock" for a description of certain of these restrictions.

SRO Regulation of Member Organizations

In general, SROs are responsible for regulating their members through the adoption and enforcement of rules governing the business conduct and financial responsibility of their members. Each SRO must:

•: carry out and comply with the purposes of the Exchange Act and the rules and regulations of the Exchange Act; and
•: enforce compliance by its member organizations and individuals associated with its members, with the provisions of the Exchange Act, the rules and regulations of the Exchange Act and the rules of the exchange.

In this capacity, each SRO, such as the NYSE or NYSE Arca, Inc., acts as a regulator of its member organizations and must carry out certain regulatory activities, including:

•: establishing rules for the operation of the exchange;
•: inspecting its member organizations;
•: regulating market activity; and
•: adopting and enforcing rules governing the business conduct and financial responsibilities of its member organizations.

The rules of the exchange must also assure fair representation of its member organizations in the selection of its directors and administration of its affairs, and, among other things, provide that one or more directors be representative of issuers and investors and not be associated with a member of the exchange or with a broker or dealer. Additionally, the rules of the exchange must be adequate to ensure fair dealing and to protect investors, and may not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Exchange Act. While these requirements are generally intended to safeguard the integrity of securities markets and the interests of public market participants, they do not specifically take into account or otherwise specifically protect the interests of NYSE Euronext stockholders, as such.

Recent U.S. Regulatory Developments

In November 2004, the SEC published for comment proposed rules, known as "Regulation SRO," that would require SROs, such as the NYSE and NYSE Arca, Inc., to implement certain corporate governance, transparency, oversight and ownership rules. If adopted, the rules would require, among other things, each SRO to submit to the SEC for approval its new or amended rules no later than four months following the date of publication of the final SEC rules in the Federal Register, and the SRO's rules would be effective no later than one year after this publication and approval. The SEC also published a concept release regarding the efficacy of self-regulation by SROs. The comment period on the proposals and concept release ended in March 2005.

In addition, on April 6, 2005, the SEC adopted Regulation NMS, which will alter in significant respects the regulatory environment governing the securities industry.

175

More information on the recent regulatory developments described below, including the full text of any documents published by the SEC, may be obtained from the SEC's website at the following address: http://www.sec.gov.

SEC Proposals Relating to Governance, Transparency, Oversight and Ownership. The SEC's proposed rules, in "Regulation SRO," included requirements relating to the structure and procedures of SROs, including proposals concerning:

•: the independence of directors;
•: the representation of members, issuers and investors on the board of directors and standing committees of the board of directors;
•: the effective separation of regulatory and business functions;
•: the establishment of procedures to prevent use of regulatory information for non-regulatory purposes; and
•: periodic public disclosure and reporting.

NYSE Euronext does not know whether, or in what form, any of these proposals will be adopted. NYSE Euronext has organized its corporate governance structure and ownership rules in substantial compliance with the proposed rules. However, any changes in the proposed rules or the adoption of a final Regulation SRO may result in changes to the manner in which it conducts its business and governs itself. The new reporting rules also could, among other things, make it more difficult or more costly for NYSE Euronext to conduct its existing businesses or enter into new businesses. All SROs will be required to comply with any rules adopted as a result of the SEC's proposals.

SEC Concept Release. Simultaneously with the proposals described above, the SEC published a concept release exploring the efficacy of self-regulation by SROs. The SEC noted that, while competition in the U.S. securities industry has resulted in innovation in trading, lower trading costs and increased responsiveness to customers, it has also placed greater strain on the self-regulatory system and increased the perceived or actual conflicts inherent in the SRO model between the regulation of members and the realization of profits. The concept release discusses the inherent conflicts of interest between SRO regulatory operations, and members, market operations, issuers and stockholders, the costs and inefficiencies of multiple SROs arising from multiple and sometimes overlapping rules, inspection regimes and staff, the challenges of surveillance of cross market trading by multiple SROs, the funding SROs have available for regulatory operations and the manner in which SROs allocate revenue to regulatory operations. It also analyzes a number of alternative regulatory approaches.

Responses to SEC Proposals. The NYSE filed two comment letters with respect to the rule proposals and concept release and Archipelago (a predecessor to NYSE Arca) filed one comment letter jointly with other securities exchanges. Some of the proposals discussed in the concept release for reallocating regulatory responsibility could reduce the NYSE's self-regulatory authority and have a significant impact on NYSE Euronext, its business and operating results, and the efficacy of the regulation of its member organizations.

Regulation NMS. On April 6, 2005, the SEC adopted Regulation NMS, which is expected to significantly alter the regulatory environment governing the securities industry. The provisions of Regulation NMS are described below and include the Order Protection Rule, Access Rule, Market Data Rule and Sub-Penny Rule.

In a subsequent release, the SEC provided for extended compliance dates for each provision of Regulation NMS, specifically: (1) compliance with the Access Rule and Order Protection Rule is required by February 15, 2007; (2) compliance with the so-called "sub-penny" rule was required by January 31, 2006; and (3) compliance with the Market Data Rule was extended to April 1, 2007.

176

Order Protection Rule. The Order Protection Rule modernizes "trade-through" protections, which previously applied only to Amex and NYSE exchange-listed securities. It requires trading centers to establish, maintain, and enforce written policies and procedures that are reasonably designed to prevent trade-throughs on that trading center of protected quotations and, if relying on exceptions to the Order Protection Rule, that are reasonably designated to assure compliance with the terms of the exception. To qualify for protection, a bid or offer must be a quotation in an NMS stock (which is a security, other than an option, for which transaction reports are collected, processed and made available pursuant to an effective transaction reporting plan) that:

•: is displayed by an automated trading center and available for automatic execution;
•: is disseminated pursuant to an effective national market system plan; and
•: is an automated quotation that is the best bid or best offer of a national securities exchange, the best bid or best offer of Nasdaq, or the best bid or best offer of a national securities association other than the best bid or best offer of Nasdaq.

An "automated trading center" is essentially a market that executes an incoming order on an immediate basis without human intervention. A trade-through is defined as the purchase or sale of an NMS stock during regular trading hours at a price lower than a protected bid or higher than a protected offer. Displayed bids and offers not immediately accessible through automatic execution will not be protected from being traded through by any market under the Order Protection Rule. The Order Protection Rule also extends the trade-through provisions to Nasdaq-listed stocks.

Access Rule. The Access Rule sets forth new standards governing access to quotations in NMS stocks. It requires fair and non-discriminatory access to quotations and establishes a limit on access fees to harmonize the pricing of quotations across different trading centers. Specifically, the Access Rule establishes a limit on the access fees charged by trading centers when incoming orders execute against their displayed quotes and undisplayed interests at the best bid or offer to $0.003 per share (30 cents per 100 shares executed) or, if the price of the best bid or offer is less than $1.00, to no more than 0.3% of the quotation price per share. The Access Rule also requires SROs to establish, maintain and enforce rules that require their members to reasonably avoid displaying quotes that lock or cross any protected quotation in an NMS stock, or manual quotations that lock or cross quotations in NMS stocks and prohibit their members from engaging in a pattern or practice of displaying quotations that lock or cross quotations. A locked market occurs when, for example, the displayed price to buy a stock in one market is the same as the displayed price to sell the stock in another market. A crossed market occurs when the displayed price to buy a stock in one market is higher than the displayed price to sell the stock in another market.

Market Data Rules and Plans. Regulation NMS updates the requirements for consolidating, distributing, and displaying market information, as well as amending the joint industry plans for disseminating market information to modify the formulas for allocating plan revenues and broaden participation in plan governance. The new formula allocates revenues to market centers based on the value of the quotes and trades for all securities rather than the current formula, which is based simply on the number of trades (as it relates to exchange-listed securities) or a combination of trades and shares (as it relates to Nasdaq-listed securities). The new rule gives market centers and their members the ability to distribute their own data independently with or without charging fees. However, market centers will still be required to provide their best bids and offers and last sale information for consolidated dissemination through the joint-industry plans. The Market Data Rule also requires the SROs participating in the market data consolidation systems to create advisory committees composed of non-SRO representatives to the joint industry plans.

Sub-Penny Rule. The Sub-Penny Rule prohibits market participants from displaying, ranking, or accepting bids and offers in NMS stocks that are priced in an increment of less than $0.01, unless the price of the quotation is less than $1.00.

177

European Regulation

Overview

Euronext (through its subsidiaries) operates exchanges in five European countries. Each of the Euronext exchanges holds an exchange license granted by the relevant national exchange regulatory authority and operates under its supervision. Each market operator is also subject to national laws and regulations in its jurisdiction in addition to the requirements imposed by the national exchange authority and, in some cases, the central bank and/or the finance ministry in the relevant European country.

In addition, the national regulators of the Euronext exchanges are parties to two Memoranda of Understanding ("MOUs") designed to ensure coordinated supervision and regulation of Euronext N.V. and of the markets operated by the group. The principal forum for the coordinated supervision is a committee consisting of the chairmen of the national regulatory authorities (the "Chairmen's Committee"), which has approval or veto rights over a set of actions or decisions by Euronext delineated in the MOUs.

Euronext N.V. itself, as the holder of a joint exchange license with Euronext Amsterdam, is subject to the regulation and supervision of the Dutch Minister of Finance and the Dutch AFM in accordance with Dutch securities law and the terms and conditions of the joint exchange license.

The regulatory framework in which Euronext operates is substantially influenced and partly governed by European directives in the financial services area. The baseline directive applicable in the area is the Investment Services Directive of May 10, 1993. In 1999, the European Union adopted a Financial Services Action Plan ("FSAP") designed to create a single market for financial services by harmonizing the member states' rules on securities, banking, insurance, mortgages, pensions and all other financial transactions. In order to implement the FSAP, the European Union adopted the following key directives:

•: the Market Abuse Directive of January 28, 2003 (the "Market Abuse Directive");
•: the Prospectus Directive of November 4, 2003 (the "Prospectus Directive");
•: the Transparency Directive of December 15, 2004;
•: the Takeover Directive of April 21, 2004;
•: the Markets in Financial Instruments Directive of April 21, 2004 ("MiFID"); and
•: the Capital Adequacy of Investment Firms and Credit Institutions Directive of October 11, 2005.

The progressive implementation by European member states of some or all of these directives is enabling and increasing the degree of harmonization of the regulatory regime with respect to financial services, offering, listing, trading and market abuse. In addition, the implementation of the MiFID directive by the European member states is expected to result in a reinforcement of the regulators' authority and control over market operators' governance, shareholders and organization.

Regulation of Euronext Group

Group-Wide Supervision and Regulation. The national regulators of the Euronext exchanges are parties to two MOUs that provide a framework to coordinate their supervision of Euronext N.V. and of the markets operated by the Euronext group. The first MOU was initially entered into by the Dutch, French and Belgian exchange regulatory authorities in 2001 and was extended to the Portuguese exchange regulatory authority in 2002. The second MOU, which relates principally to the regulation of Euronext's derivatives markets, was entered into between such authorities and the UK exchange regulatory authority in 2003.

Within the framework of the first MOU, Euronext's continental European exchange regulators agreed to develop and implement a coordinated approach with respect to the supervision of Euronext markets, in particular with respect to the trading systems, registration and monitoring of trades, and dissemination of

178

market data, subject to the rights and obligations of each regulatory authority under the national laws of its home jurisdiction. The regulatory authorities that signed the MOUs cooperate on the basis of a multilateral memorandum of understanding with respect to the exchange of information and oversight of securities activities implemented by the Forum of European Securities Commissions ("FESCO") (now Committee of European Securities Regulators, or CESR). Representatives of Euronext's regulatory authorities meet in working groups on a regular basis in order to coordinate their actions in areas of common interest and agree upon measures to promote harmonization of their respective national regulations.

The principal forum for coordinated supervision under the MOUs is the Chairmen's Committee, which is composed of the chairmen of each of the signatory regulatory authorities. The Chairmen's Committee takes decisions by consensus. The Chairmen's Committee holds regular meetings with members of Euronext's Managing Board, and also meets on an ad hoc basis whenever necessary. A Steering Committee created under the MOU and consisting of representatives of each signatory authority meets prior to each meeting of the Chairmen's Committee, and may create working groups focusing on specific aspects of the regulation of Euronext. Certain delineated actions or decisions either require the prior approval of or are subject to the non-opposition of the Chairmen's Committee, or must be notified to the Steering Committee. Following a decision by the Chairman's Committee or the Steering Committee, the members of such committees are required to recommend to the decision-making bodies of each regulatory authority to approve and adopt, and otherwise act in accordance with, the decision of the relevant committee under the MOU. Matters not specifically delineated in the MOUs are reserved to the national regulators.

Decisions requiring prior approval of the Chairmen's Committee include entering into alliances, mergers, cross shareholdings and cross-membership agreements, performing certain integration and restructuring steps, listing of shares of Euronext or its subsidiaries, outsourcing activities related to trading, registration and publication of transactions, surveillance of trading members' activity or monitoring of transactions, creating or closing a regulated market or other trading facilities and approving or modifying the bylaws of Euronext N.V. or its subsidiaries. In addition, the Chairmen's Committee must approve any modifications to the Euronext Rulebook (which is described below).

Decisions subject to the non-opposition of the Chairmen's Committee include issuing notices interpreting or implementing provisions of the Euronext Rulebook and appointing (i) members of Euronext's managing board and supervisory board and (ii) key personnel.

Decisions requiring notification to the Steering Committee include the admission, sanction, suspension or exclusion of a market member, and certain other decisions such as listing or delisting of a financial instrument, suspension of trading, or other events that may be agreed between the signatory authorities.

Regulation of Euronext N.V. At the time that Euronext N.V. was formed in 2000, Euronext N.V. received a joint exchange license together with Euronext Amsterdam to operate regulated markets. As a result, Euronext N.V. is subject to the regulation and supervision of the Dutch Minister of Finance and the Dutch AFM, in accordance with Dutch securities law and the terms and conditions of the exchange license. The Dutch Minister of Finance's and the AFM's powers include a veto/approval right over (i) the direct or indirect acquisition of more than 10% of the shares of Euronext N.V., (ii) the appointment of the top management of Euronext N.V., (iii) any mergers, cross-shareholdings and joint ventures, and (iv) any actions that may affect the proper operation of the Dutch exchanges.

National Regulation

Euronext's European market operators hold licences for operating the following European Union regulated markets:

•: Euronext Amsterdam operates two regulated markets: one stock market (Eurolist by Euronext) and one derivatives market (the Euronext Amsterdam Derivatives Market);
•: Euronext Brussels operates three regulated markets: two stock markets (Eurolist by Euronext and the Trading Facility) and one derivatives market (the Euronext Brussels Derivatives Market);
•: Euronext Lisbon operates two regulated markets: one stock market (Eurolist by Euronext) and one derivatives market (the Portuguese Futures and Options Market);
•: Euronext Paris operates three regulated markets: one stock market (Eurolist by Euronext) and two derivatives markets (MONEP and MATIF); and
•: LIFFE Administration and Management operates one regulated market, a derivatives market (the London International Financial Futures and Options Exchange).

Each market operator also operates a number of markets that do not fall within the EU definition of "regulated markets" (described in this document as "non-regulated markets"). Each market operator is subject to national laws and regulations pursuant to its market operator status.

Euronext Amsterdam. Under section 22 of The Dutch Act on the Supervision of the Securities Trade 1995, the establishment of a recognized securities exchange in the Netherlands is subject to prior authorization by the Dutch Minister of Finance who may, at any time, amend or revoke this authorization if necessary to ensure the proper functioning of the markets or the protection of investors. Authorization may also be revoked for non-compliance with applicable rules.

AFM, together with De Nederlandsche Bank (DNB), acts as the regulatory authority for members of Euronext Amsterdam, supervises the primary and secondary markets, ensures compliance with market rules and monitors clearing and settlement operations. The Dutch Minister of Finance authorizes the recognition of exchanges, ensures compliance with EU directives, and issues declarations of no objection in connection with the acquisition of significant shareholdings in Euronext or Euronext Amsterdam.

On July 1, 2005, Euronext Amsterdam relinquished its responsibility for approving prospectuses of companies seeking listing on the exchange. This authority was transferred to the AFM, pursuant to the implementation of the Prospectus Directive. Euronext Amsterdam is still responsible for admitting financial instruments to listing on its markets. It is also in charge of establishing, monitoring compliance with and enforcing rules governing its primary markets. Responsibility for dealing with market abuse was transferred to the AFM on October 1, 2005, pursuant to the implementation of the Market Abuse Directive.

Euronext Brussels. Euronext Brussels is governed by the Belgian Act of August 2, 2002, which became effective on June 1, 2003 and is recognized as a market undertaking according to article 16 of this Act. The Belgian Act of August 2, 2002 transferred to the CBFA some of the responsibility previously executed by the Brussels exchange (e.g., disciplinary powers against members and issuers, control of sensitive information, supervision of markets, and investigative powers). Euronext Brussels continues to be responsible for matters such as the organization of the markets and the admission, suspension and exclusion of members and has been appointed by law as a "competent authority" within the meaning of the Listing Directive. Euronext Brussels, also governs three non-regulated markets: the Marché Libre (created in October 2004), the Public Auction Market for non-listed companies and Alternext (created in 2006).

Euronext Lisbon. Euronext Lisbon is governed by the Decree of Law no. 394/99 of October 13, 1999 (Regime Jurídico das Entidades Gestoras de Mercados, de Sistemas de Liquidaqão e de sistemas centralizados de valores mobilários), which, along with the Portuguese Securities Code and the CMVM regulations,

180

governs the regime for regulated and non-regulated markets, market operators and all companies with related activities. This law was amended on January 15, 2002 (Decree of Law no. 8-D/2002 of January 15) to allow Euronext to acquire all the shares of the Bolsa de Valores de Lisboa e Porto, the Lisbon and Porto Exchange ("BVLP") and to allow an amendment to the articles of association of BVLP, which, until that date, restricted voting rights to 15%. The creation of regulated market companies requires the prior authorization in the form of a decree from the Portuguese Minister of Finance, following consultation with the CMVM. The CMVM, Euronext Lisbon's national regulator, is an independent public authority that monitors markets and market participants, public offerings and collective investment undertakings. In addition, a regulated market must be registered with the CMVM prior to starting operations. The Portuguese Minister of Finance may withdraw recognition of a regulated market in certain cases stipulated in the above-mentioned law.

Euronext Paris. Euronext Paris is governed by French Law no. 96-597 dated July 2, 1996 (which implemented the European Investments Services Directive in French law), as amended, and codified in the French Monetary and Financial Code. Under the French Monetary and Financial Code, the French Minister of Finance has the authority to confer or revoke regulated market status upon recommendation of the AMF and following an opinion from the Banque de France. Market status is granted if the market meets specific conditions for proper operation. In particular, the market must have rules governing access to the market, listing of securities, the organization of trading, the suspension of trading, and the recording and publication of trades. The AMF is responsible for safeguarding investments in financial instruments and in all other savings and investment vehicles, ensuring that investors receive material information, and maintaining orderly financial markets. It establishes the rules of conduct that must be observed by market operators and their personnel, determining the conditions for granting or revoking professional licenses for individuals acting on behalf of market operators, and establishing the general principles for the organization and operation of regulated markets. It is also responsible for formulating the rules governing the execution and publication of transactions involving securities or futures and options contracts listed on these markets. It also has the authority to regulate and monitor companies' initial public offerings (i.e., vetting of prospectuses), financial communication of listed companies and tender offers. It can oppose the decision of a market operator to admit a security or a futures and/or option contract to trading on the operator's market or to delist a security.

Furthermore, as mentioned above, the AMF makes recommendations to the French Minister of Finance on conferring regulated market status. Finally, the AMF approves the rulebooks of regulated markets. All amendments to the rulebooks of a regulated market are subject to the prior approval of the AMF following an opinion from the Banque de France. The AMF is also empowered to establish standards for certain non-regulated markets or obligations for persons having made forms of public offerings other than listing on a regulated market, which may be relevant for the operation of non-regulated markets by Euronext Paris (notably Alternext and the Marché Libre).

In addition to its status as a market operator, Euronext Paris is approved as a specialized financial institution and is therefore governed by French banking legislation and regulations (notably the French Banking Act as amended and codified in the French Monetary and Financial Code), which means that it is subject to supervision by the CECEI and the French Banking Commission ("Commission Bancaire"). As such, it must comply with certain prudential ratios and requirements including prudential equity minimum requirements and solvency ratios.

LIFFE. LIFFE (Holdings) plc, a UK company, is governed by the UK Companies Acts of 1985 and 1989. LIFFE (Holdings) shares are held by Euronext UK plc, a subsidiary of Euronext N.V. LIFFE (Holdings) has three principal regulated subsidiaries: LIFFE Administration and Management and LIFFE Services Ltd in the UK, and NQLX LLC in the United States.

LIFFE Administration and Management ("LIFFE") administers the markets for financial and commodity derivatives in London, which are overseen by the U.K. FSA. In the UK, financial services

181

legislation comes under the jurisdiction of Her Majesty's Treasury, while responsibility for overseeing the conduct of regulated activity rests with the FSA. Under current legislation, LIFFE is designated as a recognized investment exchange pursuant to the U.K. Financial Services and Markets Act 2000. As such, LIFFE is required to maintain sufficient financial resources for the proper performance of its functions (requirement to hold at least £52 million of cash in its assets based on 2005 financials).

LIFFE Services Limited is primarily a technology supplier and is governed by FSA regulations as a service company.

NQLX LLC is a wholly owned indirect subsidiary of LIFFE (Holdings), which is notice-registered with the SEC and is regulated by the CFTC as a designated contract market. NQLX LLC is currently dormant but has retained its status as a designated contract market in anticipation of listing new contracts in the future.

Additional National Regulation. The rules set forth below relating to the acquisition of an interest in a market operator apply to both direct and indirect acquisitions and, to the extent that Euronext holds directly or indirectly 100% of its five market operator subsidiaries, also apply to the acquisition of an interest of the same size in Euronext. Following completion of NYSE Euronext's offer for Euronext, such rules will also apply mutatis mutandis (depending on the interest held by NYSE Euronext in Euronext) to NYSE Euronext. These rules are specific to market operators (and their holding companies) and are in addition to shareholder reporting rules applicable to listed companies generally.

•: Under Dutch law, no shareholder may hold or acquire, directly or indirectly, or try to increase its stake to more than 10% of a recognized market operator without first obtaining a declaration of no-objection from the Dutch Minister of Finance.
•: Under French law, the acquisition and divesture by any person or group of persons acting in a concerted manner of 10%, 20%, 33 1/3% or 50% of Euronext Paris shares or voting rights must be authorized by the CECEI. By exception to the above, in the event that the acquisition or divesture of shares takes place outside of France between non-French persons, such acquisition or divesture need only be notified to the CECEI, which, if it determines that such transaction could adversely affect the fit and proper management of Euronext Paris, could decide to review and amend Euronext's credit institution license.
•: Also under French law, any person or group of persons acting in a concerted manner who acquires Euronext Paris shares or voting rights in excess of 10%, 20%, 33 1/3%, 50% or 66 2/3% is required to inform the AMF. In addition, should the French Minister of Finance consider that the acquisition by an investor of an interest in Euronext Paris could adversely affect the proper functioning of the regulated market(s) it operates, the French Minister of Finance may decide that the acquired shares be deprived of their voting rights until the situation has been settled, and/or, under certain conditions, either amend or withdraw Euronext Paris' license to operate regulated markets.
•: A shareholder who intends to acquire a 10% interest in a market operator in Belgium must provide prior notice to the CBFA. Thereafter, the same obligation applies each time such a 10% shareholder intends to increase its ownership by an additional 5% (e.g., 15%, 20%, 25%, etc.).
•: Under Portuguese law, a shareholder who intends to acquire a dominant holding in a Portuguese market operator must obtain the prior authorization of the Portuguese Ministry of Finance. In addition, all entities acquiring or disposing of a holding (direct or indirect) in a market undertaking in Portugal at the level of 2%, 5%, 10%, 20%, 1/3, 50%, 2/3 and 90% of the voting rights, must notify the CMVM of the acquisition or disposal within three business days following the relevant transaction.
•: In the United Kingdom, the FSA requires that "recognised investment exchanges" (such as LIFFE) meet a "fit and proper" test taking into account, among other things, governance arrangements, integrity and competence of key personnel.

182

Harmonized Market Rules

As part of the process of integrating the trading platforms of its European markets, Euronext introduced a harmonized rulebook, which has reduced the compliance burden on users, ultimately reducing their costs. The Euronext Rulebook currently consists of two books:

•: Rulebook I contains the harmonized rules, including rules of conduct and enforcement rules that are designed to protect the markets, as well as rules on listing, trading and membership; and
•: Rulebook II contains the remaining rules of the individual markets that have not yet been harmonized or which pertain to a specific non-regulated market.

Notices adopted by Euronext under Rulebook I apply to all Euronext markets (unless otherwise specified), while those for Rulebook II are specific to local jurisdictions. Rulebook I covers the following matters:

•: membership rules for cash markets and derivative markets;
•: trading rules for cash markets and derivative markets;
•: listing rules for cash markets;
•: rules of conduct for cash markets and derivative markets;
•: transparency obligations for certain issuers (applicable only to cash markets); and
•: enforcement of the rules (applicable to cash markets and derivative markets).

Listing and Financial Disclosure

The regulatory authorities that are signatories to the aforementioned MOUs have agreed to use their best efforts to harmonize their respective national rules, regulations and supervisory practices regarding listing requirements, prospectus disclosure requirements, ongoing obligations of listed companies, take-over bid rules and disclosure of large shareholdings. The rules regarding public offerings of financial instruments and prospectuses as well as ongoing (ad-hoc and periodic) disclosure requirements for listed companies are set forth by the Prospectus Directive and Transparency Directive which must be implemented in Euronext countries by each legislative body and regulator. Companies seeking to list and trade their securities on a Euronext market must comply with the harmonized listing requirements of Rulebook I and, following admission, with the ongoing disclosure requirements applicable in the country in which the relevant market is located.

Companies may apply for admission to listing and trading in one or more jurisdictions in which a Euronext market is located. However, a single point of entry for issuers allows investors from other Euronext countries to have access to the order book as far as trading is concerned. (The settlement processes may still differ among the various Euronext markets but are being integrated and harmonized within the Euroclear group settlement systems.)

Membership and Compliance

Euronext offers to its members the ability to extend membership across all Euronext jurisdictions, subject to the fulfillment of technical conditions that may include adequate local clearing and settlement arrangements and the satisfaction of applicable regulatory requirements. With regard to investment service providers, this common membership is achieved through the "ISD passport" (i.e., the right to provide services or establish a branch in the host country based on the ISD license granted in the home country). As for the persons that do not benefit from this passport (because their activity does not call for a license under the ISD or due to their extra-European origin), Euronext regulators have put in place arrangements which aim at creating a "proxy passport" whereby the diligence conducted by one of the relevant European

183

authorities to authorize a person to conduct its business as a trading member can be relied upon by the other authorities, within the limits of the sovereignty of each signatory authority.

Pending clarification of the respective roles of the home and host countries by the implementation of MiFID and related European directives and regulations, members may have to comply with some conduct of business rules imposed by the host state. In particular, when dealing with persons located in host states, members must comply with rules relating to marketing, solicitation, public offers, conduct of business and customer protection mandated by host states, and any other mandatory rules provided by host state authorities.

Euronext may suspend a member's trading privileges if the member has breached a rule in the Euronext Rulebook or any of the conditions attached to its membership. Euronext may also decide to terminate membership under certain circumstances, including the loss of a member's license or authorization as an investment firm issued by the competent authority of its home state or the violation of any rules of the Euronext Rulebook or the admission agreement.

Trading and Market Monitoring

The Investment Services Directive, the Market Abuse Directive, CESR standards and the Euronext Rulebooks all provide minimum requirements for monitoring of trading and enforcement of rules by Euronext as a regulated market. Euronext has set up a framework to organize market monitoring by which it:

•: monitors trading in order to identify breaches of the rules, disorderly trading conditions or conduct that may involve market abuse;
•: reports to the local regulator breaches of rules or of legal obligations relating to market integrity; and
•: monitors compliance with and enforces Euronext rules pursuant to FESCO standards and the Euronext Rulebooks.

Market surveillance and monitoring are implemented through a two-step procedure consisting of real time market surveillance performed by departments of the SBUs and a "next day" analysis of the executed trades. In addition, the compliance department monitors Euronext members by conducting on site investigations and inspections to ensure that members comply with Euronext rules.

Intra-day monitoring of the markets is performed by Cash Market Operations ("CMO") and by Derivatives Market Operations ("DMO"). CMO and DMO are the day-to-day first lines of contact for all market participants (members, issuers and regulators) in respect of operational issues. They monitor day-to-day activity and can take immediate action aimed at maintaining fair and orderly markets. This monitoring triggers preventive and immediate action when the functioning of the orderly market is threatened and market rules are not complied with.

Within SBUs, market operations enforce all rules relating to trading activity including the provisions of Chapter 8 of the Euronext Rulebook I (relating to rules of conduct) on a real time basis. In this manner, cases of market abuse are reported to the competent regulator (who is responsible for enforcing the Market Abuse Directive provisions in accordance with national laws and regulations) and possible infringement of Euronext rules is reported to the compliance department.

Euronext's market supervision department is responsible for the monitoring the trading on all markets on a next day basis in order to monitor the detection of possible cases of market abuse and possible infringements of the Euronext rules.

Euronext's compliance department is responsible for the conduct of on site member inspections and investigations, and handles infringement to Euronext rules by enforcing Chapter 9 of the Euronext Rulebook I.

NYSE Euronext's Competitive Strengths

NYSE Euronext will combine the strengths of NYSE Group and Euronext. However, NYSE Euronext anticipates that its strength as a combined entity will be more than the strength of its parts, and that the integration of NYSE Group and Euronext will create the following additional strengths for the benefit of all stakeholders including shareholders, issuers, and investors:

World's Largest Cash Equities Market. NYSE Euronext will maintain the world's largest pool of liquidity for cash equities and operate the world's most sizable market for listing and trading cash equity securities, which NYSE Euronext believes will drive innovation and efficiency for investors and issuers. During the period January-June, 2006, according to statistics published by the World Federation of Exchanges, the average daily value of cash equity securities traded on the exchanges operated by NYSE Group or Euronext was $105.9 billion, which was greater than the average daily trading value of securities traded on other cash equity exchanges including Nasdaq ($41.4 billion), the London Stock Exchange ($30.0 billion), the Tokyo Stock Exchange ($26.1 billion), and the Deutsche Börse ($11.6 billion).

World's Most Global Exchange Group. NYSE Euronext will provide optimum choice for its customers, operating six cash equity and two derivative exchanges in six countries, rendering it the world's most global securities exchange. On a combined basis, NYSE Euronext's exchanges will trade securities in two of the world's three leading global currencies, the U.S. dollar and Euro. NYSE Euronext will operate two cash equity exchanges in the United States including NYSE and NYSE Arca, and four cash equity exchanges in continental European countries including Belgium, France, the Netherlands, and Portugal. NYSE Euronext will also operate derivative exchanges trading a wide range of products in the United States through NYSE Arca, and in Europe through Euronext.Liffe.

World's Leading Listings Venue. As of June 30, 2006, the total global market capitalization, on a combined basis, of NYSE Group and Euronext's listed companies was approximately $25.2 trillion, greater than the combined value of the London Stock Exchange ($8.9 trillion), the Tokyo Stock Exchange ($6.3 trillion), Nasdaq ($4.3 trillion), and the Deutsche Börse ($3.2 trillion). In addition, on a combined basis NYSE Euronext will list more of the world's largest companies than any other exchange group in the world. As of June 30, 2006, on a combined basis, NYSE Group and Euronext listed, on a primary or secondary basis, 82 of the world's 100 largest companies, based on market capitalization, compared to 39

185

such companies listed on the London Stock Exchange, 21 listed on the Swiss Exchange, 20 listed on the Tokyo Stock Exchange, 14 listed on the Deutsche Börse, and 11 listed on Nasdaq. In addition, NYSE Euronext will also be well-positioned among the emerging growth countries of Brazil, Russia, India and China (collectively referred to as the "BRICs"), listing more companies from the BRICs than any other exchange group in the world. As of June 30, 2006, on a combined basis, NYSE and Euronext listed 62 companies from the BRICs, compared to 35 such companies listed on the London Stock Exchange, 32 on Nasdaq, and none on the Deutsche Börse.

Broad Range of Products and Services: NYSE Euronext will provide its customers with an unparalleled range of products and services within the global exchange industry, spanning across a number of asset classes and market segments.

In addition, NYSE Euronext or its subsidiary will offer trading in a range of other derivatives including short and long term interest rates, equity and fixed income indices, single stock futures and commodities.
•: Listings: NYSE Euronext will facilitate the capital formation process for companies around the world by supporting multiple venues for a diverse range of issuers to list in both the United States through NYSE and NYSE Arca, and in Europe through Euronext and Alternext.
•: Market Data and Indices: NYSE Euronext's breadth of product offerings will create new opportunities to offer customers a broader array of market data services that leverages the company's unique global presence across multiple product classes.

Commitment to Cooperative, Multilateral Regulation. NYSE Euronext is committed to cooperative, multilateral regulation, yet it will maintain the strong and effective local regulatory frameworks that have been successfully established within the United States and among the College of Regulators within Europe. NYSE Euronext recognizes that the existing local regulatory frameworks play an invaluable role in enhancing the value and reputation of NYSE Group and Euronext, as well as their respective listed companies and member organizations.

186

NYSE Euronext's Strategy

NYSE Euronext plans to build on its status as the preeminent global exchange by executing a clearly defined strategy:

Extend Range of Products and Services. The combination of NYSE Group and Euronext will provide NYSE Euronext with an opportunity to diversify and realize significant revenue synergies by leveraging the combined company's premier brand name, unparalleled product range, global customer base, and leading technology platforms. NYSE Euronext has identified new revenue opportunities that are expected to generate $100 million in incremental revenues annually within three years. These new opportunities will be derived by developing new products and services in a number of areas including:

•: Cash Equities Trading. It is expected that within three years, NYSE Euronext will generate $35 million in new revenues annually by capitalizing on its position as the world's largest and most liquid equities market, and by providing its customers with innovative trading products and services in a number of areas including meeting European demand to invest in the leading public companies in the United States, cross-fertilizing product development opportunities in the rapidly growing areas of structured products and exchange-traded funds, and extending trading hours across time zones.
•: Derivatives. NYSE Euronext expects to generate $45 million in new derivatives revenues annually through a number of initiatives including cross-selling derivative products among the current customer bases of NYSE Group and Euronext, extending the highly successful European wholesale over-the-counter derivatives services currently provided by Euronext to the United States, and launching a number of new products such as trans-Atlantic indices and corporate credit derivatives.
•: Listings. NYSE Euronext will leverage its premier brand and position as the world's leading listings venue with the deepest global pool of liquidity to compete aggressively for new listings on a global scale. It is expected that these initiatives will generate incremental annual revenues for NYSE Euronext of $20 million within three years. With multiple listings platforms in both the United States (NYSE and NYSE Arca) and Europe (Euronext and Alternext), NYSE Euronext will be uniquely situated to target a highly diverse range of companies from around the world to facilitate the capital raising process. Among other things, the combined company will leverage the NYSE Euronext brand to capture listings from around the world, develop a Euro-denominated Global Depository Receipts program to provide issuers in the United States with an ability to leverage Euronext's European liquidity pools, and position Alternext as a viable and compelling competitor to the London Stock Exchange's AIM market for international small cap issuers.
•: Market Data and Indices. NYSE Euronext will generate significant volumes of market data in a variety of products, presenting an opportunity to leverage this data more profitably by aggregating, analyzing, packaging and distributing it to a broader base of customers in new and different ways.
•: Trading Software. NYSE Euronext will also seek to capitalize on its highly diversified business mix to develop new revenue opportunities in areas such as trading software.

Maximize Customer Choice. Leveraging its position as the world's leading cash equities marketplace and a significant participant in the global derivatives markets, NYSE Euronext will provide a full-service market that offers its customers a choice of products across asset classes that appeals to all types of investors worldwide. NYSE Euronext believes that this combination will help to maintain its leadership position, enhance its ability to compete on a global scale, and deliver innovation and efficiency.

Leverage Technology to Drive Cost Reductions and Integration Benefits. NYSE Euronext expects to benefit from operational synergies resulting from the consolidation of capabilities and elimination of redundancies as well as greater efficiencies from increased scale, market integration, and automation. The combination is expected to create significant cost reductions of $275 million annually within the next three years. Of this amount, $250 million will result from the overall rationalization of the combined company's

187

information technology systems and platforms, driven by the high level of compatibility among the current technology platforms maintained by NYSE Group and Euronext. Based on Atos Euronext Market Solutions' leading technology and the management team's proven integration track record, over the next three years NYSE Euronext's three cash trading systems (NYSE, NYSE Arca, and Euronext's NSC system) and three derivatives trading systems (NYSE's PCX+ and OX platforms, and Euronext's LIFFE CONNECT® platform) will be migrated to a single global cash and a single global derivatives platform. In addition, 10 data centers (six in the United States and four in Europe) will be reduced to four globally-linked data centers (two in the United States and two in Europe), and four data networks will be reduced to one. NYSE Euronext will also deliver annual cost savings of $25 million from the rationalization of non-information technology related activities including the integration of corporate support functions such as finance and human resources, and the streamlining of marketing and other corporate costs such as insurance, occupancy and professional services.

Pursue Strategic Acquisitions and Alliances. As the world's largest and most recognized brand name within the global exchange group, NYSE Euronext is extremely well-positioned to play a leadership role in the ongoing consolidation of the industry through acquisitions and strategic alliances. NYSE Euronext believes it is a partner of choice among global exchanges, and it is expected that NYSE Euronext management will continually explore and evaluate strategic acquisitions, alliances, partnerships and other commercial agreements that could provide NYSE Euronext with opportunities to enhance its global competitive position by strengthening its brand and diversifying its business activities and revenue streams.

Benefits for All Stakeholders. The establishment of NYSE Euronext is expected to create significant value for all of its stakeholders, including the following.

•: Shareholders are expected to benefit from the significant value and financial strength created by combining two market leaders in the global exchange industry with highly compatible technology platforms and business models. As a result of the combination, NYSE Euronext will deliver substantial revenue synergies and cost savings to its shareholders, driving increased profitability, revenue and earnings growth, and cash flow.
•: Investors and the trading community are expected to benefit from NYSE Euronext's horizontal business model and global trading capabilities that extend across multiple asset classes through seven exchanges in six countries. The depth of NYSE Euronext's liquidity pools, combined with best in class technology platforms and new product development opportunities will lead to enhanced trading options for investors while providing the opportunity for improved market quality and lower transaction costs.
•: Issuers are expected to benefit from their affiliation with NYSE Euronext, the world's leading listing brand that maintains the largest pool of liquidity and provides access to investors in both the United States and Europe.

Competition

The securities markets are intensely competitive, and competition may be expected to further intensify. NYSE Euronext will have numerous aggressive competitors, both domestically and around the world. It will compete with other markets, electronic communication networks, market-makers and other execution venues based on best price, depth of liquidity, all-in cost, anonymity, speed, functionality and certainty of execution. In addition to competition from alternate trading venues, NYSE Euronext will compete in the provision of its services with other exchanges, in the U.S. and internationally. Because some of NYSE Euronext's prospective competitors are not registered securities exchanges, they will operate with less regulatory oversight than NYSE Euronext, enabling them to move with greater agility in response to changes in the markets or economic environment.

188

NYSE Euronext's principal U.S. competitors for trading listed equity securities will include Nasdaq, which in 2005 completed its acquisition of INET ECN, the American Stock Exchange, regional U.S. exchanges such as the Chicago Stock Exchange, the Boston Stock Exchange and the Philadelphia Stock Exchange. Internationally, NYSE Euronext will also face competition for listings from a number of stock exchanges including London Stock Exchange plc, Deutsche Börse Group, and exchanges in Tokyo, Hong Kong, Toronto, Singapore and Australia. Furthermore, NYSE Euronext's competitors may expand into markets in which NYSE Group and Euronext are currently active. For example, well-capitalized, highly profitable non-U.S. exchanges such as the Deutsche Börse Group have already entered the U.S. market and may seek to expand their presence. NYSE Euronext will also compete with electronic communication networks and alternative trading systems such as POSIT, Liquidnet and E-crossnet. In addition, NYSE Euronext will also face competition from major customers and brokers that may either internalize order flow or transact orders through bilateral agreements. See "Risk Factors—Risks Relating to NYSE Euronext's Business—NYSE Euronext will face numerous competitors in the United States, Europe and the rest of the world."

NYSE Euronext's principal competitors for the trading of fixed income securities will be the participants active on the OTC markets, in particular IDBs such as ICAP plc and eSpeed Inc., and multi-dealer trading platforms such as MarketAxess, BondDesk, TradeWeb, and Bloomberg Electronic Trading. In relation the trading of derivatives, the principal competitive constraint on NYSE Euronext will be exercised by the OTC markets, although NYSE Euronext will also continue to compete with a number of other derivatives exchanges, including the International Securities Exchange, Inc., the Chicago Board Options Exchange, Inc., the American Stock Exchange, and Eurex, the derivatives platform operated by Deutsche Börse.

Additional potential competitors might be created if the consolidation trend in the securities trading industry continues and other companies form joint ventures or consortia to provide services similar to those that will be provided by NYSE Euronext, or become competitive with NYSE Euronext through acquisitions. NYSE Euronext may also face competition from new entrants into the markets in which it competes, or from new initiatives from existing market participants, including established securities markets or exchanges. For example:

•: On April 11, 2006, Nasdaq announced that it had purchased 14.99% of the outstanding shares of the London Stock Exchange, following the withdrawal on March 30, 2006 of its previously launched takeover bid for the London Stock Exchange. On May 3, 2006, Nasdaq announced that it had increased its ownership interest in the London Stock Exchange to 18.7%. Nasdaq has since increased its ownership stock to 25.3% as of August 15, 2006.

On July 24, 2006, the ISE Stock Exchange announced that Nomura Securities, Van der Moolen, and E-Trade Financial had also joined the ISE Stock Exchange as strategic partners. ISE Stock Exchange launched its first product during the third quarter of 2006.
•: On April 20, 2006, Liquidnet announced that nine firms will be providing liquidity directly to its H20 trading system, including Bloomberg Tradebook, BNY Brokerage (a subsidiary of The Bank of New York), Instinet, FutureTrade, Miletus Trading, Piper Jaffray, EdgeTrade, UNX, and Goldman Sachs Execution & Clearing (a subsidiary of Goldman Sachs).
•: On July 27, 2006, the Chicago Board Options Exchange announced that it is entering the cash equities market through the formation of the CBOE Stock Exchange LLC in conjunction with several strategic partners including Interactive Brokers, LaBranche & Co., Susquehana

189

•: On July 30, 2006, the Chicago Stock Exchange announced that it received investments from several strategic partners including Bank of America, Bear Stearns, E-Trade Financial, and Goldman, Sachs.
•: On September 6, 2006, the National Stock Exchange announced the sale of a majority stake to a group of strategic investors including Bear Stearns, Citigroup, Credit Suisse, Merrill Lynch, Bloomberg Tradebook, and Knight Capital.
•: Eight large European-based investment banks announced in July 2006 their intention to launch a European-made reporting facility called "BOAT" to compete with the reporting services offered by the European exchanges including Euronext.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA FOR NYSE EURONEXT

The following unaudited pro forma condensed combined financial data and explanatory notes present how the consolidated financial statements of NYSE Euronext may have appeared had Archipelago, PCX Holdings, the NYSE and Euronext actually been combined at earlier dates. The unaudited pro forma condensed combined financial data shows the impact of the combinations on the companies' respective historical financial positions and results of operations under the purchase method of accounting with Archipelago treated as the acquirer of PCX Holdings, the NYSE treated as the acquirer of Archipelago, and NYSE Group treated as the acquirer of Euronext, and as if the acquisition of PCX Holdings by Archipelago, the acquisition of Archipelago by the NYSE and the acquisition of Euronext by NYSE Group had been completed on January 1, 2005 for statement of income purposes and on June 30, 2006 for statement of financial condition purposes.

On September 26, 2005, Archipelago completed the acquisition of PCX Holdings for a total purchase price of approximately $94.0 million consisting of a $90.9 million cash payment to PCX Holdings stockholders and certain PCX Holdings employees, and approximately $3.1 million of direct costs incurred by Archipelago as part of this acquisition. The $90.9 million cash payment represented the total dollar value of 1,645,415 shares of Archipelago common stock held by the Pacific Exchange at the time of the closing, or $66.3 million (calculated based on the average closing price of Archipelago's stock price on NYSE Arca for the ten trading days prior to the acquisition of PCX Holdings), plus $24.6 million.

On March 7, 2006, Archipelago and the NYSE combined their businesses and became wholly-owned subsidiaries of NYSE Group, a newly created, for profit and publicly traded holding company. Each of the 1,366 members of the NYSE received $300,000 in cash and 80,177 shares of NYSE Group common stock in exchange for its NYSE membership. In addition, a cash dividend of $70,571 was declared and paid to each of the 1,366 members. The aggregate number of shares of NYSE Group common stock issued to all of the NYSE members and Archipelago stockholders in the merger equaled 70% and 30%, respectively. The total merger consideration, which was determined based on the fair market value of Archipelago common stock beginning two days before and ending after April 20, 2005 (the date the merger was agreed to and announced), was $1,085.1 million.

In the NYSE Euronext combination, NYSE Group and Euronext will combine their businesses under NYSE Euronext, a Delaware corporation. Euronext's business will be brought under NYSE Euronext through an exchange offer and a post-closing reorganization, and NYSE Group's business will be brought under NYSE Euronext through a merger. In the exchange offer, NYSE Euronext or a subsidiary of NYSE Euronext will offer to acquire each outstanding Euronext ordinary share in exchange for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. The exchange offer also will have a mix and match election to permit Euronext shareholders to elect all cash or all stock in exchange for their Euronext ordinary shares, subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all exchanging Euronext shareholders received the standard offer consideration.

For accounting purposes, the acquisition of PCX Holdings by Archipelago and the acquisition of Archipelago by the NYSE were treated under the purchase method of accounting and the assets acquired and liabilities assumed were recorded at their estimated fair value. The combination of NYSE Group and Euronext will also be treated under the purchase method of accounting for accounting purposes, and Euronext's assets acquired and liabilities assumed will be recorded at their estimated fair value.

The allocations of the respective purchase price to Archipelago and Euronext's assets, including intangible assets, and liabilities are only preliminary allocations based on estimates of fair values and will change when estimates are finalized. Among the provisions of Statement of Financial Accounting Standards No. 141, "Business Combinations," criteria have been established for determining whether intangible assets should be recognized separately from goodwill. Statement of Financial Accounting

192

Standards No. 142, "Goodwill and Other Intangible Assets" ("SFAS 142") provides, among other guidelines, that goodwill and intangible assets with indefinite lives will not be amortized, but rather are tested for impairment on at least an annual basis.

The unaudited pro forma condensed combined statements of income do not include (1) any revenue or cost saving synergies that may be achievable subsequent to the completion of the business combinations, or (2) the impact of non-recurring items directly related to the business combinations.

The unaudited pro forma condensed combined statement of financial condition as of June 30, 2006 combines the June 30, 2006 historical statement of financial condition of NYSE Group and the June 30, 2006 historical statement of financial condition of Euronext and assumes that the combination of NYSE Group and Euronext took place on that date. The unaudited pro forma condensed combined statements of income for the year ended December 31, 2005 and for the six months ended June 30, 2006 assume that the three business combinations took place on January 1, 2005. Reclassifications have been made to the historical financial statements of NYSE Group and Euronext to conform to the presentation expected to be used by NYSE Euronext. NYSE Group and Euronext expect that there could be additional reclassifications following the combination.

The pro forma condensed combined financial data shown under this heading is unaudited, is presented for informational purposes only, and is not necessarily indicative of the financial position or results of operations that would actually have occurred had the acquisition of PCX Holdings by Archipelago, the acquisition of Archipelago by the NYSE and the acquisition of Euronext by NYSE Group been consummated as of the dates or at the beginning of the periods presented, nor is it necessarily indicative of future operating results or financial position. The unaudited pro forma condensed combined financial data shown under this heading and the accompanying notes should be read together with:

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1—Basis of Presentation

The unaudited pro forma condensed combined financial statements give effect to the following:

•: the acquisition of PCX Holdings by Archipelago, the acquisition of Archipelago by the NYSE and the acquisition of Euronext by NYSE Group in three separate transactions to be accounted for as purchase business combinations, with
•: Archipelago treated as the legal and accounting acquirer of PCX Holdings
•: the NYSE treated as the legal and accounting acquirer of Archipelago, and
•: NYSE Group treated as the legal and accounting acquirer of Euronext
•: the acquisitions of PCX Holdings by Archipelago, Archipelago by the NYSE and Euronext by NYSE Group as if the three business combinations had been completed on January 1, 2005 for statement of income purposes, and
•: the acquisition of Euronext by NYSE Group as if the business combination had been completed on June 30, 2006 for statement of financial condition purposes.

The unaudited pro forma condensed combined financial statements have been prepared based on the consolidated financial statements of NYSE Group and Euronext prepared in accordance with accounting principles generally accepted in the United States of America, and should be read together with the separate financial statements of NYSE Group and Euronext.

On September 26, 2005, Archipelago completed the acquisition of PCX Holdings. Based on the preliminary allocation of the purchase price in the PCX Holdings acquisition, the assets and liabilities of PCX Holdings were included in Archipelago's historical consolidated statement of financial condition as of June 30, 2006. The results of operations of PCX Holdings have been included in Archipelago's historical results of operations since October 1, 2005.

On March 7, 2006, the NYSE completed the acquisition of Archipelago. Based on the preliminary allocation of the purchase price in the Archipelago acquisition, the assets and liabilities of Archipelago were included in NYSE Group's historical consolidated statement of financial condition as of June 30, 2006. The results of operations of Archipelago have been included in NYSE Group's historical results of operations since March 8, 2006.

The unaudited pro forma condensed combined financial data is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the business combinations had been consummated during the period or as of the dates for which the pro forma data is presented, nor is it necessarily indicative of the future operating results or financial position of NYSE Euronext.

The NYSE's purchase price for Archipelago and NYSE Group's purchase price for Euronext have been allocated to the assets acquired and the liabilities assumed based upon management's preliminary estimate of their respective fair values as of the date of acquisition. Definitive allocations will be performed when estimates are finalized. Accordingly, the purchase price allocation pro forma adjustments are preliminary, have been made solely for the purpose of providing unaudited pro forma condensed combined financial data and are subject to revision based on a final determination of fair value after the closing of the business combination.

The accompanying unaudited pro forma condensed combined statements of income do not include (1) any revenue or cost saving synergies that may be achievable subsequent to the completion of the business combinations, or (2) the impact of non-recurring items directly related to the business combinations.

Note 1—Basis of Presentation (Continued)

The statement of financial condition of Euronext as of June 30, 2006 has been translated using an exchange rate of €1.00 = $1.2779. The statements of income of Euronext for the year ended December 31, 2005 and the six months ended June 30, 2006 have been translated using an average exchange rate of €1.00 = $1.2449 and €1.00 = $1.2309, respectively.

Certain reclassifications have been made to the historical financial statements of NYSE Group conform to the presentation expected to be used by NYSE Euronext. NYSE Group expects that there could be additional reclassifications following the combination.

Note 2—Purchase Price of Euronext

For the purpose of preparing the accompanying unaudited pro forma condensed combined statement of financial condition as of June 30, 2006, management made the following assumptions:

•: there were approximately 111.0 million shares of Euronext outstanding at June 30, 2006,
•: prior to June 30, 2006, each outstanding Euronext share received €3.00 (approximately $3.75) by way of repayment of share capital totaling approximately $415.0 million, and
•: each outstanding Euronext share was acquired on June 30, 2006 in exchange for (i) €21.32 (approximately $27.00) in cash for a total cash consideration of approximately $3.0 billion and (ii) 0.98 of a share of NYSE Euronext common stock.

Based on the above assumptions, the total purchase consideration was computed as follows:

	111.0 million shares
times	0.98
times	$61.70	[a]

Equity component	$6.65 billion

plus
	111.0 million shares
times	$27.00

Cash component	$3.00 billion

Acquisition costs	$50 million	[b]

Total purchase consideration	$9.7 billion

[a]: Corresponding to the average closing stock price of NYSE Group for the five-day period beginning two days before and ending two days after June 1, 2006 (the date the combination was agreed to and announced).
[b]: Corresponding to management's estimate of direct costs of acquisition to be incurred by NYSE Group.

The fair value of stock options and awards issued by NYSE Euronext in exchange for stock options and awards of Euronext will be included as part of the purchase consideration but has been disregarded for the presentation of this pro forma financial information due to its immateriality.

Residual goodwill created from business combination			5,748

Total purchase price		$	9,700

Note 3—Pro Forma Adjustments


[3.1]	To reverse the revenue recognized by PCX Holdings in relation to its exchange facility agreement with Archipelago. In May 2001, Archipelago acquired the right to operate as the exclusive equity trading facility of PCX Equities, including the rights to certain revenue streams comprised primarily of transaction fees, market data fees and listing fees, for an aggregate consideration of $90.0 million. Archipelago determined that this intangible asset had an indefinite life and, as such, it is not subject to amortization. PCX Holdings deferred the recognition of a portion of the consideration over a period of five years.
[3.2]	To reverse the regulatory oversight revenue recognized by the Pacific Exchange and corresponding regulatory fees incurred by Archipelago. Under the terms of the facility services agreement between the Pacific Exchange and Archipelago, Pacific Exchange provided certain regulatory services to Archipelago in return for regular payments as negotiated between the parties.
[3.3]	To reverse the registered representative fee revenue recognized by Archipelago (as contra routing and clearing fees) and corresponding expense recorded at PCX Holdings (as contra revenue). Prior to the acquisition of PCX Holdings by Archipelago, PCX Holdings forwarded a portion of the registered representative fees received from the National Association of Security Dealers to Archipelago.
[3.4]	To adjust the income tax provision for the effect of the pro forma adjustments based upon combined federal, state and local corporate income tax rates ranging from 35.0% to 41.0%

	depending on the companies involved in the respective business combinations. Deferred income tax impacts as a result of the purchase accounting adjustments were also estimated at a 35.0% to 41.0% blended income tax rate.
[3.5]	To adjust the weighted average shares to reflect the retirement of 1,645,415 shares of Archipelago common stock held by the Pacific Exchange at the time of acquisition.
[3.6]	To eliminate the merger costs incurred by the NYSE, Archipelago and Euronext as well as related Archipelago executive compensation and NYSE exit costs to arrive at pro forma income from continuing operations. The merger costs and related executive compensation and exit costs represent nonrecurring charges directly attributable to the business combinations.
[3.7]	To adjust the book value of Archipelago fixed assets and intangible assets to their estimated fair value. The preliminary allocations are as follows (in thousands):

	Increase in value			Estimated average remaining useful life	Estimated annual depreciation expense		Estimated half year depreciation expense
Fixed asset class:
Software	$	11,700		5 years	$	2,340	$	1,170

Intangible assets	$	584,500

Total	$	601,500			$	7,782	$	3,891

[a]: Prior to the completion of the PCX Holdings acquisition, the contractual right to operate ArcaEx as the exclusive equities trading facility of the Pacific Exchange and PCX Equities (and following the completion of the PCX Holdings acquisition, Archipelago's ownership of the Pacific Exchange and PCX Equities) allowed Archipelago to (i) generate revenues from market data fees (from equities and, following the completion of the PCX Holdings acquisition, options trading) and listing fees, and (ii) reduce its costs since clearing charges are not incurred for trades matched internally on ArcaEx. As a national securities exchange, NYSE Arca, Inc. is eligible to earn market data and listing fees and benefit from clearing cost savings.

INFORMATION ABOUT NYSE GROUP

Overview

NYSE Group is a holding company that, through its subsidiaries, operates and regulates two securities exchanges: the NYSE and NYSE Arca. NYSE Group is a leading provider of securities listing, trading and information products and services. NYSE Group was formed in connection with the merger of the NYSE and Archipelago, which was completed on March 7, 2006. Although the trading platforms of the NYSE and NYSE Arca currently operate separately, NYSE Group is actively integrating some of their activities to achieve revenue and cost synergies.

For the six months ended June 30, 2006, on a pro forma basis reflecting the merger of the NYSE and Archipelago, NYSE Group generated $898.6 million in revenues (excluding activity assessment fees) and $126.9 million in income from continuing operations.

The NYSE. The NYSE is the world's largest and most liquid cash equities exchange. The NYSE provides a reliable, orderly, liquid and efficient marketplace where investors meet directly to buy and sell listed companies' common stock and other securities. For 214 years, the NYSE has facilitated capital formation, serving a wide spectrum of participants, including individual and institutional investors, the trading community and listed companies. As of June 30, 2006, 2,697 issuers, which include operating companies, closed-end funds and ETFs, were listed on the NYSE, and the NYSE's listed operating companies represent a total worldwide market capitalization of over $22.6 trillion. For the period from January 2006 to June 30, 2006, on an average trading day, over 1.70 billion shares, valued at over $63.0 billion, were traded on the NYSE. The NYSE operates an auction market in which orders are electronically transmitted for execution. Specialists on the trading floor are charged with maintaining fair, orderly and continuous trading markets in specific stocks by bringing buyers and sellers together and, when circumstances warrant, adding liquidity by buying and selling stock for their own account. Floor brokers act as agents on the trading floor to facilitate primarily large or complicated orders. In this prospectus, this trading model is referred to as an "agency auction trading model."

NYSE Arca. NYSE Arca operates the first open, all-electronic stock exchange in the United States and has one of the leading market positions in the trading of exchange-listed securities and ETFs. NYSE Arca is also an exchange for trading equity options. Through NYSE Arca, customers can trade over 8,000 equity securities and over 175,000 option products. NYSE Arca's trading platforms link traders to multiple U.S. market centers and provide customers with fast electronic execution and open, direct and anonymous market access. The technological capabilities of NYSE Arca's trading systems, combined with its trading rules, have allowed NYSE Arca to create a large pool of liquidity that is available to customers internally on NYSE Arca and externally through other market centers. For the period from January 2006 to June 30, 2006, on an average trading day, over 640.4 million shares, valued at over $22.6 billion, are traded through NYSE Arca's trading platforms.

SIAC. NYSE Group also owns two-thirds of SIAC, and SIAC's financial results will be reported on a consolidated basis with NYSE Group's results. SIAC is an important industry resource providing critical automation and communications services to the NYSE, AMEX and other organizations to support order processing, trading and the reporting of market information, among other functions. SIAC also provides system support for certain national market system functions and for important regulatory and administrative activities. See "Risk Factors—Risks Related to NYSE Euronext's Business—NYSE Euronext's revenues from SIAC could significantly decrease if SIAC loses major customers" for a description of possible transactions with AMEX that might result in NYSE Group's 100% ownership of SIAC.

NYSE Regulation. NYSE Group also plays a critical role in the U.S. securities industry through its two SROs. As a not-for-profit company within NYSE Group, NYSE Regulation regulates the activities of member organizations through enforcement of SRO rules and federal securities laws. In addition, NYSE

203

Regulation oversees compliance by listed companies with NYSE Group's financial and corporate governance listing standards. See "Information About NYSE Group—NYSE Regulation" for a discussion of NYSE Group's regulatory business.

History

NYSE Group was organized under the laws of the state of Delaware in 2005 in connection with the combination of the NYSE and Archipelago.

NYSE. The NYSE operates a floor-based auction stock market, with a significant percentage of trades in a particular NYSE-listed stock taking place in a specific place on the floor through or under the supervision of a designated dealer known as a specialist. The specialist oversees trading and is required to maintain a fair and orderly market, acting as both a market maker and auctioneer. The NYSE also provides customers with electronic trading for NYSE-listed securities.

As demand for securities trading has increased, the NYSE has expanded its physical trading floor space, and as technology has become increasingly important in the U.S. securities industry, the NYSE has sought to develop technologies to increase choice and improve service to its customers, and to compete more effectively. In 1976, the NYSE introduced the Designated Order Turnaround® (DOT®) system to electronically route smaller orders directly to the specialist who acts as agent for these orders. Two years later, the NYSE and other exchanges jointly introduced the Intermarket Trading System to provide an electronic link between the NYSE and other exchanges. In 2001, in order to provide its customers with increased choice of execution methods, the NYSE fully launched NYSE Direct+®, which is a fully electronic execution trading platform. For the three month period ended June 30, 2006, approximately 16.6% of the NYSE's total share volume was executed automatically through NYSE Direct+®. The NYSE is also in the process of creating the NYSE Hybrid Market^SM, which is intended to combine the advantages of the agency auction trading model and those of automatic execution, offering the speed, certainty and anonymity of electronic trading as well as the opportunity for negotiation and price improvement provided by an auction.

NYSE Arca. In December 1996, Gerald D. Putnam, NYSE Group's president and co-chief operating officer, co-founded the Archipelago Electronic Communications Network, or the Archipelago ECN, the precursor to NYSE Arca LLC, by taking advantage of a market opportunity resulting from the SEC's new order handling rules governing securities trading. These rules were designed to address growing concerns regarding unfair and discriminatory pricing of customer orders for securities, and to promote transparency and enhance execution opportunities for customer orders in U.S. equity markets. See "Industry" for a discussion of industry rules and developments.

ECNs are electronic trading systems that automatically match buy and sell orders at specified prices, and are registered with the SEC as broker-dealers. The Archipelago ECN was the first ECN to link traders to pools of liquidity throughout the U.S. securities markets. In July 2000, Archipelago partnered with the Pacific Exchange to develop ArcaEx. The SEC approved the establishment of ArcaEx and the related rules in October 2001.

In March 2002, ArcaEx's listed platform became operational and Archipelago began trading Pacific Exchange-listed securities on ArcaEx. By November 2002, Archipelago completed the rollout of exchange-listed securities on ArcaEx, and in April 2003 Archipelago fully integrated its trading platforms and completed the migration of Nasdaq-listed securities from Archipelago ECN to ArcaEx.

On August 19, 2004, Archipelago completed an initial public offering of its common stock and on September 26, 2005, Archipelago acquired PCX Holdings, Inc. and all of its wholly owned subsidiaries, including the Pacific Exchange and PCX Equities.

204

Competitive Strengths

NYSE Group's principal competitive strengths include:

Leading Global Brand Name and Reputation. The "New York Stock Exchange" or "NYSE" is among the most well-recognized brand names in the world. For 214 years, the NYSE has facilitated national and global capital formation and symbolized the strength and vitality of the U.S. securities markets. Issuers that list with the NYSE benefit from association with this brand name.

World's Highest Overall Listing Standards. The NYSE has the highest overall listing and continued listing standards of any securities marketplace in the world. These listing standards improve the prestige and value of a NYSE listing. In the six month period ended June 30, 2006, the NYSE obtained approximately 89.7% of all domestic initial public offerings that qualified to list under the NYSE's standards, as measured by the aggregate proceeds raised by companies listing on U.S. exchanges. In addition, through NYSE Arca, NYSE Group provides a venue for issuers to list and trade securities that do not initially qualify to list under the NYSE's criteria. NYSE Group's listing venues provide issuers with unique benefits, including the affiliation with one of the world's leading brands, superior market quality based on measures such as liquidity and volatility, and a wide range of value-added products and services.

World's Largest Equities Market. NYSE Group operates the world's largest market for listing and trading cash equity securities and is one of the industry leaders for the trading of ETFs. In the first half of 2006, proceeds raised from initial public offerings of equity securities of U.S. domestic and non-U.S. companies and closed-end funds on the NYSE totaled approximately $13.9 billion, more than twice as much as any other U.S. market and more than the amount raised by domestic companies on any non-U.S. market. NYSE Group also operates the largest market for trading equity securities in the world and provides a highly liquid trading market for its listed stocks. As of June 30, 2006, the combined dollar value of transaction volumes of the NYSE and NYSE Arca represented approximately $11.2 trillion dollars, which was greater than the value of trading of Nasdaq ($5.2 trillion), the London Stock Exchange ($3.7 trillion), the Tokyo Stock Exchange ($3.2 trillion), Euronext ($2.1 trillion) and the Deutsche Börse ($1.4 trillion).

Broad Range of Products and Services. NYSE Group provides its customers with diverse platforms for the trading of listed and over-the-counter equities, ETFs, fixed income products and options products, as well as two listing venues for quality companies seeking access to the public markets. By operating multi-asset class markets that offer an expanded and enhanced range of products and services, NYSE Group believes that it is reinforcing its leadership position in the global securities market. Through the NYSE and NYSE Arca, NYSE Group offers multiple opportunities to trade cash equity securities, and NYSE Group believes that it provides deeper liquidity, lower volatility and execution costs and the best quoted prices. NYSE Group also believe the combined breadth of its product offerings will create new opportunities to offer its customers a broader array of market data products and services.

Strong and Effective Regulation. NYSE Group believes that its independent regulatory structure and high listing standards enhance its reputation and that of its listed companies and member organizations. NYSE Regulation, which operates as a not-for-profit entity, monitors and examines member organizations for, and enforces compliance with, federal securities laws and the rules of the NYSE and NYSE Arca. NYSE Regulation also oversees compliance by NYSE Group's listed companies with its financial and corporate governance listing standards. NYSE Group believes that its high original and continued listing requirements have helped NYSE Group maintain a strong brand name, which by association benefits its listed companies.

205

The NYSE and NYSE Arca

NYSE Group's business includes two market centers: (1) the NYSE and (2) NYSE Arca. The NYSE's business is operated mainly through two separate entities:

•: New York Stock Exchange LLC. New York Stock Exchange LLC is the entity registered as a national securities exchange. New York Stock Exchange LLC holds all of the equity interests of NYSE Market, NYSE Regulation and 66²/3% of SIAC. See "Risk Factors—Risks Relating to NYSE Euronext's Business—NYSE Euronext's revenues from SIAC could significantly decrease if SIAC loses major customers" for a description of possible transactions with AMEX that might result in New York Stock Exchange LLC owning 100% of SIAC.
•: NYSE Market, Inc. NYSE Market, Inc. is a wholly owned subsidiary of New York Stock Exchange LLC. NYSE Market conducts the market activities of the New York Stock Exchange.

NYSE Arca's business is operated mainly through three separate subsidiaries:

•: NYSE Arca, LLC and NYSE Arca Equities, Inc. NYSE Arca, LLC and NYSE Arca Equities operate an all electronic trading venue for equity securities listed with NYSE Arca, the NYSE, Nasdaq, AMEX, as well as for ETFs.
•: NYSE Arca, Inc. NYSE Arca, Inc. operates an exchange for trading equity options listed on national markets and exchanges including the facilities, technology, systems and regulatory surveillance and compliance services required for the operation of a marketplace for trading options.

The regulatory activities of the NYSE and NYSE Arca are conducted by NYSE Regulation, Inc. NYSE Regulation is a New York not-for-profit corporation whose sole equity member is New York Stock Exchange LLC. For a more detailed description of the activities of NYSE Regulation, see "Information About NYSE Group—NYSE Regulation."

The NYSE is the world's largest and most liquid cash equities market. For 214 years, the NYSE has facilitated capital formation by serving a wide spectrum of market participants, including individual and institutional investors, the trading community and listed companies. As of June 30, 2006, the NYSE listed approximately 2,697 issuers (which includes operating companies, closed-end funds and ETFs), many of which are the world's premier companies. For the period from January 2006 through June 30, 2006, on an average day, over 1.70 billion shares, valued at over $63 billion, were traded on the NYSE.

NYSE Arca LLC, formerly known as the Archipelago Exchange, or ArcaEx®, operates the first open, all-electronic stock market in the United States for trading equity securities listed on NYSE Arca, the NYSE, Nasdaq and AMEX, as well as ETFs and other exchange-listed securities. NYSE Arca is also an exchange for trading equity options, and operates the facilities, technology and systems required for the operation of marketplaces for trading equity securities and options. Through NYSE Arca, customers can trade over 8,000 equity securities and over 145,000 options series.

NYSE Arca's trading platforms link traders to multiple U.S. market centers and provide customers with fast electronic execution and open, direct and anonymous market access. The technological capabilities of NYSE Arca's trading systems combined with its trading rules have allowed NYSE Arca to create a large pool of liquidity that is available to customers internally on NYSE Arca and externally through other market centers. For the period from January 2006 through June 2006, on an average day, over 700 million securities, valued at over $20 billion, were traded through NYSE Arca's trading platforms.

Listings Business

As of June 30, 2006, approximately 2,697 issuers were listed on the NYSE. NYSE's listed operating companies represented a combined global market valuation of approximately $22.6 trillion as of that date. As of June 30, 2006, 28 of the 30 publicly traded companies that constitute the Dow Jones Industrial

206

Average and 85.0% of the stocks included in the S&P 500 Index were listed on the NYSE. As of June 30, 2006, the NYSE's roster of listed companies includes 450 non-U.S. companies from approximately 47 countries with a U.S.-publicly-held float of approximately $1.3 trillion and a total global market valuation of approximately $8.7 trillion.

As of June 30, 2006, there were approximately 167 issuers listed on NYSE Arca. 11 of these companies were exclusively listed on NYSE Arca and 165 were dually listed on the NYSE, AMEX or Nasdaq.

Fees are paid by companies when they initially list on the NYSE and NYSE Arca and annually thereafter. Listing fees, which are subject to a minimum and maximum amount, are based on the number of shares that a company lists with NYSE Group. Annual fees are charged on the outstanding shares of the company at the end of each year and are subject to a minimum and maximum fee. Listed companies also pay fees in connection with corporate transactions involving the issuance of new shares, such as stock splits, rights issues, sales of additional securities and mergers and acquisitions. Non-U.S. companies pay fees based on the number of listed securities issued or held in the United States.

NYSE Group is in the unique position of offering its customers the option of using either floor-based auction trading or electronic trading through NYSE Direct+® for NYSE-listed stocks, which is being further enhanced through the rollout of NYSE Hybrid Market^SM. NYSE-listed stocks show consistently lower volatility and execution costs than comparable stocks listed on other venues. For example, based on a recent study of 67 NYSE-listed companies that transferred from Nasdaq between 2002-2005, the average intraday volatility for these companies was reduced by 48% following their transfer from Nasdaq, while average execution costs were reduced by 38%. These results are attributable to both the extraordinary natural liquidity that resides at the NYSE and the role of the NYSE specialists, who have an affirmative obligation to cushion price movement and reduce volatility.

The NYSE generally produces the best quoted prices in NYSE-listed stocks and warrants, and offered the national best bid and offer 84.1% of the time for the first half of 2006. During the same time period, NYSE Arca set the national best bid and offer 7.2% of the time in NYSE-listed securities. On a combined basis, the market centers of the NYSE Group provided the best quoted prices in NYSE-listed stocks and warrants 91.3% of the time during the first half of 2006.

Through NYSE Arca, customers can trade equity securities, ETFs and other derivative products in an all-electronic environment. NYSE Arca also provides customers with a venue for trading equity options listed on exchanges. NYSE Arca's core trading technology platform is highly reliable, efficient, and scalable, and NYSE Group is actively developing applications to leverage this technology for use in other asset classes including options and fixed income. NYSE Arca's industry leading system is designed to accept up to 18,000 orders per second and to provide up to 1,000 simultaneous customer connections. During the first half of 2006, the system handled an average of 48.2 million orders daily and 2.7 million trades daily, with a capacity to handle 20 million trades daily. NYSE Arca's electronic systems also provide customers with broad capabilities, including diverse order types and other functionality to meet customers' needs for speed and immediacy.

New Listings

NYSE Group relies on new listings to maintain its competitive position in the United States and global markets. From January 1, 2001 to June 30, 2006, 604 domestic companies listed on the NYSE. This included 179 closed-end funds, 138 transfers from other markets, 49 spin-offs and 238 initial public offerings of operating companies. Among the initial public offerings of securities qualified to be listed on the NYSE from January 1, 2001 to June 30, 2006, the capital raised by those in fact listing on the NYSE represented 88.4% of the aggregate proceeds raised in all those qualified offerings. From January 1, 2001 to June 30, 2006, 93 companies have transferred their listing from Nasdaq to the NYSE. During that same period, only four companies voluntarily transferred from the NYSE to Nasdaq. Two additional companies

207

elected to transfer to Nasdaq in advance of SEC approval of recent amendments made to NYSE's continued listing standards that would have resulted in such companies being deemed below compliance.

In addition, since March 8, 2006, two new operating companies listed on NYSE Arca, one in conjunction with its initial public offering and one as a transfer from Nasdaq.

A key to the NYSE's past success and future growth is its ability to list and retain non-U.S. companies. Generally, international companies are attracted to the U.S. and the NYSE to take advantage of the deep and diverse investor base, to signal that they meet the world's most stringent overall listing standards and to take their place alongside other global leaders. From January 1, 2001 to June 30, 2006, 151 international companies have listed on the NYSE.

The NYSE actively pursues new closed-end fund listings. From January 1, 2001 to June 30, 2006, 179 closed-end funds have listed on the NYSE, raising over $80.7 billion in proceeds in their initial public offerings. This represents 75.2% of the funds qualified to list and 80.6% of the total closed-end fund qualified proceeds. As of June 30, 2006, the NYSE lists 479 closed-end funds, up from 394 on January 1, 2001.

Since 1988, the NYSE has supported the capital raising needs of companies qualified to list on the NYSE by providing a market for both debt and equity structured products—such as capital securities, mandatory convertibles, repackaged securities and equity-linked index-linked securities—and for debt securities traded on the trading floor. The number of new issuances and redemptions of these securities in any given year depends on many external factors, including interest rate levels and changes, economic conditions and financial regulation. As of June 30, 2006, the NYSE's structured products group listed approximately 600 securities.

NYSE Group is also at the forefront of growth in listing and trading Exchange Traded Funds (ETFs). ETFs are open-end investment products listed and traded in the secondary marketplace by a broad range of investors. The ETF marketplace now has 298 listings in the United States, of which the NYSE has 100 listings as of June 30, 2006. On July 20, 2005, Barclays Global Investors, the largest issuer of ETFs, announced its intention to transfer up to 61 listings to the NYSE and 20 listings to NYSE Arca from AMEX over the course of 2005-2007. As of June 30, 2006, 40 of these ETFs have transferred to the NYSE.

Listing Standards

The NYSE and NYSE Arca requires that companies seeking to list securities meet minimum financial, distribution and corporate governance criteria. While in recent years the corporate governance criteria imposed by the various U.S. markets have become substantially similar, the NYSE's overall listing standards have traditionally been, and continue to be, the most stringent of any securities marketplace in the world. Once listed, companies must meet continued listing standards. All standards are periodically reviewed to ensure that the NYSE attracts and retains the strongest companies with sustainable business models.

NYSE Group plans to leverage the NYSE brand to continue to build NYSE Arca's listing business. NYSE Group expects NYSE Arca's pending listing standards will extend the NYSE's current focus on quality companies to growing companies that initially do not meet the NYSE's stringent listing standards. NYSE Arca's listing venue will provide issuers with many of the benefits that are provided to NYSE-listed companies, including an affiliation with one of the world's leading brands, exceptional market quality and a wide range of value added products and services. By leveraging the NYSE brand across two listings platforms, NYSE Group believes it will be better positioned to serve a broader segment of corporate issuers.

Each year, a number of companies cease to be listed on the NYSE, mostly as a result of normal corporate actions, such as mergers and acquisitions. From January 1, 2001 to December 31, 2005, approximately 27% of the 783 delistings from the NYSE resulted from the failure by the delisted company

208

to comply with the NYSE's quantitative and/or qualitative continued listing standards. Over this period, new listings on the NYSE have kept the NYSE's overall number of listed companies at a relatively constant level.

Client Service

NYSE Group has a team of professionals dedicated to serving the needs of its listed company community. These "client service managers" meet with their assigned listed companies individually and in regional executive forums that are scheduled by NYSE Group. They provide value by keeping issuers aware of market trends, market structure initiatives and developments in governance and regulation. NYSE Group believes that executives of listed companies place a high value on their relationship with their client service manager and on superior market quality, association with leading brands, global visibility, and unique marketing services that NYSE Group provides. Client retention is consistently very high (i.e., greater than 99.9%).

NYSE Group offers a variety of services to its listed companies, including the ability to leverage the NYSE brand in reaching out to existing and prospective investors. It sponsors virtual forums, as well as domestic and international conferences, to provide issuers access to global institutional and retail investors. NYSEnet, a password-protected website for senior executives, provides data relating to proprietary trading, institutional ownership-and market activity. The NYSE has also developed eGovDirect.com^SM for use by listed companies, which is an interactive, web-based tool that helps listed companies meet their NYSE governance and compliance requirements efficiently and economically; as of June 30, 2006, approximately 1,318 NYSE-listed companies were registered for access to this site. In addition, NYSE Group believes that its executive education programs and the opportunities they offer to network with policy makers and fellow corporate executives are highly valued by the leaders of NYSE- and NYSE Arca-listed companies. Moreover, NYSE Group uses a range of advertising media, including print and radio, among others, to promote its listed companies through a variety of ongoing campaigns.

Options Business

Through NYSE Arca, Inc., NYSE Arca operates a marketplace for trading options on exchange-listed securities. The underlying securities are listed and trade on NYSE Arca, the NYSE, AMEX and Nasdaq.

NYSE Arca's option market center includes the trading facilities, technology and systems for trading options as well as regulatory, surveillance and compliance services. It also provides listing services for options on stocks that meet certain minimum criteria. NYSE Arca's options business trades approximately 500,000 contracts each day on more than 1,700 stocks.

NYSE Arca's options business uses a technology platform and market structure that is designed to enhance the speed and quality of trade execution for its customers and to attract additional sources of liquidity by allowing market makers to have access to its markets remotely and by integrating floor-based participants and remote market makers. On July 28, 2006, NYSE Arca, Inc. received SEC approval to operate a new platform for options trading with technology based on the architecture of its equities trading platform. NYSE Arca launched this platform on August 7, 2006, and intends to complete the rollout of options to the new trading platform by the end of October 2006. The revenue from NYSE Arca's options business is primarily derived from transaction execution services and market data services in a real-time or summary basis.

NYSE Group refers to permitted users of NYSE Arca, Inc.'s options trading system as "options trading permit holders." Any qualified broker-dealer who wishes to trade on NYSE Arca, Inc.'s options trading system may obtain an options trading permit from NYSE Arca, Inc.

Options Listing. Under the rules of NYSE Arca, Inc. in order to list an option on a stock, there must be at least seven million shares of the underlying stock available for public trading, with at least 2,000

209

holders of the security. In addition, there must be active public trading in the underlying stock, and that stock must meet certain minimum price tests. These rules also include specialized criteria for listing options on certain types of securities, such as shares of index funds or exchange-traded funds, trust-issued receipts and American Depositary Receipts. Compliance with these rules and criteria are monitored and determined by NYSE Arca, Inc.

Options Products. Options contracts are contracts with standardized terms that give the buyer the right, but not the obligation, to buy or sell a particular stock or stock index at a fixed price (the strike price) for a specified period of time (until the expiration date). Options are used in various ways by a range of investors with different goals and strategies, such as protecting equities portfolios by using options as a hedge and buying puts as a protection against unexpected declines in price, or speculating on the direction of a stock price by purchasing puts or calls in anticipation of a stock's directional movement and hope of return on risk.

Options Clearing and Settlement. All options contracts traded on NYSE Arca's options exchange as well as other U.S. securities exchanges are issued and cleared by The Options Clearing Corporation (referred to in this prospectus as the OCC), a clearing corporation registered with the SEC and owned by member options exchanges, including NYSE Arca, Inc. The OCC, which issues and clears all U.S-listed options, as well as certain futures and options on futures on a number of underlying financial assets, including common stocks, currencies, stock indices and interest rate composites, is among the world's largest clearing organizations for options and equity derivatives.

Options Transaction Fees. In conjunction with the rollout of the new options platform, NYSE Arca introduced a new pricing schedule that provides greater cost efficiencies for options investors. Effective August 1, 2006, transaction fees for Market Makers were reduced from $0.26 per contract to $0.16 per contract; transaction fees for Lead Market Makers were reduced from $0.26 per contract to $0.09 per contract; and transaction fees for Electronic Broker Dealer transactions were reduced from a combined total of $0.51 to $0.50 per contract. One Options Trading Permit (OTP) for Market Makers is $4,000 per month per OTP. Each OTP entitles market makers to quote in an expanded number of products of their choosing. Four Market Maker OTP permits, totaling $16,000, allows trading in all exchange products. OTP firms acting as Lead Market Makers are assessed a fee for LMM Rights on a per issue basis in addition to the OTP Trade Participant Rights. LMMs Rights per issue range from $150 to $3,000 per month. OTP Rights for order entry firms increased from $750 to $1,000 per month. OTP Rights for Floor Brokers dropped from $1,500 to $1,000 per month. The Cancellation fee was phased out with the introduction of the new trading platform. All application and surcharge fees were eliminated.

Order Execution Business

One of NYSE Group's primary functions is to ensure that orders to purchase and sell securities are conducted in a reliable, orderly, liquid and efficient manner. Order execution occurs through a variety of means, and NYSE Group seeks to continue to develop additional and more efficient mechanisms of trade.

Auction Market. One of the primary means for order execution is through the NYSE's auction market, in which orders are electronically transmitted for execution. Specialists at various locations on the trading floor are charged with maintaining fair, orderly and continuous trading markets by bringing buyers and sellers together and, in the relative absence of orders to buy or sell their assigned stock, adding liquidity by buying and selling the assigned stock for their own accounts. Floor brokers act as agents on the trading floor to handle customer orders.

Effective August 1, 2006, the NYSE implemented a simplified transaction fee structure for equities traded on the NYSE that made fees more transparent and distributed costs more equitably across our customer base. Transaction fees on NYSE-listed equities traded on the NYSE are based on a fixed rate of $0.00025 per share, with a monthly cap of $750,000. The long-standing 2% commission cap for NYSE-

210

listed trading on the NYSE was eliminated. Free system orders on all NYSE-listed equities transactions were also eliminated. NYSE Arca transaction pricing for NYSE-listed securities remained unchanged. NYSE Group continues to examine its transaction pricing as part of an ongoing strategic review of opportunities for revenue growth and efficiency improvement, and to better align transaction revenue with executed volume, product expansion and new product development.

Electronic Trading. Order execution also occurs through the NYSE's electronic trading platform, NYSE Direct+®, which represented approximately 16.6% of the NYSE's total share volume for the three month period ended June 30, 2006. NYSE Direct+® is an automatic-execution service for non-ETF limit orders of up to 1,099 shares for all securities other than Phase III pilot securities, for which the limit is 1,000,000 shares (with a maximum supported order size of 3,000,000 shares for ETFs and similar securities) and enables users to elect immediate execution at the best bid or offer, without a fee and with anonymity and speed.

NYSE Arca operates two all-electronic equity securities trading systems, one for trading NYSE-, AMEX- and other exchange-listed securities, and another for trading Nasdaq-listed equity securities. These trading systems offer a variety of execution-related services, including NYSE Arca's "best execution routing" capability and routing services through the NYSE's DOT® system. NYSE Arca's systems operate on three simple but fundamental principles: fast electronic execution, transparency, and open market access. On NYSE Arca, buyers and sellers meet directly in an electronic environment governed by trading rules designed to reflect these three fundamental principles.

The rules governing trading on NYSE Arca require execution of orders, without discretion, in accordance with the principles of openness, fairness and equal access. These trading rules are predicated on "price-time priority" within NYSE Arca, which requires execution of orders at the best available price and, if orders are posted at the same price, based on the time the order is entered on the trading system. NYSE Arca's electronic matching and routing systems actively search across multiple market centers and either match orders internally or route orders out to the best bid or offer displayed in the market using NYSE Arca's "best execution routing" capability. The technological capabilities of NYSE Arca's trading systems, together with its trading rules, have allowed NYSE Arca to create a large pool of liquidity available to its customers internally on NYSE Arca or externally through other markets.

On NYSE Arca, buyers and sellers can view the NYSE Arca open limit order book, which displays orders simultaneously to both the buyer and the seller. Buyers and sellers can submit these orders on an anonymous basis if they so choose. Once orders are submitted, all trades are executed in the manner designated by the party entering the order, which is often at prices equal to or better than the national best bid or offer. The national best bid or offer is the highest bid or lowest offer quote reported to the Consolidated Quote and Nasdaq pursuant to the quotation and transactions reporting plans. See "Industry." Buy orders and sell orders are posted on NYSE Arca in price order (best to worst) and then if prices are the same, they are ordered based on the time the buy order or sell order was posted (earliest to latest). NYSE Arca users may choose to have their unexecuted orders left on NYSE Arca's open order book, returned to them, or routed to other markets using NYSE Arca's "best execution routing" capability.

NYSE Group refers to permitted users of NYSE Arca's equity trading systems as "equity trading permit holders." Any qualified broker-dealer who wishes to trade on NYSE Arca's equity trading systems may obtain an equity trading permit from NYSE Arca.

For equity securities, NYSE Arca charges a per share fee (denominated in tenths of a cent per share) to each customer that executed against a buy order or sell order posted internally on the NYSE Arca system. NYSE Arca refers to these customers when they purchase or sell securities as "liquidity takers," as they removed liquidity from the NYSE Arca system. A liquidity taker may be either a purchaser or a seller, and is distinguished from a "liquidity provider" generally by the type of buy order or sell order it posts on NYSE Arca's system. A liquidity provider will likely enter a non-marketable limit order on the NYSE Arca system (i.e., either a limit order to buy a security with a limit price below the best offer or a limit order to

211

sell a security with a limit price above the best bid). Non-marketable limit orders are placed on the NYSE Arca limit order book and await execution. A liquidity taker, on the other hand, is likely to enter a marketable limit order (i.e., a limit order to buy a security with a limit price at or above the best offer or a limit order to sell a security with a limit price at or below the best bid for that security). Accordingly, liquidity providers generally "post" buy orders or sell orders that are subsequently executed against by the sell order or buy order, as the case may be, of a customer that is the liquidity taker. As discussed below, NYSE Arca pays liquidity providers a per share fee for posting buy orders and sell orders on NYSE Arca's system.

NYSE Arca also charges a per share fee (denominated in tenths of a cent per share) to customers whose orders of equity securities were routed out to an external market center displaying the best buy order or sell order in the market for a particular security.

Effective October 1, 2006, subject to SEC approval, NYSE Arca will change its rates for trading NYSE-listed securities as follows: (i) the rate for removing liquidity from NYSE Arca will increase from $0.001 per share to $0.003 per share; and (ii) NYSE Arca will rebate $0.002 per share for the provision of liquidity, a change from its current fee schedule which neither charges for nor offers a rebate for the provision of liquidity to NYSE Arca.

MatchPoint Trading. On July 17, 2006, NYSE Group acquired MatchPoint Trading, Inc., a financial services technology company specializing in call market trading and technologies. MatchPoint has developed a proprietary electronic equity crossing system that matches aggregated orders at predetermined and distinct times, at prices that are derived from the primary market for securities (NYSE, AMEX and NASDAQ), enabling MatchPoint technology to operate multiple matches each with a unique benchmark pricing model. MatchPoint can also process internal crosses for single participants and seamlessly enables residuals to participate in scheduled crossing sessions. It is anticipated that MatchPoint's expansive and innovative trading technology will enhance the suite of crossing services provided by the NYSE in the first quarter of 2007.

Marco Polo Network Inc.

On September 18, 2006 NYSE Group announced that it had acquired an equity stake in Marco Polo Network Inc. Through its local exchange and brokerage relationships, Marco Polo Network offers intra-market connectivity and routing to brokers and exchanges in more than 40 emerging markets. Together, these markets provide investors with access to more than 90% of the MSCI emerging markets index.

Fixed Income Business

The NYSE also operates the largest centralized bond market of any U.S. exchange or other self-regulatory organization. A broad selection of bonds is traded on the NYSE, such as corporate (including convertibles), agency and government bonds. The trading volume of bonds on the NYSE is primarily in corporate bonds, with approximately 94% of this volume in non-convertible bonds. Bonds trade on the NYSE through the NYSE's ABS®, a screen-based system used by NYSE member organization subscribers, which was implemented in 1977. ABS® maintains and displays priced bond orders and matches those orders on a strict price and time-priority basis. It also reports real-time quotes and trades to market data vendors. The NYSE is actively developing applications to leverage NYSE Arca's core technology to upgrade its current bond trading platform.

Indices & Index Services

Index Calculation Services. NYSE Arca offers an index calculation service for investment ideas that ultimately serves as the reference indicator for exchange-traded funds and other structured products. Custom index calculation is an important component to the development of traded products on the exchange, and allows the exchange to leverage its technology and understanding of traded products to

212

better serve investors. Additionally, NYSE Arca provides various intra-day ETF fund valuation services to the ETF issuers and trading community. All of the Index Services are designed to offer our clients more tools and services to support the listing and trading.

NYSE Group Indices. NYSE Group has created six benchmark indices. The NYSE established its first index, the NYSE Composite Index, in 1966 to provide a comprehensive measure of the performance of all of the common stocks listed on the NYSE. Four other NYSE-branded indices were launched in June 2002, all of which are composed entirely of NYSE-listed companies. The March 2006 merger with Archipelago expanded the existing offerings with the addition of the NYSE Arca Tech 100 Index. The NYSE has licensed the NYSE Composite Index and the NYSE U.S. 100 Index to Barclays Global Investors, N.A. for use in replicating the performance of the indices in the iShares NYSE Composite Index Fund and the iShares NYSE U.S. 100 Index Fund.

The NYSE Composite Index is designed to measure the performance of all common stocks listed on the NYSE, including REITs, tracking stocks and common equity and ADR listings of foreign companies. The NYSE Composite consists of over 2,000 U.S. and non-U.S. stocks. The index utilizes a transparent, rule-based methodology which includes free-float market cap weighting. The total float- adjusted market capitalization as of July 31, 2006 was more than $18 trillion. All companies in the NYSE Composite have to meet the initial listing standards of the NYSE, providing a base level of quality for the index's potential components. In addition to serving as a broad-based benchmark, the NYSE Composite establishes a universe from which other NYSE-branded indices are derived.

The NYSE U.S. 100 Index is designed to measure the performance of the largest 100 U.S. stocks listed on the NYSE. The index had a total market capitalization as of July 31, 2006 of over $6.7 trillion. The component companies of this index, ranked by market capitalization, are major market participants, most of which are well known household names.

The NYSE International 100 Index is designed to measure the performance of the largest 100 non-U.S. stocks listed on the NYSE. All 100 components are ADRs from 18 different countries that trade on the NYSE. The index had a total market capitalization as of July 31, 2006 of over $5.0 trillion.

The NYSE World Leaders Index consists of components from the NYSE U.S. 100 and the International 100 indices. It tracks the performance of 200 leading companies across 19 countries. The index had a total market capitalization as of July 31, 2006 of approximately $12.0 trillion.

The NYSE TMT index measures the performance of the largest 100 NYSE-listed U.S. and non-U.S. stocks in three sectors: Technology, Media and Telecommunications (TMT). The index had a total market capitalization as of July 31, 2006 of approximately $2.0 trillion.

The NYSE Arca Tech 100 Index (formerly the ArcaEx Tech 100 Index) is a price weighted, broad based index of 100 securities, established in 1982. Modeled as a multi-industry technology index, the objective of the NYSE Arca Tech 100 Index is to provide a benchmark for measuring the performance of companies using technology innovation across a broad spectrum of industries: computer hardware, software, semiconductors, telecommunications, data storage and processing, electronics and biotechnology, to name just a few. NYSE Arca Tech 100 Index is a tech sector equivalent to the Dow Jones Industrial Average and is a market indicator used by mutual fund rating services, analysts, asset managers and private investors to gauge the overall performance of the technology sector of the U.S. equity market. On July 28, 2006 the Exchange Traded Trust filed a registration statement to create an ETF replicating the performance of the NYSE Arca Tech 100 Index.

Market Data Business

NYSE Group collects and distributes market data, including real-time information relating to securities quotations, limit orders and the prices at which securities transactions take place. The broad distribution of accurate and reliable real-time market data is essential to the proper functioning of any

213

securities market because it enables market professionals and investors to make trading decisions. NYSE Group believes that the quality of its market data, and the ability of traders to act on that data, attract order flow to the NYSE and NYSE Arca for execution and reinforce the NYSE brand. The pricing for market data products must be approved by the SEC on the basis of whether prices are fair, reasonable and not unreasonably discriminatory. For a discussion of recent regulatory changes affecting market data, see "Regulation—U.S. Regulation—Recent U.S. Regulatory Developments."

NYSE Group's market data activity is divided into two parts: consolidated data services and proprietary data products.

Consolidated Data Services

The SEC requires securities markets to consolidate their bids, offers and last sale prices for each security, and provide the public with an integrated source of this information. NYSE Group works with other markets to make this market data available on a consolidated basis on what is often referred to as the "consolidated tape." This intermarket cooperative effort provides the investing public with the reported transaction prices and the best bid and offer for each security, regardless of the market to which a quote or trade is reported or on which a trade takes place.

Last sale prices and quotes in NYSE-listed securities are disseminated through Tape A, which constitutes the majority of the NYSE's revenues from consortium-based market data revenues. NYSE Group also receives a share of the revenues from Tape B and Tape C, which represents data related to trading of certain securities that are listed on Nasdaq, AMEX, and other regional exchanges, including ETFs.

Proprietary Data Products

NYSE Group makes certain market data available independently of other markets. The NYSE packages this market data as:

•: trading products (such as NYSE OpenBook®, through which the NYSE makes available all limit orders); and
•: analytic products (such as TAQ Data, NYSE Broker Volume® and a variety of other databases that are made available other than in real-time and that are generally used by analytic traders, researchers and academics).

These products are proprietary to NYSE Group, and NYSE Group does not share the revenues that it generates from these products with other markets. The pricing for proprietary products must be approved by the SEC.

Over the past two decades, NYSE Group has expanded its market data business by tapping new markets, in particular nonprofessional subscribers, the cable television audience and customers interested in NYSE Group's proprietary data products. Revenues for NYSE Group proprietary data products have grown significantly over the last few years, fueled in large part by the success of NYSE OpenBook®, which the NYSE introduced in 2002. The advent of trading in penny increments and the accelerated use of "black box" trading tools accelerated the success of NYSE OpenBook®.

NYSE Arca also makes certain market data available independent of other markets, including the following products:

•: ArcaVision®. ArcaVision® offers analytic tools that go beyond the traditional trading data that is available to customers. NYSE Arca developed ArcaVision® in response to customer demand for increasingly detailed analyses of trading patterns, and it is designed to provide customers with critical market data on particular stocks. The ArcaVision® website is available to issuers listed on NYSE Arca, customers executing trades on NYSE Arca, and the general public. ArcaVision®'s

214

sophisticated system enables NYSE Arca to customize the views available to each user to meet their specific needs.

•: ArcaBook®. ArcaBook® displays the limit order book of securities traded on the NYSE Arca trading platform in real time. Pending SEC approval, NYSE Arca intends to begin charging a fee to access ArcaBook®. NYSE Group is unable to predict what impact this may have on its revenues.

NYSE Trading Floor

The NYSE operates approximately 46,000 square feet of contiguous trading floor space where specialists, floor brokers and clerks engage in the purchase and sale of securities. As of June 30, 2006, there were 418 specialists, 843 floor brokers and 2,267 clerks conducting business on the NYSE's trading floor. The NYSE derives revenues from these specialists, brokers and clerks by providing them with various products and services, including space, necessary for them to engage in the purchase and sale of securities on the trading floor.

The NYSE Hybrid Market^SM Initiative

On March 22, 2006, the SEC approved the NYSE Hybrid Market^SM, which combines auction-based and electronic trading for equities listed on the NYSE. This initiative is NYSE Group's response to the request from both market professionals and individual investors for greater choice and flexibility in buying and selling stocks on the NYSE. The NYSE Hybrid Market^SM is also NYSE Group's strategy for adapting to the revised "trade through" rule adopted by the SEC on April 6, 2005 as a part of Regulation NMS, which prohibits trading-through of quotations that are displayed by another market and immediately accessible through automatic execution.

The NYSE Hybrid Market^SM is intended to emulate, in a primarily automatic-execution environment, the features of the traditional auction market that have provided stable, liquid and less volatile markets, as well as the opportunity for price improvement. The NYSE Hybrid Market^SM will expand the availability of the NYSE's current automatic execution service (NYSE Direct+®), which provides order execution at sub-second speed and, for the three month period ended June 30, 2006 handled approximately 16.6% of the NYSE's average daily share volume. The NYSE Hybrid Market^SM is intended to feature the following:

•: All quotes will be automatically and continuously refreshed and reflect the combined liquidity of the NYSE Display Book® and the electronic interest of trading floor broker agents and the specialist. Limit orders will be published in real time. This structure will facilitate the ability of brokers and specialists to interact with supply and demand and to scale interest and provide price improvement to incoming electronic orders seeking liquidity.
•: Customers will have the choice of auction representation and the opportunity for price improvement over the published best bid and offer. The NYSE's auction model currently provides price improvement for more than 25% of incoming orders, most obtaining improvement better than the midpoint of the quote spread.
•: Specialists and floor brokers will supplement liquidity to stabilize price movements in both the automated and auction components of the NYSE Hybrid Market^SM through the use of floor broker agency interest files, and specialist layered interest files and specialist algorithmic interaction with orders. As such, both electronically and manually executed orders may benefit from the value added by specialists in committing capital and providing depth to the market, and from the competition among electronic orders as well as those represented by floor brokers. Floor brokers will participate both electronically and in person, using human judgment to process large or complex orders more effectively than would otherwise be possible on a solely electronic platform.
•: Time restrictions between the entry of orders by the same beneficial owner on NYSE Direct+® will be eliminated and all size limit and market orders will be accepted up to the maximum supported

215

order size, which is currently 1,099 shares for most equity securities, 3,000,000 shares for ETFs and 1,000,000 for equity securities included in Phase III of the NYSE Hybrid Market^SM rollout.

•: Those customers that desire sub-second, automatic trade execution will have access to floor liquidity. Customers with buy and sell orders beyond the size of the best bid or offer will have the ability to "sweep the book" or designate individual orders to trade at multiple price points subject to certain limitations, including the Liquidity Replenishment Points^SM or "LRPs" described below.
•: In order to preserve the lower volatility that has characterized trading on the NYSE, pre-determined and published LRPs^SM will limit severe price moves. When activated, LRPs will allow integration of the electronic market with the auction market for one transaction, thus enabling the specialist to elicit additional trading interest.
•: All better-priced top-of-book bids and offers entitled to protection under Regulation NMS in all other automated markets will be immediately accessed unless customers are provided the same price on the NYSE. All incoming orders from all competing market centers will be automatically executed at the displayed best price. This will create an environment in which best prices will be protected from inferior-priced trade executions regardless of where an order is entered, and without awaiting human reaction.
•: As part of the NYSE Hybrid Market^SM initiative, the NYSE will further automate routine specialist tasks and create a new interface to facilitate algorithmic liquidity injection by specialists. In addition, the NYSE will add new functionality to trading floor broker wireless hand-held computers to further automate smart order types and create a new broker interest file with layering capabilities.

The NYSE Hybrid Market^SM will build on the NYSE's core attributes of liquidity, pricing efficiency, low trading costs and tight spreads by broadening customers' ability to trade quickly and anonymously. The NYSE Hybrid Market^SM will also further the NYSE's goal of providing all investors, regardless of their size, with the best price when buying or selling shares. Interaction of the NYSE's automatic and auction markets also would maintain the opportunity for price improvement.

By continuing to maintain market quality, including lower intra-day volatility, the NYSE Hybrid Market^SM will also allow issuers to reduce their cost of capital. Combining the NYSE's technology with the advantages of the auction market would enable the NYSE market to function more effectively and efficiently. In the NYSE Hybrid Market^SM, specialists and brokers, who will use judgment to improve prices and enhance order competition on the floor of the NYSE, will interact with the market electronically as well as manually. NYSE Group believes that their judgment will be particularly valuable in less liquid stocks and during the opening and closing of trading, as well as during times of uncertainty, for example, when a corporate announcement or an outside event could lead to market instability and price volatility.

The NYSE is developing the software that will power the NYSE Hybrid Market^SM. In December 2005, the NYSE initiated the first phase of the NYSE Hybrid Market^SM as a pilot to test selected features and functionality among a limited number of securities approved by the SEC. The pilot terminated upon SEC approval of the NYSE Hybrid Market^SM initiative and floor-wide roll-out of the first phase began. As of April 5, 2006, the first phase of the NYSE Hybrid Market^SM was implemented in substantially all securities listed on the NYSE. To date, NYSE Hybrid Market^SM software is functioning as expected, and all features are being actively exercised by trading floor professionals. The NYSE has completed its rollout of Phase II software and specialist firms are in various stages of testing and implementing their software. All specialist firms across all applicable securities are expected to be live by October 2006. In addition, the NYSE filed and received approval from the SEC to conduct a Phase III pilot in Lucent Technologies Inc. to provide full automated execution capabilities as provided in Phase III. The pilot has been live since May 12, 2006 and has worked as expected.

NYSE Membership Organizations

NYSE member organizations are comprised of (i) entities who obtain trading licenses in accordance with the rules and regulations of the NYSE (including the rules of eligibility that will apply to those who wish to be a member organization); and (ii) broker-dealers who agree to submit to the jurisdiction and regulations of the NYSE without obtaining a trading license. As member organizations, they are subject to the rules and policies of the NYSE. In the future, NYSE Group may decide to offer member status to other types of organizations; for example, if NYSE Group decides to issue separate licenses for electronic access or access for particular products.

NYSE Trading Licenses

Physical and electronic access to the trading facilities of the NYSE, subject to such limitations and requirements as may be specified in the rules of the NYSE, are available only to member organizations that have purchased a trading license from NYSE. These trading licenses have the following attributes:

•: Duration and Pricing. The price of trading licenses is determined through a modified Dutch auction process once per year. The NYSE will sell trading licenses at the lowest bid price in the auction that will allow for the sale of at least 1,000 trading licenses, as long as such bid price is at least equal to 80% of the previous year's trading license price. The clearing price at which all licenses are sold in the auction is determined under procedures calculated to provide suitable revenue to NYSE Market while providing fair access to its facilities to member organizations that wish to do business there. On January 4, 2006, based on this modified Dutch auction process, the NYSE sold 1,274 trading licenses at an annual price of $49,290 per license, subject to SEC approval of applicable NYSE rules, which approval was obtained on February 27, 2006. The NYSE has made a total of 1,366 trading licenses available for purchase during 2006, the remainder of which can be purchased, subject to the approval of NYSE Regulation, for a premium of 10% to the auction price. Except for these initial trading licenses, which will be valid from March 7, 2006 through the end of 2006, each trading license will be valid for one calendar year.
•: Availability. NYSE Group expects that the number of trading licenses that will be outstanding (as well as the price for these licenses) will be determined through an auction process on an annual basis. NYSE Group also has the right to sell additional trading licenses during the year at a price greater than the auction price, in order to, among other things, ensure that the supply of trading licenses is adequate to meet demand for the trading licenses should conditions change after the auction and to accommodate new businesses that commence operations after the beginning of the year. Holders of trading licenses have the right to cancel their trading license prior to the end of the year, subject to paying NYSE Market an early termination penalty. A maximum of 1,366 trading licenses can be outstanding at any time during the year.
•: Approval of NYSE Regulation. Any bidder for a trading license is subject to the approval of NYSE Regulation.

NYSE Group has not determined whether it will issue separate licenses for access for particular products.

Securities Industry Automation Corporation (SIAC)

Overview

SIAC is the principal vendor of the NYSE Group's data processing and software development services and a registered securities information processor under the Exchange Act. NYSE Group owns two-thirds

217

of the equity of SIAC, and AMEX owns the remaining one-third. Formed in 1972 as a New York business corporation, SIAC:

•: plans, develops, implements and operates a variety of automated information-handling and communication systems that support order processing, trading, and market data reporting, as well as trade comparison, for a broad range of securities;
•: provides systems support for essential regulatory and administrative activities; and
•: operates and manages the SFTI^SM network, which provides resilient and reliable communications within the financial services industry.

Historically, SIAC has been operated as a cost-recovery utility. As a result, it provides its services to its customers on an at-cost, non-profit basis. SIAC's contribution to NYSE revenues, excluding activity assessment fees, accounted for 10.3% of the NYSE Group's total revenue for the six months ended June 30, 2006.

SIAC's wholly owned for-profit subsidiary, Sector, Inc., offers an array of communications and data processing services, primarily to the broker-dealer community. These services include email archiving, other books and record storage solutions, facilities management, data center hosting, disaster recovery, enterprise services and network and data distribution services. The telecommunications services include traditional point-to-point voice circuits and network management. Sector is headquartered in New York City.

SIAC Governance

The SIAC bylaws provide that the SIAC board of directors shall consist of 14 directors. Under a shareholders' agreement among SIAC, the NYSE and AMEX, of these 14 directors:

•: seven directors are selected by the NYSE (provided that at least five of these seven directors are not officers or employees of the NYSE unless they are also members of New York Stock Exchange LLC board of directors);
•: three directors are selected by AMEX (provided that at least one of these three directors is not an officer or employee of AMEX);
•: one director is jointly selected by the NYSE and AMEX (it is contemplated that this director will also serve as the chief executive officer of SIAC); and
•: three directors are selected by the Securities Industry Association.

The directors are divided into two classes, designated as Class A directors and Class B directors. Each class of directors is elected for a two-year term so that the term of office of one class of directors expires each year. Gerald Putnam, who is NYSE Group's president and co-chief operating officer, is chairman of the SIAC board of directors.

The SIAC board of directors has two standing committees: the executive committee and the audit committee. The executive committee is comprised of five members of the SIAC board of directors. The executive committee's responsibilities include:

•: reviewing the management personnel needs, structure and policies of SIAC;
•: reviewing the current and anticipated financial requirements of SIAC; and
•: functioning as SIAC's compensation committee for the purpose of reviewing and approving the compensation plans and guidelines for all employees and the officers of SIAC.

The audit committee is comprised of three members of the SIAC board of directors. Its responsibilities are to assist the SIAC board of directors in fulfilling its financial accounting oversight responsibilities. In this

218

capacity, the audit committee reviews the financial reporting process, the system of internal controls and the process by which SIAC maintains compliance with applicable laws, rules and regulations.

The NYSE, AMEX and SIAC are parties to a shareholders agreement that governs the respective rights of the NYSE and AMEX relating to SIAC. Under the shareholders agreement, neither the NYSE nor AMEX may transfer any of their shares in SIAC to a third party without the consent of the other party, unless this transfer occurs:

•: by operation of law, by reason of insolvency or other cause; or
•: upon completion of a right-of-first-refusal process, in which the other party has the right to acquire any SIAC shares proposed to be transferred by either the NYSE or AMEX to a third party at the lower of:
•: the price offered by the third party seeking to acquire such SIAC shares; or
•: the "option price" agreed upon by the NYSE and AMEX from time to time or established by a five-person committee consisting of two representatives appointed by each of the NYSE and AMEX and one person appointed by the four members. (There is currently no determined option price.)

Major Customers

SIAC provides data processing services to NYSE and AMEX. In addition, SIAC operates the Intermarket Trading Systems and provides services to the Intermarket Surveillance Group Participants, the CTA Plan and CQ Plan and the Options Price Reporting Authority. SIAC also provides services to Sector.

219

Facilities Management Agreement

SIAC provides services to the NYSE and AMEX pursuant to an agreement dated February 23, 1977, among the NYSE, AMEX and SIAC, as amended, and a Paying Agency Agreement dated August 23, 2004 (which this document refers to collectively as the "facilities management agreement"). The facilities management agreement provides for services to be provided and products to be obtained by SIAC on behalf of or for use by the NYSE or AMEX, as either may request, at SIAC's cost. The facilities management agreement also provides that the NYSE or AMEX may request that the services to be provided to it be added to, modified or terminated, and that SIAC will "use its best efforts, consistent with sound business practices, to adapt to the changed requirements of each exchange for services rendered by SIAC."

Generally, the at-cost basis for service charges under the facilities management agreement includes dedicated manpower (such as salaries, overtime, part-time help and benefits); dedicated data processing or communications supplies and equipment; dedicated general expenses (such as office supplies, photocopy equipment, local transportation and travel); and shared common expenses (such as occupancy costs, facilities engineering support, security services and other non-dedicated manpower and related expenses, etc.), as well as any costs for products or services from third-party vendors. Costs are billed to the NYSE (and AMEX) on a monthly basis.

The facilities management agreement requires SIAC to recognize individual ownership rights on the part of the NYSE or AMEX of properties acquired by SIAC at the respective direction and expense of the NYSE and AMEX and joint ownership rights on the part of the NYSE and AMEX of properties acquired by SIAC for services provided to both the NYSE and AMEX. The agreement requires SIAC to maintain confidentiality regarding services it undertakes for each of the NYSE and AMEX and with regard to certain information obtained by SIAC in connection with the provision of services.

Separate services agreements cover services provided by SIAC to Options Price Reporting Authority and to the participants in the CTA Plan and the CQ Plan.

Recent Developments

NYSE Group and AMEX are SIAC's largest customers and, accordingly, the loss of the business of either could have a material adverse effect on SIAC. The National Securities Clearing Corporation and Fixed Income Clearing Corporation have entered into separate agreements with SIAC, pursuant to which the services previously provided by SIAC have been phased out. In addition, AMEX has sent a notice to SIAC indicating that it intends to materially decrease its use of SIAC's services. Negotiations with AMEX are currently being held with a view to such a material decrease in SIAC services provided to AMEX and the possible purchase of the shares of SIAC held by AMEX. No definitive agreements have yet been reached. If AMEX materially decreases its use of SIAC's services, as is presently anticipated, SIAC's revenues will be adversely affected. To the extent that AMEX does not bear a portion of the costs associated with this decrease (including transition costs and an appropriate share of SIAC's current overhead as SIAC seeks to mitigate the overhead costs), or to the extent that NYSE Group is not able to reduce its costs associated with SIAC to offset the amount of reduction in revenue from SIAC (which it may not be able to do), NYSE Group's profits and results of operations may be adversely affected. In order to reduce costs, SIAC has started to out source its finance and human resources functions to NYSE Group. See also "Risk Factors—Risks Relating to NYSE Euronext's Business—NYSE Euronext's revenues from SIAC could significantly decrease if SIAC loses major customers." In connection with any agreement for a material decrease in the SIAC services provided to AMEX, NYSE Group may purchase the 33% of SIAC's shares held by AMEX. Such a development could lead to the changes in the governance of SIAC described above and could result in changes to the Facilities Management Agreement described above. In addition, the shareholder agreement described above would be terminated.

NYSE Regulation

Overview. The NYSE and NYSE Arca, Inc. are responsible for examining compliance with and enforcing the financial, operational and sales-practice rules and codes of conduct for members, member organizations and their employees, and have responsibility for regulatory review of their trading activities. In addition, the NYSE and NYSE Arca, Inc. are responsible for enforcing compliance with their respective listing standards and corporate governance requirements by listed companies.

The regulatory functions of the NYSE and NYSE Arca, Inc. are performed by NYSE Regulation, Inc., a separate not-for-profit subsidiary of NYSE Group. NYSE Regulation consists of the following five divisions and a risk assessment unit, employing approximately 708 people as of June 30, 2006:

•: Listed Company Compliance;
•: Member Firm Regulation;
•: Market Surveillance;
•: Enforcement; and
•: Dispute Resolution/Arbitration.

Listed Company Compliance. The NYSE and NYSE Arca, Inc. require their listed companies to meet their respective original listing criteria at listing, and to thereafter maintain continued compliance with their respective listing standards. The Listed Company Compliance division monitors and enforces compliance with these standards. The division is split into two parts:

•: the financial compliance group, which reviews a company's reported financial results both at the time of listing and thereafter to ensure that it meets original listing and continued-listing requirements; and
•: the corporate compliance group, which ensures that listed companies adhere to the highest standards of accountability and transparency, including governance requirements for configuration of corporate boards, director independence and financial competence of audit committee members.

The rules of the NYSE and NYSE Arca, Inc. regulating the original and continued listing of companies are subject to review and approval by the SEC.

Member Firm Regulation. The Member Firm Regulation division conducts examinations of the more than 325 member organizations of the NYSE (representing approximately 90% of the total public customer accounts handled by broker-dealers in the United States), and more than 35 members of NYSE Arca, Inc. (for which it is the designated examining authority), for financial, operations and sales-practice compliance. In addition, the Member Firm Regulation division interprets and develops NYSE rules, develops and administers various industry qualifications and examinations, and administers the NYSE's continuing education programs for registered persons in the securities industry. As the primary self-regulator for its member organizations, Member Firm Regulation seeks to minimize duplication of effort with other regulatory organizations. Whenever feasible, examinations are conducted jointly with other self-regulatory organizations or responsibilities are allocated with the objective of increasing the cost effectiveness of self-regulation.

Market Surveillance. The Market Surveillance division is responsible for, among other things, monitoring equity insider trading activities on the facilities of the NYSE. Such monitoring of trading activities involves both real-time and post-trade review. The Market Surveillance division reviews transactions to determine whether auction-market rules and principles are being complied with and fairly maintained, and whether such transactions involve abusive or manipulative trading practices. The Market Surveillance division uses sophisticated computer technology to detect unusual trading patterns, and the staff of the Market Surveillance division also maintains a presence on the trading floor of the NYSE.

221

Market Surveillance makes referrals to the NYSE Enforcement division and the SEC Division of Enforcement, as appropriate. NYSE Arca maintains a surveillance group that is responsible for monitoring equities and options trading on that market.

Enforcement. The Enforcement division investigates and prosecutes violations of NYSE and NYSE Arca rules and U.S. federal securities laws and regulations. Enforcement cases include customer-related sales practice violations, breaches of financial and operational requirements, books and records deficiencies, reporting and supervisory violations, misconduct on the trading floor, insider trading, market manipulation and other abusive trading practices. Sources of cases for the Enforcement division include examination findings referred by the Member Firm Regulation division, surveillance reviews referred by the Market Surveillance division, arbitration referrals from the Dispute Resolution/Arbitration division, reviews of customer complaints by the Enforcement division, settlements and reporting by member organizations, referrals from the SEC and complaints by members of the investing public and securities professionals. In 2005, the Enforcement division prosecuted 196 NYSE cases, comprised of 138 actions against individuals and 58 actions against member organizations. All settlements negotiated between Enforcement and a respondent must be reviewed and approved by the Office of the Hearing Board, which is independent of NYSE Regulation management, before becoming final. Contested hearings are also conducted before hearing panels under the purview of the Hearing Board, which operates much like an administrative tribunal.

Dispute Resolution/Arbitration. The Dispute Resolution/Arbitration division provides a neutral forum for the resolution of securities industries disputes in more than 46 cities throughout the United States. For more than 125 years, the NYSE has used arbitration to resolve disputes between investors and member organizations/brokers and between member organizations and their employees. Arbitration enables a dispute to be resolved quickly and fairly by impartial arbitrators, who are knowledgeable and trained in the art of resolving controversy. Mediation is another dispute resolution option that the NYSE offers. This is a voluntary process in which a neutral mediator meets with the parties and attempts to help them reach a settlement. Mediation is not binding, is not adversarial and no record of the mediation is kept. NYSE Arca provides its own arbitration forum, which is administered by the same staff that administers the NYSE arbitration program.

Structure, Organization and Governance of NYSE Regulation. NYSE Regulation has undertaken the regulatory functions of the New York Stock Exchange LLC and NYSE Arca, Inc. pursuant to agreements with each entity. NYSE Regulation also has an explicit agreement with NYSE Group, New York Stock Exchange LLC and NYSE Market so that adequate funding is provided to NYSE Regulation. Moreover, under the operating agreement of New York Stock Exchange LLC, no regulatory fees, fines or penalties collected by NYSE Regulation may be distributed to NYSE Group or any entity other than NYSE Regulation.

NYSE Regulation expects to be self-funded through its collection of regulatory fees and fines and through its agreements with New York Stock Exchange LLC, NYSE Market and NYSE Arca, Inc. to provide regulatory services. NYSE Regulation levies fines as a result of formal disciplinary action imposed by the Enforcement division of NYSE Regulation. When the Enforcement division determines that there has been a violation of law or SEC or NYSE rules, it prepares an enforcement action memorandum that includes a range of sanctions for settlement purposes or for the recommendation of a sanction in the event that the matter is contested. NYSE Regulation may consider the following factors, among others, in determining the level of the sanction:

•: the nature of the misconduct and the degree of scienter;
•: the harm caused by the misconduct;
•: the extent of the misconduct;

222

•: the prior disciplinary record of the respondent;
•: the implementation of corrective measures and restitution;
•: deceptive conduct, neglect or disregard of "red flags" on the part of the respondent;
•: the effectiveness of the respondent's operational, supervisory and compliance controls; and
•: the respondent's size and financial resources and cooperation.

In addition, the Enforcement division considers prior precedents in determining the level of sanction, including any applicable NASD and SEC matters that are analogous to the case at hand. The Enforcement division receives input from other regulatory divisions as appropriate to verify consistency in terms of charges being recommended and the sanction level. The chief executive officer of NYSE Regulation reviews and approves the recommended level of sanction. Respondents can either settle, which will result in a signed stipulation of facts and consent to penalty, or can contest the matter and proceed to a hearing on the charges.

In the event of a settlement, the stipulation and consent will be presented to the Hearing Board. The Hearing Board can accept or reject the settlement. If the respondent wishes to contest the matter, a charge memorandum will be issued to the respondent, who has 25 days to answer and the matter is brought before a hearing panel to decide. In the event that the respondent is found guilty, a sanction is imposed by the hearing panel that may include a fine. There is an appellate process for such decision that starts with the NYSE Regulation board, then proceeds to the SEC, and then to the federal court of appeals.

NYSE Regulation has budgeted conservatively for regulatory fines, and they are not considered in its fee structure. NYSE Regulation does not adjust the amount of regulatory fees charged based on the amount of fines assessed. The NYSE Regulation Board continues to review how fines will be used going forward.

NYSE Regulation incorporates several structural and governance features designed to ensure its independence, given the status of NYSE Group as a for-profit and listed company prior to the combination and NYSE Euronext's status as a for-profit and listed company after the combination. For example, the NYSE Euronext's certificate of incorporation will contain ownership and voting limitations to prevent any stockholder from having undue control over NYSE Euronext (and therefore the SROs owned by NYSE Euronext). See "Description of Capital Stock—Ownership and Voting Limits on NYSE Euronext Capital Stock" and its certificate of incorporation, which contains provisions that require that:

•: NYSE Euronext gives due regard to the preservation of the independence of the self-regulatory function of its SROs and to their obligations to investors and the general public;
•: NYSE Euronext does not take any action that would interfere with the effectuation of any decisions by the board of directors of its SROs relating to their regulatory functions (including disciplinary matters) or that would interfere with the ability of its SROs to carry out their respective responsibilities under the Exchange Act;
•: NYSE Euronext generally keeps confidential information pertaining to the self-regulatory function of its SROs that comes into its possession;
•: NYSE Euronext , its directors and officers, and those of its employees whose principal place of business and residence is outside of the United States, submit irrevocably to the jurisdiction of the U.S. federal courts and the SEC for the purposes of any suit, action or proceeding pursuant to the U.S. federal securities laws, and the rules and regulations thereunder, commenced or initiated by the SEC arising out of, or relating to, the activities of its SROs; and

223

•: NYSE Euronext's directors, officers and employees, in discharging their responsibilities in such capacity, cooperate with the SEC and NYSE Euronext's SROs pursuant to their regulatory authority.

In addition, NYSE Regulation operates as a not-for-profit entity, rather than as a for-profit entity. The chief executive officer of NYSE Regulation is also not permitted to be an officer or employee of any unit of NYSE Euronext other than NYSE Regulation and reports solely to the NYSE Regulation board of directors. To reduce the conflicts that arise from "self listing," NYSE Regulation will be responsible for all listing compliance decisions with respect to NYSE Euronext as an issuer, and NYSE Regulation will provide the SEC with periodic reports summarizing its monitoring of NYSE Euronext's common stock. These reports will be approved by the NYSE Regulation board of directors, including a separate approval by the directors of NYSE Regulation who are not directors of NYSE Euronext. In addition, NYSE rules require an annual review by an independent accounting firm to insure that NYSE Euronext is in compliance with the listing requirements, and a copy of this report must be forwarded to the SEC.

NYSE Regulation has adopted structural and governance standards in compliance with applicable U.S. federal securities laws, and in particular, Section 6 of the Exchange Act with respect to fair representation of members. Such structure and governance standards will be adjusted to comply with any rules finally adopted by the SEC following its proposals relating to governance, transparency, oversight and ownership of SROs.

These structural and governance arrangements currently include the following:

•: NYSE Regulation is a separately incorporated, not-for-profit entity;
•: each director of NYSE Regulation (other than its chief executive officer) must be independent under the independence policy of the NYSE Group board of directors;
•: a majority of the members of the NYSE Regulation board of directors and its compensation and nominating committee must be persons who are not directors of NYSE Group; and
•: NYSE Regulation funds its programs, including surveillance, examination, testing and continuing education services, through fees assessed directly on member organizations. NYSE Regulation is also compensated for the regulatory services provided to the NYSE and NYSE Arca, Inc. pursuant to agreements with each entity.

Following the combination, these structural and governance arrangement will continue except that:

•: each director of NYSE Regulation (other than its chief executive officer) will be required to be independent under the independence policy of the NYSE Euronext board of directors (as opposed to the policy of the NYSE Group board of directors); and
•: a majority of the members of the NYSE Regulation board of directors and its compensation and nominating committee will be required to be persons who are not directors of NYSE Euronext (as opposed to NYSE Group).

Technology and Intellectual Property

Technology

The NYSE and NYSE Arca each employ a wide range of technologies which are crucial to NYSE Group's business. Technology enables NYSE Group to maintain its competitive position and regulatory effectiveness as well as investor confidence in the reliability and integrity of its trading platforms and markets. NYSE Group is committed to the ongoing development, maintenance and use of technology and to providing its customers with technological solutions. NYSE Group's technology is subject to oversight by the SEC, through the SEC's Automation Review Program.

224

NYSE Group's technological initiatives are focused on satisfying each of the objectives set forth below:

•: Functionality—business-driven requirements should be delivered on time and with minimal defects;
•: Performance—systems should provide fast and competitive response times;
•: Capacity/Scalability—systems should be capable of supporting present needs and expanding to meet projected demands;
•: Reliability—the availability and performance should satisfy NYSE Group's goals and objectives; and
•: Total cost of ownership—systems and operating environment should be managed with a competitive cost structure.

NYSE Group's position in the capital markets requires substantial investments in business continuity, including back-up data centers, back-up trading floors and physical and information security. These investments have increased substantially following the terrorist attacks of September 11, 2001. Business drivers for NYSE Group's technology investments include:

•: continual functional and performance improvements to NYSE Group's execution services and information products to address customer needs and the evolving competitive trading environment;

Legal Proceedings

NYSE Group is party to a number of legal proceedings, as described below.

In re NYSE Specialists Securities Litigation

In December 2003, the California Public Employees' Retirement System ("CalPERS") filed a purported class action complaint in the U.S. District Court for the Southern District of New York against NYSE, NYSE specialist firms, and others, alleging various violations of the Exchange Act and breaches of fiduciary duty, on behalf of a purported class of persons who bought or sold unspecified NYSE-listed stocks between 1998 and 2003. The court consolidated CalPERS' suit with three other purported class actions and one other non-class action suit into an action entitled In re NYSE Specialists Securities Litigation. The court also appointed CalPERS and Empire Programs, Inc. as co-lead plaintiffs.

Plaintiffs filed a consolidated complaint on September 16, 2004. The consolidated complaint asserts claims for alleged violations of Sections 6(b), 10(b) and 20(a) of the Exchange Act, and alleges that, with NYSE's knowledge and active participation, the specialist firms engaged in manipulative, self-dealing and deceptive conduct, including interpositioning, front-running and "freezing" the specialist's book and falsifying trading records to conceal their misconduct. Plaintiffs also claim that NYSE constrained its regulatory activities in order to receive substantial fees from the specialist firms based on their profits, which "caused investors to purchase or sell shares on the NYSE at distorted and manipulated prices, enriching Defendants and damaging Plaintiffs and the Class." The consolidated complaint also alleges that certain generalized NYSE statements concerning the operation of its market were rendered false and misleading by NYSE's non-disclosure of its alleged failure to properly regulate specialists, and that NYSE was motivated to participate in or permit the specialist firms' alleged improper trading in order to maintain or enhance its fee revenues and the compensation of its executives, including its former chairman and chief executive officer Richard A. Grasso. The consolidated complaint seeks unspecified compensatory damages against defendants, jointly and severally.

On November 16, 2004, the specialist firms and NYSE filed motions to dismiss the complaint. On December 12, 2005, the court issued an order granting NYSE's motion and dismissing all of the claims against it with prejudice, and granting in part and denying in part the specialist defendants' motion to dismiss. On February 17, 2006, the court entered a final judgment in favor of NYSE. Plaintiffs appealed the judgment and on June 2, 2006, filed in the U.S. Court of Appeals for the Second Circuit an opening brief in support of that appeal. NYSE filed its brief in opposition on August 2, 2006.

229

Papyrus Patent Infringement Litigation

On January 27, 2004, Papyrus Technology Corporation filed a complaint in the U.S. District Court for the Southern District of New York against NYSE, alleging that NYSE's Wireless Data System and Broker Booth Support System infringe patents allegedly issued to Papyrus, and that NYSE breached a license agreement with Papyrus. NYSE answered the complaint, asserting affirmative defenses and a counterclaim against Papyrus. Discovery has been completed. It is anticipated that the parties will file motions for summary judgment on at least some of the claims. The court has not set a trial date.

Grasso Litigation

In December 2003, NYSE received a report from the law firm Winston & Strawn, which NYSE had engaged to investigate and review certain matters relating to the compensation of its former chairman and chief executive officer, Richard A. Grasso, and the process by which that compensation was determined (this document refers to this report as the "Webb Report"). NYSE provided the Webb Report to the SEC and the New York Attorney General's Office, which commenced investigations relating to those matters in or about January 2004.

The Webb Report provided a detailed summary of, among other things, Mr. Grasso's compensation and benefits during the period during which he served as Chairman and Chief Executive Officer of NYSE (1995-2003), including the various components thereof. On or about September 2, 2003, NYSE transferred to Mr. Grasso $139,486,000 in respect of deferred compensation and benefits for that period. Previously, NYSE had transferred to Mr. Grasso approximately $35 million in non-deferred compensation for that period.

On or about February 12, 2004, NYSE's then Interim Chairman, John S. Reed, sent Mr. Grasso a letter stating that NYSE had determined that the compensation and benefits that Mr. Grasso received "were excessive and at unreasonable levels" and that, even granting Mr. Grasso the benefit of assumptions favorable to him, compensation and benefits "were excessive by at least $120 million." In that letter, NYSE demanded that Mr. Grasso repay $120 million to NYSE and reserved its rights to seek additional amounts beyond the $120 million demanded.

On May 24, 2004, the New York Attorney General filed a lawsuit in New York Supreme Court against Mr. Grasso, former NYSE Director Kenneth Langone and NYSE. The complaint alleges six causes of action against Mr. Grasso, including breach of fiduciary duty under the New York Not-for-Profit Corporation Law and unjust enrichment. Among other things, the suit seeks:

•: imposition of a constructive trust for NYSE's benefit on all compensation received by Mr. Grasso that was not reasonable and commensurate with services rendered, pursuant to provisions of the New York Not-for-Profit Corporation Law "in an amount to be determined at trial;"
•: a judgment directing Mr. Grasso to return payments made by NYSE that were unlawful under the New York Not-for-Profit Corporation Law "in an amount to be determined at trial;" and
•: restitution of all amounts that Mr. Grasso received that lacked adequate NYSE board approval because the board's approval was based on inaccurate, incomplete or misleading information.

The New York Attorney General further seeks a declaration by the court that any obligation to make future payments to Mr. Grasso by NYSE lacking the required board approval is void. In addition to the claims against Mr. Grasso, the complaint asserts a single cause of action against Mr. Langone for breach of his fiduciary duty under the New York Not-for-Profit Corporation Law and a single cause of action against NYSE seeking a declaratory judgment that NYSE made unlawful, ultra vires payments to Mr. Grasso, and an injunction requiring NYSE to adopt and implement safeguards to ensure that future compensation complies with the New York Not-for-Profit Corporation Law. On July 23, 2004, NYSE filed its answer to the complaint of the New York Attorney General, in which it asserted several complete defenses.

230

In his answer, Mr. Grasso denied the New York Attorney General's allegations of wrongdoing and asserted various defenses. In addition, Mr. Grasso asserted claims against NYSE and Mr. Reed, including claims that: (1) NYSE terminated Mr. Grasso without cause in September 2003; (2) NYSE breached his 1999 and 2003 employment agreements; and (3) NYSE and Mr. Reed defamed him. Mr. Grasso has not claimed with specificity the amount of damages that he seeks in the litigation. In his pleadings, he seeks at least $50 million in compensatory damages for NYSE's alleged breaches of the agreements; damages for alleged injury to his reputation and mental anguish and suffering; and punitive damages against Mr. Reed and NYSE. In or about March 2005, Mr. Grasso asserted third-party claims against former NYSE Director Carl McCall for negligence, negligent misrepresentation and contribution. In August 2005, Mr. Grasso moved to dismiss four of the six causes of action alleged by the New York Attorney General. On March 15, 2006, the court denied Mr. Grasso's motion; Mr. Grasso has filed an appeal of that decision. In January 2006, Mr. Langone moved for summary judgment on the single cause of action asserted against him by the New York Attorney General. On July 26, 2006, the court denied Mr. Langone's motion; Mr. Langone has appealed that denial. On July 17, 2006, NYSE and Mr. Reed filed motions for summary judgment dismissing all of Mr. Grasso's counterclaims against them. On July 31, 2006, the New York Attorney General filed a motion for partial summary judgment in its favor on claims asserted against Mr. Grasso, and Mr. Grasso filed motions for summary judgment in his favor with respect to three of the six causes of action asserted against him by the New York Attorney General. Mr. Grasso also has moved for summary judgment dismissing the one claim asserted against NYSE by the New York Attorney General. Mr. McCall moved for summary judgment dismissing the third-party claims asserted against him by Mr. Grasso; on August 23, 2006, the court granted Mr. McCall's motion and dismissed the third-party claims. On August 8, 2006, the court ruled that the New York Attorney General's claim against Mr. Grasso for restitution and imposition of a constructive trust is an equitable claim that must be tried to the court rather than to a jury, and that it would commence trial of that claim alone on October 16, 2006. Mr. Grasso filed an appeal of that decision, and on September 14, 2006, the appellate court entered an order staying the trial until the appeals of that decision, and of the earlier decision denying Mr. Grasso's motion to dismiss, have been decided. On September 7, 2006, Mr. Grasso filed a motion seeking reassignment of the case to a different judge for all further proceedings, and on September 14, 2006, the court denied that motion.

The Webb Report stated that the total amount of excessive compensation and benefits actually received by Mr. Grasso was within the range of approximately $113 million to $125 million (including both deferred and non-deferred compensation and benefits paid to Mr. Grasso). The specific amounts of compensation and benefits that should be repaid by Mr. Grasso will be the subject of expert testimony during the expert discovery phase of the litigation. If the New York Attorney General prevails on all of his claims, the court will order Mr. Grasso to return to NYSE portions of his compensation and benefits determined at trial to be unreasonable and declare that the alleged obligation of NYSE to make further payments is void.

The ultimate outcome of the above litigations cannot reasonably be determined at this time.

Merger-Related Litigation

On July 12, 2005, Allison L. Wey filed a complaint in New York Supreme Court against NYSE and the chief executive officer of NYSE, John A. Thain, alleging causes of action for fraud, negligent misrepresentation and breach of fiduciary duty, and seeking unspecified compensatory damages. Ms. Wey, a former NYSE member, alleges that in connection with the sale of her NYSE membership on March 21, 2005, she relied to her detriment on statements that Mr. Thain allegedly made to certain NYSE members on February 15, 2005 regarding NYSE's intention to "go public." NYSE and Mr. Thain believe that the claims are without merit. NYSE and Mr. Thain filed an answer to the complaint on December 23, 2005; the case presently is in discovery.

In March 2006, Janet Hyman and Sylvia Lief, former NYSE members, filed separate complaints in New York Supreme Court against NYSE and Mr. Thain. The complaints sought compensatory damages

231

for alleged breach of fiduciary duty based on a purported duty of defendants to disclose NYSE's merger discussions with Archipelago prior to the sale of plaintiffs' NYSE memberships on March 1 and 2, 2005, respectively.

On April 19, 2006, NYSE and Mr. Thain served motions to dismiss the Hyman and Lief complaints. On June 9, 2006, Ms. Hyman and Ms. Lief each served an amended complaint, which added an additional cause of action for breach of fiduciary duty and a new cause of action for negligence. On June 22, 2006, D. Paul Rittmaster, another former NYSE member represented by the same law firm as Ms. Hyman and Ms. Lief, filed a complaint in New York Supreme Court against NYSE and Mr. Thain asserting the same causes of action alleged in the amended complaints of Ms. Hyman and Ms. Lief. On July 28, 2006, NYSE and Mr. Thain served a motion to dismiss the Hyman and Lief amended complaints and the Rittmaster complaint on the ground, among others, that defendants had no legal duty to make the disclosures plaintiffs assert they should have made.

Employment-Related Litigation

On April 20, 2006, Graciela DaSilva, Vjoca Selmanovic and Robin Max Morris filed a complaint in the U.S. District Court for the Southern District of New York against NYSE Group, Building Maintenance Service, LLC ("BMS") and five unnamed corporations, seeking compensatory and punitive damages for alleged gender discrimination and retaliation in violation of federal and local laws. Plaintiff DaSilva currently is employed as a porter by NYSE Group; Morris previously was employed by NYSE as a supervisor of porters. Selmanovic previously was employed as a porter by BMS, a cleaning service contractor. On May 24, 2006, NYSE Group filed an answer to the complaint in which it denied allegations of wrongdoing and asserted various defenses.

Listing Claim Letter

On September 7, 2005, NYSE postponed commencement of trading of the stock of Life Sciences Research ("LSR") on NYSE. On or about April 5, 2006, NYSE Group received a letter from counsel for LSR enclosing a draft complaint alleging breach of alleged agreements with LSR, including to list LSR stock, and seeking specific performance, damages, and other relief. The letter expressed LSR's interest in resolving the matter without litigation. Neither the likelihood of LSR's actually commencing a lawsuit nor the ultimate outcome of such a suit can reasonably be determined at this time.

IBAC Matter

On or about April 25, 2006, the Independent Broker Action Committee, Inc. ("IBAC"), which describes itself as a not-for-profit corporation whose membership consists of independent NYSE brokers, filed a petition in the U.S. Court of Appeals for the District of Columbia (the "DC Circuit") seeking review of two orders issued by the SEC (Exchange Act Release No. 34-53539 (March 22, 2006) and 34-53382 (February 27, 2006) (the "Orders")) insofar as they relate to the creation of the NYSE Hybrid Market^SM and NYSE's proposed method of allocating trading rights. The petition named only the SEC as respondent and asked the Court to vacate Exchange Act Release No. 34-53539 regarding the NYSE Hybrid Market^SM and that portion of Exchange Act Release No. 34-53382 that approved NYSE's proposed method of allocating trading rights at NYSE through annual trading licenses, and to remand the matter to the SEC for further proceedings. IBAC also asked the SEC to stay the authorization given to NYSE under Exchange Act Release No. 34-53539 to implement subsequent phases of the NYSE Hybrid Market^SM, pending the Court's resolution of IBAC's petition for review. NYSE opposed IBAC's stay request before the SEC and was granted leave to intervene to oppose IBAC's petition before the DC Circuit. Following joint requests to the SEC and the DC Circuit, the SEC has deferred ruling on IBAC's stay request and the DC Circuit has deferred briefing on the petition itself, to allow IBAC to determine whether it wishes to continue to pursue the petition in light of subsequent developments with regard to the NYSE Hybrid Market^SM.

232

Matters Relating to Gerald D. Putnam

In addition to the matters described above, Gerald D. Putnam, NYSE Group's president and co-chief operating officer, was or is currently involved in the following legal proceedings. Archipelago had previously been a party to each of the matters described below; however, Archipelago has since been dismissed from each matter.

Borsellino Litigation. In September 2000, plaintiffs Lewis Borsellino, a former business partner of Mr. Putnam and equity holder in Chicago Trading and Arbitrage ("CTA"), and I.M. Acquisitions, L.L.C, an entity owned by Mr. Borsellino, filed a complaint in Illinois State Circuit Court naming Mr. Putnam and other former members of CTA as defendants. The complaint alleged that Mr. Putnam and the other defendants secretly diverted assets of CTA to their other business ventures. The complaint also alleged that a 1998 Settlement Agreement between the parties addressing these allegations was based on fraud, and that defendants violated their fiduciary duties with respect to plaintiffs by allegedly failing to disclose material information during the 1998 settlement negotiations. Archipelago L.L.C. (the predecessor company to Wave Securities, L.L.C.) was also named as a defendant in this action although it was never a member of CTA.

On April 11, 2001, the court dismissed Archipelago L.L.C. and the other defendants with prejudice from the September 2000 complaint. In May 2001, plaintiffs filed a motion to vacate the court's dismissal order and for leave to file an amended complaint against the original defendants.

In November 2001, the court granted plaintiffs' motion and allowed plaintiffs to file their amended complaint against Mr. Putnam and the other defendants, except Archipelago L.L.C.

On January 16, 2002, plaintiffs filed a second amended complaint that sought compensatory and punitive damages in excess of $80.0 million, as well as reimbursement of attorneys' fees and the cost of litigation.

On March 24, 2004, plaintiffs filed a motion for leave to file a third amended complaint, which, if granted, would replace the second amended complaint. On April 28, 2004, defendants filed a motion in opposition to plaintiffs' motion for leave to file a third amended complaint. On September 23, 2005, plaintiffs filed a different third amended complaint against Putnam, and the other defendants. The third amended complaint is a one-count fraud claim seeking the same relief as the second amended complaint and containing additional similar allegations against defendants. Defendants have filed numerous motions to dismiss the third amended complaint.

In addition to the litigation described above, on March 23, 2004, plaintiffs filed a separate complaint against Archipelago Holdings, L.L.C. and "ArcaEx" alleging, among other things, unjust enrichment in connection with the alleged activities of the CTA member defendants, including Mr. Putnam. On September 14, 2004, the Illinois Circuit Court entered an order dismissing both Archipelago Holdings, L.L.C. and "ArcaEx" from this litigation with prejudice.

Lozman Litigation. Archipelago L.L.C., Archipelago Holdings, L.L.C., Terra Nova Trading, L.L.C. ("Terra Nova"), an investor in Archipelago and Mr. Putnam, were named as defendants in a civil action filed in the Circuit Court of Cook County, Illinois, on August 9, 1999. One plaintiff, Fane Lozman, is a former business associate of Mr. Putnam, and another plaintiff, Blue Water Partners, Inc., is a corporation owned by Mr. Lozman. Mr. Putnam was, at one time, its president. The wrongful conduct alleged in plaintiffs' complaint predates Archipelago's formation in December 1996. Plaintiffs alleged that Archipelago: (1) breached a joint venture agreement with plaintiffs; (2) engaged in corporate oppression in violation of Illinois law; (3) usurped corporate opportunities belonging to plaintiffs in the form of plaintiffs' "ideas" concerning electronic communication networks, electronic trading and electronic stock exchanges; (4) breached duties of good faith and fair dealing; and (5) conspired with the other defendants to injure plaintiffs. The lawsuit seeks, among other relief, money damages, an accounting and the imposition of a constructive trust on all property, benefits, profits and unjust enrichment defendants have

233

received and will receive by virtue of the alleged wrongful acts. NYSE Group believes these claims relate only to Terra Nova's ownership in Archipelago and any direct or indirect interest of Mr. Putnam, Stuart Townsend and MarrGwen Townsend in Archipelago.

The Circuit Court dismissed all of plaintiffs' claims against Archipelago on March 20, 2000. In April 2002, the Appellate Court of Illinois affirmed the Circuit Court's order of dismissal, except that it determined that it did not have appellate jurisdiction to review the dismissal of plaintiffs' claims against Archipelago for usurpation of corporate opportunities, which contend that Archipelago is derivatively liable for the conduct of the remaining defendants.

With regard to the remaining claims against Mr. Putnam and Terra Nova, a trial by jury commenced in November 2004. On December 16, 2004, the jury rendered binding verdicts on the oral and written contract claims and found Mr. Putnam and Terra Nova not liable. The jury also found that the releases executed in 1995 by and between plaintiffs, Mr. Putnam and Terra Nova, were valid and enforceable. As for the claim that Mr. Putnam breached his fiduciary duty to plaintiffs, the jury issued an advisory verdict to the judge in which it determined that Mr. Putnam and Terra Nova had usurped a corporate opportunity in violation of their fiduciary duties. The jury also answered a non-binding special interrogatory in which it valued the usurped opportunity at $2.5 million. However, the judge determined that because plaintiffs' fiduciary duty claim is equitable in nature, the judge, rather than the jury, would make the final, binding determination as to Mr. Putnam's liability under this claim and the amount of damages. On July 25, 2005, the court entered a final judgment in favor of Mr. Putnam and the other defendants on all counts, including plaintiffs' claim of usurpation of corporate opportunity and breach of fiduciary duty. Plaintiffs filed a notice of appeal on March 31, 2006.

Director Compensation and Indemnification

Pursuant to the Directors' Compensation Policy adopted June 1, 2006, NYSE Group directors (other than the chairman and chief executive officer) are entitled to an annual fee of $100,000. The chairman of the board is entitled to an annual fee of $350,000. The foregoing annual fees are payable 50% in cash, and 50% in Restricted Stock Units granted under the 2006 Stock Incentive Plan. The RSUs granted to each director will be distributed after the director's retirement, resignation or other termination (except for cause). Additional annual fees, payable entirely in cash, of (a) $25,000 are payable to the Chairperson of Audit Committee and (b) $10,000 are payable to the chairpersons of Nominating and Governance Committee and the Human Resources and Compensation Committee, and to all members of the Audit Committee other than the chairperson. These additional annual fees are not payable to the chairman of the board, should he serve in any of the capacities for which additional annual fees are payable. Compensation for the 2006-2007 Board year was prorated to account for an anticipated 10-month interval between annual meetings. No NYSE Group director is entitled to receive an annual fee except upon request. NYSE Group directors are also reimbursed for their out-of-pocket travel expenses.

In addition to their compensation for service on the NYSE Group board, Directors Jackson and Brown each receive an annual fee of $50,000 cash for their service as directors on the board of NYSE Regulation, Inc. and Dr. Jackson receives an additional $25,000 for chairing the NYSE Regulation board.

The NYSE Group bylaws provide indemnification to NYSE directors and others against liability arising from their service to the full extent permitted by law. NYSE Group has obtained a directors and officers' liability insurance policy.

Executive Compensation

NYSE Group was created in 2005 for the purpose of consummating the merger of the NYSE and Archipelago. Prior to the completion of this merger on March 7, 2006, NYSE Group conducted no significant business. Thus, for the past three fiscal years, NYSE Group's officers and directors were not compensated by NYSE Group, but rather by the NYSE or Archipelago, as and to the extent indicated below. The table below sets forth for the last three fiscal years the compensation of the chief executive

235

officer of NYSE Group and the four most highly compensated executive officers (other than the chief executive officer) serving at the end of 2005, the last completed fiscal year.

(1): This table sets forth the compensation earned during the last three fiscal years of the chief executive officer of NYSE Group and the four most highly compensated executive officers (other than the chief executive officer) serving at the end of 2005, the last completed fiscal year. Because the merger of the NYSE and Archipelago was not completed until after the end of the last fiscal year of NYSE Group, the compensation for John A. Thain and Catherine R. Kinney represent compensation that they received as executive officers of the NYSE, and the compensation for Gerald D. Putnam, Nelson Chai and Kevin J.P. O'Hara represent compensation that they received as executive officers of Archipelago. Mr. Thain did not join the NYSE until January 15, 2004.
(2): Salaries were paid to Archipelago employees on a bi-weekly basis, and in 2004 there were 27 pay periods. As a result, the 2004 salaries for Messrs. Putnam, Chai and O'Hara include their respective base salary (consisting of $750,000 in the case of Mr. Putnam and $330,000 for Messrs. Chai and O'Hara), plus a payment for one additional pay period.
(3): The values of the restricted stock unit awards ("RSUs") as of grant date were determined for each named executive officer, respectively, by multiplying the number of RSUs awarded to each named executive officer by the fair market value of a share of Archipelago common stock on the grant date. Each RSU represents a right to receive one share of NYSE Group common stock upon vesting. The value at December 30, 2005 of RSUs granted in 2005 and 2004 to Mr. Putnam was $2,979,950 and $3,814,700, respectively, to Mr. Chai was $874,200 and $1,771,100, respectively, and to Mr. O'Hara was $874,200 and $1,771,100, respectively, based on a $50 per share fair market value of Archipelago common stock on December 30, 2005.
(4): Includes the following number of stock options granted on March 16, 2005 for the fiscal year ended December 31, 2004: 55,700 to Mr. Putnam and 25,648 for each of Messrs. Chai and O'Hara. These options have an exercise price of $19.30.
(5): Effective January 1, 2004, the Capital Accumulation Plan was frozen. No further credits to the Capital Accumulation Plan have been made for services performed after December 31, 2003. Prior awards continue to vest according to the vesting schedules. The award is treated as a book entry earning the interest rate of the 10-year U.S. treasury note in effect on the last business day of the prior calendar year until it is vested. Vesting is based solely on the age of the participant and continued employment. Once vested, the awards are transferred to a Rabbi Trust, where the rate of return is based on the individual participant's selection of investment vehicles. Participants may currently choose from

236

nine mutual funds as investment vehicles. Participants may elect to receive their vested account balances in a lump sum distribution or annual installments following termination of employment. The current vesting schedule is as follows:

Age		% Vested
<55		0
55		10
56		20
57		30
58		50
59		70
60		100

The: vesting schedule for amounts credited through the year 2000 provided similar percentage vesting but over an age range from 50 to 55 years of age.
(6): Includes (a) NYSE company match to the executive's Employee Savings Plan account and Supplemental Executive Savings Plan account, and (b) taxable term life insurance premiums. The NYSE permitted all employees with five weeks of vacation (those with 18 or more years of service) to "cash in" up to five vacation days per year. The NYSE also permitted all employees to similarly "cash in" up to six sick days per year. These amounts, if any, for the named executives are also included in this column. Effective January 1, 2005, the ability to "cash in" vacation and sick days was terminated. The NYSE eliminated reimbursement for initiation fees and annual dues for country clubs and other entertainment venues (other than for luncheon clubs) and for financial planning benefits, effective July 2004.
(7): Consists of contributions to a non-qualified deferred compensation arrangement pursuant to Mr. Thain's employment agreement.
(8): Includes matching contributions to the NYSE Supplemental Executive Savings Plan in the amount of $36,346.
(9): On December 30, 2005, Archipelago entered into agreements with Messrs. Putnam, Chai and O'Hara that accelerated cash payments that would have occurred in March 2006 following certain terminations after the completion of the merger. The NYSE consented under the merger agreement to the execution of these agreements and related cash payments of $7,875,000, $2,250,000 and $2,250,000 for Messrs. Putnam, Chai and O'Hara, respectively.
(10): On March 24, 2006, Mr. O'Hara submitted his resignation, which was effective on April 12, 2006.
: For business purposes only, NYSE Group provides three private aircraft, in each of which it owns a shared interest, a small number of cars with drivers and an apartment in New York City to various senior executive officers.

For additional information regarding Mr. Thain's Compensation, see "Information About NYSE Group—Executive Compensation—Agreements for Named Executive Officers—John A. Thain."

The following tables set forth information regarding stock options granted to those named executive officers in their capacity as executive officers of Archipelago. The underlying stock for all such options at the time of grant was Archipelago common stock. On March 7, 2006 the NYSE and Archipelago merged becoming wholly owned subsidiaries of NYSE Group and the underlying stock for such options was converted to NYSE Group common stock and certain of these options were accelerated.

Agreements for Named Executive Officers

John A. Thain

Pursuant to letter agreements with the NYSE, Mr. Thain served as the chief executive officer and a member of the board of directors of the NYSE at an annual base salary of $4,120,000. Under these letter agreements, Mr. Thain irrevocably waived his right to participate in any employee benefit plans, programs or arrangements of the NYSE, other than participation in the medical, dental, vision and short-term disability benefit plan portions of the NYSE's welfare benefit plan and the executive medical spending program. Mr. Thain is not eligible for an incentive award and does not participate in the Capital Accumulation Plan, the Supplemental Executive Retirement Plan ("SERP"), the Supplemental Executive Savings Plan ("SESP"), the Savings Plan or the Retirement Plan. In addition, Mr. Thain has agreed to defer $120,000 of his annual base pay each year, and the NYSE has agreed to credit Mr. Thain with a deemed matching contribution equal to $120,000 per year, all to be invested in the vehicles delineated under the SESP. This money may be withdrawn only after Mr. Thain reaches age 60.

Mr. Thain disclosed his then existing equity securities holdings to the NYSE in the letter agreements. Consistent with his responsibilities under the NYSE Officers' and Employees' Statement of Business Conduct and Ethics, the letter agreements reiterate his obligation to recuse himself from matters pertaining to his former employer, The Goldman Sachs Group, Inc. The NYSE employee ethics statement

238

precluded (and NYSE Group's employee ethics statement precludes) employees from owning equity securities of member organizations and requires new employees to divest any of these securities within six months of employment. At the time that he accepted the position of chief executive officer, Mr. Thain had significant holdings of The Goldman Sachs Group, Inc. equity securities. The NYSE board of directors determined to waive the divestiture requirement and, instead, to require Mr. Thain to place the securities in a blind trust.

The NYSE Group board of directors has proposed to Mr. Thain an amendment to his letter agreement that would reduce his annual base salary to $750,000, create a performance based incentive compensation with cash and equity targets totaling $5.25 million, for a total compensation target of $6 million, and cause him to participate in the benefit plans currently available to senior executives. In anticipation of the execution of the amended agreement, Mr. Thain's annual base salary was reduced to $750,000 as of April 17, 2006.

Letter Regarding Mrs. Kinney's Supplemental Executive Retirement Plan Benefits

The minimum SERP benefits established for Mrs. Kinney are documented in a letter. If Mrs. Kinney terminates employment at age 55, she will receive a life annuity under the SERP equal to $1,000,000 per year, which will increase ratably each year until the life annuity reaches $1,250,000 per year at age 60, at which point she will continue to receive $1,250,000 per year. The present value of the SERP benefit will be paid in ten annual payments in accordance with the terms of the SERP, as soon as practicable after the date of retirement. In addition, if Mrs. Kinney terminates employment prior to age 55, she is vested in $900,000 per year payable as a life annuity commencing at age 55. These amounts are offset by social security benefits beginning at age 62 but not by amounts payable to her under the Retirement Plan.

Change-In-Control Severance Agreements

Prior to the merger of the NYSE and Archipelago, Archipelago had entered into employment or change-in-control severance agreements with each of Messrs. Putnam, Chai and O'Hara, who are now president and co-chief operating officer, executive vice president and chief financial officer, and, prior to Mr. O'Hara's resignation effective April 12, 2006, executive vice president and co-general counsel of NYSE Group, respectively.

On December 30, 2005, Archipelago entered into modification agreements, which modified certain payments and vesting that would have otherwise occurred in 2006 following certain terminations after the completion of the merger of the NYSE and Archipelago. The modification agreements were entered into in order to help ensure (i) the executive officers would remain with the combined company following the merger, (ii) compliance with Section 409A of the Internal Revenue Code (which governs the taxation of arrangements that provide for the deferral of compensation) and (iii) that certain significant tax-related cost savings for the combined company were achieved. In addition, the agreements helped to harmonize the compensation structure applicable to Archipelago executives after the closing of the merger with the compensation structure applicable to NYSE executives. The NYSE consented to the execution of these modification agreements.

Under the modification agreements, on December 30, 2005, (i) each of the Archipelago executive officers received a cash payment in lieu of the cash severance amount otherwise payable pursuant to the executive officer's employment agreement or change-in-control severance agreement, as applicable, and (ii) each of their Archipelago restricted stock units fully vested in lieu of the accelerated vesting otherwise provided under such equity awards. In addition, the modification agreements provided that, immediately prior to the closing of the merger, up to 75% of the unvested stock options held by each of the executive officers would vest.

239

In the case of Mr. O'Hara, the remainder of his stock options vested upon his termination of employment in accordance with the terms of his change in control severance agreement.

The table below sets forth the amounts provided by the modification agreements:

	Cash Severance ($)	RSUs Vesting	Options Vesting
Gerald D. Putnam	7,875,000	135,893	303,234
Nelson Chai	2,250,000	52,906	87,778
Kevin J.P. O'Hara	2,250,000	52,906	87,778

NYSE Group Plans

NYSE Group, Inc. 2006 Stock Incentive Plan

Generally. In order to properly reward and incentivize NYSE Group officers, employees and outside directors, and as is customary for for-profit, public companies, NYSE Group adopted and its stockholders approved the NYSE Group, Inc. 2006 Stock Incentive Plan. The purpose of the plan is to enhance NYSE Group's profitability and value for the benefit of stockholders by enabling it to offer equity based incentives to its officers and employees and those of its subsidiaries in order to attract, retain and reward such individuals, while strengthening the mutuality of interests between those individuals and its stockholders. Officers and employees of NYSE Regulation do not participate in the NYSE Group, Inc. 2006 Stock Incentive Plan but instead participate in a cash incentive plan.

Administration of NYSE Group, Inc. 2006 Stock Incentive Plan. The human resources & compensation committee of the NYSE Group board of directors administers the NYSE Group, Inc. 2006 Stock Incentive Plan and selects the individuals who are eligible to participate in the plan. With respect to the application of the plan to non-employee directors, NYSE Group's board of directors is expected to serve as the "Committee" and will administer the plan with respect to those directors. The NYSE Group, Inc. 2006 Stock Incentive Plan permits the Committee to grant stock options (non-qualified and incentive stock options), stock appreciation rights, restricted stock, performance shares and other stock-based awards (including, without limitation, restricted stock units and deferred stock units) to certain eligible employees and non-employee directors, as determined by the Committee.

Shares Reserved Under the NYSE Group, Inc. 2006 Stock Incentive Plan. Up to 11,500,000 shares of NYSE Group common stock may be issued under the NYSE Group, Inc. 2006 Stock Incentive Plan (subject to adjustment to reflect certain transactions and events specified in the plan). The plan's share reserve includes 3,000,000 shares of NYSE Group common stock for issuance to NYSE employees in connection with the merger. If any award granted under the plan expires, terminates or is canceled without having been exercised in full, the number of shares underlying such unexercised award will again become available for awards under the plan.

The human resources & compensation committee has discretion to delegate all or a portion of its authority under the NYSE Group, Inc. 2006 Stock Incentive Plan and also determines the terms and conditions of the awards at the time of grant in accordance with the terms of the plan.

Merger Transaction Restricted Stock Unit Awards. The Committee granted restricted stock unit awards to eligible non-regulatory employees of the NYSE and to certain employees of SIAC under the NYSE Group, Inc. 2006 Stock Incentive Plan in connection with the merger. These awards were made from the portion of the plan's share reserve authorized by the merger agreement for grants to NYSE and subsidiary employees upon completion of the merger. Each restricted stock unit award vests as follows: 50% of the award vested at the time of the grant, another 25% of the award vests one year after the grant date, and the remaining 25% of the award vests two years after the grant date. However, no shares covered by the vested portion of any restricted stock unit award will be delivered until the third anniversary of the grant date, unless otherwise determined by the human resources & compensation committee. John A. Thain,

240

who is NYSE Group's chief executive officer, did not participate in this initial grant of equity awards under the Stock Incentive Plan.

Internal Revenue Code Section 162(m) and Transition Rule. The provisions of Section 162(m) of the Internal Revenue Code generally disallow a tax deduction to a publicly traded company for compensation in excess of $1,000,000 paid to its chief executive officer or any of its other four most highly compensated executive officers in any fiscal year, unless the plan and awards pursuant to which any portion of the compensation is paid meet certain requirements. Certain exceptions apply in the case of plans adopted by a private company that subsequently becomes publicly traded.

The NYSE Group, Inc. 2006 Stock Incentive Plan is intended to constitute a plan described in Treasury Regulation Section 1.162-27(f)(1), pursuant to which the deduction limits under Section 162(m) of the Internal Revenue Code do not apply during the applicable transition period. In general, the transition period ends upon the earliest of: (i) the expiration of the plan (i.e., 10 years after the date the plan is approved by stockholders); (ii) the material modification of the plan; (iii) the issuance of all available stock under the plan; or (iv) the first stockholder meeting at which directors are to be elected that occurs after December 31, 2007.

Section 409A of the Internal Revenue Code. Section 409A of the Internal Revenue Code, enacted by Congress in the American Jobs Creation Act of 2004, imposes an additional 20% income tax and interest on payments of deferred compensation to recipients that fail to meet certain payment and distribution requirements of Section 409A. The plan contains provisions that would allow NYSE Group to adjust payments under award grants to comply with Section 409A. There is no penalty imposed on NYSE Group for failure to comply with the payment and distribution requirements of Section 409A.

NYSE Group, Inc. 2006 Annual Performance Bonus Plan

NYSE Group's employees are eligible to participate in the NYSE Group, Inc. 2006 Annual Performance Bonus Plan. Employees hired between January and November in any fiscal year are eligible to participate in the plan in their year of hire. Employees hired in December are eligible to participate in the plan in the following year. Awards are completely discretionary and are paid in cash. The bonus, if any, is paid in January of the following year. While employees of NYSE Regulation are eligible to participate in this plan, their performance will be measured against the performance of NYSE Regulation, their particular division or department, and their own individual performance.

Discretionary Pool

In addition to the NYSE Group, Inc. 2006 Stock Incentive Plan, NYSE Group's chief executive officer will have the authority to grant awards of shares of NYSE Group common stock to its officers and employees and the officers and employees of NYSE Group's subsidiaries, other than employees of NYSE Regulation, in his discretion and based on individual employee discretionary award guidelines or limits approved by NYSE Group's human resources & compensation committee. This discretionary pool of 50,000 shares of NYSE Group's common stock will primarily be used for performance awards for individuals who may not normally be eligible to participate in the NYSE Group, Inc. 2006 Stock Incentive Plan based on managerial level and will give the chief executive officer the flexibility to reward officers and employees as he considers appropriate.

NYSE Compensation Plans

Generally, these plans were adopted by NYSE prior to its merger with Archipelago and now are maintained for the potential benefit of certain officers and employees of NYSE Group, NYSE Market, and NYSE Regulation, except as specifically noted otherwise.

241

The Retirement Plan

The NYSE sponsors the Retirement Plan for Eligible Employees of the NYSE (the "Retirement Plan"). As noted below, the Retirement Plan was frozen as of March 31, 2006. The Retirement Plan is a funded, tax-qualified, non contributory defined benefit pension plan that covers NYSE employees generally, but does not cover any of the named executives other than Ms. Kinney. The NYSE pays the entire cost of plan benefits. For employees hired before June 30, 2002, benefits under the Retirement Plan are based on a set percentage of the participant's annual base salary during each year of employment, subject to certain alternative calculations to mirror a final average compensation plan. Since 1989, that percentage has been 2.35%. Employees that were employed by the NYSE on or before February 17, 1998 receive an additional benefit equal to $100 for each year of service before January 1, 1981. For employees hired after June 30, 2002, benefits are calculated as follows: (1) 1.25% of final average compensation (i.e., average annual compensation during an employee's best five years) ("FAC") up to the average social security wage base ($46,200 in 2005), plus (2) 1.45% of final average compensation (i.e., average annual compensation during an employee's best five years) in excess of the average social security wage base, times (3) an employee's years of plan participation. The amount of annual compensation that may be considered in calculating benefits under the Retirement Plan is limited by law. In 2006, the limit is $220,000.

Normal retirement age under the plan is age 65. However, employees can retire and receive a reduced benefit at any time after they reach age 55. Employees become vested in their benefits upon completion of five years of service with the NYSE.

The estimated annual benefits payable from the Retirement Plan in the form of a life annuity commencing at normal retirement age (age 65) for the named executive officers hired prior to July 1, 2002 are as follows: $164,000 for Ms. Kinney. This amounts assumes future salary will be equal to the amounts earned in 2005.

Effective March 31, 2006, the Retirement Plan was frozen. Accrued benefits will continue to vest and will be paid according to the existing plan terms. No additional compensation or service credit will be awarded after March 31, 2006. Effective April 1, 2006, the Retirement Accumulation Plan described below was introduced.

Retirement Accumulation Plan

Effective April 1, 2006 for NYSE employees, a new employer funded defined contribution Retirement Accumulation Plan account was established in the Savings Plan (as described below).

Employees are eligible to receive a Retirement Accumulation Plan contribution beginning as of the later of April 1, 2006 or the first day of the month following the completion of the six-month eligibility requirement with the NYSE. Any service completed prior to April 1, 2006 will count toward determining eligibility for the new employer contribution.

To receive a contribution, an employee must be actively employed on December 31 of the plan year for which the Retirement Accumulation Plan contribution is made. The plan year is a calendar year (January 1 - December 31). However, if employment ends during the plan year due to death, retirement (termination of employment on or after age 55) or disability, the employee (or his/her beneficiary) is eligible to receive a contribution for that year based on the employee's age at the date of the event and the employee's base salary earned during the plan year.

NYSE Group will make annual contributions to this account based on the employee's age on December 31 and the employee's base salary earned during each plan year he/she is eligible for the plan. Since this new account became effective April 1, 2006, the first year's contribution will be calculated using base salary earned from April 1 to December 31, 2006.

242

The employer contribution amounts range from 3% to 6% of base salary depending on the employee's age according to the following schedule:

Age as of December 31		Contribution Percentage
Less than 35		3%
35 to 44		4%
45 to 54		5%
55 and over		6%

An employee will be fully vested in his/her Retirement Accumulation Plan contribution account:

•: after completion of five years of service with the NYSE, or
•: at age 55, regardless of years of service.

Service with the NYSE completed before and after April 1, 2006, will count toward vesting.

Since the Retirement Accumulation Plan is an account in the Savings Plan, the amounts credited to this account will be invested automatically in the investment options employees have elected for contributions under the Savings Plan.

Supplemental Executive Retirement Plan

The NYSE maintains a SERP for its employees who earn salary above a specified threshold ($184,442 in 2006) to supplement benefits under the Retirement Plan. As noted below, the SERP was frozen as of March 31, 2006. The SERP provides a base benefit to participants who have completed 10 years of NYSE service or are employed by the NYSE until age 55 with at least 36 months of SERP participation. In general, the benefit is based upon years of service and the participant's annual average of the highest 60 consecutive months of salary (plus, for senior officers, two-thirds of the bonus, not to exceed annual salary). Vested benefits do not become payable until the later of age 55 or the date of retirement. Generally, the benefit under the SERP is offset by benefits paid under the Retirement Plan and social security benefits and is further reduced if benefit payments commence prior to age 60. Participants may elect to receive their account balances in a lump sum distribution for those employees who were 55 or older and had 10 or more years of service as of December 31, 2004. Effective March 31, 2006, the SERP was frozen. Accrued benefits will continue to vest and will be paid according to the existing plan terms. No additional compensation or service credits will be awarded after March 31, 2006.

Employee Savings Plans

The NYSE sponsors two tax-qualified defined contribution plans, which are substantially similar (the "Savings Plans"). The New York Stock Exchange and Subsidiary Companies Employee Savings Plan covers salaried employees, and the New York Stock Exchange and Subsidiary Companies Operations Level Employee Savings Plan covers employees who are subject to a collective bargaining agreement.

Under the Savings Plans, which are tax-qualified retirement savings plans (401(k) plans), participating employees may contribute up to 25% of their base salaries into their Savings Plan accounts, on a pre-tax or after-tax basis, or both, subject to limitations under the Internal Revenue Code on the annual amount of contributions that participants may make and the amount of annual compensation that may be taken into account in computing benefits under the Savings Plan. The NYSE matches the first 6% of base salaries that employees contribute to the plan. Participants are immediately vested in all contributions and all earnings or loss on those contributions.

Effective January 1, 2006, matching contributions for new employees will vest at the rate of 20% per year for the first five years of recognized service.

243

Supplemental Executive Savings Plan

The NYSE maintains a SESP to provide deferred compensation opportunities to employees who earn compensation over the limit set by the Internal Revenue Code, including certain named executive officers, to supplement benefits under the Savings Plan that are subject to limitations under the Internal Revenue Code, as well as to permit additional deferrals.

Generally, employees are eligible to participate in the SESP if their base salary exceeds the Internal Revenue Service limit on annual contributions to a qualified savings plan ($44,000 in 2006) divided by 0.31. A participant's account is also credited with earnings based on a measurement alternative selected by the participant from among specified alternatives. Participants may elect to receive their account balances in a lump sum distribution or annual installments following termination of employment. The SESP continues to be under review for compliance with Internal Revenue Service Section 409(A). If the participant elects an installment payout, the account is credited with earnings based on a measurement alternative selected by the participant from among a choice of funds.

The SESP is divided into three different plans: SESP A, SESP B, and SESP C. Participation in one, two, or all three of these plans depends on how much the employees earn and how much they contribute to the SESP.

SESP A. This plan is intended to be an excess plan, which allows employees to defer a percentage of base salary up to $220,000 (in 2006) which cannot be contributed to the qualified savings plan because of the $44,000 Internal Revenue Service contribution limit.

SESP B. Employees are eligible to contribute to SESP B if their annual salary exceeds $220,000 (in 2006). This plan is also intended to be an excess plan, and it generally allows employees to defer up to 25% of base salary over $220,000 on a before-tax basis. The NYSE matches the first 6% of base salary that employees contribute to the plan.

SESP C. Employees are eligible to contribute to SESP C if their annual salary exceeds $220,000 (in 2006). This plan allows employees to contribute more than 25% of their base salary on a before-tax basis.

Participants prior to January 1, 2006 were always 100% vested in their pre-tax contributions, matching contributions by the NYSE and any earnings or losses thereon.

Effective January 1, 2006, matching contributions for new employees will vest at the rate of 20% per year for the first five years of recognized service.

The NYSE also maintains plans permitting senior officers and above to defer amounts otherwise paid to them as bonus. There is no NYSE match under these other plans.

Capital Accumulation Plan

The NYSE sponsored a Capital Accumulation Plan ("CAP") for designated senior executives through the end of 2003. Effective January 1, 2004, the Capital Accumulation Plan was frozen, and no further credits have been made for services performed after December 31, 2003. Existing awards will continue to vest in accordance with the plan, and will be distributed upon termination of employment. The plan provided supplemental retirement benefits to a select group of management and highly compensated employees of the NYSE who were designated as eligible to participate in the plan by the human resources & compensation committee of the NYSE board of directors. The plan is "unfunded" and is not intended to qualify under Section 401(a) of the Internal Revenue Code.

Historically under the CAP, each year, participating executives were credited with an amount based upon a percentage of their Annual Bonus Plan award. These awards vest, for each executive, between the ages of 55 and 60, and are transferred into a Rabbi Trust as they vest. Unvested CAP amounts earn interest based upon the 10-year Treasury Bond rate as of December 31 of the prior year. Participants may elect to

244

receive their vested account balances in a lump sum distribution or annual installments following termination of employment. If the participant elects an installment payout, the account is credited with earnings based on a measurement alternative selected by the participant from among a choice of funds. Awards are included as compensation expense in the year awarded and any related interest is included in compensation expense in the year earned.

Long-Term Incentive Deferral Plan

The NYSE sponsored a Long-Term Incentive Deferral Plan for designated senior executives through the end of fiscal year 2000. The plan permitted eligible executives to defer receipt of their long-term performance awards. Effective May 1, 2001, the Long-Term Incentive Deferral Plan was frozen. A few executives have deferred balances under this plan that will be paid upon their termination or retirement. Participants may elect to receive their vested account balances in a lump sum distribution or annual installments following termination of employment. If the participant elects an installment payout, the account is credited with earnings based on a measurement alternative selected by the participant from among a choice of funds.

ICP Award Deferral Plan

The ICP Award Deferral Plan permits senior officers of the NYSE to defer receipt of their bonuses under the Annual Bonus Plan. Participants may elect to receive their vested account balances in a lump sum distribution or annual installments following termination of employment. If the participant elects an installment payout, the account is credited with earnings based on a measurement alternative selected by the participant from among a choice of funds.

Severance Plans

All employees of the NYSE (other than those covered by a collective bargaining agreement or those who are non-expatriate foreign employees) are eligible to participate in the Severance Pay Plan. The Severance Pay Plan provides for basic and enhanced severance benefits upon certain terminations of employment. Basic severance benefits are equal to two weeks of an employee's base salary, less any other severance payments the employee receives from the NYSE. Managerial/professional employees are eligible for enhanced severance benefits. Enhanced severance is generally calculated at two weeks of base pay per year of service up to a maximum of 52 weeks, less any other severance the employee receives from the NYSE.

All severance benefits are paid in equal installments in accordance with the NYSE's regular payroll practices. Payment of enhanced severance benefits is conditioned upon the employee's execution of a release of claims in favor of the NYSE and its related entities.

Archipelago Plans

NYSE Group assumed the Archipelago plans in connection with the merger of the NYSE and Archipelago, with NYSE Group common stock being substituted on a one-for-one basis for any Archipelago common stock as the underlying security of any grants under the plans. In the merger, subject to certain vesting accelerations, all outstanding options on Archipelago common stock and restricted stock units issued under the Archipelago plans prior to the merger were converted to options on NYSE Group common stock and NYSE Group restricted stock units, respectively.

SELECTED HISTORICAL FINANCIAL DATA OF NYSE GROUP

NYSE Group is a Delaware corporation formed for the purpose of consummating the business combination of the NYSE and Archipelago, which was completed on March 7, 2006. The merger of the NYSE and Archipelago has been treated as a purchase business combination for accounting purposes, with the NYSE designated as the acquirer. As such, the historical financial statements of the NYSE have become the historical financial statements of NYSE Group.

(1): In September 2005, Archipelago completed the acquisition of PCX Holdings and its subsidiaries for a total purchase price of approximately $94.0 million consisting of a $90.9 million cash payment to PCX Holdings stockholders and certain employees of PCX Holdings and its subsidiaries, and approximately $3.1 million of direct costs incurred by Archipelago as part of this acquisition. The results of operations of PCX Holdings have been included in Archipelago's results of operations since October 1, 2005.
(2): On August 11, 2004, prior to the consummation of its initial public offering, Archipelago Holdings L.L.C. converted from a Delaware limited liability company to a Delaware corporation, Archipelago Holdings, Inc.
(3): On March 15, 2002, Archipelago completed a merger with REDIBook ECN L.L.C., a competing ECN, as a result of which Archipelago significantly increased its trading volumes in Nasdaq-listed securities.
(4): Archipelago engages in a significant amount of business with related parties in the ordinary course of its business. For a discussion of Archipelago's related-party transactions, see Note 10 to Archipelago's consolidated financial statements included elsewhere in this prospectus.
(5): Archipelago pays Section 31 fees to the SEC based on fee schedules determined by the SEC and, in turn, collects activity assessment fees from equity trading permit and option trading permit holders trading on ArcaEx and the Pacific Exchange, respectively. Activity assessment fees received are included in cash and cash equivalents at the time of receipt, and, as required by law, the amount due to the SEC is recorded as an accrued liability and remitted semiannually. Following the September 2005 acquisition of PCX Holdings, activity assessment fee revenue and Section 31 fee expense are

253

presented gross in Archipelago's statement of operations. These fees have had no impact on Archipelago's consolidated statement of operations.

(6): Following the launch of ArcaEx in March 2002, Archipelago began earning revenues from market data fees based on the level of trading activity on ArcaEx. As the operator of ArcaEx, Archipelago became eligible to participate in the sale of market data to, and the receipt of market data fees from, centralized aggregators of this information.
(7): In January 2000, Archipelago implemented an equity entitlement program under which participating customers became eligible to earn "equity entitlements" based on the volume of order flow on Archipelago's trading platforms. Equity entitlements were converted into Class B shares of Archipelago Holdings L.L.C. without additional consideration. These shares were converted into shares of Archipelago common stock in the conversion of Archipelago Holdings L.L.C. into Archipelago Holdings, Inc.
(8): In April 2002, to enhance the liquidity of its system, Archipelago began to pay a small fee per share, referred to as "liquidity payments," to participants that post certain buy and sell orders on the Archipelago system when the quote is executed against by other participants purchasing and selling internally on the Archipelago system. Archipelago generally does not pay these fees for orders posted on NYSE-listed securities.
(9): Archipelago undertook self-clearing initiatives of its routing broker and introducing broker businesses. Effective in January 2005, Archipelago Securities Inc. began to clear trades it routed to other market centers for execution. In addition, effective in July 2004, Archipelago Securities, Inc. began to clear trades effected by non-ETP broker-dealer customers accessing ArcaEx through Archipelago Trading Services. In addition, due to the lower percentage of orders routed out to other market centers, Archipelago's number of trades subject to clearing costs has decreased.
(10): In connection with its merger with the NYSE, Archipelago incurred legal, banking, regulatory and other fees in 2005. In addition, Archipelago incurred certain executive compensation expenses as a result of the acceleration of payments to, and vesting of restricted stock units of, Archipelago officers in 2005.
(11): As a limited liability company, all income taxes were paid by the members of Archipelago. As a corporation, Archipelago is responsible for the payment of all U.S. federal, state and local corporate income taxes.
(12): As part of a proposed rule change filed by the Pacific Exchange with the SEC, Archipelago undertook to divest Wave Securities L.L.C., a wholly owned subsidiary of Archipelago providing agency brokerage services. The results of operations and financial position of Wave Securities are presented as discontinued operations in the consolidated financial statements. All historical periods presented have been restated to reflect such presentation. Archipelago completed the sale of Wave Securities on March 3, 2006.
(13): In August 2004, in connection with its initial public offering, Archipelago converted 16,793,637 Class A preferred shares of Archipelago (sold to GAP Archa Holdings, L.L.C., an affiliate of General Atlantic, on November 12, 2003 for total consideration of $50.0 million) into 4,449,268 shares of Archipelago common stock. Included in this conversion was the issuance of 717,349 shares of common stock attributable to a $9.6 million beneficial conversion feature included in the previously issued redeemable preferred interest.
(14): In August 2004, in connection with Archipelago's reorganization, the members of Archipelago Holdings L.L.C. received 0.222222 shares of Archipelago common stock for each membership interest held by the member in Archipelago Holdings L.L.C. The weighted average number of shares used in

254

the basic and diluted earnings per share computations gives retroactive effect to this 4.5-for-1 reverse stock split.

(15): As approved by the board of managers of Archipelago Holdings L.L.C. on July 16, 2004, Archipelago Holdings L.L.C. made a cash distribution to its members immediately prior to the conversion transaction. The cash distribution provided funds to the members to permit them to pay taxes that the members owe for their share of Archipelago's profits in 2004 as a limited liability company through the date of the conversion transaction, calculated primarily based on the highest federal and state income tax rate applicable for tax withholding purposes to an individual. The cash distribution was approximately $24.6 million and resulted in a corresponding reduction to cash and cash equivalents. As used in this discussion, the term "members" refers to the former owners of Archipelago Holdings L.L.C.
(16): In August 2004, Archipelago completed its initial public offering and sold 6,325,000 shares of Archipelago common stock at $11.50 per share. Archipelago received net proceeds of $67.6 million and incurred approximately $6.8 million in expenses in connection with its initial public offering.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF NYSE GROUP

The following discussion of the NYSE Group's financial condition and results of operations should be read in conjunction with the consolidated financial statements of the NYSE Group and the notes thereto included in this document. The following discussion contains forward-looking statements. Actual results could differ materially from the results discussed in the forward-looking statements. See "Risk Factors" and "Forward-Looking Statements."

Overview

NYSE Group is a holding company that, through its subsidiaries, operates two securities exchanges: the NYSE and NYSE Arca. NYSE is a leading provider of securities listing, trading and market data products and services. NYSE Group was formed in connection with the merger of the NYSE and Archipelago, which was completed on March 7, 2006. As of that date, the NYSE and Archipelago became wholly owned subsidiaries of NYSE Group. As such, the historical financial statements of the NYSE have become the historical financial statements of NYSE Group.

NYSE Group was organized on May 2, 2005. As of December 31, 2005 and up until March 7, 2006, NYSE Group had no assets (other than $200 that it received on December 29, 2005 from the sale of one share of its common stock to each of the NYSE and Archipelago) and had not conducted any material activities other than those incident to its formation. On March 7, 2006, upon the completion of the merger of the NYSE and Archipelago, NYSE Group became the parent company of the NYSE and Archipelago.

Business Development

NYSE/Archipelago Merger

On April 20, 2005, the NYSE entered into a definitive merger agreement with Archipelago, pursuant to which the NYSE and Archipelago agreed to combine their businesses and become wholly owned subsidiaries of NYSE Group, a newly-created, for profit and publicly-traded holding company. The merger closed on March 7, 2006. As of that date, the NYSE and Archipelago became wholly owned subsidiaries of NYSE Group. NYSE Group common stock is listed on the NYSE and is traded under the symbol "NYX."

In the merger, each NYSE member received in exchange for its NYSE membership $300,000 in cash and 80,177 shares of NYSE Group common stock. In addition, a cash dividend of $70,571 was declared and paid to each holder of record of a NYSE membership as of March 6, 2006. In the merger, the NYSE members had the opportunity to make either a cash election to increase the cash portion (and decrease the stock portion) of their merger consideration, or a stock election to increase the stock portion (and decrease the cash portion) of their merger consideration. These elections were subject to proration. The aggregate number of shares of NYSE Group common stock issued to all of the NYSE members in the merger, together with the aggregate number of shares reserved for issuance to NYSE employees, equaled approximately 70% of the NYSE Group common stock issued and outstanding at the closing of the merger, or approximately 109.5 million shares, on a diluted basis.

In the merger: (i) each share of the issued and outstanding shares of Archipelago's common stock was converted automatically into the right to receive one share of NYSE Group common stock; (ii) all outstanding stock options of Archipelago, whether vested or unvested, converted into options to purchase an equivalent number of shares of NYSE Group common stock; and (iii) all outstanding restricted stock units of Archipelago converted into an equal number of restricted stock units of NYSE Group common stock. The aggregate number of shares (including shares underlying stock options and restricted stock units) received by Archipelago stockholders, equaled approximately 30% of the issued and outstanding shares of NYSE Group common stock at the closing of the merger, or approximately 46.0 million shares.

256

As a result of the merger, NYSE Group expects to achieve operational synergies resulting from the consolidation of capabilities and elimination of redundancies, and to achieve greater efficiencies from increased scale, market integration, more automation and for-profit structure. NYSE Group has identified cost saving opportunities in a number of areas, including hiring freezes and headcount reductions, the elimination of overlaps in technology, marketing, occupancy, and general and administrative costs, and increased efficiencies in its general business processes.

Selling Shareholder Offering

On May 10, 2006, NYSE Group completed a selling shareholder offering of 28.75 million shares of common stock at $61.50 per share, for which NYSE Group received no proceeds.

Operating Data

NYSE Group's revenues are affected by many factors, including the number of companies listed on the NYSE and NYSE Arca (both new and continuing), corporate actions by these companies (for example stock splits and mergers), trading activity, demand for data processing, and demand for market information. The following table presents selected operating data for the periods presented. A description of the manner in which the NYSE and NYSE Arca calculate their trading volumes and other operating measures is set forth below.

Sources of Revenues

Activity Assessment Fees

NYSE Group pays SEC fees pursuant to Section 31 of the Exchange Act. These Section 31 fees are designed to recover the costs to the government of supervision and regulation of securities markets and securities professionals. NYSE Group, in turn, collects activity assessment fees from organizations executing trades on the NYSE and NYSE Arca, and recognizes these amounts when invoiced. Fees received are included in cash at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as an accrued liability until paid. The activity assessment fees are

258

designed so that they are equal to the Section 31 fees. As a result, neither the size of Section 31 fees nor the size of activity assessment fees has an impact on NYSE Group's net income.

Transaction Fees

On the NYSE, trading fees are paid by member organizations based on their trading activity. Fees are assessed on a per share basis for trading in equity securities. The fees are applicable to all transactions that take place on the NYSE, and the fee amounts vary, based on the size and type of trade that is consummated. There is no fee for small electronic trades. All members and member organizations pay trading fees except "$2 brokers" (who, by definition, effect transactions only for other member organizations) and specialists. There are two caps that apply to the trading fees (other than fees for trading ETFs), and member organizations pay the lesser of these two fee caps on a monthly basis. The first cap is a maximum fixed dollar amount of $600,000 per month. The second is a variable cap that is equal to 2% of the net commissions that a member organization earns on the trades it executes on the trading floor. As a result of these caps, fluctuations in trading volumes, regardless of direction or magnitude, do not have a significant impact on NYSE Group's trading fees.

On NYSE Arca, trading fees are charged to customers for trade execution of equity securities and equity options. NYSE Arca earns transaction fees for (i) customer orders of equity securities matched internally on NYSE Arca, as well as for customer orders routed out, and (ii) customer orders of equity options traded or cleared through NYSE Arca.

For equity securities, NYSE Arca charges a per share fee (denominated in tenths of a cent per share) to each customer that executes against a buy order or sell order posted internally. NYSE Arca refers to these customers when they purchase or sell securities as "liquidity takers," as they removed liquidity from NYSE Arca. A liquidity taker may be either a purchaser or a seller, and is distinguished from a "liquidity provider" generally by the type of buy order or sell order it posts on NYSE Arca. NYSE Arca also charges a per share fee (denominated in tenths of a cent per share) to customers whose orders of equity securities are routed out to an external market center displaying the best buy order or sell order in the market for a particular security.

On June 30, 2006, NYSE Group announced transaction-pricing changes for NYSE listed equities and NYSE Arca options, effective August 1, 2006. The new pricing includes, but is not limited to, the following changes:

•: Transaction fees on NYSE-listed equities will be based on a fixed rate of 0.00025 per share rather than the current variable fee schedule.
•: The monthly cap, referenced above on trading NYSE-listed cash equities, will be increased to $750,000 from $600,000.
•: The cap equal to 2% of net commissions for trading on the NYSE will be eliminated.
•: Free system orders on all NYSE-listed equities transactions will also be eliminated (fees for ETF system orders under 5,100 shares will continue to be waived).
•: Specialists will not incur transaction fees for trading ETFs.

The pricing structures of the NYSE and NYSE Arca continue to be examined as part of a broad strategic review of NYSE Group's opportunities for revenue growth and efficiency improvement and to better capture value for the services rendered by aligning more closely transaction revenue with executed volume, product expansion and new product development. Transaction fees that NYSE Group earns in the future could also depend on the outcome of certain regulations and rule changes, such as Regulation NMS.

Listing Fees

Companies pay listing fees when they initially list on the NYSE or NYSE Arca, and annually thereafter. Listing fees consist of two components: original listing fees and other corporate action related fees. Original listing fees, subject to a minimum and maximum amount, are based on the number of shares that the company initially lists with the NYSE or NYSE Arca. Other corporate action related fees are paid by listed companies in connection with corporate actions involving the issuance of new shares to be listed on the NYSE or NYSE Arca, such as stock splits, rights issues, sales of additional securities, and mergers and acquisitions, which are subject to a minimum and maximum fee. Annual fees are charged based on the number of outstanding shares of the listed company at the end of the previous year. These fees are recognized on a pro-rata basis over the calendar year. Original listing fees are recognized on a straight-line basis over estimated service periods of 10 years for the NYSE and 5 years for NYSE Arca. Unamortized balances are recorded as deferred revenue on the consolidated statements of financial condition.

Data Processing Fees

SIAC charges data processing fees to customers other than NYSE Group (fees charged to NYSE Group are eliminated in consolidation) for communication services, data processing operations and systems development functions. SIAC operates on a cost recovery model driven by its customers' demands. Under this model, any increase or decrease in SIAC's operating expenses results in a corresponding change in its revenues. In addition, SIAC earns revenues through its subsidiary, Sector, which offers an array of communications and data processing services, primarily to the broker-dealer community.

Market Data Fees

NYSE Group collects market information fees principally for consortium-based data products and, to a lesser extent, for NYSE proprietary data products. Consortium-based data fees are determined by securities industry plans. Consortium-based data revenues that coordinated market data distribution generates (net of joint processing and administration costs) are distributed to participating markets on the basis of their respective number of trades. Last sale prices and quotes in NYSE-listed securities are disseminated through Tape A, which constitutes the majority of the NYSE's revenues from consortium-based market data revenues. NYSE Group also receives a share of the revenues from Tape B and Tape C, which represents data related to trading of certain securities that are listed on Nasdaq, AMEX, and other regional exchanges, including ETFs. These revenues are influenced by demand for the data by professional and non-professional subscribers, as well as the NYSE Group's share of trades. In addition, NYSE Group receives fees for television broadcasts, vendor access and other usage fees related to per quote or per trade data. NYSE Group proprietary products make available market data covering activity that takes place solely on the NYSE and NYSE Arca's markets, independent of activity on other markets.

Regulatory Fees

Regulatory fees are principally comprised of member firm regulation fees and market surveillance fees collected by NYSE Group. Member firm regulation fees are based on member organizations' gross revenues, as reported in their FOCUS filing with the NYSE, and assessed on a six-month lag. Market surveillance fees are charged to specialists and floor brokers to recover some of the costs of overseeing trading on the NYSE floor. Other regulatory fees include revenue from registration of branch offices, registered individuals and specialists, as well as fees for certain licensing examinations necessary to operate in the securities industry.

Licensing, Facility and Other Fees

On January 4, 2006, the NYSE completed a modified Dutch auction, as a result of which it sold 1,274 trading licenses at an annualized price of $49,290 per license, subject to SEC approval of applicable NYSE

260

rules, which approval was obtained on February 27, 2006. The NYSE has made available a maximum of 1,366 trading licenses, and any unsold trading licenses can be purchased at a 10% premium to the established auction price, on a pro rata basis, during the course of 2006. Currently, NYSE Group anticipates approximately $51 million in revenue from trading licenses for the period from March 8 to December 31, 2006, which is recognized on a straight-line basis over this period. There could be significant uncertainty regarding the number and price of trading licenses that will be sold in a given year, which could result in fluctuation in the amount of trading license fees that NYSE Group receives each year.

Until recently, the NYSE charged each specialist firm for both the number of post spaces occupied on the trading floor, and for each registered specialist. However, as of January 1, 2006, the NYSE introduced a new pricing structure to replace several fees that had been previously charged by the NYSE to specialists. Under this new structure, referred to as the "Specialist Trading Privilege Fee," specialists are charged an annual fee per symbol traded on the NYSE, and this fee is determined based on the consolidated average daily dollar volume of each particular symbol traded by the specialists. The NYSE charges floor brokers for each booth occupied on the trading floor, and rates vary depending on the location of the particular booth. Specialists and floor brokers also pay an annual fee for each of their clerks working on the trading floor. Fees are also charged to trading floor participants for a variety of services provided by the NYSE, including NYSE e-Broker® handheld devices, phone service, radio paging and connections to third-party market data providers.

Facility and other fees primarily comprise fees received for services provided to specialists, brokers and clerks physically located on the NYSE floor that enable them to engage in the purchase and sale of securities on the trading floor. These services include booth and post space, communication, trading analysis and technology.

Components of Expenses

Section 31 Fees

See "Management's Discussion and Analysis of Financial Condition and Results of Operations of NYSE Group—Sources of Revenues—Activity Assessment Fees" above.

Merger Expenses and Related Exit Costs

Merger expenses and related exit costs consist of severance costs, as well as legal, printing and accounting fees incurred in connection with the May 2006 selling shareholder offering of NYSE Group common stock, and other professional fees directly attributable to the merger with Archipelago.

Compensation

NYSE Group's compensation expense includes employee salaries, incentive compensation (including stock-based compensation) and related benefits expense, including pension, medical, postretirement medical, and SERP charges. Part-time help, primarily related to security personnel at the NYSE, is also recorded in this category.

Liquidity Payments

To enhance the liquidity of its system, NYSE Arca pays a small fee per share (denominated in tenths of a cent per share) to participants, referred to as "liquidity providers," that post buy orders and sell orders on NYSE Arca, when the quote is executed against, or "hit," by liquidity takers purchasing or selling securities internally on NYSE Arca.

261

Routing and Clearing

NYSE Arca incurs routing charges when NYSE Arca does not have the best buy or sell order in the market for a security that a customer is trying to buy or sell on NYSE Arca. In that case, NYSE Arca routes the customer's order to the external market center that displays the best buy order or sell order. The external market center charges NYSE Arca a fee per share (denominated in tenths of a cent per share) for routing to its system.

In addition, NYSE Arca incurs clearance, brokerage and related transaction expenses, which primarily include costs incurred in self-clearing activities, service fees paid per trade to exchanges for trade execution, and costs incurred due to erroneous trade execution.

Systems and Communications

NYSE Group's systems and communications expense includes (i) certain costs for development and maintenance of trading, regulatory and administrative systems, (ii) investments in system capacity, reliability and security and (iii) network connection with its customers and its data centers, as well as connectivity to various other market centers.

Professional Services

NYSE Group's professional services expense includes consulting charges related to various technological and operational initiatives, as well as legal and audit fees. NYSE Group's historical spending related to professional services consists principally of legal and consulting expenses. While NYSE Group is focused on reducing costs, including professional services costs, there is no guarantee that NYSE Group's professional services expenses will decline in the future. Under certain circumstances, particularly as NYSE Group pursues its business strategy, NYSE Group may be required to incur significant professional services costs, such as legal expenses.

Depreciation and Amortization

This item includes costs from depreciating fixed assets and amortizing intangible assets over their estimated useful lives. It also includes depreciation of computer hardware and capitalized software.

Occupancy

Occupancy includes costs related to NYSE Group's leased premises, as well as real estate taxes and maintenance of owned premises.

Marketing and Other

Marketing and other expenses includes advertising, printing and promotion expenses, insurance premiums, travel and entertainment expenses as well as other administrative expenses.

Regulatory Fine Income

Regulatory fine income is generated from fines levied by NYSE Regulation, which regulates and monitors the activities on NYSE Group's securities exchanges and enforces member organization compliance with applicable law and the rules of the exchanges. The frequency with which fines may be levied and their amount will vary based upon the actions of participants on the NYSE and NYSE Arca. Regulatory fines are used for regulatory purposes.

262

Segment Reporting

Subsequent to the merger of the NYSE and Archipelago, NYSE Group has operated under three reportable segments: Market, SIAC Services and Regulation. NYSE Group's segments are managed and operated as three business units and organized based on services provided to customers.

Market represents primarily the fees earned from (i) obtaining new listings and servicing existing listings on the NYSE and NYSE Arca, (ii) providing access to trade execution, (iii) distributing market information to data subscribers, and (iv) issuing trading licenses (previously membership fees).

SIAC Services provides communication and data processing operations and systems development functions to the NYSE and third-party customers.

Regulation provides regulatory services (including member firm regulation, market surveillance, enforcement, listed company compliance, and arbitration), performed by NYSE Regulation, to NYSE and NYSE Arca. Regulatory fees are paid by member organizations and are primarily assessed based upon their Gross FOCUS revenues. In addition, Regulation collects regulatory fines that are levied against members and member organizations.

Prior to the merger of the NYSE and Archipelago, the NYSE operated under two reportable segments: NYSE Market and SIAC Services. Prior to 2005, the NYSE did not maintain accounting systems that would have enabled the use of the allocation methodologies that NYSE Group is currently using. The segment information for the interim periods in the year ended December 31, 2005 have been restated. However, the related items of disclosure for the years ended December 31, 2003 and 2004 have not been restated because it is impracticable to do so. Accordingly, the comparison of results of operations for the year ended December 31, 2005 versus the year ended December 31, 2004, as well as that for the year ended December 31, 2004 versus the year ended December 31, 2003, have been presented using the two historical segments of the NYSE during those periods, and not using the three reportable segments currently used by NYSE Group.

Results of Operations

NYSE Group has treated the merger of the NYSE and Archipelago as a purchase business combination for accounting purposes, with the NYSE designated as the business and accounting acquirer. As a result, the historical results of the NYSE are the historical results of NYSE Group. The results of operations of NYSE Arca have been included in the results of operations of NYSE Group since March 8, 2006.

Consolidated Results

For the three months ended June 30, 2006, the results of operations of NYSE Group included the results of the NYSE, SIAC and the results of operations of NYSE Arca following the March 7, 2006 merger with Archipelago. For the same period a year ago, the results of operations of NYSE Group only included the results of the NYSE and SIAC.

For the three months ended June 30, 2006, NYSE Group reported revenues (excluding activity assessment fees), operating income and net income of $469.8 million, $84.0 million and $61.2 million, respectively. This compares to revenues (excluding activity assessment fees), operating income and net income of $263.0 million, $8.7 million and $13.0 million, respectively, for the three months ended June 30, 2005.

264

The $206.8 million increase in revenues (excluding activity assessment fees), $75.3 million increase in operating income and $48.2 million increase in net income for the period reflect the following principal factors:

Increased revenues. NYSE Arca's results of operations were consolidated for the three months ended June 30, 2006 and contributed revenues of $180.4 million (excluding activity assessment fees), which was the primary driver of the period-over-period increase.

Increased operating income. The period over period increase in operating income of $75.3 million was the result of NYSE Arca's contribution to operating income of $36.0 million as well as other revenue growth and overall operating efficiencies as NYSE Group continues to meet its integration goals.

Improved net income. Period over period, net income increased $48.2 million including $22.5 million related to NYSE Arca, revenue growth and overall operating efficiencies.

Transaction. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, transaction fees increased by $160.2 million, or 423.8%, primarily as a result of NYSE Arca's contribution since the completion of the merger on March 7, 2006.

Listing. The following table sets forth the revenues from listing fees calculated in accordance with U.S. generally accepted accounting principles ("as reported") and as would be reported on a basis without giving effect to U.S. generally accepted accounting principles ("billed basis"). NYSE Group believes that the presentation of billed basis revenues, as they relate to original fees, is a good indicator of current listing fee activity as billed basis information excludes the effects of recognizing revenues related to original fees over periods ranging from 5 to 10 years.

	Three months ended June 30,
	Three months ended June 30,								Percent Increase (Decrease)
	2006				2005				Percent Increase (Decrease)

Annual fees	$	66.1	$	66.1	$	62.9	$	62.9	5.1	%	5.1	%

	$	88.8	$	87.0	$	85.5	$	83.8	3.9	%	3.8	%

For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, listing fee revenue increased $3.3 million, or 3.9%, on an as reported basis.

265

Listing fees are primarily derived from annual listing fees and original listing fees. Original listing fees are deferred and recognized over the estimated service periods ranging from 5 to 10 years. The difference between the as reported revenues and the billed basis revenues is due to the amortization of listing fees in accordance with U.S. generally accepted accounting principles.

Annual listing fees totaled $66.1 million on both an as reported and billed basis for the three months ended June 30, 2006, compared with $62.9 million on both an as reported and billed basis for the three months ended June 30, 2005, an increase of 5.1%. The period over period improvement is due to the increase in aggregate shares billed at the beginning of the year, from approximately 387 billion to 408 billion, as well as new listings of shares during the year, which generate annual fees for the period of the year listed. Annual listing fees are recognized on a pro-rata basis over the calendar year.

Original listing fees amounted to $22.7 million on an as reported basis. On a billed basis, original listing fees totaled $20.9 million for the three months ended June 30, 2006, unchanged as compared to the same period a year ago.

Market Data. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, market data fees increased $14.1 million, or 30.5%, primarily from the contribution of NYSE Arca's operations, following the March 7, 2006 merger with Archipelago.

Market services provided to Regulation. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, market services provided to Regulation decreased $1.4 million, or 4.4%. These services, which include costs associated with supporting IT infrastructure, finance, human resources and other administrative functions, are provided by Market to support the operations of Regulation. The period over period decrease was primarily driven by overall cost savings initiatives.

Licensing, facility and other. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, licensing and facility fees increased $22.9 million, or 174.6%. License trading fees represented $16.0 million of the increase. Also driving the increase was the new pricing for certain facility charges implemented in January 2006. NYSE Group did not generate licensing fees in the same period a year ago.

Data processing—non-NYSE. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, data processing fees decreased $5.8 million, or 12.3%, to $41.9 million. The decline is due to reduced level of services provided to SIAC's major customers and lower revenues from the communication services of Sector.

Data processing—NYSE. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, data processing fees decreased $11.4 million, or 17.3%, to $54.4 million. These fees decreased due to cost reduction initiatives.

Regulatory Fees. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, regulatory fees increased $12.1 million, or 37.2%, to $44.7 million. For the three months ended June 30, 2006, NYSE Arca contributed regulatory fees of $2.8 million. The remaining $9.3 million increase was due to higher reported Gross FOCUS revenues ($66.1 billion compared to $47.0 billion period over period).

Regulatory services provided to Market. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, regulatory services provided to Market increased $1.6 million or 5.5%. These services, which include costs associated with surveillance, examination and enforcement with respect to Market activities, and overseeing compliance by listed companies, are provided by Regulation. The increase primarily reflects increased compensation costs for cash awards granted to Regulation employees following the merger with NYSE Arca.

(1): Market's SIAC support expense will not equal SIAC Services' revenues from Data processing—NYSE as certain fees billed to the NYSE by SIAC relate to software developed for the NYSE's internal use, and as a result a portion of these fees incurred during the application development stage has been capitalized.

267

Merger expenses and related exit costs. For the three months ended June 30, 2006, NYSE Group incurred $9.7 million in merger expenses and related exit costs consisting of severance costs ($5.8 million), legal, printing and accounting fees incurred in connection with the May 2006 selling shareholder offering of NYSE Group common stock ($2.1 million), and other professional fees ($1.8 million) directly attributable to the March 7, 2006 merger with Archipelago. NYSE Group did not incur any similar expenses in the same period a year ago.

Compensation. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, compensation was up $14.6 million, or 31.5%. The employees of NYSE Arca accounted for $15.5 million of this increase. Excluding the impact of NYSE Arca's consolidation and stock-based compensation during the three months ended June 30, 2006, compensation decreased by $4.8 million primarily due to cost savings initiatives. NYSE Group did not record any stock-based compensation in the same period a year ago.

Liquidity payments. For the three months ended June 30, 2006, NYSE Arca incurred liquidity payments of $74.8 million. NYSE Group did not incur any similar expenses in the same period a year ago.

Routing and clearing. For the three months ended June 30, 2006, NYSE Arca incurred routing and clearing fees of $23.4 million. NYSE Group did not incur any similar expenses in the same period a year ago.

Regulatory services provided to Market. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, regulatory services provided to Market increased $1.6 million or 5.5%. The increase primarily reflects increased compensation costs for cash awards granted to Regulation employees following the merger with NYSE Arca.

Systems and SIAC Support. For the three months ended June 30, 2006, compared to three months ended June 30, 2005, systems related costs decreased $4.6 million, or 6.4%. For the three months ended June 30, 2006, the operations of NYSE Arca accounted for $5.9 million of the $13.1 million of systems and communications. SIAC support costs decreased by 17.3% to $54.4 million due to structural cost effectiveness efforts, which resulted in lower data processing operations and systems development costs, lower headcount and increased utilization rates.

Professional Services. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, professional services decreased $4.1 million, or 17.1%. This decrease was primarily due to reduced legal fees and the achievement of certain integration synergies.

Depreciation and Amortization. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, depreciation and amortization increased $11.6 million, or 75.6%. The operations of NYSE Arca represented $8.9 million of the increase following the March 7, 2006 merger

268

with Archipelago. The remaining $2.7 million increase was associated with capital expenditures on technology and infrastructure.

Occupancy. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, occupancy increased $3.8 million, or 57.8%, which was primarily the result of the consolidation of NYSE Arca's operations following the completion of the March 7, 2006 merger with Archipelago.

Marketing and other. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, marketing and other expenses increased $8.3 million, or 61.7%, primarily as a result of continued increase in advertising and promotion activity, as well as higher insurance premiums and additional expenses incurred as a public company.

Compensation. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, compensation decreased $7.2 million, or 12.4%. This decrease was primarily due to cost reduction initiatives and the resulting decrease in average headcount, partially offset by $1.9 million of stock based compensation recognized for restricted stock units granted at the date of the merger with NYSE Arca.

Systems and communications. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, systems and communication expenses decreased $8.6 million, or 37.6%, to $14.2 million, primarily as a result of cost containment initiatives.

Compensation. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, compensation increased $2.7 million, or 10.2%, to $29.1 million. This increase was primarily due to $1.8 million of cash awards granted to Regulation employees at the time of the merger coupled with a modest increase in the average Regulation headcount.

270

Professional services. For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, professional services increased $1.5 million, to $1.8 million. These costs increased as newly established mandatory regulatory audits commenced during 2006.

Regulation's other operating expenses, including systems and communications, depreciation and amortization as well as marketing and general and administrative expenses were relatively stable period over period.

Regulatory Fine Income

For the three months ended June 30, 2006, compared to the three months ended June 30, 2005, fine income increased $5.0 million to $6.2 million. Regulatory fines result from actions taken by Regulation in its oversight of member organizations and accordingly may vary period over period.

Investment and Other Income, Net

The components of investment and other income, net, were as follows:

		Three months ended June 30,

		(amounts in millions)
Investment income, net		$	9.1	$	9.8
Other income			7.9		3.1

	Total	$	17.0	$	12.9

The decrease in investment income, net, is primarily attributable to a decrease in the average investment portfolio subsequent payments to the former members which is somewhat offset by the increased interest rates on NYSE Group's cash balances and investment portfolio. The increase in other income primarily relates to insurance reimbursements received which may vary period over period.

Income Taxes. The consolidated effective tax rate for the three months ended June 30, 2006 and June 30, 2005 was 38.1% and 34.3%, respectively. For the three months ended June 30, 2006, NYSE Group provided for income taxes at a 41.0% combined federal, state and local tax rate. NYSE Group's 38.1% consolidated effective rate for the three months ended June 30, 2006 reflected certain tax refunds.

Consolidated Results

For the six months ended June 30, 2006, the results of operations of NYSE Group included the results of the NYSE, SIAC and the results of operations of NYSE Arca since the March 7, 2006 merger with Archipelago. For the same period a year ago, the results of operations of NYSE Group only included the results of the NYSE and SIAC.

For the six months ended June 30, 2006, NYSE Group reported revenues (excluding activity assessment fees), operating income and net income of $785.6 million, $97.0 million and $91.5 million, respectively. This compares to revenues (excluding activity assessment fees), operating income and net income of $520.6 million, $42.4 million and $39.0 million, respectively, for the six months ended June 30, 2005.

272

The $265.0 million increase in revenues (excluding activity assessment fees), $54.6 million increase in operating income and $52.5 million increase in net income for the period reflect the following principal factors:

Increased revenues. NYSE Arca's results of operations were consolidated for the full six months ended June 30, 2006 and contributed revenues of $226.6 million (excluding activity assessment fees), which was the primary driver of the period-over-period increase.

Increased operating income. The period over period increase in operating income of $54.6 million was the result of (i) NYSE Arca's contribution to operating income of $45.8 million for the six months ended June 30, 2006 partially offset by (ii) $37.3 million of compensation expense recorded at the time of the merger following the immediate vesting of approximately 600,000 restricted stock units granted to NYSE employees, and the immediate vesting of other compensation arrangements with NYSE Regulation employees.

Improved net income. Period over period, net income increased $52.5 million primarily as a result of increased operating revenue as well as $20.9 million gain recognized on the sale of shares of DTCC common stock in March 2006.

For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, listing fee revenue increased $5.7 million, or 3.3%, on an as reported basis.

Annual listing fees totaled $132.1 million on both an as reported and billed basis for the six months ended June 30, 2006, compared with $126.4 million on both an as reported and billed basis for the six months ended June 30, 2005, an increase of 4.5%. The period over period improvement is due to the increase in aggregate shares billed at the beginning of the year, from approximately 387 billion to 408 billion, as well as new listings of shares during the year, which generate annual fees for the period of the year listed. Annual listing fees are recognized on a pro-rata basis over the calendar year.

Original listing fees amounted to $45.1 million on an as reported basis. On a billed basis, original listing fees totaled $39.6 million for the six months ended June 30, 2006 compared with $42.5 million, a 6.8% decrease, for the same period a year ago. The decrease was due to reduced new issue listings, from 73 to 53 driven primarily by a reduction in the number of new closed end fund listings which are highly interest rate sensitive.

Market Data. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, market data fees increased $18.2 million, or 20.1%, primarily from the contribution of NYSE Arca since the completion of the merger on March 7, 2006.

Market services provided to Regulation. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, Market services provided to Regulation increased $11.5 million, or 19.1%. Market provides these services, which include costs associated with supporting IT infrastructure, finance, human resources and other administrative functions to support the operations of Regulation. The increase was primarily driven by the additional investment in technology supporting Regulation and increased compensation costs for vesting of restricted stock units granted to Market employees following the merger with NYSE Arca.

Licensing, facility and other. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, licensing and facility fees increased $31.1 million, or 110.7%. License trading fees represented $20.5 million of the increase. Also driving the increase was the new pricing for certain facility charges implemented in January 2006. NYSE Group did not generate licensing fees in the same period a year ago.

(1): Market's SIAC support expense will not equal SIAC Services' revenues from Data processing—NYSE as certain fees billed to the NYSE by SIAC relate to software developed for the NYSE's internal use and as a result a portion of these fees incurred during the application development stage has been capitalized.

Merger expenses and related exit costs. For the six months ended June 30, 2006, NYSE Group incurred $12.3 million in merger expenses and related exit costs consisting of severance costs ($5.8 million), legal, printing and accounting fees incurred in connection with the completion of the merger of the NYSE and Archipelago, as well as the May 2006 selling shareholder offering of NYSE Group common stock ($4.0 million), and other professional fees ($2.5 million) directly attributable to the March 7, 2006 merger with Archipelago.

Compensation. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, compensation increased $11.2 million, or 21.3%, to $63.8 million. This increase was primarily due to the $6.7 million recognition of certain cash awards granted to NYSE employees at the time of the merger coupled with a modest increase in headcount and related increased compensation costs within Regulation.

Market services provided to Regulation. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, market services provided to Regulation increased $11.5 million, or 19.1%, to $71.1 million. The increase was primarily driven by increased compensation costs for vesting of restricted stock units granted to Market employees following the merger with NYSE Arca.

Professional services. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, professional services increased $2.0 million to $2.8 million. These costs increased as newly established mandatory regulatory audits commenced during 2006.

Regulatory Fine Income. For the six months ended June 30, 2006, compared to the six months ended June 30, 2005, fine income increased $1.2 million, or 5.4%. Regulatory fines result from actions taken by Regulation in its oversight of member organizations and accordingly may vary period over period.

Investment and Other Income, Net. The components of investment and other income, net, were as follows:

		Six months ended June 30,

		(amounts in millions)
Investment income, net		$	19.2	$	15.5
Other income			14.6		7.7

	Total	$	33.8	$	23.2

The increase in investment income, net, is primarily attributable to the increased interest rates on NYSE Group's cash balances and investment portfolio. The increase in other income relates to insurance reimbursements received which may vary period over period.

Gain on Sale of Equity Investment. On March 28, 2006, NYSE Group sold its shares of DTCC common stock for a $23.4 million cash payment. NYSE Group carried this investment at its $2.5 million cost and therefore realized a $20.9 million pre-tax gain that is included in gain on sale of equity investment in the condensed consolidated statement of income for the six months ended June 30, 2006. The after-tax impact of this gain was included in the cash dividend paid to each former NYSE member in connection with the merger of NYSE and Archipelago.

Income Taxes. The consolidated effective tax rate for the six months ended June 30, 2006 and June 30, 2005 was 38.4% and 40.0%, respectively. The decrease was primarily associated with the $20.9 million gain on sale of equity investment during 2006, which was taxed at approximately 35%, and from certain refunds.

The NYSE's operations for the year ended December 31, 2005 resulted in net income of $40.8 million compared to net income of $30.2 million for the year ended December 31, 2004. The NYSE's improved operating results were driven by a $226.3 million, or 16.1%, increase in revenues, a $27.8 million increase in Regulatory fine income, partially offset by a $223.7 million increase in expenses as compared to the year ended December 31, 2004.

For the year ended December 31, 2005, total revenues were $1,629.8 million. Revenues, excluding activity assessment fees, were $1,035.2 million compared with $1,043.7 million for the year ended December 31, 2004. The decrease of $8.5 million was driven primarily by reduced data processing fees offset by growth in many of its key businesses.

For the year ended December 31, 2005, total expenses, excluding Section 31 fees, were $1,031.4 million, compared with $1,042.5 million for the year ended December 31, 2004. Expenses,

281

excluding Section 31 fees and Archipelago merger and related exit costs, declined $37.2 million, or 3.6%, primarily due to ongoing cost reduction initiatives.

Revenues—NYSE Market

Overview. The following table sets forth the revenues attributable to NYSE Market for the year ended December 31, 2005 and 2004, as well as the percentage increase or decrease for each consolidated statements of income item for the year ended December 31, 2005, as compared to such item for the year ended December 31, 2004.

Listing Fees. The following table sets forth the revenues from listing fees calculated in accordance with U.S. generally accepted accounting principles ("as reported") and as would be reported on a basis without giving effect to U.S. generally accepted accounting principles ("billed basis"). The NYSE believes that the presentation of billed basis revenues, as they relate to original fees, is a good indicator of current listing fee activity as billed basis information excludes the effects of recognizing revenues related to original fees over 10 years.

	Year ended December 31,
	Year ended December 31,								Percent Increase (Decrease)
	2005				2004				Percent Increase (Decrease)
	As Reported		Billed Basis		As Reported		Billed Basis		As Reported		Billed Basis
	(amounts in millions)
Annual fees	$	252.2	$	252.2	$	241.3	$	241.3	4.5	%	4.5	%
Original fees		90.5		83.9		88.5		79.6	2.3	%	5.4	%

	$	342.7	$	336.1	$	329.8	$	320.9	3.9	%	4.8	%

For the year ended December 31, 2005 compared to the year ended December 31, 2004, listing fees increased $12.9 million, or 3.9%, on an as reported basis.

Listing fees are primarily derived from annual listing fees and original fees. Original listing fees are deferred and amortized over the estimated service period of 10 years. The difference between the as reported revenues and the billed basis revenues is due to the amortization of listing fees in accordance with U.S. generally accepted accounting principles.

Annual listing fees totaled $252.2 million on both an as reported and billed basis for the year ended December 31, 2005 compared with $241.3 million on both an as reported and billed basis for the year ended December 31, 2004, an increase of 4.5%. This is due to the increase in aggregate shares billed at the beginning of the year, from 355 billion to 387 billion, as well as new listings of shares during the year, which generate annual fees for the period of the year listed. Annual listing fees are recognized on a pro-rata basis over the calendar year.

282

For the year ended December 31, 2005, original fees totaled $90.5 million on an as reported basis. On a billed basis, original fees totaled $83.9 million in 2005 compared with $79.6 million in 2004, a 5.4% increase. Original listings of operating companies, closed-end funds and ETFs increased year over year from 165 to 192, which drove the increase in original fees billed.

Market Information Fees. For the year ended December 31, 2005, compared to the year ended December 31, 2004, market information fees increased $10.6 million, or 6.3%. The number of non-professional users increased by 13.4% year over year. The demand for NYSE Open Book®, one of the NYSE's proprietary data products, continued to increase, as the number of subscribers was 17.5% higher than the same period in the prior year causing NYSE Open Book® revenue to increase by 24.7% to $21.2 million. The NYSE's non-recurring revenue of $5.8 million is comprised of (i) charges for customers who had previously not reported the appropriate number of professional devices in use and (ii) an allowance for doubtful accounts reduction. In the normal course of business, the NYSE audits its customers and the number of devices they report (on which it generates its billing) and adjusts its records based on the audit results, if necessary. This can lead to both increases and decreases in current billings. Additionally, the NYSE's allowance for doubtful accounts was reduced after a review of its policy for reserving market data revenues, and based on current levels of recoveries and collections, which have improved over the past year. Somewhat offsetting the increase in market information fees was NYSE's share of Tape A trades decreasing period over period, from 90.6% to 87.5%.

Trading Fees. For the year ended December 31, 2005, compared to the year ended December 31, 2004, trading fees fell $7.8 million, or 5.0%. Although NYSE listed average daily volume was up 9.0%, current pricing structures relating to dollar caps inhibited the NYSE's ability to generate revenue growth. Partially offsetting this decline in revenue was an increase in revenue derived from ETF transactions. These revenues increased 136.3% as compared to 2004 as the trading activity increased from 236 million shares during 2004 to 926 million shares for 2005.

Regulatory Fees. For the year ended December 31, 2005, compared to the year ended December 31, 2004, regulatory fees increased $16.5 million, or 14.5%. Member regulation fees drove the increase for the year due to higher reported gross FOCUS revenues ($187.3 billion in 2005 as compared to $145.4 billion in 2004).

Facility and Equipment Fees. For the year ended December 31, 2005, facility and equipment fees were relatively flat as compared to December 31, 2004. Both the type and level of services provided to the floor were generally unchanged.

Membership Fees. For the year ended December 31, 2005, compared to the year ended December 31, 2004, annual membership fees from NYSE Market fell $1.9 million, or 23.8%. The decrease was due to fewer electronic access member renewals period over period and electronic access member prices.

Data Processing Fees—Non-NYSE. For the year ended December 31, 2005, compared to the year ended December 31, 2004, data processing fees decreased $37.8 million, or 17.1%, to $182.9 million, due to decreases in services provided to SIAC's major non-NYSE customers and lower revenues from the communication services of Sector, Inc., SIAC's subsidiary.

Data Processing Fees—NYSE. For the year ended December 31, 2005, compared to the year ended December 31, 2004, data processing fees decreased $13.3 million, or 5.0%, to $252.8 million. These fees decreased due to structural cost effectiveness efforts and continued transfer of certain lease obligations for data processing equipment from SIAC to the NYSE.

Benefits and other			91.1		100.4	(9.3	)%

	Total compensation	$	293.7	$	279.4	5.1	%

Compensation. For the year ended December 31, 2005, compared to the year ended December 31, 2004, compensation increased by $14.3 million, or 5.1%. Average headcount increased to 1,596 employees during 2005 from 1,551 in 2004 due principally to staff increases in NYSE Regulation. In addition, average salaries increased 4.9% and additional incentive awards were provided to NYSE Market employees during this period. Offsetting this increase was the impact of certain changes made to the NYSE Market employee benefit plans announced during 2005.

Systems and SIAC Support. For the year ended December 31, 2005, compared to year ended December 31, 2004, system costs increased $3.6 million, or 9.6%, as a result of additional operating leases during 2005. SIAC support decreased by 6.1% to $240.2 million due to efforts to achieve structural cost effectiveness, which reduced SIAC data processing operations and systems development costs, continued transfer of certain lease obligations for data processing equipment from SIAC to the NYSE, and reduced headcount.

Professional Services. For the year ended December 31, 2005, compared to the year ended December 31, 2004, professional services increased $1.4 million or 1.7%. Legal fees represented $24.0 million or 29.3% of total professional services, down from $28.2 million or 35.1% of total professional services for the year ended December 31, 2004. Offsetting this decline were increases in

285

consulting fees period over period due to various initiatives undertaken across the organization, including improving corporate and regulatory systems.

Depreciation and Amortization. For the year ended December 31, 2005, compared to the year ended December 31, 2004, depreciation and amortization increased $5.7 million, or 9.5% reflecting the full year impact of accelerated useful lives implemented during 2004. Capital expenditures for 2005 were consistent as compared to 2004 with continued investments in technology and infrastructure.

Occupancy. For the year ended December 31, 2005, compared to the year ended December 31, 2004, occupancy increased $1.7 million or 4.4% due to increased operating expenses.

General and Administrative. For the year ended December 31, 2005, compared to the year ended December 31, 2004, general and administrative expenses decreased $12.5 million, or 18.0%. Cost savings initiatives at the NYSE in 2005 led the reductions, consisting of decreased advertising, travel and entertainment expenses and decreased contributions to various organizations.

Archipelago Merger and Related Exit Costs. For the year ended December 31, 2005, the NYSE incurred $26.1 million in expenses related to the merger with Archipelago for which there was no comparison in 2004. These costs included $18.5 million in legal costs, $3.9 million in severance payments and $3.7 million in integration costs.

Regulatory Fine Income

For the year ended December 31, 2005, compared to the year ended December 31, 2004, regulatory fines increased from $7.6 million to $35.4 million including fines totaling $29.0 million to two member organizations. Regulatory fines result from disciplinary actions taken by NYSE Regulation in its oversight of member organizations and accordingly may vary significantly from period to period.

Expenses—SIAC Services

Overview. The following table sets forth the expenses attributable to SIAC Services for the years ended December 31, 2005 and December 31, 2004, as well as the percentage increase or decrease for each consolidated statement of income item for the year ended December 31, 2005, as compared to such item for the year ended December 31, 2004.

Benefits and other		59.9		67.8	(11.7	)%

Total compensation	$	224.2	$	248.5	(9.8	)%

Compensation. For the year ended December 31, 2005, compared to the year ended December 31, 2004, compensation decreased $24.3 million, or 9.8%, to $224.2 million due to a decrease in average headcount from 1,599 employees to 1,367. In 2004, additional expenses were incurred due to staff reductions, which were partially offset by changes made to certain benefit plans.

Systems. For the year ended December 31, 2005, compared to the year ended December 31, 2004, systems costs decreased $18.1 million, or 18.0%, to $82.7 million, primarily due to cost containment initiatives and the transfer of certain computer equipment leases to NYSE Market.

Professional Services. For the year ended December 31, 2005, compared to the year ended December 31, 2004, professional services decreased $7.1 million, or 12.4%, to $50.2 million. Lower average contract staff, from 262 to 213, and decreased temporary support for trading operations contributed to the reduction.

Depreciation and Amortization. For the year ended December 31, 2005, compared to the year ended December 31, 2004, depreciation and amortization expenses rose $2.1 million, or 5.9% year over year, to $37.7 million. This increase was due to the full year impact of accelerated useful lives, which began in December 2004 following the review of certain depreciation policies, and the continued capital expenditures in technology and infrastructure.

Occupancy. For the year ended December 31, 2005, compared to the year ended December 31, 2004, occupancy costs were relatively flat year over year, reflecting an increase of $0.3 million, or 1.0%, to $30.6 million.

General and Administrative. For the year ended December 31, 2005, compared to the year ended December 31, 2004, general and administrative expenses decreased by $2.1 million, or 14.3%, to $12.6 million. This decrease was primarily due to a loss on disposal of assets during 2004 associated with the decommissioning of services provided to SIAC's major customers, which did not occur in 2005.

Investment and Other Income, net. For the year ended December 31, 2005, compared to the year ended December 31, 2004, investment and other income increased $11.6 million to $40.8 million. Increases were driven primarily by higher investment income of $16.6 million due to the effect of the portfolio reallocation initiated in December 2004 to higher yielding and more tax-efficient securities, a more favorable interest rate environment for investments over the same period in the prior year, and realized gains of certain investments. This increase was offset by a reduction of $5.2 million in insurance

287

settlements received during 2005 as compared to 2004. Insurance proceeds received of $4.4 million in 2005 were the result of claims made for legal expenses incurred in prior years.

For the year ended December 31, 2005, compared to the year ended December 31, 2004, investment and other income increased $5.6 million, or 107.7%, to $10.8 million, primarily due to a $5.5 million insurance settlement for Sector's business claims from the events of September 11, 2001.

Income Taxes

The NYSE's consolidated effective tax rates for the years ended December 31, 2005 and December 31, 2004 were 53.0% and 28.0%, respectively. The NYSE's 2004 effective tax rate was approximately 7% less than its standard effective tax rate, due to non-taxable insurance proceeds received during the year, which decreased the effective tax rate by 4.8%, as well as tax credits received during the year, which reduced the effective tax rate by 5.7%. These credits were related to investment tax credits not previously taken and totaled $3.7 million, which had an impact on net income in 2004 of approximately $2.4 million. To the extent there are tax credits identified in the future which have not been previously taken, they will potentially reduce the provision for income taxes and increase net income. The NYSE's 2005 effective tax rate was significantly higher than its standard rate due to non-deductible merger- related expenses for litigation, which accounted for 7.1% of the rate increase and a write-down of a deferred tax asset, which accounted for 9.9% of the rate increase. This write-down was recorded following the determination by management that the deferred tax asset related to tax depreciation would not be realized. Offsetting these rate increases in 2005 was a decrease of approximately 4% related to non-taxable municipal interest income.

The following table sets forth the provision for income taxes, and the overall effective tax rate for the NYSE, on a consolidated basis, as well as for its two reportable segments—NYSE Market and SIAC Services—for the years ended December 31, 2005 and December 31, 2004.

The NYSE's operations for the year ended December 31, 2004 resulted in net income of $30.2 million, compared to net income of $60.5 million for the year ended December 31, 2003. The decrease in the NYSE's net income was driven primarily by a $16.1 million, or 1.5%, decrease in revenues, excluding activity assessment fees, a $46.0 million, or 4.6%, increase in expenses, excluding Section 31 fees, and a $3.6 million decrease in Regulatory fine income for the year ended December 31, 2004, compared to the year ended December 31, 2003.

For the year ended December 31, 2004, total revenues were $1,403.5 million. Revenues, excluding activity assessment fees, for 2004, were $1,043.7 million compared to $1,059.8 million for the year ended December 31, 2003. An increase in listing fees of $9.1 million, or 2.8%, partially offset large percentage declines in facility and equipment, regulatory fine income and membership fees and more modest percentage declines in data processing, market information and trading fees.

For the year ended December 31, 2004, total expenses, excluding Section 31 fees, were $1,042.5 million, compared to $996.5 million for the year ended December 31, 2003. Expenses, excluding

289

Section 31 fees, increased by $46.0 million, or 4.6%, primarily as a result of a $35.2 million, or 36.1%, increase in professional services expense due primarily to higher legal and consulting expense, as well as higher general and administrative expense due to additional advertising in 2004 and greater depreciation expense due to shortened estimates of certain asset lives.

Revenues—NYSE Market

Overview. The following table sets forth the revenues attributable to NYSE Market for the years ended December 31, 2004 and December 31, 2003, as well as the percentage increase or decrease for each consolidated statement of income item for the year ended December 31, 2004, as compared to such item for the year ended December 31, 2003.

Listing Fees. The following table sets forth the revenues from listing fees as reported and on a billed basis:

	Year ended December 31,
	Year ended December 31,								Percent Increase (Decrease)
	2004				2003				Percent Increase (Decrease)
	As Reported		Billed Basis		As Reported		Billed Basis		As Reported		Billed Basis

	$	329.8	$	320.9	$	320.7	$	294.6	2.8	%	8.9	%

For the year ended December 31, 2004, compared to the year ended December 31, 2003, listing fees increased $9.1 million, or 2.8%, on an as reported basis.

Listing fees are primarily derived from annual listing fees and original fees. Original fees are deferred and amortized over the estimated service period of 10 years. The difference between the as reported revenues and the billed basis revenues were due to the amortization of listing fees in accordance with U.S. generally accepted accounting principles.

Annual listing fees totaled $241.3 million for the year ended December 31, 2004 on both an as reported and billed basis, an increase of 3.9% over the year ended December 31, 2003. This increase was primarily due to additional listings during the year, for which annual fees were billed for the remaining portion of the year. Annual listing fees are recognized on a pro-rata basis over the calendar year.

290

Original fees totaled $88.5 million on an as reported basis. On a billed basis, original fees totaled $79.6 million for the year ended December 31, 2004, compared with $62.4 million for the year ended December 31, 2003, a 27.6% increase. Increases in original listings from 109 to 165 period over period, including higher merger and acquisition activity and increased stock splits, which drove higher revenues.

Market Information Fees. For the year ended December 31, 2004, compared to the year ended December 31, 2003, market information fees declined $4.8 million, or 2.8%. Market information fees for Tape A products declined due to a lower average number of monthly professional subscribers, resulting in a decrease of $6.2 million in professional device revenue. The remaining decline was attributed to Tape B, due to a decrease in the NYSE's share of the trades. The non-professional/usage segment was flat and there was a decrease in the access fees. These decreases were offset by a 35% increase in NYSE Proprietary Products revenue and an increase in NYSE's share of Tape A trades. NYSE OpenBook® subscriptions increased 20% year-on-year.

Trading Fees. For the year ended December 31, 2004, compared to the year ended December 31, 2003, trading fees fell $3.6 million, or 2.3%. Although average daily volume was up 4.6% in 2004, current pricing structures, including dollar caps and the 2% commission cap, inhibited the NYSE's ability to generate revenue growth despite higher trading activity.

Regulatory Fees. For the year ended December 31, 2004, regulatory fees were $113.3 million, with no significant change over that in the year ended December 31, 2003. Member regulation fees are driven by gross FOCUS revenue, which was flat year over year at $145 billion.

Facility and Equipment Fees. For the year ended December 31, 2004, compared to the year ended December 31, 2003, facility and equipment fees decreased $10.2 million, or 16.8%, to $50.4 million. The decrease resulted from the NYSE's decision to suspend the floor technology fee in July 2003, due to the prevailing poor economic environment for floor participants. This fee, instituted in 2003, was intended to recover the cost of providing services from those receiving value for the services.

Membership Fees. For the year ended December 31, 2004, compared to the year ended December 31, 2003, annual membership fees fell $2.7 million, or 24.5%, to $8.3 million. The drop was due to fewer electronic access membership renewals (29 in 2004 compared to 33 in 2003) and lower electronic access membership prices, reflecting lower lease prices on the floor. Transfer and other charges remained flat through the year.

Revenues—SIAC Services

Overview. The following table sets forth the revenues attributable to SIAC Services for the years ended December 31, 2004 and December 31, 2003, as well as the percentage increase or decrease for each consolidated statement of income item for the year ended December 31, 2004, as compared to such item for the year ended December 31, 2003.

Data processing fees—NYSE			266.1		253.0	5.2	%

	Total revenues	$	486.8	$	477.8	1.9	%

291

Data Processing Fees—Non-NYSE. For the year ended December 31, 2004, data processing fees were $220.7 million, $4.1 million, or 1.8%, lower than that in the year ended December 31, 2003. Lower revenues were driven by a decrease in data processing fees of major customers and lower revenues from Sector's communications services. These decreases were offset partially by increased decommissioning charges for a major customer, which is supplying itself services previously provided by SIAC, and communications revenues from the SFTI communications network.

Data Processing Fees—NYSE. For the year ended December 31, 2004, compared to that in the year ended December 31, 2003, data processing fees increased $13.1 million, or 5.2%, to $266.1 million, primarily due to increased requests for service from the NYSE related to additional initiatives for trading systems, billings to NYSE for its share of costs related to SIAC's workforce reduction, physical security enhancements and depreciation relating to a change in the estimated useful life of assets, resulting in generally shorter depreciation schedules and higher depreciation expenses.

Expenses—NYSE Market

Overview. The following table sets forth the expenses attributable to NYSE Market for the year ended December 31, 2004 and December 31, 2003, as well as the percentage increase or decrease for each consolidated statement of income item for the year ended December 31, 2004, as compared to such item for the year ended December 31, 2003.

	Total compensation	$	279.4	$	280.1	(0.3	)%

292

Compensation. For the year ended December 31, 2004, compared to 2003, compensation was down $0.7 million. Average headcount grew to 1,551 employees from 1,526, due principally to increased staffing in NYSE Regulation and other customer oriented areas. Reflecting competitive market forces, especially for regulatory personnel, the average salary across the NYSE increased 2.1% in 2004. These increases, as well as higher medical benefit and bonus expense, were offset by a change in the NYSE's Supplemental Executive Retirement Program, which reduced the cost of these benefits, and the nonrecurring nature of the one-time deferred compensation accrual for the former chairman and chief executive officer in 2003.

Systems and SIAC Support. For the year ended December 31, 2004, compared to 2003, systems costs increased $3.4 million or 9.9%. Maintenance contracts, vendor services and additional operating lease expenses contributed to the increase. SIAC support increased $10.8 million or 4.4%, due to an increase for funding of key initiatives related to trading floor technology, the NYSE's share of costs for SIAC's workforce reduction and physical security enhancements.

Professional Services. For the year ended December 31, 2004, compared to 2003, professional services expense rose $34.5 million, or 75.2%. This change was driven by higher legal and consulting expense, higher investment management fees and other related expenditures, including corporate governance and business development. Legal fees, net of insurance reimbursements in the current year, totaled $28.2 million in 2004 compared with $12.5 million in 2003. Legal fees in 2004, representing 35.1% of professional services for NYSE Market, were incurred principally in connection with the specialist investigation, litigation related to the former chairman and chief executive officer of the NYSE, and a patent infringement case. Consulting fees increased due to the numerous initiatives undertaken across the organization.

Depreciation and Amortization. For the year ended December 31, 2004, compared to 2003, depreciation and amortization expense rose $1.8 million, or 3.1%, as NYSE capital expenditures nearly doubled to $82.3 million from $43.3 million. The NYSE saw an increase in expenditures across all areas, including investments in infrastructure and trading floor technology. In addition, through 2004, the NYSE completed a review of its depreciation policies to better reflect useful life of the assets. This review resulted in additional expense of $1.7 million and will lead to higher anticipated depreciation expense in future years, reflecting generally shorter depreciation lives.

Occupancy. For the year ended December 31, 2004, compared to 2003, occupancy costs rose due to higher operating and electricity costs, a $0.3 million, or 0.8%, increase.

General and Administrative. For the year ended December 31, 2004, compared to 2003, general and administrative expense rose $3.6 million, or 5.5%, to $69.6 million. Non-advertising general and administrative expense was essentially flat, while advertising increased.

Regulatory Fine Income

For the year ended December 31, 2004, compared to the year ended December 31, 2003, regulatory fines collected decreased from $11.2 million to $7.6 million during the year. Regulatory fines result from disciplinary actions taken by NYSE Regulation in its oversight of its member organizations.

Expenses—SIAC Services

Overview. The following table sets forth the expenses attributable to SIAC Services for the years ended December 31, 2004 and December 31, 2003, as well as the percentage increase or decrease for each consolidated statement of income item for the year ended December 31, 2004, as compared to such item for the year ended December 31, 2003.

Benefits and Other			67.8		58.2	16.5	%

	Total compensation	$	248.5	$	245.1	1.4	%

Compensation. For the year ended December 31, 2004, compared to 2003, compensation increased $3.4 million, or 1.4%, to $248.5 million. Increased expenses were primarily due to decommissioning charges for a major customer, which in 2004, internalized the services previously provided by SIAC, as well as benefit expenses associated with workforce reduction. Average headcount (average of the month-end headcount during the period) dropped from 1,724 in 2003 to 1,599 in 2004, but did not impact the full year 2004 due to timing of the reductions.

Systems. For the year ended December 31, 2004, compared to 2003, systems costs decreased $10.8 million, or 9.7%, to $100.8 million, primarily due to Sector's cost containment initiatives and reductions of communications expenses.

Professional Services. For the year ended December 31, 2004, compared to 2003, professional services increased $2.4 million, or 4.4%, to $57.3 million. Average contract staff headcount increased slightly to 262 in 2004 from 251 in 2003 as new projects contributed to the need for additional services. Transition costs related to the decommissioning of services from a major customer also contributed to the increase.

Depreciation and Amortization. For the year ended December 31, 2004, compared to 2003, depreciation and amortization increased $4.9 million, or 16.0%, to $35.6 million. A review of depreciation policies in an effort to better reflect estimates of certain assets' lives occurred in 2004, which resulted in additional expense of $5.9 million in 2004 and will lead to higher anticipated depreciation expense in future years, reflecting generally shorter depreciation schedules. Capital expenditures in 2004 of $7.5 million also contributed to the increase.

Occupancy. For the year ended December 31, 2004, compared to 2003, occupancy costs increased $1.3 million, or 4.5%, to $30.3 million due primarily to rent for additional offsite space.

294

General and Administrative. For the year ended December 31, 2004, compared to 2003, general and administrative expense rose $4.2 million, or 40.0%, to $14.7 million, owing primarily to expenses related to the transition of services to a major customer, in 2004 internalized services previously provided to it by SIAC.

Investment and Other Income, net. For the year ended December 31, 2004, compared to the year ended December 31, 2003, investment and other income increased $7.1 million, or 32.1%. Declines in investment income were offset by reimbursements and recoveries from various sources throughout the year. Investment income fell 27% due to lower yields and greater volatility in the fixed income markets. Management undertook a complete review of the investment portfolio in 2004, including an analysis of risk, product diversification, all-in cost of management, and tax efficiency. Based on this review, the portfolio was reallocated in December 2004 to higher yielding and more tax-efficient securities. Offsetting the investment income declines were various settlement payments totaling $11.2 million that the NYSE received through the year. The key components were $3.2 million of insurance proceeds as a result of claims made for legal expenses incurred in prior years, and $6.4 million of recoveries related to business interruption and losses from the events of September 11, 2001.

Investment and Other Income, net. For the year ended December 31, 2004, compared to the year ended December 31, 2003, investment and other income decreased $5.1 million, or 49.5%, to $5.2 million, primarily as a result of net realized gains associated with SIAC's investment portfolio. During 2003, management undertook a complete review of the investment portfolio, asset allocations and fund manager performance. Based upon this review, the portfolio was rebalanced and reallocated. Sales of securities and improved stock market performance resulted in an increase in net realized gains during 2003.

Income Taxes

The overall effective tax rate for the years ended December 31, 2004 and December 31, 2003 was 28.0% and 42.3%, respectively. A decrease in net income before provision for income taxes of $60 million and the receipt of $6.4 million in 2004 of non-taxable insurance proceeds as a result of the September 11, 2001 events and receipt of $3.7 million in investment tax credits drove the year-over-year decrease in effective tax rate.

295

The following table sets forth the provision for income taxes, and the overall effective tax rate for the NYSE, on a consolidated basis, as well as for its two operating segments—NYSE Market and SIAC Services—for the years ended December 31, 2004 and December 31, 2003.

Liquidity and Capital Resources

Liquidity and Capital Resources as of June 30, 2006

Historically, NYSE Group's primary source of liquidity has been cash generated by the NYSE's operations, and NYSE Group's liquidity requirements have been for working capital, capital expenditures and general corporate use.

NYSE Group's working capital was $558.2 million at June 30, 2006, and capital expenditures equaled $39.8 million for the six months ended June 30, 2006. Capital expenditures related primarily to the development and maintenance of corporate and regulatory systems and to trading technology, including expenditures relating to the development and implementation of NYSE Hybrid Market and compliance with Regulation NMS.

Cash and cash equivalents are generated primarily from listing services, sales of market information, collection of activity assessment fees (which are fully remitted to the SEC), data processing services provided by SIAC, collections of regulatory fees (which are based on FOCUS filing amounts), fees generated for trading (which are generally based on volume and commissions subject to certain caps), and investment income.

At June 30, 2006, NYSE Group had $272.7 million of cash and cash equivalents, an increase of $229.2 million from its cash and cash equivalents at December 31, 2005. Current assets readily convertible into cash include accounts receivable, securities purchased under agreements to resell and marketable securities. These assets totaled $1,147.1 million at June 30, 2006 and, when combined with cash and cash equivalents, represented 91.1% of NYSE Group's current assets.

Under the terms of the operating agreement of the New York Stock Exchange, LLC, no regulatory fees, fines or penalties collected by NYSE Regulation may be distributed to NYSE Group or any entity other than NYSE Regulation. As a result, the use of regulatory fees, fines and penalties collected by NYSE Regulation may be considered restricted. As of June 30, 2006, NYSE Group did not have any significant restricted cash balance.

With respect to investment activities, the boards of directors of NYSE Group and SIAC have separately approved investment policies for externally managed portfolios. The goals of these policies are to preserve principal, maintain adequate liquidity at all times to fund budgeted operating and capital requirements, and to maximize returns relative to investing guidelines and market conditions. NYSE Group's current policies prevent it from investing directly in any equity type investment, however, this policy can be modified at the discretion of the chief executive officer and chief financial officer of NYSE Group, based on the delegation of authority by the board of directors. SIAC's policies permit investing in equity funds. Participants in supplemental executive savings and other deferred compensation plans are permitted to invest in equity funds. Under NYSE Group's policies, it may invest only in securities that are

296

rated AA or better by two nationally recognized rating organizations and that are in U.S. dollar denominations. A portion of SIAC's portfolio is used to fund its non-qualified benefit obligations. The average duration of the portfolios for both the NYSE Group and SIAC must not exceed two years. Both NYSE Group and SIAC periodically review their respective policies and investment managers.

As of June 30, 2006, NYSE Group had no outstanding short-term or long-term debt.

NYSE Group believes that cash flows from operating activities and financing capabilities along with future cash flows from operations are sufficient to meet the needs of its current operations. If existing cash balances are insufficient, NYSE Group intends to seek additional financing. NYSE Group may not be able to obtain additional financing on acceptable terms or at all.

Net cash provided by operating activities equaled $243.4 million for the six months ended June 30, 2006, consisting of net income of $91.5 million and the effects of non-cash items, such as depreciation, which does not adversely affect cash flows. Also, during the six months ended June 30, 2006, NYSE Group remitted $232.1 million to the SEC for Section 31 fees.

Net cash provided by investing activities equaled $479.9 million for the six months ended June 30, 2006. NYSE Group acquired $218.2 million of cash in connection with the Archipelago merger. Net sales in investment securities and securities purchased under agreements to resell of $275.7 million were liquidated to partially fund the $409.8 million distribution to NYSE former members.

As part of the merger, NYSE Group's financing activities included a total cash distribution of $506.2 million (consisting of a $409.8 million cash distribution and a $96.4 million dividend) to the NYSE's former members during the six months ended June 30, 2006.

Liquidity and Capital Resources as of December 31, 2005

Historically, the NYSE's primary source of liquidity has been cash generated by the NYSE's operations and its liquidity requirements have been for working capital, capital expenditures and general corporate purposes. The NYSE's working capital was $779.2 million at December 31, 2005. The NYSE's capital expenditures equaled $105.7 million for the year ended December 31, 2005. NYSE Market's capital expenditures (not including SIAC Services) equaled $84.2 million for the year ended December 31, 2005. NYSE Group's capital expenditures are expected to continue to relate primarily to the development and maintenance of NYSE's corporate and regulatory systems and to its trading technology, including expenditures relating to the development and implementation of NYSE Hybrid Market^SM and compliance with Regulation NMS.

Cash and cash equivalents are generated primarily from NYSE's listing services, sales of market information, collection of activity assessment fees (which are fully remitted to the SEC), data processing services provided by SIAC, collections of regulatory fees (which are based on FOCUS filing amounts), fees generated for trading (which are generally based on volume and commissions subject to certain caps), and investment income.

At December 31, 2005, the NYSE had $43.5 million of cash and cash equivalents, an increase of $28.0 million from its cash and cash equivalents at December 31, 2004. Current assets readily convertible into cash include accounts receivable, securities purchased under agreements to resell and marketable securities. These assets totaled $1,280.1 million at December 31, 2005 and, when combined with cash and cash equivalents, represented 90.4% of NYSE's current assets.

With respect to investment activities, the boards of directors of the NYSE and SIAC have separately approved investment policies for externally managed portfolios. The goals of these policies are to preserve principal, maintain adequate liquidity at all times to fund budgeted operating and capital requirements, and to maximize returns relative to investing guidelines and market conditions. The NYSE's current policies prevent it from investing directly in any equity type investment; however, this policy can be

297

modified at the discretion of the chief executive officer and chief financial officer of NYSE Group, based on a delegation of authority by the NYSE Group board of directors. SIAC's policies permit investing in equity funds. Participants in supplemental executive savings and other deferred compensation plans are permitted to invest in equity funds. Under the NYSE's policies, it may invest only in securities that are rated AA or better by two nationally recognized rating organizations and that are in U.S. dollar denominations. A portion of SIAC's portfolio is used to fund its non-qualified benefit obligations. The average duration of the portfolios for both the NYSE and SIAC must not exceed two years. Both the NYSE and SIAC periodically review their respective policies and investment managers.

NYSE Group's future cash flows could fluctuate as a result of a number of factors, including: (1) changes in the demand for the NYSE's services resulting from changes in the number of initial public offerings (which generate original and annual listing fees) or the number of NYSE-listed companies that delist from the NYSE (which has an impact on annual listing fees collected by the NYSE); (2) changes in the NYSE's share of Tape A trades (which has an impact on the amount of market information revenues that the NYSE collects); (3) changes in the demand for data processing services from SIAC customers; (4) changes in volume or commissions on which trading fees are generated; (5) changes in FOCUS revenues reported by NYSE members (on which regulatory fees are calculated); and (6) changes in the fixed income environment in which the NYSE's investment portfolio is primarily invested. The NYSE implemented certain changes to its pricing for floor facility fees, which were filed with the SEC for immediate effectiveness on December 29, 2005 and became operative as of January 1, 2006. NYSE Group cannot predict the impact that such fee changes will have on liquidity, as a portion of these pricing changes are based on volumes traded in NYSE-listed securities, which cannot be projected. The NYSE has also introduced trading licenses, of which 1,274 were sold at an annualized price of $49,290.

Under the terms of the operating agreement of New York Stock Exchange, LLC, no regulatory fees, fines or penalties collected by NYSE Regulation may be distributed to NYSE Group or any entity other than NYSE Regulation. As a result, the use of regulatory fees, fines and penalties collected by NYSE Regulation may be considered restricted, and NYSE Group may be required to report the related cash balances, if any, as restricted cash in future periods.

As of December 31, 2005, the NYSE had $43.5 million of cash, had no outstanding short-term or long-term debt, and had no lines of credit. NYSE Group believes that cash flows from operating activities are sufficient for it to fund its current operations for at least the next 12 months, such as legal and other related items. If existing cash balances are insufficient, NYSE Group intends to seek additional financing. NYSE Group may not be able to obtain additional financing on acceptable terms or at all.

Operating Activities

Operating cash flows equaled $264.5 million for the year ended December 31, 2005, consisting of net income of $40.7 million and the effects of non-cash expenses and changes in working capital. The NYSE remits payments to the SEC biannually and, as of December 31, 2005, $232.1 million was payable to the SEC. Amounts are collected from NYSE members under Rule 440h in order to cover the SEC Section 31 fees.

Investing Activities

Net cash used in investing activities equaled $222.2 million for the year ended December 31, 2005. This cash was used to make additional investments in marketable securities and capital expenditures in upgrading the NYSE's trading floor technology and corporate and regulatory systems.

Quantitative and Qualitative Disclosure About Market Risk

Market risk represents the risks of changes in the fair value of financial instrument, derivative or non-derivative, caused by fluctuation in interest rates and equity prices. The primary market risk is associated

298

with fluctuations in interest rates and the effects that such fluctuations may have on an investment portfolio. As of December 31, 2005, investments consist of fixed income instruments with an average duration of 0.57 years for NYSE Market. SIAC's investments at December 31, 2005 consisted of mutual funds. Both portfolios' investment objective is to invest in securities to preserve principal while maximizing yields, without significantly increasing risk. These investment securities are subject to interest rate risk and their fair values may fluctuate with changes in interest rates. Management does not believe that a 100 basis point fluctuation in market interest rates will have a material effect on income or cash flows from, or the carrying value of, the investment portfolios as of December 31, 2005.

NYSE Group does not believe that it has material exposure to interest rate or foreign currency risks as of December 31, 2005. Furthermore, NYSE Group has not entered into any derivative contracts to mitigate such risks.

Summary Disclosures About Contractual Obligations and Off-Balance Sheet Arrangements

Contractual Obligations

The NYSE also has obligations related to the deferred compensation and other post-retirement benefits. The date of payment under these obligations cannot be determined.

Off-Balance Sheet Arrangements

In January 2006, the NYSE entered into a standby letter of credit of $265,000. The standby letter of credit is intended to be utilized by an insurance vendor as part of the vendor's collateral requirements. NYSE Group will fund any additional collateral requirements from operating cash flows and, as such, does not intend to use this standby letter of credit.

Critical Accounting Policies and Estimates

The following provides information about NYSE Group's critical accounting estimates. Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions.

Revenue Recognition

Listing fees include original fees, which are paid whenever a company initially lists on the NYSE and whenever it effects a corporate action that results in the listing of additional shares. Companies also pay annual fees to remain listed on the NYSE. Annual fees are recognized ratably over the course of the related period. Original fees are recognized on a straight-line basis over their estimated service period.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is maintained at a level that management believes to be sufficient to absorb probable losses in the NYSE's accounts receivable portfolio and is assessed periodically by

299

management. Increases in the allowance for doubtful accounts are charged against operating results and the allowance is decreased by the amount of write-offs, net of recoveries. The allowance is based on several factors, including a continuous assessment of the collectibility of each account. In circumstances where a specific customer's inability to meet its financial obligations is known, the NYSE records a specific provision for bad debts against amounts due to reduce the receivable to the amount it reasonably believes will be collected. Accounts with outstanding balances in excess of 60 to 90 days are reviewed monthly to make changes to the allowance as appropriate.

Income Taxes

The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax assets and liabilities for the future tax consequences of events that have been recognized in an entity's financial statements or tax returns. NYSE Group reviews its deferred tax assets for recovery; when it believes that it is more likely than not that a portion of its deferred tax assets will not be realized, a valuation allowance is established. Significant judgment is required in assessing the future tax consequences of events that have been recognized in its financial statements or tax returns. Fluctuations in the actual outcome of these future tax consequences could have a material impact on its financial position or results of operations.

Pension and Other Post-Retirement Employee Benefits (OPEB)

Pension and OPEB costs and liabilities are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on plan assets, mortality rates, and other factors. In accordance with U.S. generally accepted accounting principles, actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense and the recorded obligation in future periods. While NYSE Group management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect NYSE Group's pension and other post-retirement obligations and future expense.

Software Development

NYSE Group accounts for software development costs under AICPA Statement of Position 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use," and other related guidance. NYSE Group expenses software development costs as incurred during the preliminary project stage, while it capitalizes costs incurred during the application development stage, which included design, coding, installation and testing activities. Amortization of capitalized software development costs is computed on a straight-line basis over the software's estimated useful life, generally three years.

New Accounting Pronouncements

In July 2006, the Financial Accounting Standard Board (FASB) issued FASB Interpretation No. (FIN) 48, Accounting for Uncertainty in Income Taxes, an interpretation of Statement of Financial Standards (SFAS) No. 109, Accounting for Income Taxes. FIN 48 addresses how a reporting company accounts for all tax positions including the uncertain tax positions reflected or expected to be reflected in the company's past or future tax returns. The interpretation also requires the company to recognize interest and penalties associated with the uncertain tax positions. This interpretation is effective for fiscal years beginning after December 15, 2006. NYSE Group is currently evaluating the potential impact, if any, that the implementation of FIN 48 will have on its financial condition, results of operations and cash flows.

300

years ending after December 15, 2006. This decision requires the recognition on the statement of financial condition of the funded status of pension and other postretirement benefit plans. NYSE Group is currently evaluating the potential impact, if any, that the implementation will have on its stockholders' equity.

Controls and Procedures

As of June 30, 2006, NYSE Group evaluated, under the supervision and with the participation of its management, including its chief executive officer and chief financial officer, the effectiveness of the design and operation of the disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act, of NYSE Group and its subsidiaries. Based upon that evaluation, NYSE Group's chief executive officer and chief financial officer concluded that the design and operation of the disclosure controls and procedures were effective as of June 30, 2005. No significant changes were made in NYSE Group's internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting during the six months ended June 30, 2006. In July 2006, NYSE Group substantially completed a company-wide implementation of a single general ledger system. As of August 1, 2006, all of NYSE Group's subsidiaries were using this system. NYSE Group has reviewed the internal controls affected by this implementation and believes that the internal controls surrounding the general ledger system, as modified, are appropriate and functioning effectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF ARCHIPELAGO

Business Development

Archipelago's business grew substantially since it began trading operations in January 1997 on the Archipelago ECN, the precursor to ArcaEx (which, together with the Pacific Exchange, is now known as NYSE Arca). Archipelago attributes the growth of its business to the change in its business model and its organic and external growth. These developments included:

•: Archipelago's Alliance with (and Subsequent Acquisition of) the Pacific Exchange.Beginning in March 2002, Archipelago began the migration of trading activities in exchange-listed securities to ArcaEx, which it extended to Nasdaq-listed securities on a phased basis in February 2003. During this transition period, Archipelago continued to operate the Archipelago ECN until Archipelago completed the migration of all Nasdaq-listed securities to ArcaEx in April 2003. This document refers to the Archipelago ECN and ArcaEx, collectively, as the Archipelago system. As the operator of the exclusive equities trading facility of PCX Equities, Archipelago became eligible to earn revenues from two additional sources, market data fees and listing fees, and Archipelago also reduced its clearing costs. On September 26, 2005, Archipelago completed its acquisition of PCX Holdings and its subsidiaries. As a result of its acquisition of PCX Holdings, Archipelago operates an exchange for trading equity options listed on exchanges, including the facilities, technology, systems and regulatory surveillance and compliance services required for the operation of a marketplace for trading options. The results of PCX Holdings for 2005 were as follows: for the nine months ended September 30, 2005, PCX Holdings had an operating loss of $2.5 million; for the three months ended December 31, 2005, PCX Holdings had operating income of $4.5 million. As a result of the completed acquisition of PCX Holdings on September 26, 2005, the results of PCX Holdings for the three month period ended December 31, 2005 were consolidated into Archipelago's financial statements.
•: Strategic Transactions. In 2002, Archipelago completed two strategic transactions: Archipelago's merger with REDIBook ECN LLC, and Archipelago's acquisition of GlobeNet Securities, Inc. REDIBook was a competing ECN that had a trading share similar to Archipelago's ECN at the time of the acquisition. The REDIBook acquisition allowed Archipelago to significantly increase Archipelago's trading volume in Nasdaq-listed securities. In the GlobeNet acquisition, Archipelago acquired intangible technology assets; including a matching engine technology platform that GlobeNet had used to develop an alternative trading system for bulletin board stocks. This acquisition increased Archipelago's technology resources, which led to the development of software applications for Archipelago's trading platform.
•: Growth in Trading Volumes and Increased Internal Match Rate. Through internal growth and the REDIBook merger, Archipelago was able to increase its share volumes in U.S. equity securities traded on the Archipelago system. See "Management's Discussion and Analysis of Financial Condition and Results of Operations of Archipelago—Key Statistical Information." Archipelago's transaction fees accounted for 93.5% of its total revenues in 2003, 89.5% of its total revenues in 2004 and 86.1% of its total revenues in 2005.

As discussed above, in recent years, Archipelago has experienced significant growth in its trading volumes, which exceeded its growth in revenues. This trend resulted from declining revenue per transaction, which NYSE Group believes has been driven by increased price competition and the resulting shift in the market fee structure. In addition to growth in trading volumes, Archipelago witnessed an increasing percentage of share volume (as well as of shares handled on ArcaEx) executed within its internal liquidity pool or "matched internally." It is believed that this trend has been driven by: (i) industry consolidation, its acquisitions and a more competitive market environment; (ii) the migration of its trading operations to a more reliable trading platform in connection with the launch of ArcaEx, which NYSE

302

Group believes has attracted more customers to its system and (iii) its sales and marketing efforts and its customers' pursuit of greater cost efficiencies, which led them to rely on Archipelago's technology and embed it in their infrastructure, enabling them to do business with Archipelago more easily.

Business Environment

Like the NYSE, Archipelago operated in a business environment characterized in recent years by challenging business and economic conditions, intense competition among market participants and an increased focus on electronic trading due to technological advancements and regulatory changes. Archipelago's business was impacted by the following key factors:

•: trading volumes in U.S. equity securities and options, which are driven by overall macroeconomic conditions;
•: competition (in terms of trading share, pricing and product and service offerings);
•: technological advancements; and
•: regulatory developments.

The interplay of these factors affected Archipelago's revenues and profitability. For a discussion of these factors and their impact on Archipelago's historical results, see "Management's Discussion and Analysis of Financial Condition and Results of Operations of NYSE Group—Sources of Revenues," "Management's Discussion and Analysis of Financial Condition and Results of Operations of NYSE Group—Components of Expenses" and "Management's Discussion and Analysis of Financial Condition and Results of Operations of NYSE Group—Results of Operations." See also "Risk Factors—Risks Relating to NYSE Euronext's Business—Market fluctuations and other risks beyond NYSE Euronext's control could significantly reduce demand for its services and harm its business."

Archipelago Reorganization

On August 11, 2004, Archipelago converted from a Delaware limited liability company (Archipelago Holdings, L.L.C.) to a Delaware corporation (Archipelago Holdings, Inc.). Archipelago's conversion to the corporate form of organization did not have any material effect on its consolidated financial statements. When the term "Archipelago" is used in the following discussion, it means, prior to the conversion, Archipelago Holdings, L.L.C., a Delaware limited liability company, and its consolidated subsidiaries and, after the conversion, Archipelago Holdings, Inc., a Delaware corporation, and its consolidated subsidiaries.

Income Taxes

As a limited liability company, Archipelago was treated as a partnership for federal, state and local income tax purposes. As a result, all items of income, expense, gain and loss of Archipelago were generally reportable on the tax returns of members of Archipelago Holdings, L.L.C. Accordingly, Archipelago made no provisions for income taxes at the company level.

Following Archipelago's conversion to a corporation, its earnings were subject to federal, state and local income taxes at a combined rate of approximately 42.5% and 41.5% for the years ended December 31, 2005 and 2004, respectively. For the year ended December 31, 2004, Archipelago's effective tax rate was 9.2% primarily because the taxable income Archipelago generated from January 1, 2004 through August 11, 2004—the date Archipelago converted to the corporate form of organization—was the responsibility of Archipelago Holdings, L.L.C.'s members. Archipelago does not have any deferred tax assets related to Archipelago Holdings, L.L.C.'s net operating loss carry forwards, as those losses were incurred when it was treated as a partnership for federal income tax purposes.

303

Segment Reporting

For financial reporting purposes, Archipelago's business was divided into two reportable segments: Transaction Execution Services and Agency Brokerage Services. Archipelago's Transaction Execution Services business included trade execution on the Archipelago system as well as fees that Archipelago received for market data and from issuers with equity securities listed on the Pacific Exchange for trading on ArcaEx. Archipelago's trade execution customers were required to hold an ETP or be a broker-dealer introduced to ArcaEx by an ETP holder in order to trade on ArcaEx. An ETP holder must be a broker-dealer. Archipelago's Agency Brokerage Services were provided through Wave Securities, Archipelago's broker-dealer subsidiary, and consisted of order execution services, on an agency basis, for orders received exclusively from institutions involving primarily exchange-listed securities.

Because Archipelago's Agency Brokerage Services were discontinued, the information required to be disclosed by SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, is no longer required.

Following the September 2005 acquisition of PCX Holdings, Archipelago's business was divided into two reportable segments: ArcaEx Equities and ArcaEx Options. The ArcaEx Equities business included the reportable segment formerly named Transaction Execution Services. The ArcaEx Options business consisted primarily of transaction execution services, market data services on a real-time or summary basis and a trading venue for issuers of options contracts. The customers of ArcaEx Options were required to hold an Option Trading Permit, or OTP.

Sources of Revenues

In its transaction execution business, Archipelago derived revenues from three sources: transaction fees, market data fees and listing and other fees.

Transaction Fees. Archipelago's revenues in its transaction execution services segment were derived primarily from transaction fees, which Archipelago charged customers for trade execution of equity securities on the Archipelago system and equity options on the Pacific Exchange. Archipelago earned transaction fees for: (i) customer orders of equity securities matched internally on ArcaEx, as well as for customer orders routed out and (ii) customer orders of equity options traded or cleared through the Pacific Exchange.

For equity securities, Archipelago charged a per share fee (denominated in tenths of a cent per share) to each customer that executed against a buy order or sell order posted internally on the Archipelago system. Archipelago referred to these customers when they purchase or sell securities as "liquidity takers," as they removed liquidity from the Archipelago system. A liquidity taker may be either a purchaser or a seller, and is distinguished from a "liquidity provider" generally by the type of buy order or sell order it posts on Archipelago's system. A liquidity provider will likely enter a non-marketable limit order on the Archipelago system (i.e., either a limit order to buy a security with a limit price below the best offer or a limit order to sell a security with a limit price above the best bid). Non-marketable limit orders were placed on the Archipelago limit order book and await execution. A liquidity taker, on the other hand, is likely to enter a marketable limit order (i.e., a limit order to buy a security with a limit price at or above the best offer or a limit order to sell a security with a limit price at or below the best bid for that security). Accordingly, liquidity providers generally "post" buy orders or sell orders that are subsequently executed against by the sell order or buy order, as the case may be, of a customer that is the liquidity taker. As discussed below, Archipelago paid liquidity providers a per share fee for posting buy orders and sell orders on Archipelago's system.

Archipelago also charged a per share fee (denominated in tenths of a cent per share) to customers whose orders of equity securities were routed out to an external market center displaying the best buy order or sell order in the market for a particular security.

304

The amount of transaction fees Archipelago earned for trading of equity securities in any period fluctuated based upon: (i) trading volumes of shares handled and (ii) the prices Archipelago charged for trade execution. As a result of increased price competition, in the past, Archipelago reduced the amount per share it charged customers for taking liquidity from the Archipelago system, as well as for routing orders to an external market center.

Market Data Fees. Following the launch of ArcaEx in March 2002, Archipelago began earning revenues from market data fees in connection with the sale of its market data pursuant to the Consolidated Tape Association Plan, or CTA Plan, in the case of exchange-listed securities, and the Nasdaq OTC/UTP Plan, in the case of Nasdaq-listed securities. As an ECN, Archipelago was ineligible to participate in these Plans directly. Under the Plans, the information collected from all participants was sold to data vendors that in turn sold the data to third-party consumers such as Thomson Financial Inc. and Bloomberg, L.P. Under the CTA Plan, Archipelago's market data fees were directly related to both the percentage of its trades in exchange-listed securities executed on ArcaEx that were reported through the CTA Plan and the size of the revenue sharing pool. Under the Nasdaq OTC/UTP Plan, Archipelago shared revenues with Nasdaq and exchanges that are members of the Nasdaq OTC/UTP Plan and that trade Nasdaq-listed securities. The market data fees Archipelago received under this plan were directly related to the total shares and trades that are executed on ArcaEx as a percentage of all shares and trades executed in Nasdaq-listed securities. Archipelago did not earn market data fees in connection with customer orders or shares handled that were routed out to an external market center for execution.

In 2005, Archipelago rebated 50% of the market data fees it received under the CTA Plan to customers that traded exchange-listed securities (except with respect to NYSE-listed securities), including exchange-traded funds, on ArcaEx based on their aggregate exchange-listed trading activity. Archipelago introduced this revenue rebate plan in the fourth quarter of 2002, and set the rate at 50% in response to competitive market conditions. In the future NYSE Arca may, at its discretion, change the percentage of fees it rebates or eliminate the plan. For financial reporting purposes, Archipelago recorded its market data fees net of amounts rebated to customers under this revenue rebate arrangement. Archipelago rebated approximately 27.6% of the total market data fees it received in both 2005 and 2004. Archipelago initiated its revenue rebate plan to encourage customers to execute trades of exchange-listed securities on ArcaEx and to remain competitive with other market centers. The SEC does not permit market data fees generated under the Nasdaq OTC/UTP Plan to be rebated to participants in this manner.

Listing Fees. Under Archipelago's facility services agreement with the Pacific Exchange, Archipelago was entitled as the operator of ArcaEx to all listing fees from issuers that list their equity securities on the Pacific Exchange. After launching ArcaEx in March 2002, Archipelago began receiving listing fees from legacy issuers that had selected the Pacific Exchange as a listing venue and maintained their listing following the creation of ArcaEx, as well as from new listings on the Pacific Exchange. Since the launch of ArcaEx in March 2002, there have been only 6 new listings of equity securities on the Pacific Exchange. Listing fees represented less than 1.0% of Archipelago's total revenues in 2005.

Activity Assessment Fees. In 2005, Archipelago paid SEC fees pursuant to Section 31 of the Exchange Act. These fees were designed to recover costs incurred by the government for the supervision and regulation of securities markets and securities professionals. Archipelago, in turn, collected activity assessment fees from ETP and OTP holders trading on ArcaEx and the Pacific Exchange, respectively, and paid Section 31 fees to the SEC based on fee schedules determined by the SEC. Fees received were included in cash and cash equivalents at the time of receipt, and, as required by law, the amount due to the SEC is recorded as an accrued liability and remitted semiannually. Following the September 2005 acquisition of PCX Holdings, activity assessment fee revenue and Section 31 fee expense were presented gross on Archipelago's consolidated statement of operations. Activity assessment fee revenue and Section 31 fee expense had no impact on Archipelago's consolidated statement of operations.

305

Quarterly Fluctuations

In the securities industry, quarterly revenue fluctuations are common and are due primarily to variations in trading volumes, competition and technological and regulatory changes. Typically, revenues are lowest in the third quarter, primarily in August, due to reduced trading activity during the summer months.

Related Party Revenues

Some of Archipelago's customers were also its investors. Revenues generated from Archipelago's investors represented 38.0%, 43.3% and 42.8% of its total revenues, respectively, in 2005, 2004 and 2003. Archipelago generated 9.6%, 10.2% and 14.2% of its total revenues, respectively, in 2005, 2004 and 2003 from The Goldman Sachs Group, Inc. and its subsidiaries. For more information regarding Archipelago's transactions with its investors as its customers, see Archipelago's Consolidated Financial Statement and Note 13 thereto included elsewhere in this prospectus.

Components of Expenses

Archipelago's business was dependent on the liquidity of the Archipelago system (i.e., the number and range of buy orders and sell orders posted on its system and available to its customers). As a result, Archipelago's most significant cost of generating revenues was the cost of liquidity, which Archipelago paid for in one of two ways. First, to enhance the liquidity of its system, Archipelago paid a small fee per share (denominated in tenths of a cent per share) to participants, referred to as "liquidity providers," that posted buy orders and sell orders on the Archipelago system, when the quote was executed against, or "hit," by liquidity takers purchasing or selling securities internally on Archipelago's system. Archipelago began incurring the cost of liquidity payments in April 2002. Archipelago did not pay these fees for orders posted in NYSE-listed securities. Second, as part of its best execution business model, Archipelago incurred routing charges when the Archipelago system did not have the best buy or sell order in the market for a security that a customer was trying to buy or sell on Archipelago's system. In that case, Archipelago routed the customer's order to the external market center that displayed the best buy order or sell order. The external market center charged Archipelago a fee per share (denominated in tenths of a cent per share) for routing to its system.

As a general matter, the pricing model for transaction execution services has changed over time in response to increasing competition. As the amount of liquidity is determined by the number and ranges of buy or sell orders posted to a particular trading platform, the concept of paying liquidity providers developed to encourage these customers to place their orders on the trading system that paid them a per share fee to post their order. As discussed above, Archipelago began paying fees to liquidity providers in April 2002. Making liquidity payments and incurring routing charges are part of the costs Archipelago incurs to generate revenues through increased liquidity on the Archipelago system. Archipelago sought to reduce these costs by increased trade execution on the Archipelago system. Archipelago's cost of liquidity generally fluctuated based on (i) trading volumes and (ii) the per share fee Archipelago paid liquidity providers for trades executed internally on ArcaEx or the per share routing charge Archipelago paid to external market centers for outbound trades. Under Regulation NMS, liquidity payments and routing charges could be functionally eliminated due to the cap that would be imposed on access fees, which could impact the liquidity of NYSE Arca's platform.

In addition to liquidity payments and routing charges, Archipelago also incurred clearance, brokerage and related transaction expenses, which included transaction expenses paid to clearing entities for clearing and settlement, service fees paid per trade to exchanges for trade execution, costs incurred due to erroneous trade execution and charges Archipelago recorded from time to time for doubtful accounts, or bad debt, once Archipelago determined a receivable was not likely to be collected. Prior to the completion of the PCX Holdings acquisition, the contractual right to operate ArcaEx as the exclusive equities trading

306

facility of the Pacific Exchange and PCX Equities (and following the completion of the PCX Holdings acquisition, Archipelago's ownership of the Pacific Exchange and PCX Equities), allowed Archipelago not to incur clearing charges for trades executed on ArcaEx by two independent market participants. As a result, Archipelago's cost per trade was lower for trades executed internally on ArcaEx. If Archipelago routed a trade to an external market center, it bears clearing and settlement costs.

In addition, Archipelago incurred the following expenses:

•: NYSE merger costs and related executive compensation;
•: employee compensation and benefits expenses, which included salaries, incentive compensation (including stock-based compensation) and related employee benefits and taxes;
•: depreciation and amortization expenses, which resulted primarily from the depreciation of the fixed assets Archipelago purchases, including computer software and hardware used in the development of Archipelago's trading systems;
•: communications expenses, which consisted primarily of costs for Archipelago's network connection with its customers and its data centers, as well as connectivity to various other market centers;
•: marketing and promotion expenses, which consisted primarily of media, print and other advertising expenses as well as customer marketing expenses;
•: legal and professional expenses, which consisted primarily of legal and accounting expenses;
•: occupancy expenses, which consisted primarily of rental expenses; and
•: general and administrative expenses, which included insurance, travel and entertainment expenses and other administrative expenses and general office costs.

As a public company, Archipelago was subject to the provisions of the Sarbanes-Oxley Act of 2002, which required it to incur significant expenditures to establish systems, and to hire and train personnel to comply with these requirements.

In addition, starting in the first quarter of 2006, Archipelago is required to recognize in its financial statements the compensation costs associated with share-based payment transactions, including stock options. For the year ending December 31, 2006, management anticipates that Archipelago will recognize a pre-tax expense of approximately $2.0 million in connection with share-based payment transactions.

Key Statistical Information

Archipelago's revenues and certain of Archipelago's expenses were directly impacted by trading volumes of U.S. equity securities on the Archipelago system. Archipelago's profitability depended to a significant extent on its ability to attract and retain trading volumes, both in absolute terms and relative to other market centers. Archipelago derived revenues on both a per-share basis and a per-transaction basis, depending upon the source of revenue. The transaction fees Archipelago received for trade execution, and the payments Archipelago made to liquidity providers, were determined on a per share basis. Market data fees for exchange-listed securities were determined on a per transaction basis, and market data fees for Nasdaq-listed securities were determined based on a combination of share volume and transaction volume.

(1): U.S. market volume is calculated based on the trading of shares of equity securities listed on the NYSE, Nasdaq, AMEX, and other regional exchanges, including exchange-traded funds, as reported in the consolidated tape. The "consolidated tape" is the system that continuously provides the last sale price and volume of securities transactions in listed securities to the public.
(2): Archipelago's trading share is calculated based on the number of shares handled on the Archipelago system as a percentage of total volume.
(3): Represents Archipelago's share of the total volume of such securities handled on ArcaEx that was either matched internally on ArcaEx or routed out to an external market center.
(4): The per share amount is calculated based on Archipelago's total revenues derived from equity transaction fees of $425.0 million, $434.5 million and $380.6 million for the years ended December 31, 2005, 2004 and 2003, respectively.

308

(5): The per share amount is calculated based on Archipelago's cost of revenues derived from transaction fees, which consist of routing charges and liquidity payments of $273.6 million, $292.2 million and $268.1 million for the years ended December 31, 2005, 2004 and 2003, respectively. The cost of revenue from transaction fees used in the per share computation does not include clearance, brokerage, other transaction expenses and certain other indirect expenses.
(6): The per share amount is calculated based on Archipelago's net revenues received from transaction fees, and Archipelago's total U.S. market volume for the relevant period.
(7): The percentage of customer order volume matched internally is calculated by dividing the volume of customer orders executed within Archipelago's internal liquidity pool (including the volume of both buy orders and sell orders) by the total volume of customer orders (again including the volume of both buy orders and sell orders when such orders are matched internally). The percentage of customer orders routed out is calculated by dividing the volume of customer orders routed to other market centers by the total volume of customer orders.

For purposes of calculating its volume, Archipelago included all shares that are "handled" on the Archipelago system. Handled shares include both shares that were bought or sold within Archipelago's internal liquidity pool and shares that were routed to external markets for execution. Archipelago counted every transaction handled by the Archipelago system once; Archipelago did not count both sides of any transaction. For example, if a customer's 10,000 share buy order was matched with another customer's 10,000 share sell order in Archipelago's internal liquidity pool, Archipelago's handled volume would be 10,000 shares. As another example, if one of Archipelago's customers sent it an order to buy 10,000 shares and the best price for that order is displayed at another market center, Archipelago would have routed that order to the other market center for execution. The other market center would report a 10,000 share transaction in the consolidated tape, and Archipelago's handled volume would have been 10,000 shares. As a result, the 10,000 shares Archipelago reported as handled by it in this example were also handled by the external market center.

In computing the percentage of customer order volume matched internally and the percentage of customer order volume routed out, Archipelago calculated the percentage based on the volume of individual customer orders, not the volume of matched trades (i.e., only counting one side of a matched transaction). For example, Archipelago calculated two customer orders matched internally on its system as two customer orders matched internally, and it included the volume of both the buy order and the sell order in computing its percentages of customer order volume matched internally and routed out. Archipelago calculated one customer order routed to an external market center (which was matched with an order at that other market center) as one outbound trade or one customer order. Archipelago calculated one customer order routed to it from an external market center and matched with an order on its system as one inbound trade or one customer order.

Transactions in Nasdaq and exchange-listed securities are reported in the consolidated tape, a high-speed system that continuously provides last sale price and volume in listed securities. Archipelago's handled volume was higher than its volume reported to the centralized aggregators for inclusion in the consolidated tape for two reasons. First, Archipelago did not report trades routed to another market center to the centralized aggregators of this data. Instead, the destination market center reported these trades. For example, if a customer's 10,000 share buy order was routed to another market center for execution, Archipelago's handled volume would have been 10,000 shares, but it would not have reported the trade. Second, its handled volume included odd lot transactions, generally defined as trades of fewer than 100 shares, which, by rule, Archipelago did not report to the centralized aggregators for inclusion in the consolidated tape. For example, if one of Archipelago's customers bought 50 shares, its handled volume would have been 50 shares but it would not have reported this trade.

For purposes of calculating its trading share, Archipelago used the volume of shares that were handled on the Archipelago system (as described above) as the numerator, and the aggregate volume of

309

shares reported by all securities exchanges and associations in the consolidated tape as the denominator. Archipelago's trading share could have been expressed as:

Number of shares handled on the Archipelago system
Overall market volume as reported in the consolidated tape

As an alternative method of calculating trading share, Archipelago could have included in the numerator of the above formula only transactions that it reported in the consolidated tape. This would have excluded shares routed to other market centers and odd-lot transactions from its trading share calculation.

For purposes of calculating the percentage of handled shares matched internally or routed out, Archipelago counted all shares that were "handled" on the Archipelago system as described above. Archipelago counted every transaction handled by the Archipelago system once; Archipelago did not count both sides of any transaction. Therefore, if five trades were executed on ArcaEx for 10,000 shares each, three of which are routed out, Archipelago would have handled 50,000 shares and its percentage of that share volume matched internally would have been 40% and routed out would have been 60%.

Alternatively, for the purpose of calculating the percentage of customer order volume matched internally or routed out, Archipelago counted each customer order exactly once. If two customers' orders were matched within its internal liquidity pool, Archipelago counted the volume of both the buy order and the matched sell order. On the other hand, if a customer's order was routed to another market center and matched with an order posted at that other market center, Archipelago counted only the volume of the order routed out.

Highlights

For the year ended December 31, 2005, Archipelago's income from continuing operations decreased to $12.5 million, a $44.9 million decline compared to $57.4 million for the year ended December 31, 2004. Archipelago's operations for the period primarily reflect the following principal factors:

•: Increased volume and lower trading share. While Archipelago's total volume traded increased 2.9% to 144.3 billion shares for the year ended December 31, 2005 from 140.3 billion shares for the year ended December 31, 2004, its trading share of the total U.S. equity trading volume (Nasdaq-, NYSE- and AMEX-listed securities) declined to 13.8% for 2005 from 14.2% for 2004.

312

•: More liquidity posted on ArcaEx. The percentage of customer orders matched internally increased to 88.8% in 2005 from 86.6% in 2004 and therefore reduced the percentage routed to other market centers, resulting in a change in the amount and mix of the following expenses:
•: liquidity payments increased to $206.9 million, or 41.9% of total revenues in 2005, from $203.5 million, or 41.4% of total revenues in 2004;
•: routing charges declined to $66.7 million, or 13.5% of total revenues in 2005, from $88.7 million, or 18.1% of total revenues in 2004; and
•: clearance, brokerage and other transaction expenses declined to $5.9 million, or 1.2% of total revenues in 2005, from $13.7 million, or 2.8% of total revenues in 2004.
•: Increased expenses. Despite the positive impact of the additional liquidity posted on ArcaEx, Archipelago's operating income declined $43.7 million, or 71.5%, to $17.4 million for the year ended December 31, 2005 from $61.1 million for the year ended December 31, 2004. This was primarily associated with $46.1 million of expenses incurred in 2005 in connection with Archipelago's merger with NYSE, including legal, banking and regulatory fees, and the acceleration of certain executive compensation associated with the merger. Archipelago did not incur such costs in 2004.

Total U.S. share volume in equity securities (Nasdaq-, NYSE-, and AMEX-listed shares) increased by 5.8% to 1,047.7 billion shares for the year ended December 31, 2005 from 990.5 billion shares for the year ended December 31, 2004. Over the same period, Archipelago's total U.S. market volume increased 2.9% from 140.3 billion shares to 144.3 billion shares. For the year ended December 31, 2005, Archipelago handled 23.0%, 3.6% and 30.0% of the consolidated trading volume in Nasdaq-, NYSE-, and AMEX-listed equities, respectively. This compares to 25.2%, 1.8% and 22.7% for the year ended December 31, 2004.

Revenues

Archipelago's total revenues (excluding activity assessment fees) increased by $2.1 million, or 0.4%, from $491.3 million for the year ended December 31, 2004 to $493.4 million for the year ended December 31, 2005.

Transaction fees declined to $425.0 million for the year ended December 31, 2005 from $434.5 million for the year ended December 31, 2004, a decrease of $9.5 million, or 2.2%. Transaction fees in 2004 were made up entirely of revenues generated by Archipelago's ArcaEx Equities segment. For the year ended December 31, 2005, transaction fees were derived from both Archipelago's ArcaEx Equities segment and its ArcaEx Options segment that Archipelago established in the fourth quarter of 2005 with Archipelago's acquisition of the Pacific Exchange. For the year ended December 31, 2005, transaction fees generated by ArcaEx Equities were $415.4 million and transaction fees derived from ArcaEx Options were $9.6 million.

Despite the fact that the total share volume handled on ArcaEx increased during the period, transaction fees generated by ArcaEx Equities decreased $19.1 million, or 4.4%, $434.5 million for the year ended December 31, 2004 to $415.4 million for the year ended December 31, 2005. This primarily resulted from changes in Archipelago's internal match rate and changes in the relative amounts of NYSE-listed, AMEX-listed and Nasdaq-listed securities Archipelago handled on ArcaEx.

The percentage of customer orders matched internally increased to 88.8% for the year ended December 31, 2005 compared to an internal match rate of 86.6% for the year ended December 31, 2004. Archipelago's transaction fee pricing is structured such that routed shares generate greater gross revenue per share than those matched internally. As the number of shares routed out to other market centers declines relative to the overall share volume, Archipelago's transaction revenue growth trails volume growth. Archipelago's transaction fee pricing is also structured such that trades handled by ArcaEx in NYSE-listed securities are charged lower fees than trades consisting of Nasdaq-listed and AMEX-listed

313

securities. Archipelago's trade mix has changed to include more shares of NYSE-listed securities relative to Archipelago's overall share volume handled. For the year ended December 31, 2005, NYSE- listed securities comprised 13.1% of Archipelago's total share volume handled compared to 6.0% for the year ended December 31, 2004.

Market data fees increased from $56.4 million for the year ended December 31, 2004 to $62.0 million for the year ended December 31, 2005, an increase of $5.6 million, or 9.9%. Market data fees derived from trading Nasdaq-listed securities were unchanged at $32.4 million. Market data fees derived from trading Amex-listed securities increased to $24.1 million in 2005 from $21.8 million in 2004. Market data fees derived from trading NYSE-listed securities increased to $4.8 million in 2005 from $2.2 million in 2004. For the year ended December 31, 2005, market data fees generated by ArcaEx Options, which Archipelago acquired in September 2005, were $0.7 million.

Revenues from listing and other fees increased to $6.4 million for the year ended December 31, 2005 from $0.4 million for the year ended December 31, 2004. For the year ended December 31, 2005, ArcaEx Options contributed $5.9 million to other revenues, including OTP fees, exchange floor-based charges and regulatory fees.

Expenses

Expenses (excluding Section 31 fees) increased $45.8 million, or 10.6%, to $476.0 million for the year ended December 31, 2005 from $430.2 million for the year ended December 31, 2004.

As Archipelago's internal match rate increases, Archipelago's liquidity payments increase, while routing charges and clearance, brokerage and other transaction expenses decline. The percentage of customer order volume matched internally on ArcaEx increased to 88.8% (with 11.2% routed to other market centers for execution) for the year ended December 31, 2005 from 86.6% (with 13.4% routed to other market centers for execution) for the year ended December 31, 2004.

Liquidity payments increased to $206.9 million for the year ended December 31, 2005 from $203.5 million for the year ended December 31, 2004, an increase of $3.4 million, or 1.7%. The increase in liquidity payments associated with Archipelago's increased volume and its higher internal match rate was mitigated by a greater contribution of NYSE-listed shares to its total trading volume. Based on its current pricing structure, Archipelago generally does not make liquidity payments for trades in NYSE-listed securities.

Routing charges declined $22.0 million, or 24.8%, to $66.7 million for the year ended December 31, 2005 from $88.7 million for the year ended December 31, 2004. This decline is primarily attributable to Archipelago's increased internal match rate and the resulting reduction in routed volume as well as lower routing costs per share as a result of certain cost management initiatives and changes in trade behavior and product mix. Although Archipelago experienced an increase of 2.9% in its total share volume handled, shares routed out to other market centers declined by 13.5% to 28.4 billion shares for the year ended December 31, 2005 compared to 32.8 billion shares for the year ended December 31, 2004.

Clearance, brokerage and other transaction expenses declined from $13.7 million for the year ended December 31, 2004 to $5.9 million for the year ended December 31, 2005, a $7.8 million, or 56.9%, decrease. Clearance, brokerage and other transaction expenses declined primarily due to the decrease in the number of trades subject to clearing costs due to the lower percentage of orders routed out to other market centers and the reduction of Archipelago's clearing costs following the self-clearing of Archipelago's routing broker and introducing broker businesses. Effective January 2005, Archipelago Securities, Inc. began to clear trades it routed to other market centers for execution. In addition, effective in July 2004, Archipelago Securities, Inc. began to clear trades effected by non-ETP broker-dealer customers accessing ArcaEx through Archipelago's subsidiary, ATS.

314

The increase in other expenses was primarily due to the following:

•: For the year ended December 31, 2005, Archipelago incurred $46.1 million in NYSE merger costs and related executive compensation, including:
•: $28.8 million of compensation expense which was incurred as a result of the acceleration of $20.7 million cash severance payments and vesting of approximately 400,000 restricted stock units to Archipelago's executive officers. These payments and vestings would have occurred in 2006 following the termination of employment agreements or change in control severance agreements after the completion of Archipelago's merger with the NYSE or, in the case of one executive, upon the sale of Wave. However, in 2005, Archipelago terminated the existing agreements and entered into new agreements with its executive officers to accelerate the cash severance payment and vesting of RSUs in furtherance of the following objectives: (i) retain its executive officers (other than the Wave executive) as officers of the combined company following the merger with NYSE; (ii) comply with Section 409A of the Internal Revenue Code (which governs the taxation of arrangements that provide for the deferral of compensation) and (iii) achieve certain significant tax-related cost savings for the combined company;
•: $14.3 million of legal, banking, regulatory and other fees incurred directly in connection with the NYSE merger; and
•: $3.0 million of legal fees incurred in litigation regarding the merger with NYSE brought by certain NYSE members.

Archipelago did not incur these costs in 2004.

•: Other employee compensation and benefits increased by $13.2 million, or 34.4%, to $51.6 million from $38.4 million. The increase was the result of increased staffing and the employee stock-based compensation expense recognized in relation to restricted stock units granted in the 2005. In 2004, long-term incentive compensation consisted of stock options granted at the then estimated fair value of Archipelago's stock for which no compensation expense was recognized due to the absence of intrinsic value. In addition, Archipelago incurred $5.5 million in additional compensation and benefits associated with the employees of ArcaEx Options. Archipelago acquired the operations of ArcaEx Options in September 2005.
•: Depreciation and amortization declined $1.3 million, or 5.7%, to $21.6 million from $22.9 million. The decrease is primarily associated with the accelerated depreciation that Archipelago recognized in the first quarter of 2004 in relation to the retirement of its original trading platform in March 2004, which was partially offset by additional depreciation that it recognized in connection with capital expenditures it made throughout the year ended December 31, 2005.
•: Marketing and promotion increased from $20.1 million to $22.2 million, a $2.1 million, or 10.4%, increase. In 2005, Archipelago accentuated Archipelago's brand recognition advertising efforts.
•: Legal and professional fees increased from $11.1 million for the year ended December 31, 2004 to $12.6 million for the year ended December 31, 2005, a $1.5 million, or 13.5%, increase, including $0.7 million in additional legal and professional expenses incurred by ArcaEx Options, which Archipelago acquired in September 2005.
•: Over the same period, communications and occupancy costs increased by $3.2 million and $2.5 million, respectively. This was mainly due to incremental expenses incurred in connection with Archipelago's operation of a data center in New Jersey (which Archipelago started building in the fourth quarter of 2004) and the operations of ArcaEx Options, which Archipelago acquired in September 2005.

315

•: General and administrative expenses increased $4.9 million, or 43.4%, to $16.2 million from $11.3 million. Insurance premiums and computer maintenance costs increased $1.7 million and $1.9 million, respectively, for the year ended December 31, 2005 compared to the year ended December 31, 2004. In addition, for the year ended December 31, 2005, the newly acquired operations of ArcaEx Options added general and administrative expenses in the amount of $2.2 million.

Interest and Other

Interest and other income and expenses increased $2.9 million to $4.5 million for the year ended December 31, 2005. The increase was primarily driven by higher interest rates earned on Archipelago's invested cash balances.

For the year ended December 31, 2005, Archipelago provided for income taxes at a 42.8% blended tax rate. In the 2004 period, for the income earned from the date of Archipelago's conversion to a Delaware corporation through December 31, 2004, Archipelago provided for income taxes at a 41.5% blended tax rate. Prior to that date, Archipelago was treated as a partnership for federal, state and local income tax purposes. As a result, all items of income, expense, gain and loss were generally reportable on the tax returns of Archipelago's members.

Income from Continuing Operations

As a result of the foregoing, Archipelago reported income from continuing operations of $12.5 million for the year ended December 31, 2005; a decrease of $44.9 million compared to $57.4 million income from continuing operations for the year ended December 31, 2004.

Highlights

For the year ended December 31, 2004, Archipelago's income from continuing operations increased to $57.4 million, a $70.3 million improvement compared to the year ended December 31, 2003. Archipelago's improved results of operations for the period primarily reflect the following principal factors:

•: Increased volume and trading share. While total U.S. market volumes increased 6.9% to 990.5 billion shares traded, Archipelago's total volume traded increased 20.1%, to 140.3 billion shares traded. This increased its share of the trading volume of the total U.S. listed-equity market from 12.6% for 2003 to 14.2% for 2004.

317

•: More liquidity posted on ArcaEx. The percentage of customer orders matched internally increased from 80.6% in 2003 to 86.6% in 2004 and therefore reduced the percentage routed to other market centers, resulting in a change in the amount and mix of the following expenses:
•: liquidity payments increased to $203.5 million, or 41.4% of total revenues in 2004, from $154.2 million, or 37.6% of total revenues in 2003;
•: routing charges declined to $88.7 million, or 18.1% of total revenues in 2004, from $113.8 million, or 27.7% of total revenues in 2003; and
•: clearance, brokerage and other transaction expenses declined to $13.7 million, or 2.8% of total revenues in 2004, from $45.0 million, or 11.0% of total revenues in 2003.
•: Fully-operational ArcaEx. Archipelago realized the benefits of operating ArcaEx as a facility of PCX Equities rather than as an ECN effective April 11, 2003, including increased market data revenues and reduced clearing costs.
•: Continued reduction of clearing expenses. Archipelago reduced clearing costs per trade as a result of both the renegotiation of existing clearing agreements and the transition to self-clearing transactions effected by broker-dealers accessing ArcaEx through Archipelago's subsidiary, ATS.

Total U.S. market volumes in Nasdaq-, NYSE-, and AMEX-listed securities increased by 6.9% from 926.5 billion shares for the year ended December 31, 2003 to 990.5 billion shares for the year ended December 31, 2004. Over the same period, Archipelago's total U.S. market volume increased 20.1% from 116.8 billion shares to 140.3 billion shares. For the year ended December 31, 2004, Archipelago handled 25.3%, 1.8%, and 22.7% of the total trading volume in Nasdaq-, NYSE-, and AMEX-listed equities, respectively, compared to 24.6%, 1.1% and 12.2% for the year ended December 31, 2003.

Revenues

Archipelago's total revenues increased $81.2 million, or 19.8%, from $410.1 million for the year ended December 31, 2003 to $491.3 million for the year ended December 31, 2004. This growth in its total revenues was primarily driven by:

•: a $53.9 million, or 14.2%, increase in transaction fees, reflecting both industry-wide volume growth and Archipelago's expanded trading share, and
•: a $27.4 million, or 94.5%, increase in market data fees, reflecting Archipelago's transition to the ArcaEx platform in April 2003, increased trading volume, and an increase in customer orders matched internally, for which Archipelago receives market data revenues.

Transaction fees increased from $380.6 million for the year ended December 31, 2003 to $434.5 million for the year ended December 31, 2004. The increase was driven by the 20.1% increase Archipelago experienced in transaction volumes and was partially offset by the increase in the percentage of customer shares matched internally.

Market data fees increased from $29.0 million for the year ended December 31, 2003 to $56.4 million for the year ended December 31, 2004, an increase of $27.4 million, or 94.5%. Market data fees derived from trading Nasdaq-listed securities increased from $19.0 million in 2003 to $32.4 million in 2004. Market data fees derived from trading Amex-listed securities increased from $9.3 million in 2003 to $21.8 million in 2004. Market data fees derived from trading NYSE-listed securities increased from $0.7 million in 2003 to $2.2 million in 2004. For the year ended December 31 2004, Archipelago benefited fully from the improved economics of operating ArcaEx as a facility of PCX Equities.

Revenues from listing fees decreased from $0.5 million for the year ended December 31, 2003 to $0.4 million for the year ended December 31, 2004.

318

Expenses

Expenses increased $6.6 million, or 1.5%, to $430.2 million for the year ended December 31, 2004 from $423.6 million for the year ended December 31, 2003.

As Archipelago's internal match rate increases, its liquidity payments increase and routing charges and clearance, brokerage and other transaction expenses decline. The percentage of customer order volume matched internally on ArcaEx increased from 80.6% (with 19.4% routed to other market centers for execution) for the year ended December 31, 2003 to 86.6% (with 13.4% routed to other market centers for execution) for the year ended December 31, 2004.

Liquidity payments increased by $49.3 million, or 32.0%, from $154.2 million for the year ended December 31, 2003 to $203.5 million for the year ended December 31, 2004. Archipelago's increased liquidity payments primarily reflect an increase in the percentage of customer order volume matched internally on ArcaEx and the larger transaction volumes Archipelago achieved in 2004 compared to 2003.

Routing charges declined $25.1 million, or 22.1%, from $113.8 million for the year ended December 31, 2003 to $88.7 million for the year ended December 31, 2004. This decline primarily reflects an increase in the percentage of customer order volume matched internally, partially offset by increased trading volume year-over-year.

Clearance, brokerage and other transaction expenses declined $31.3 million, or 69.6%, from $45.0 million for the year ended December 31, 2003 to $13.7 million for the year ended December 31, 2004. This decline was the result of reduced clearing costs per trade that became effective in November 2003, the migration of trading from the Archipelago ECN to ArcaEx as a facility of PCX Equities in April 2003 (as a result of which Archipelago did not incur clearing charges for trades executed internally), and a decrease in the relative number of trades subject to clearing costs due to the lower percentage of orders routed out. In addition, effective in July 2004, Archipelago began to self-clear trades effected by non-ETP broker-dealer customers accessing ArcaEx through Archipelago's subsidiary, ATS, which contributed to the reduction of Archipelago's clearing costs.

Clearance, brokerage and other transaction expenses for the year ended December 31, 2003 included the following:

•: $4.5 million in costs related to fees charged by Spear, Leeds & Kellogg L.P., a subsidiary of The Goldman Sachs Group, Inc., under Archipelago's service bureau agreement with them for the development, operation, management and support services provided to the REDIBook ECN in connection with the integration of the REDIBook ECN into the Archipelago system. Archipelago did not incur these charges in 2004 due to the migration of trading of Nasdaq-listed securities from the Archipelago ECN to ArcaEx in April 2003.
•: $7.0 million of bad debt expense for accounts receivable balances that Archipelago deemed uncollectible. For the year ended December 31, 2004, Archipelago took back into income approximately $0.9 million as a result of improved collections, which provided for a $7.9 million decrease of clearing, brokerage and other transaction expenses year-over-year.

The increase in other expenses was primarily due to the following:

•: Employee compensation and benefits increased $2.3 million, or 6.4%, to $38.4 million from $36.1 million primarily as a result of increased staffing.
•: Depreciation and amortization declined by $3.0 million, or 11.6%, to $22.9 million from $25.9 million. The decrease was primarily associated with the accelerated depreciation Archipelago recognized for the period from June 2003 to March 2004 in relation to the retirement of its original trading platform. This was partially offset by additional depreciation Archipelago recognized in

319

connection with capital expenditures Archipelago made throughout the year ended December 31, 2004.

•: Marketing and promotion increased from $12.0 million to $20.1 million from $8.1 million primarily as a result of the brand recognition advertising campaign Archipelago launched in September 2004.
•: Legal and professional fees increased by $2.8 million, or 33.7%, to $11.1 million from $8.3 million in relation to additional expenses incurred as a public company, including increased board of directors and audit fees.
•: General and administrative expenses increased by $1.4 million, or 14.1%, to $11.3 million from $9.9 million also in relation to additional expenses incurred as a public company, including directors and officers' insurance premiums. This was partially offset by reduced computer lease expenses.

Interest and Other

Interest and other income and expenses increased by $1.0 million to $1.6 million for the year ended December 31, 2004, compared to $0.6 million for the year ended December 31, 2003. This was due to increased average cash and cash equivalent balances and higher interest rates earned on those balances.

Income Tax Provision

For the income earned from the date of Archipelago's conversion to a Delaware corporation through December 31, 2004, Archipelago provided for income taxes at a 41.5% blended tax rate. In 2003, Archipelago was treated as a partnership for federal, state and local income tax purposes. As a result, all items of income, expense, gain and loss were generally reportable on the tax returns of Archipelago's members.

Income (Loss) from Continuing Operations

As a result of the foregoing, Archipelago reported income from continuing operations of $57.4 million for the year ended December 31, 2004, which represents an increase of $70.3 million compared to the loss from continuing operations of $12.9 million for the year ended December 31, 2003.

Deemed Dividend on Convertible Preferred Shares

Upon the conversion of redeemable preferred shares into shares of common stock in connection with of Archipelago's IPO, Archipelago issued approximately 717,000 additional shares of common stock attributable to a beneficial conversion feature included in the previously issued redeemable preferred interest. The $9.6 million intrinsic value of such shares was deemed a dividend on convertible preferred shares, which was reported after net income to reach net income attributable to common stockholders.

Net Income Attributable to Common Stockholders

Archipelago reported net income attributable to common stockholders of $59.3 million for the year ended December 31, 2004; an increase of $57.5 million compared to net income of $1.8 million for the year ended December 31, 2003.

Liquidity and Capital Resources

Historically, Archipelago's primary sources of liquidity were cash provided by operations and proceeds generated from the sale of its common equity and preferred shares. On August 19, 2004, Archipelago completed the sale of 6,325,000 shares of common stock at $11.50 per share in its IPO, for which it received net proceeds of $67.6 million. Archipelago incurred approximately $6.8 million in expenses

320

related to its IPO. Certain former members of Archipelago Holdings LLC sold another 6,325,000 million shares to the public, for which Archipelago received no proceeds.

On September 26, 2005, Archipelago completed the acquisition of PCX Holdings and its subsidiaries for a total purchase price of approximately $94.0 million consisting of a $90.9 million cash payment to PCX Holdings stockholders and certain PCX Holdings employees, and direct costs of acquisition of $3.1 million. The $90.9 million cash payment represented the total dollar value of 1,645,415 shares of Archipelago common stock held by PCX Holdings at the time of the closing, or $66.3 million, plus $24.6 million.

In connection with its merger with NYSE, at closing, Archipelago maintained a minimum $120.0 million net cash balance, as defined. For the year ended December 31, 2005, Archipelago incurred $46.1 million in NYSE merger costs and related executive compensation, including (i) $28.8 million of compensation expense ($21.3 million in cash and $7.5 million as a non-cash charge) incurred as a result of the acceleration of certain payments and vesting of restricted stock units to Archipelago's executive officers that would have occurred in 2006 following the termination of employment agreements or change in control severance agreements after the completion of Archipelago's merger with the NYSE or, in the case of one executive, upon the sale of Wave, (ii) $14.3 million of legal, banking, regulatory and other fees incurred directly in connection with the NYSE merger, and (iii) $3.0 million of legal fees incurred in connection with litigation matters related to the merger of the NYSE and Archipelago brought by certain NYSE members.

Archipelago's principal liquidity requirements have historically been for working capital, capital expenditures and general corporate purposes. Archipelago's capital expenditures have historically related primarily to developing its trading platforms, which included investments in software development and hardware, as well as building its data centers.

As of December 31, 2005, Archipelago had $145.3 million of cash and cash equivalents (including cash from discontinued operations of $11.0 million). For the year ended December, 2005, Archipelago provided cash of $91.5 million from the operating activities of its continuing operations, consisting of income from continuing operations of $12.5 million and the $79.0 million net effect of non-cash items and changes in its working capital. Archipelago used $118.4 million in investing activities of its continuing operations to acquire PCX Holdings and its subsidiaries and to purchase fixed assets and develop software. In addition, Archipelago's continuing operations provided cash from financing activities of $16.0 million primarily in relation to a $24.0 million capital contribution from the discontinued operations of Wave, which was partially offset by $7.8 million Archipelago spent repurchasing shares of its common stock.

Archipelago's broker-dealer subsidiaries are subject to regulatory requirements intended to ensure their respective general financial soundness and liquidity, which require that they comply with certain minimum capital requirements. These regulations, which differ in the United States, the United Kingdom and Canada—the three countries in which Archipelago's broker-dealer subsidiaries do business—generally prohibit a broker-dealer subsidiary from repaying borrowings from Archipelago or its affiliates, paying cash dividends, making loans to Archipelago or its affiliates or otherwise entering into transactions that would result in a significant reduction in its regulatory net capital position without prior notification or approval of its principal regulator. Archipelago's capital structure was designed to provide each of its subsidiaries with capital and liquidity consistent with its business and regulatory requirements.

Off-Balance Sheet Arrangements

In November 2004, pursuant to a lease agreement, Archipelago applied for a $1.2 million irrevocable standby letter of credit, which has periodic reductions to the amount required to be maintained until expiration in July 2015. In connection with this letter of credit, Archipelago entered into a compensating balance agreement with its bank for one and one-half times the amount of the letter of credit. The beneficiary of this letter of credit is the landlord of certain office space leased by Archipelago in New York.

Critical Accounting Policies

Archipelago management's discussion and analysis of Archipelago's financial condition and results of operations is based on its financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements required Archipelago to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. Archipelago historically reviewed its estimates on an on-going basis. Archipelago based its estimates on historical experience and on various other assumptions that it believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. While Archipelago's significant accounting policies are described in more detail in the notes to its financial statements, Archipelago believes the following accounting policies to be critical to the judgments and estimates used in the preparation of its financial statements.

Revenue Recognition

Archipelago recognized revenue in the form of transaction fees paid by customers for trade execution on the Archipelago system, whether the trade is executed internally or routed out to an external market center. Archipelago also simultaneously recognized an expense, in the form of either a liquidity payment or a routing charge, paid to the liquidity provider or the external market center, as the case may be. Archipelago recognized these fees and expenses on a gross basis in its consolidated financial statements in accordance with Emerging Issues Task Force ("EITF") Issue No. 99-19, "Reporting Revenue Gross as a Principal versus Net as an Agent." Archipelago's application of EITF Issue No. 99-19 included an evaluation of a number of factors deemed relevant by management in making its determination with respect to gross versus net reporting of revenue.

Archipelago also earned market data fees from the sale of market data, and in turn rebated a portion of those fees to Archipelago's customers. In accordance with EITF Issue No. 99-19, Archipelago recognized these fees as revenue net of the rebates provided to its customers in its consolidated financial statements. Archipelago estimated the market data fees it earned each quarter based on the number of transactions executed on the Archipelago system in that quarter that qualify for payment under the various market data plans.

322

Archipelago's listing fees consisted of original listing fees, fees payable in connection with the listing of additional shares of equity securities and annual listing fees. Archipelago recognized annual listing fees ratably over the following twelve-month period. Archipelago recognized initial listing fees and additional share listing fees over five-year estimated service periods.

Archipelago's other revenues primarily consisted of regulatory and registration fees including agent annual registration and new application and transfer fees from parties that have equities or options trading privileges on the Pacific Exchange. Regulatory and registration fees were billed and collected by the National Association of Securities Dealers (the "NASD"). The registration fee was billed annually in advance and remitted to Archipelago before the start of the effective year. Archipelago recognized the annual registration fee ratably over the related twelve-month period. New registration and transfer application fees were remitted monthly to Archipelago and recognized in the year received.

Archipelago paid SEC fees pursuant to Section 31 of the Securities Exchange Act of 1934. These fees were designed to recover costs incurred by the government for the supervision and regulation of securities markets and securities professionals. Archipelago, in turn, collected activity assessment fees from ETP and OTP holders trading on ArcaEx and the Pacific Exchange, respectively, and paid Section 31 fees to the SEC based on fee schedules determined by the SEC. Fees received were included in cash and cash equivalents at the time of receipt, and, as required by law, the amount due to the SEC was recorded as an accrued liability and remitted semiannually.

Following the September 26, 2005 acquisition of PCX Holdings, Archipelago recorded activity assessment fee revenue and Section 31 fees expense gross on its consolidated statement of operations as Archipelago bore the credit risk associated with the collection of these fees, while maintaining similar treatment within the consolidated statement of financial condition.

Goodwill and Indefinite-Lived Intangible Assets

As of December 31, 2005, Archipelago had approximately $240.6 million in goodwill and intangible assets. Under SFAS No. 142, "Goodwill and Other Intangible Assets," management was required to perform a detailed review at least annually of the carrying value of Archipelago's intangible assets, which included goodwill and Archipelago's national securities exchange registration. In this process, management was required to make estimates and assumptions in order to determine the fair value of Archipelago's assets and liabilities and projected future earnings using various valuation techniques, including a discounted cash flow model. Management used its best judgment and information available to it at the time to perform this review, as well as the services of an expert valuation specialist. Because management's assumptions and estimates were used in the valuation, actual results may differ. If management determines that the fair value of the intangible assets is less than their carrying value, an impairment loss would be recognized in an amount equal to the difference between the fair value and the carrying value.

Provision for Doubtful Accounts

Archipelago evaluated the collectibility of accounts receivable based on the financial condition of its customers, the length of time a receivable was past due, its historical experience with the particular customer and the likelihood of projected payments. If Archipelago knew of a customer's inability to meet its financial obligations, it recorded a specific provision for doubtful accounts for estimated losses resulting from the inability of that customer to make payments. The amount of the provision was then charged against the amounts due to reduce the receivable to the amount Archipelago reasonably believes would be collected. Due to changing economic, business and market conditions, Archipelago reviewed the provision monthly and made changes to the provision as appropriate.

323

Stock-Based Compensation

Archipelago elected to follow APB No. 25, "Accounting for Stock Issued to Employees," and related interpretations in accounting for its employee stock options. Under APB No. 25, Archipelago recorded compensation expense equal to the difference between the exercise price of the stock option and the fair market value of the underlying stock as of the measurement date. For disclosure purposes only, Archipelago also estimated the impact on its net income of applying the fair value method of measuring compensation cost on stock options with the fair value determined under the minimum value method as provided by SFAS No. 123, "Accounting for Stock-Based Compensation" as amended by SFAS No. 148, "Accounting for Stock-Based Compensation—Transition and Disclosure."

In December 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No. 123(R) (revised 2004), "Share-Based Payment," requiring that compensation cost associated with share-based payment transactions be recognized in financial statements. Statement No. 123(R) replaces the former SFAS No. 123 and supersedes APB No. 25. Archipelago adopted SFAS No. 123(R) on January 1, 2006 using the modified-prospective method. For the year ending December 31, 2006, management anticipates that Archipelago will recognize a pre-tax expense of approximately $2.0 million in connection with share-based payment transactions recorded under SFAS No. 123(R).

Related-Party Transactions

Archipelago has entered into significant transactions with its affiliates in the normal course of business. In the opinion of management, transactions and agreements with affiliates are made at prevailing market rates, terms and conditions, and do not involve more than the normal risk of collectibility or present other unfavorable features. For a discussion of transactions with Archipelago's affiliates, see Archipelago's Consolidated Financial Statements and Note 10 thereto included elsewhere in this prospectus.

Software Development

Archipelago accounts for software development costs under SOP 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use," and other related guidance. Archipelago expenses software development costs incurred during the preliminary project stage, while it capitalizes costs incurred during the application development stage, which includes design, coding, installation and testing activities. Amortization of capitalized software development costs is computed on a straight-line basis over the software's estimated useful life, generally three years.

Income Taxes

The objectives of accounting for income taxes are to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in an entity's financial statements or tax returns. Significant judgment is required in assessing the future tax consequences of events that have been recognized in Archipelago's financial statements or tax returns. Fluctuations in the actual outcome of these future tax consequences could have a material impact on Archipelago's financial position or results of operations.

Other Significant Accounting Policies

Other significant accounting policies not involving the same level of measurement uncertainties as those described above are nevertheless important to an understanding of Archipelago's consolidated financial statements. Policies related to certain accounting policies require difficult judgments on complex

324

matters that are often subject to multiple sources of authoritative guidance. For a discussion of Archipelago's other significant accounting policies, see Archipelago's Consolidated Financial Statements and Note 2 thereto included elsewhere in this prospectus.

Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As of December 31, 2005, an evaluation was carried out under the supervision and with the participation of Archipelago's management, including Archipelago's chief executive officer and chief financial officer, of the effectiveness of the Archipelago's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based upon that evaluation, Archipelago's chief executive officer and chief financial officer concluded that, as of December 31, 2005, these disclosure controls and procedures were effective.

INFORMATION ABOUT EURONEXT

Overview

Euronext is the first genuinely cross-border exchange organization. Created in 2000 through the merger of the Paris, Amsterdam and Brussels exchanges, after a series of acquisitions Euronext now provides services for regulated cash and derivatives markets in Belgium, France, the UK (derivatives only), the Netherlands and Portugal. It also has (jointly with Borsa Italiana) a major stake in Società per il Mercato del Titoli di Stato (or MTS), the leading electronic market for European wholesale fixed income securities, and sells software and IT trading solutions through its subsidiary GL TRADE, a leading provider of front to back-office trading, clearing and settlement solutions, and Atos Euronext Market Solutions, an associate held 50/50 by Atos Origin S.A. and Euronext under the control of Atos Origin S.A.

In 2005, Euronext was Europe's largest stock exchange organization in terms of the volume and value of transactions processed through the central order book, the second largest derivatives exchange in Europe in terms of the volume of transactions processed and the second largest derivatives exchange worldwide in terms of the value of transactions processed per day. Thirty-two of Europe's one hundred largest companies by market capitalization as at June 30, 2006 were listed on Euronext and Euronext was the leading European market for initial public offerings in 2005 by offer value. Euronext had 2,302 employees at the end of 2005 (including 1,133 GL TRADE employees and Euronext's share of MTS' employees).

Since its creation, Euronext has fostered the consolidation of European financial markets by integrating local exchanges across Europe in order to provide users with a single market that is broad, highly liquid and cost-effective. After the initial three-way merger of the Paris, Amsterdam and Brussels exchanges, Euronext acquired the London-based derivatives market LIFFE (London International Financial Futures and Options Exchange), and merged with the Portuguese exchange BVLP (Bolsa de Valores de Lisboa e Porto). Euronext integrated its constituent markets based on a horizontal market model designed to generate synergies by incorporating the individual strengths and assets of each local market. This business model covers technological integration, the reorganization of activities into cross-border, streamlined strategic business units (or SBUs), and the harmonization of market rules and the regulatory framework.

Following successful completion in 2004 of a four-year migration, Euronext's cash and derivatives markets operate on single, harmonized IT platforms, NSC (nouveau système de cotation) for cash trading and LIFFE CONNECT® for derivatives. As a result, every market participant now has a single point of access to trading cash and derivatives instruments, respectively. This has also helped to enhance the visibility of listed companies, reduce average trading fees and facilitate the comparison of investments. IT services, including the management of its trading platforms, are provided to Euronext by Atos Euronext Market Solutions, which is a leading global provider of technology services to the capital markets.

The integration of Euronext's trading platforms has been fostered and accompanied by regulatory harmonization. A single rulebook governs trading on Euronext's cash and derivatives markets, respectively, containing a set of harmonized rules and a set of exchange-specific rules. Regulation of Euronext and its constituent markets is conducted in a coordinated fashion by the respective national regulatory authorities pursuant to memoranda of understanding relating to the cash and derivatives markets.

Euronext operates as a fully integrated organization of multinational teams based on three cross-border, product-based strategic business units, which are assisted by cross-border central support departments that provide services to the entire group. Each of the strategic business units (Cash Trading and Listing, Derivatives Trading, and Information Services) operates under a single chain of command, and is responsible for activities and staff at all of Euronext's markets, irrespective of their actual geographic location. The central support departments are responsible for various functions (finance;

326

human resources; legal affairs, regulation, compliance and European affairs; corporate information systems; corporate strategy, etc.) and coordinate matters between the strategic business units.

Euronext's customers are comprised mainly of exchange organization members and financial institutions that have direct access to trading on Euronext's markets, companies whose securities are listed on Euronext's markets and that seek to raise capital, institutional and retail investors who trade on Euronext's markets, organizations that use Euronext's technologies and services and users of financial information. As of September 1, 2006, there were 240 members of Euronext's cash markets and 848 members of its derivatives markets.

Clearing and settlement of trades on Euronext's markets is effected by the LCH.Clearnet Group Limited (LCH.Clearnet) and Euroclear, respectively, except for Euronext Lisbon where settlement is currently effected by Euronext's wholly owned subsidiary, Interbolsa. LCH.Clearnet and Euroclear provide these services pursuant to contractual arrangements with Euronext, which also has a substantial minority shareholding in the former and a small shareholding in the latter. Euronext previously owned its clearing and settlement service providers but gradually divested them through the creation of LCH.Clearnet, which resulted from the merger of Euronext's former subsidiary Clearnet S.A. and the London Clearing House Limited, and the sale to Euroclear of its national central securities depositories (Sicovam, Necigef and CIK) other than Interbolsa.

Business Segments

Euronext has seven principal cross-border business segments, as summarized in the table below. Euronext manages its primary business segments on the basis of three cross-border, product-based strategic business units (Cash Trading and Listing, Derivatives Trading and Information Services).

Cash Trading

General

Euronext is Europe's largest cash market based on average daily trades and average daily turnover. During 2005 and the first half of 2006, on an average day, 632,000 and 915,000 trades, respectively, valued at €7.1 billion and €10.2 billion, respectively, were executed on Euronext exchanges. The total number of trades in all cash products amounted to 162 million during 2005 and 116 million during the first half of 2006.

The following tables set forth comparative data regarding cash trading (total market capitalization of listed companies and number of trades conducted via the central order book) on different European exchanges during 2005.

Using Euronext's electronic trading platform, NSC (nouveau système de cotation), Euronext's members enter trades into a cross-border central order book and have access to equities with a total market capitalization of €2,500 million as of June 30, 2006 issued by issuers in 23 countries. The cash trading business unit comprises trading in equity securities and other cash instruments including funds, bonds, warrants, trackers and structured funds. Euronext generates cash trading revenues by collecting fees charged based on trades made, by number and value. Euronext also charges its members connection fees for access to its NSC trading platform (€10 million in 2005). In 2005, Euronext generated cash trading revenues of €215.7 million, or 22.4% of its total revenues.

Trading Platform and Market Structure

Trading Platform

Cash trading on Euronext's markets in Amsterdam, Brussels, Lisbon and Paris takes place via the NSC system, Euronext's common electronic trading platform for the cash market. The NSC system was originally the trading platform for Euronext Paris; Euronext Brussels and Euronext Amsterdam migrated to NSC in 2001 and Euronext Lisbon migrated in 2003. The NSC system is a fully automated electronic trading platform that allows trading members either to route their clients' orders electronically or to enter orders manually into computer workstations installed on their premises and linked to the NSC system. The NSC system maintains an order book for every traded security, in which it matches buy and sell orders electronically. After a trade has been executed, trade confirmations are sent electronically in real time to the trading members.

328

Customized versions of the NSC system, which Atos Euronext Market Solutions supplies to other stock exchanges, are currently used by 15 exchanges worldwide (including Euronext's four cash markets), more than any other trading platform. One of the strengths of the NSC system is its ability to process the wide variety of order types permitted under Euronext's trading rules, as further described below. The NSC system also includes the ability to combine most of these order types and to execute large orders within a single order book, which allows trading members to adapt their trading strategies and also to increase liquidity. Another strength of the NSC system is its scalability. Between 2003 and 2005, technology enhancements allowed Euronext to expand the order handling capacity of the NSC system by more than three times and to improve response times by more than 50%. Enhancements completed or planned for 2006 are expected to increase order handling capacity by an additional 300%.

Harmonized Rulebook and Market Model

Cash trading on Euronext is governed both by a single harmonized rulebook for trading on each of Euronext's markets in Paris, Amsterdam, Brussels, and Lisbon and by the various non-harmonized Euronext Rulebooks containing local exchange specific rules. Euronext's trading rules provide for an order-driven market using an open electronic central order book for each traded security; various order types and automatic order matching; and a guarantee of full anonymity both for orders and trades. See "Regulation—European Regulation." The main features of the Euronext market model include:

•

Order matching and execution. Trading on Euronext takes place on the basis of two trading mechanisms:

•: Continuous trading. During continuous trading, each incoming order is checked immediately for possible execution against orders already in the central order book to determine whether the new order can be matched against an already-recorded order. Orders in the central order book are executed according to price/time priority at the limit price of orders then contained in the central order book. Continuous trading is advantageous only if there are sufficient orders in the central order book. Accordingly, under Euronext's trading rules, financial instruments may be traded continuously only if they meet specified liquidity criteria or are traded with the support of a liquidity provider.
•: Auction mechanism. Under the auction mechanism, orders are not executed immediately, but instead are recorded and accumulated without execution until prices are determined by auction at set times. The auction price is the price that produces the highest executable volume. For securities in which the auction mechanism is the sole basis of trading, the auction method increases the likelihood of matching orders by concentrating orders at a particular moment in time. Under Euronext's trading rules, less liquid securities are required to be traded in auctions only.

•

Liquidity providers. For certain segments, Euronext's trading rules allow for, and in some cases require, the involvement of liquidity providers. Liquidity providers are trading members that agree with Euronext to enter buy and sell orders for their own account in the central order book, with a view to enhancing the liquidity of a given financial instrument. These orders must meet minimum size requirements and the spread (the difference between the prices of buy and sell orders) may not exceed a pre-determined level.

•

Order types. Euronext's trading rules permit a wide variety of order types, from "market" orders (orders to execute trades at any price in the central order book until all orders on the opposite side have been executed) and "limit" orders (orders to execute trades at or above (in the case of sell orders) or at or below (in the case of buy orders) certain specified price limits) to more complex orders such as "iceberg" orders and "stop loss" orders (orders stored and automatically triggered by the system when specific prices are reached). Additional order types supported include "fill-and-kill," "fill-or-kill," "minimum-quantity," "must-be-filled," "market-to-limit"/"market-on-opening,"

329

"stop-limit" and "stop-loss." Certain of these order types add additional liquidity to the market. For example, the ability to place iceberg orders (which are large orders displayed in smaller parts) allows investors that do not wish to reveal the exact volume of securities they wish to buy or sell to nevertheless place their orders in order to keep their price privacy in the order book. It is unlikely that such orders would be placed if the full volume of the orders were revealed, due to the effect that such information might have on the market (the market moves against the large order). Euronext also offers the possibility to match, directly in the order book, guaranteed cross-trades, i.e., the possibility to organize a trade between two internal accounts (house or client orders).

•: Trading outside the central order book. Euronext's trading rules permit market participants to execute certain trades, including block trades or VWAP trades, outside the central order book. Off-order book trading can facilitate trades that are particularly large or enhance off-hours trading capabilities. Using this option, market participants can carry out mutually agreed trades that do not have to be routed through the central order book and that can be carried out at any time of day. The Euronext rulebook specifies minimum transaction sizes for block trades as well as price ranges relative to specified prices displayed in the central order book. Although executed off-order book, these trades executed in accordance with the Euronext rulebook are considered to be executed on one of Euronext's regulated markets and are required to be immediately reported using Euronext's trade confirmation system.
•: Trading safeguards. To avoid undesired volatility, if any order entered in the central order book would cause the price of any security to cross a specified threshold, the NSC system triggers automatic trading interruptions to ensure fair and orderly trading. In continuous trading, the member that entered the order that triggered the trading suspension is provided a time window within which it can confirm the pending balance of its order. Absent such confirmation, the balance of the trade is cancelled.

Products Traded

Euronext's cash trading markets accommodate trading in a wide variety of cash instruments, including:

•: Equities. Euronext is Europe's largest cash equities market in terms of average daily trading volume. During the first six months of 2006, on an average day, 873,736 shares, valued at €9.9 billion, were traded on Euronext. As of June 30, 2006, customers using Euronext's NSC trading platform could execute trades in the stock of 1,224 companies located in 23 countries.
•: Funds. As of June 30, 2006, members could execute trades in over 287 investment funds.
•: Trackers. Euronext has developed a special product segment, NextTrack, that is dedicated to trading in trackers, also known as Exchange Traded Funds, or ETFs. As of June 30, 2006, members could execute trades in 121 trackers linked to 75 different indices. Trackers are open-ended investment funds that track an index or replicate the performance of an index or a basket of shares, and are traded on Euronext in the same way as ordinary financial instruments. Originally focused on European large caps including geographical and sector indices, the range has gradually been extended to other asset classes such as bonds and real estate. Different investment styles have also been integrated with the addition of trackers on small and mid-caps and social responsibility indices, along with new geographical regions including Japan and emerging markets.
•: Structured funds. In 2005, Euronext listed its first structured funds, which allow investors to combine management techniques such as leverage and guaranteed principal with the benefits of listing. As of June 30, 2006, members could execute trades in seven structured funds linked to three different indices, which form part of the NextTrack segment.

330

•: Warrants & Certificates. Via NextWarrants, Euronext's market segment dedicated to warrants, warrants on over 250 underlying instruments were available as of June 30, 2006. NextWarrants trades are executed on a specific module of the NSC trading system, NSC-Warrants, a dedicated platform that takes into account the specific market structure of warrants.
•: Bonds. A broad selection of bonds is traded on the Euronext platform, such as corporate (including convertible) bonds and government bonds. As of June 30, 2006, 3,413 bonds were listed.

Trading Members

As of June 30, 2006, 240 members from 14 countries were eligible to trade on Euronext's cash markets. The majority of the members are based in Euronext's marketplaces, while remote members are mostly found in the UK and Germany. Between 2002 and 2005, the share of cross-border trading on Euronext marketplaces (i.e., trades originating from members not located in the corresponding country) increased from 9.0% to 23.0%. The following table shows the evolution in cross-border trading between 2002 and 2005:

Market Position and Competition

Euronext provides cash equity trading services in respect of Belgian, Dutch, French and Portuguese-listed equities, and in respect of such services does not face significant competition from any other stock exchange. Inter-exchange competition is marginal and inherently limited by the circumstance that trading in individual equities is typically concentrated on a single exchange, generally the domestic exchange on which the equity was initially listed.

While the competitive constraint exercised by other exchanges is limited, Euronext faces significant and growing competition from trading services provided by a wide array of alternative off-exchange trading venues. Euronext faces competition from large brokers and customers, who have the ability to divert trading volumes from Euronext in one of two ways. First, large banks may assume the role of principal and act as counterparty to orders originating from retail investors, thus "internalizing" order flow that would otherwise be traded on an exchange. Second, banks and brokers may enter into bilateral trading arrangements by matching their respective order flows, thus bypassing the trading platform Euronext provides. Furthermore, Euronext competes with an array of automated multi-lateral trading platforms, such as ITG/Posit, E-crossnet, and Instinet CBX. The competitive significance of these various alternate trading venues is likely to increase substantially in the future, with the regulatory environment in Europe becoming more hospitable to off-exchange trading as a result of the reforms contained in MiFID. MiFID

331

will come into effect on November 1, 2007, although individual EU Member States are required to incorporate MiFID into their domestic legal regimes by January 31, 2007. See "Risk Factors—Risks Relating to NYSE Euronext's Business—The implementation of the European Directive on Markets in Financial Instruments, or MiFID, may accelerate the development of off-exchange trading in Europe, which may harm NYSE Euronext's competitive position."

Listing

General

Euronext's listing business manages the admission of new securities to its markets. As of June 30, 2006, 32 of the top 100 European companies by market capitalization (FTSEurofirst 100 index) were listed on Euronext. In 2005, €17.2 billion in offering proceeds was raised in 78 IPOs on Euronext, including those of EDF S.A. and GDF S.A., which were two of the largest IPOs worldwide in 2005.

Euronext's exchanges list a wide variety of securities, including non-U.S. and domestic equity securities, convertible bonds, warrants, trackers and debt securities, including corporate and government bonds. Representatives of the listing business work with domestic and international candidates as well as their financial intermediaries and manage their files until the first day of listing. Once a security has been admitted to listing, Euronext handles all of the corporate events related to the security and produces notices for the market.

At the end of 2005, 1,259 companies were listed on Euronext, of which 966 were based in one of Euronext's home markets. The remaining 293 listed companies are registered elsewhere and chose Euronext as their primary European market for raising capital. Intent on becoming the gateway to the eurozone, Euronext is focused on increasing its share of these "non-domestic" listings in the future.

Euronext generates listing revenues when securities are admitted to listing for the first time. It also generates revenues by charging admission fees to companies that wish to issue additional shares or other financial instruments, and by charging annual listing fees to companies listed on its markets. In 2005, Euronext generated €63.1 million in listing revenue, or 6.6% of total revenues.

Organization of Listed Companies

EU Regulated markets: Eurolist

In 2005, Euronext created a single list, Eurolist by Euronext, to encompass all of its regulated national markets. The three main markets of Paris (Premier Marché, Second Marché and the Nouveau Marché) were merged into Eurolist by Euronext in February, followed by corresponding steps in Amsterdam, Brussels and Lisbon in April. Issuers still choose an initial entry point (Paris, Amsterdam, Brussels or Lisbon) for the listing of their securities, which has important regulatory consequences, but once admitted these securities are then accessible from all Euronext markets through Eurolist.

As part of their admission to Eurolist by Euronext, all companies are placed in market segments based on their market capitalization, in order to enable investors to distinguish easily between large, medium-sized and small companies (capitalizations of over €1 billion (Segment A), between €150 million and €1 billion (Segment B), and below €150 million (Segment C), respectively).

Sector classifications

Every company listed on Euronext (and other financial markets) is assigned a standardized sector classification based on its activities. In 2005, a new classification system, the Industry Classification Benchmark, was launched by the FTSE and Dow Jones Indices to replace the FTSE Global Classification System. The new Industry Classification Benchmark system came into force on Euronext's markets on January 2, 2006 following a transitional period.

332

Market segments

Euronext offers listed companies that meet specified criteria the opportunity to become members of its market segments, primarily for marketing purposes. The market segments are separate from the industrial sector classification received by each listed company. Listed companies are not required to be included in one of Euronext's market segments, but may opt in through an inclusion agreement. These market segments include NextEconomy® (which consists of companies whose core business lies in new technologies) and NextPrime® (which consists of companies from traditional sectors of the economy). To be admitted to membership in the NextEconomy and NextPrime market segments, an issuer must meet specified financial transparency requirements (including a requirement to publish accounts in English and in accordance with International Financial Reporting Standards (or IFRS)) and satisfy (e.g., via a market maker) the liquidity conditions to be eligible for continuous trading. Euronext actively seeks to raise the profile of companies choosing to be admitted to NextPrime and NextEconomy through special indices, a dedicated section of its website and other tools such as special road shows and events.

Indices

Euronext compiles and promotes indices to enhance the profiles of issuers listed and products traded on its exchanges and to increase trading revenues, in particular national indices. See "Information About Euronext—Information Services."

Alternext and other tailored solutions for SMEs

In May 2005, Euronext launched Alternext Paris, an innovative market tailored to the needs of small to medium-sized companies, or SMEs, which was followed by the announcement of approval of Alternext Amsterdam on May 30, 2006 and the launch of Alternext Brussels in June 2006. Alternext is governed by the respective local legal framework and a body of rules laid down by the market operator, Euronext, and applicable to all participants. It is not a regulated market, as defined by MiFID, but provisions equivalent to those set forth in the European Market Abuse Directive nevertheless apply to trading on Alternext for the benefit of investors. From Alternext's launch in May 2005 through June 30, 2006, 48 companies were listed on Alternext. These companies do business in a variety of sectors, ranging from software and internet services to electronics and real estate. Key features of the Alternext market include:

•: Alternext is open to SMEs from all sectors of the economy, so long as they can present at least two years of financial statements.
•: Companies listing on Alternext can make their initial listing in connection with a public offering pursuant to a prospectus approved by the competent EU authority. They can also directly list their shares on Alternext in connection with a private placement via an information document, so long as the private placement was made in the two preceding years of an initial listing and involved placing at least €5 million with at least five qualified investors.
•: For a public offering, the minimum free float after listing is only €2.5 million. For a private placement, the minimum free float after listing is €5 million.
•: Companies seeking a listing on Alternext must engage the services of a listing sponsor, both in the run-period prior to initial listing and while they remain a listed company. The listing sponsor declares to Euronext that it will ensure that listed companies meet their disclosure requirements for Alternext and guides and counsels the listed company and in France the listing sponsor makes a contractual commitment to Euronext to ensure that listed companies meet their disclosure requirements.
•: Companies listing on Alternext have greater flexibility in their choice of accounting standards and are subject to less extensive ongoing post-listing reporting requirements than companies listing on

333

Eurolist. For a description of these requirements see "Information About Euronext—Listing—Listing Standards."

Other efforts to promote trading in the securities of SMEs include:

•: Euronext introduced small and mid-cap expert status in 2005 to promote analysis of SMEs (segments B and C of Eurolist) and enhance their liquidity. Euronext grants small and mid-cap expert status to brokers meeting specific research, marketing and promotion requirements relating to small and mid-caps.
•: In 2005, Euronext launched a new line of indices especially for SMEs in Amsterdam, Brussels and Paris.

Listing Standards

Through close cooperation with the regulators of the financial markets in each of the EU member states where Euronext operates, Euronext has adopted a harmonized rulebook that sets out a unified set of listing standards with which issuers must comply, regardless of which of Euronext's markets (Paris, Brussels, Amsterdam, Lisbon) is chosen as the entry point. These harmonized listing standards and the local applicable rules from Euronext Rulebook II set forth the criteria required for the listing of securities on Euronext's exchanges, as well as ongoing requirements, particularly with respect to financial reporting. The following chart summarizes certain of the applicable listing standards.

	EUROLIST	ALTERNEXT
Nature of Market	EU Regulated Market	Alternext-Regulated Market
Target Issuers	Blue Chip and Mid-Cap	SMEs
Initial Listing Transaction	Public offering	Public offering	Private Placement
Offer Document	Prospectus	Prospectus	Offering Circular
Free float requirement	25% of outstanding securities; or 5% of capital amounting to at least €5 million	At least €2.5 million	At least €5 million
Sponsor	Yes	Yes
Listing Agent	Yes	No
Years of Accounts Required	3 years audited, half year interims (reviewed) required if more than 9 months after end of fiscal year	2 years, most recent year audited, half year interims required if more than 9 months after end of fiscal year
Accounting Standards	IFRS	Local GAAP permitted
Shareholder reporting thresholds	Varies per country	50%, 95%
Ongoing Financial Reporting	Annual audited accounts, reviewed six month accounts	Annual audited accounts, six month unaudited accounts (no review necessary)

Each year, a number of companies cease to be listed on Euronext, as a result of both normal corporate actions, such as mergers and acquisitions, and a desire on the part of some companies, in light of continued European integration, to reduce the number of exchanges on which they are listed given the related regulatory commitments. New listings on Euronext have helped to offset partially these delistings.

Market Position and Competition

Euronext provides primary and secondary listing services to issuing companies, with the level of competition in respect of each service varying significantly. In relation to the provision of primary listing

334

services to issuers based in Euronext's home markets, Euronext does not face significant competition. Most issuing companies seek to list their shares only once, on their relevant domestic exchange. Accordingly, Belgian, Dutch, French and Portuguese companies typically obtain a primary listing on the relevant regulated national exchange operated by Euronext, and are admitted to trading either on Eurolist by Euronext, or, in the case of certain small- to medium-sized companies, Alternext. There are no rival regulated exchanges offering primary listing services in Euronext's home territories, and therefore no material competition in respect of those issuing companies seeking primary listings that are situated in Euronext's home markets, except for MEDIP, a regulated market operating in Portugal by MTS Portugal that provides a platform for the wholesale trading between specialists of Portuguese government bonds.

Euronext competes with other exchanges worldwide to provide secondary listing services to issuing companies located outside Euronext's home territories, and primary listing services to those companies that do not have access to a well-developed domestic exchange. With its presence in five European national markets, and its cross-border integrated exchange model, Euronext is the natural gateway to the Eurozone, providing issuing companies with access through a single point of entry to a broad European investor base. As such, Euronext competes primarily with those other continental European exchanges that offer access to the Eurozone capital pool.

Euronext expects that competition to provide primary and secondary services to non-European issuing companies will intensify in the future, with Euronext having launched market initiatives in several key developing markets, including China, Russia and Israel, in 2005. As Euronext continues to target issuing companies located in developing markets, it will likely compete more vigorously with exchanges globally.

Derivatives Trading

General

Euronext.liffe is Euronext's international derivative markets business, comprising derivative markets in Amsterdam, Brussels, Lisbon, London and Paris. Euronext.liffe is the second largest derivative market in Europe by volume, and the second largest in the world by average daily value of trading. During 2005 and the first half of 2006, average daily volume was 2.9 million contracts valued at almost €1.4 trillion. 606 million and 387 million contracts were traded on Euronext.liffe in 2005 and the first half of 2006, respectively. The total value of contracts traded on Euronext.liffe was €307 trillion in 2005 and €185 trillion in the first half of 2006.

The following tables set forth comparative data regarding derivatives trading on the principal exchanges during 2005:

Average Daily Volume (in € millions)		Number of Contracts Traded (in millions)

335

Through a single electronic trading platform (known as LIFFE CONNECT®), Euronext.liffe offers a wide and growing range of derivative products to customers in 31 countries. The roll-out of LIFFE CONNECT®, which was originally the trading platform of LIFFE, was effected in 2003 and 2004 across all of Euronext's derivatives markets. Through this platform, Euronext.liffe offers customers sophisticated trading in a wide range of interest-rate, equity, index, commodity and currency derivative products. Moreover, customers who might normally use the OTC market to trade equity derivatives can also now trade cheaply and efficiently using one or more of Euronext.liffe's three new wholesale services—Afirm, Bclear and Cscreen—launched in 2005, as described below.

Euronext's revenue from derivatives trading on LIFFE CONNECT® consists of fixed per-contract fees for the execution of trades of derivatives contracts (futures and options, including equity, commodity and interest-rate derivatives) on Euronext.liffe. Revenues therefore depend on the number of contracts traded on Euronext.liffe and fees charged per contract. See "Management's Discussion and Analysis of Financial Condition and Results of Operations of Euronext" for further information. In 2005, derivatives trading revenues were €331.9 million, or 34.5% of Euronext's total revenues.

Trading Platform and Market Structure

LIFFE CONNECT® is the central electronic trading platform for Euronext's derivative markets. Initially developed in 1998 with customers and selected independent software vendors to replace LIFFE's open outcry trading floor with a fully electronic market, reflecting the benefits of the trading platform, LIFFE CONNECT® is now used not only by Euronext.liffe's derivative markets in Amsterdam, Brussels, Lisbon, London and Paris, but also by other exchanges including the Chicago Board of Trade (CBOT), the Kansas City Board of Trade (KCBT), Minneapolis Grain Exchange (MGEX), Winnipeg Commodity Exchange (WCE) and Tokyo Financial Exchange (TFX).

LIFFE CONNECT® features an open system architecture. An Application Program Interface (API) allows users to build or purchase trading or view-only applications to suit their specific business needs. Traders commonly do this via one of the many front-end trading applications that have been developed by independent software vendors (ISVs). These applications are personalized trading screens that link the user to the market via a chosen network. This offers the potential to integrate front/back office trading, settlement, risk management and order routing systems.

Key features of the LIFFE CONNECT® trading platform include:

•: Capacity, performance and scalability. LIFFE CONNECT® has been designed to handle significant order flows and transaction volumes and to be scalable. Between 2003 and 2005, technology enhancements resulted in a more than five-fold expansion of the order handling capacity of the LIFFE CONNECT® system, and further enhancements took place in 2006 leading to a doubling of order handling capacity as compared to the level achieved at year-end 2005.
•: LIFFE Market In Depth. LIFFE CONNECT® disseminates the full order book to all trading clients. Users are continually notified of all active orders in the central order book, making market depth easy to monitor. Furthermore, the Euronext liquidity provider system ("ELPS") delivers full screens and tight spreads for all series, delivering deep liquidity and enabling investors to enter and exit the market easily.
•: International distribution network. LIFFE CONNECT® is available in the world's major financial centers with approximately 800 sites trading on the system in 31 countries, covering all major time zones.
•: Matching. Orders can be matched either on a price/time or pro rata basis, configurable by contract with transacted prices and the aggregate size of all bids and offers above and below the market updated on a real-time basis.

336

•: Wide range of strategies and order types. It is possible to trade a wide range of order types and strategies on LIFFE CONNECT®, providing flexibility and increased trading opportunities. LIFFE CONNECT® offers a large choice of strategy trading with implied pricing, to maximize derivatives liquidity. The range of strategy-types offered at host level includes six futures strategy types with implied in and out prices on calendar spreads, butterflies, strips, packs, bundles and condors, as well as 40 options strategies. LIFFE CONNECT® also offers 20 delta neutral strategy types. Offering this full range of strategy markets at the trading host level reduces 'legging risk' and lowers the cost of trading.

Products

Interest rate products

Euronext.liffe's core product line (in addition to equity option contracts, described below) is its portfolio of short-term interest rate contracts. Short-term interest rate contracts enable users to manage the risks associated with interest rate fluctuations in the world's major currencies, from anywhere between three months to five years into the future. Euronext.liffe's main products within this range are based on the euro and sterling interest rate. Trading volumes in Euronext.liffe's flagship product in this area, the Euribor Contract, have grown as the euro has increasingly established itself as a global reserve currency.

Equity products

Equity options enable holders to hedge against, or speculate on, changes in share prices. More than 400 European equity options (including options on shares not listed on Euronext) can be traded on Euronext.liffe, making the exchange a leading market for equity options trading worldwide. Equity options trading has historically been particularly active at Euronext Amsterdam. The successful full- screen market model, which now characterizes this equity options market, is currently being rolled out to the other Euronext.liffe centers.

Equity index products

Equity index derivatives allow holders to hedge against, or speculate on, changes in the future level of a particular index, the investor paying or receiving a cash sum representing its loss or gain on the future or option. Euronext.liffe's equity index derivatives allow customers to hedge against fluctuations in a range of European stock market indices and the European equity market as a whole.

Commodity products

Commodity derivatives allow holders to hedge against changes in the price of a number of commodities, including agricultural products such as wheat, corn, rapeseed, potatoes and soft products such as cocoa, sugar and coffee. Euronext.liffe is a leading provider of soft and agricultural commodity derivatives, and is the only exchange to offer commodities globally on an electronic trading platform. Volumes have grown strongly in recent years, as investors seek to use commodities to help diversify their portfolios.

Currency products

Currency derivatives allow investors to speculate upon, or protect themselves from, changes in the exchange rate between two currencies. Trading in currency derivatives on Euronext.liffe has declined significantly in recent years following the introduction of the euro.

OTC products

In 2005, Euronext.liffe launched three integrated services designed to provide straight-through-processing from pre-trade price discovery to post-trade registration, administration and clearing of wholesale equity derivatives trades. Together, these new services offer a flexible, secure, simple and cost-effective way of conducting wholesale equity derivatives trades. The three services include:

•: Afirm. Afirm is an "off-exchange" post-trade matching service offering affirmation or matching through to confirmation for over-the-counter (OTC) equity derivatives transactions. Afirm is designed to allow equity derivative market participants to reduce costs through the automation of manual processes and to reduce operational risk through real-time confirmation. Benefits offered by the service include automated trade confirmation, FpML messaging capability, and flat fees per trade confirmed through the service, irrespective of the size of the transaction.
•: Bclear. Bclear provides OTC equity derivative market participants a means of registering, processing and clearing wholesale equity derivatives within the secure framework of an exchange and clearing house. Through Bclear, users can register OTC business for trade confirmation, administration and clearing as an exchange contract, while retaining the flexibility to specify contract maturity, exercise price and settlement method on futures and options on over 350 European blue-chip stocks and 12 indices.
•: Cscreen. Cscreen is a dynamic application that enables brokers and traders to post and respond to "Indications of Interest" (IOI) for wholesale equity derivatives.

Trading members

Trading members in Euronext's derivative markets are either dealers or brokers. Trading members can also become liquidity providers. Liquidity providers enter into agreements with Euronext, specifying their responsibilities. Liquidity providers are able to place several series of bulk quotes in one order, allowing trading members to send buy and sell orders for many contract months using only one message. If a trading member is disconnected from the trading system, all of its quotes (except good-till-cancelled orders) will be automatically cancelled by the system through a bulk cancellation function.

Market position and competition

Euronext competes with a number of European derivatives exchanges, most notably Eurex, the derivatives platform operated by Deutsche Börse. However, Euronext primarily faces competition from the OTC trading of derivatives. The overwhelming majority of derivatives transactions are executed OTC, and the ability of customers to switch trading volumes OTC exercises a significant competitive constraint on Euronext's activities.

Information Services

General

Financial information is essential for exchange trading. Accordingly, Euronext's Information Services business unit distributes and sells market information to data vendors (such as Reuters and Bloomberg), listed companies and financial institutions and manages over 200 national and international indices. Its core activity is the distribution of real-time market data. This data includes price and transaction data, and order book data on all of the instruments traded on the cash markets and derivative markets of Euronext, as well as information about Euronext's indices. Euronext generally makes the market data linked to trading on each of Euronext's trading platforms available as close to real time as possible, a service referred to as "real-time" price information. This real-time data is subject to fees, to be paid by vendors

338

and users. In addition, delayed data, meaning data that is at least 15 minutes old, is currently provided free of charge.

Revenue from Information Services consists of fees Euronext charges to a variety of users for the use of Euronext's real-time market data services. In addition, Euronext charges data distributors license fees for the right to distribute Euronext data to third parties and service fees for their direct terminal connections. See "Management's Discussion and Analysis of Financial Condition and Results of Operations of Euronext" for further information. In 2005, Euronext generated Information Services revenues of €93.6 million, or 9.7% of Euronext's total revenues. A significant proportion of these revenues came from monthly end user fees, which are collected by data distributors based on the level of end user usage they report to Euronext.

Real-time Market Data

The distribution of real-time market data is the core activity of Information Services. This data includes price and transaction data, and order book data on all of the instruments traded on the cash markets and derivative markets of Euronext, as well as information about Euronext's indices. The data is sold in different forms, and can be packaged according to the type of instrument (shares, derivatives or indices), the depth of the information (depth of the order book, number of lines of bid and ask prices), and the type of customer (professional or private).

The data is disseminated primarily via data vendors, but also directly to financial institutions, websites and other service providers in the financial sector. The information services strategic business unit charges fees for the dissemination of data, such as an annual fee for the direct receipt of data, and license fees for the redistribution of real-time data. In addition, license holders pay a monthly fee based on the number of end users who receive data from them and the information package subscribed to; generally, these user fees are paid by end users themselves and collected by license holders. As of June 30, 2006, the information services strategic business unit had 168 license holders, and the number of Euronext real-time information packages viewed by end users amounted to approximately 201,000. Many other users receive the same market data with a delay of 15 minutes.

In 2004, Euronext introduced a new data feed platform, Euronext Market Data Solution (or EMDS), aimed at consolidating its data delivery. This real-time feed will eventually distribute all of Euronext's market data. As part of this consolidation process, Euronext began distributing information relating to the cash market and the Amsterdam derivative market on EMDS in 2005, and expanded the feed to include the remaining derivatives markets in February 2006. In addition to EMDS, data will also continue to be made available through trading application programming interfaces (APIs).

Other Data Products

In addition to the real-time market data Euronext provides as described above, Euronext provides the following additional market data services:

•: Historical market data covering all Euronext's markets. This service, called NextHistory, is aimed at professionals in the financial industry. NextHistory gives customers online access to historical market data via www.databyeuronext.com or via DVD. It offers a choice between end-of-day and intraday market data on both equities and derivatives for all of Euronext's markets, in some cases going back as far as the early 1980s.
•: Daily updates about the composition of all Euronext indices. Euronext has developed a product called the Index File Service for traders, asset managers, structured product desks, analysts, professional investors, vendors and others that rely on up-to-date index information for activities including trading, fund management, research, data dissemination and risk management. Euronext's

339

subscribers pay a fee to receive daily information on the exact composition and weighting of indices as well as precise details of changes in index levels and the closing prices of constituent shares.

•: Market snapshots. This service provides full market overviews at fixed times every trading day. Various services are available and are aimed at vendors and professionals in the financial industry. A more harmonized version of this service is scheduled to be launched before the end of 2006.
•: ListQuote. This service provides real-time stock price information to Euronext's listed companies, for publication on their own website.

Official Lists

The Information Services business unit publishes a number of daily official price lists, such as the Cote officielle in Paris, the Daily Bulletin in Lisbon and the Amsterdam Daily Official List.

Indices

Euronext creates and compiles indices based on Euronext's market segments, Euronext's product segments and other products traded on Euronext's exchanges to enhance the profiles of issuers listed and products traded on Euronext's exchanges and to increase trading revenues. Euronext also continues to produce indices that were created by Euronext's exchanges prior to Euronext's formation, particularly national indices. Euronext's indices are compiled by Euronext's exchanges and their subsidiaries and are marketed by Euronext's subsidiary, Euronext Indices B.V.

Euronext has over 200 indices, including the flagship AEX®, BEL 20®, CAC 40®, PSI 20® and Euronext 100® indices. Euronext's primary indices are set forth in the following table:

	Euronext Amsterdam	Euronext Brussels	Euronext Lisbon	Euronext Paris	Euronext wide
Blue-chip indices	AEX®	BEL 20®	PSI 20®	CAC 40® CAC Next 20®	Euronext 100 Index® NEXTCAC 70®
Mid-cap indices	AMX®	BEL Mid®		CAC Mid 100®	Next 150®
Small cap indices	AScX®	BEL Small®		CAC Small 90®
All-share indices	AAX®	BAS®	PSI Geral®	CAC ALLShares

Companynews

Euronext's Information Services business unit also distributes and sells press releases from listed companies to the market, to vendors, news agencies and financial institutions. In response to the adoption of the EU transparency directive, which is expected to be implemented in 2007, Euronext will restructure its product offering with respect to listed companies, to whom these distribution services had previously been provided free of charge. Pursuant to the transparency directive, listed companies must adhere to certain minimum requirements in disclosing price sensitive information. In order to do so, most of these companies are expected to outsource their needs to a specialized service provider. In March 2006, Euronext acquired Companynews, one such provider with a strong market position in France, to help satisfy the anticipated needs of listed companies in the European countries.

Sale of Software: GL TRADE

General

GL TRADE, a subsidiary of Euronext, is a global provider of front to back-office solutions for international financial institutions on both the buy side and the sell side. GL TRADE's software and proprietary network give GL TRADE's customers real-time access to more than 120 electronic markets

340

around the world and link participants in the international financial community. Using GL TRADE's products and services, its customers can trade shares, bonds, commodities and derivative instruments, view comprehensive financial information and automate all of their order flow from the front to the back office. GL TRADE has over 3,500 clients, including 650 major financial institutions.

GL TRADE has been listed on Eurolist by Euronext in Paris since 1999 and has been included in the Next Economy segment since the segment's launch. It had a market capitalization of approximately €325 million as of June 30, 2006. As the owner of approximately 40% of GL TRADE's shares, both directly (9.3%) and indirectly via a 55.8% shareholding in a company (Financière Montmartre) that holds 55.2% of GL TRADE's shares, Euronext is GL TRADE's major shareholder and consolidates the financial statements of GL TRADE into its own financial statements. In 2005, Euronext's revenues from GL TRADE amounted to €179.2 million, or 18.6% of Euronext's total revenues.

Products and Services

GL TRADE has developed a range of front-to-back office solutions and services to meet the needs of the financial community. GL TRADE's offering is structured around six business lines, consisting of:

•: Front Office Solutions (GL TRADE's historical core business);
•: Buy Side Trading Solutions: GL FAST;
•: Post Trade Derivatives;
•: Back Office Securities;
•: Cash and Risk Management: TRADIX; and
•: Banking Risk: Fermat.

Front Office Solutions

GL TRADE offers its clients GL STREAM™, the first straight through processing solution for multiple listed security types (equities, futures, options, commodities, forex and bonds). The system offers automated handling and real-time optimization of all processes involved in managing a market order.

GL STREAM™ covers trading and order management and market connectivity. It has been developed with an open architecture and a flexible infrastructure that can operate either on the client's site or on an ASP model. GL STREAM™ is fully compatible with third-party applications via the FIX (Financial Interface eXchange) protocol, and, for clients seeking the best possible performance, via APIs (Application Protocol Interface).

Trading and order management. Volumes traded on financial markets are constantly growing. Client needs are therefore evolving towards more powerful order management and trading solutions. In addition, the future implementation of new regulations in the U.S. (Reg. NMS) and in Europe (MiFID) will require brokers to make strategic choices in terms of best execution, order internalization and reporting. The GL STREAM™ Workstation combines client orders and market orders on a single screen (with 500,000 listed products viewable on a single screen, along with visualization of a full range of market data). A wide range of fully integrated modules facilitates the execution of complex orders.

Market connectivity. Traders can access electronic financial markets via GL GATEWAYS, which are directly connected to the central systems of markets. GL TRADE offers broad access to centers of liquidity: 120 electronic markets worldwide, including 68 equity and bond markets and 52 derivatives markets, including commodities. Continuous efforts to optimize order-processing servers have made it

341

possible to transfer an order to the market in under three milliseconds, with the ability to place 6,000 orders per second in each market.

Market data and content. GL TRADE's market information service supplies essential financial information directly to users' screens. It offers, in real time, data from specialist information providers (AFP, AFX, Dow Jones, S&P MarketScope, Trading Central, etc.) and from connected markets: real-time pricing, order books and market depth. It includes all U.S. data flows (NASDAQ, NYSE, INET, Supermontage, Archipelago) in particular.

GL NET: A dedicated network for order routing and transmission of financial data. GL NET is a dedicated international private network serving clients in the financial services industries. It enables real-time trading in all types of financial securities on 120 cash, derivative and OTC markets. Designed with an open architecture, it can be accessed not only through GL TRADE workstations by both buy siders and brokers, but also via FIX applications or third-party systems. The GL NET network links the main members of the financial community with the growing number of buy side users. The network provides its members with optimal levels of security, reliability and availability for the transmission of orders. Its large bandwidth ensures an average speed for order routing of 0.25 seconds worldwide, with no loss or distortion.

Buy Side Trading Solutions: GL FAST. GL FAST offers the buy side community the GL WINWAY workstation. This links the recognized benefits of the GL WIN platform with the features of GL XLS, an analytical module designed for clients that use Excel to manage their orders. This solution enables buy side clients to develop trading strategies and to forward their orders to several brokers. GL WINWAY provides all buy side trading functionality, such as market access and algorithmic trading. This solution is also available as an ASP offering.

Post Trade Derivatives: post-trade management for derivatives markets. Post trade solutions provide automated real-time management of the entire deal settlement process and manage the allocation and delivery of all necessary information to the back office. The acquisition of Ubitrade in December 2004 enabled GL TRADE to integrate a dedicated listed derivative market back office solution within its existing product range. GL TRADE is currently able to offer full and integrated solutions from front office to back office on listed derivatives markets. This integration has also led to the creation of a wholly ASP front to back solution, which will enable faster deployment for new members.

Back Office Securities: post-trade management for equity and bond markets. The acquisition of MSTS' back office business in late 2003, and that of Oasis in July 2005, have enabled GL TRADE to integrate sophisticated electronic back office solutions for equity and bond markets into its product offering. These provide management of settlement and delivery data flows with international custodians, calculation of provisional cash balances and associated borrowing-lending functions. Oasis has also added connection to U.S. clearing houses and settlement agents to its offering, which includes the production of information required under local laws.

Cash and risk management: TRADIX. The TRADIX business line offers French and international banks and major companies effective cash management and risk hedging solutions. Following the strong sales performance of TRADIX in 2005, particularly in France and the Middle East, GL TRADE plans to seek similar success in other regions, drawing on the strength of GL TRADE's sales networks and the synergy identified with trading and order management products.

Banking risk management: Fermat. GL TRADE is the sole distributor in Germany of Fermat banking risk management products. These help calculate regulatory solvency ratios, produce simulations and supply regulatory authorities with the information required under the Basel II rules.

342

Customers

GL TRADE sells its products and services primarily to large international financial institutions that use its solutions in connection with their brokerage activities. GL TRADE has approximately 650 clients (excluding individual GL multimedia clients). Sell side clients account for approximately 70% of the total and buy side clients for approximately 20%. Back office clients make up most of the remaining balance. Approximately 60% of GL TRADE's clients are equities specialists and 20% are derivatives specialists.

Market Position and Competition

GL TRADE's business can be split into four main competitive segments: order processing, electronic trading networks, provision of financial information to financial institutions and settlement-delivery systems. GL TRADE's order processing systems for equity markets compete with those offered by Orc Software, SunGard, Royal Blue and RTS. For derivatives markets, GL TRADE's main competitors are Patsystems, NYFIX and Trading Technologies. In electronic trading networks, GL NET faces competition from companies like Bloomberg and Reuters as well as financial institutions that develop solutions in-house. In the derivatives back office market, GL TRADE competes with the market leaders, Rolfe & Nolan and SunGard. TRADIX, which faces competition from numerous other companies, has made a strategic decision to focus on the specific niche of corporate cash management teams. On the buy side market, GL TRADE's flagship product, GL WINWAY, faces competition primarily from very large brokers and from Trading Screen. Companies such as Flextrade and Portware pose the main challenges in algorithmic trading, sometimes known as execution management systems.

MTS

Euronext currently owns 51% of an Italian joint venture entity, MBE Holding, that owns 60.37% of the voting shares of Societa per il Mercato del Titoli di Stato (which is referred to in this document as MTS), which is a leading electronic trading platform for European fixed-income securities, particularly government bonds. Borsa Italiana owns the other 49% of MBE Holding as of June 30, 2006. Euronext proportionally consolidates MBE Holding in its accounts. MTS generated total revenues of €58.3 million in 2005. Euronext consolidated MTS for one month in 2005 following its acquisition by MBE Holding, recording consolidated revenues from MTS of €1.4 million.

Overview of MTS

MTS is a regulated electronic exchange for government bonds and other types of fixed income securities. MTS is authorized to conduct these activities by Italy's Ministry of Economy and Finance and is regulated by the Bank of Italy and the Commissione Nazionale per le Società e la Borsa (CONSOB), the Italian stock market regulator. Since the adoption of the Euro in 1999, MTS has covered the national debt markets of every EU member state as well as government bond markets of other countries. The MTS market model uses a common trading platform for all domestic marketplaces, while corporate governance and market supervision are based on the respective national regulatory regimes. The MTS Group today covers over 30 marketplaces through various companies and continues to expand its geographic scope. In 2005, MTS signed a memorandum of understanding with the Shanghai Stock Exchange to cooperate in creating a domestic fixed income market in the People's Republic of China, and also signed an agreement with the State of Israel to establish MTS Israel, which will be the official electronic inter-dealer market for Israeli government bonds.

343

MTS Marketplaces

MTS and its subsidiaries operate several marketplaces offering a wide range of products, among which the most significant are:

•: MTS Italy Cash, which provides wholesale electronic markets for Italian government bonds and other types of fixed income securities;
•: EuroMTS Cash, which is the reference electronic market for EuroBenchmark bonds with a pool of instruments that includes benchmark securities from Austria, Belgium, Brazil, Bulgaria, China, Croatia, Cyprus, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Lithuania, Mexico, the Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, South Africa, Spain, Turkey and Venezuela, as well as agency and supranational bonds, inflation-linked bonds, covered bonds from Spain, France, Germany, the UK and Ireland, and benchmark treasury bills;
•: MTS Deutschland Cash, which manages the electronic trading platform for German government bonds, Länderbonds and German treasury certificates;
•: MTS Money Markets, which deals primarily in repos and European treasury bills; and
•: BondVision, which is a leading dealer-to-client ("B2C") fixed income electronic bond trading market. It was launched in 2001 in response to demand from institutional investors for access to the liquidity of the MTS Markets. While the dealers active on BondVision are largely those dealers active on the MTS B2B platforms, its clients are institutional investors, including investment managers, hedge funds, private banks and proprietary traders.

Before the acquisition of MTS, Euronext and MTS had closely cooperated for many years through two partnerships aimed at promoting bond markets and indices: MTS France and MTSNext. MTS France operates the leading electronic trading platform for French sovereign and quasi-sovereign securities. Euronext Paris and MTS each hold a 22.5% stake in MTS France, with the remainder being held by French primary dealers. MTSNext is a joint-venture between MTS and Euronext responsible for the management and promotion of the EuroMTS Indices.

Competition

Almost the entirety of fixed income securities trading takes place off-exchange. MTS' key competitors are inter-dealer brokers, such as ICAP plc and Cantor Fitzgerald & Co. (that, through eSpeed, Inc., operates the world's largest market for government bonds), which provide specialist intermediary services that facilitate fixed income securities transactions. Fixed income securities are also traded bilaterally by large financial institutions and commercial banks, and through a variety of electronic multi-lateral trading venues.

The MTS Acquisition and Related Agreements

On November 18, 2005, Borsa Italiana and Euronext acquired 51% of MTS through MBE Holding. Euronext and Borsa Italiana's respective cash contributions were €69 million and €56 million to capitalize MBE Holding, which in turn subscribed newly issued MTS shares in a share capital increase. The subscription price paid by MBE Holding was subsequently distributed as share premium reserve to compensate MTS' original shareholders. After the acquisition by MBE Holding of the 51% stake in MTS, MBE Holding purchased, via a pre-emptive rights subscription and sale mechanism, an additional 9.37% of MTS shares, bringing its current shareholding to a 60.37% stake. Primary international banks and financial institutions own the remaining 39.63% of MTS.

344

Under the terms and conditions of the acquisition agreement, each of Euronext and Borsa Italiana undertook, for a period of 10 years:

•: to maintain and develop the role of MTS as a European hub for all sovereign and governmental bonds and develop the role of MTS as a European hub for fixed-income products;
•: to maintain the headquarters of MTS in Italy and to keep MTS subject to Italian corporate and regulatory laws and regulations;
•: to preserve the MTS market as a regulated investment exchange with the highest standards of transparency; and
•: not to amend certain provisions of the bylaws of MTS without the consent of the Italian Ministry of Economy and Finance.

Further, the bylaws of MTS prohibit Euronext from undertaking, directly or indirectly, including through any company within the group of such controlling entity, any new activity in the European Union that competes with any screen-based wholesale bond markets which MTS operates, except for the wholesale market of derivative financial instruments.

MTS and MBE Holding Governance Arrangements

On October 21, 2005, Euronext and Borsa Italiana entered into a shareholders' agreement with a five-year term relating to MTS and MBE Holding. The most important ownership arrangements contained in the shareholders' agreement and the related bylaws of MTS and MBE Holding include:

•: Each of Euronext and Borsa Italiana agrees to hold MTS shares only through MBE Holding and to automatically terminate the shareholders' agreement in the event that either party ceases to hold its initial holding in MBE Holding.
•: Until November 18, 2010, Borsa Italiana has the right, at its sole discretion, to sell to Euronext (which will be obliged to purchase) all, but not less than all, of the shares then owned by Borsa Italiana in MBE Holding at a price reflecting agreed pricing terms mainly correlated to MTS' performance.
•: In the event of a change of control of either Euronext or Borsa Italiana, the other party will have the right to purchase all of the other party's shares in MBE Holding at fair market value within 90 days thereof.
•: Under the MBE Holding and MTS by-laws, in the event that either party intends to transfer MBE Holding Shares or MTS shares to a third party (other than an affiliate), the other party has a right to purchase the underlying shares on a preferential basis. As to MBE Holding shares, in the event that the non-transferring party decides not to exercise such right and the transfer results in a change of control in MBE Holding, the non-transferring party has the right to sell to the acquiring third party all or part (but not less than 15% of the share capital of MBE Holding) of its MBE Holding shares. As to MTS shares, a transferring shareholder must obtain prior approval from the Italian Ministry of Economy and Finance before executing a transfer of MTS shares that would result in a change of control of MTS.

Post-Trade Service Providers

Clearing and settlement of trades executed on the Euronext exchanges is effected by LCH.Clearnet (for central counterparty clearing) and Euroclear Group (for settlement, except for trades executed on the markets organized by Euronext Lisbon in Portugal, where it is still effected by Interbolsa, a wholly-owned subsidiary of Euronext Lisbon). LCH.Clearnet and Euroclear are independent entities that provide services to Euronext pursuant to contractual arrangements. Euronext initially owned the entities that

345

provided clearing and settlement services to its continental European exchanges, but gradually divested them to LCH.Clearnet (for the clearing entities) and Euroclear (for the settlement entities). Interbolsa, which provides settlement services to Euronext Lisbon, is the only post-trade entity currently fully-owned by Euronext. In addition to receiving clearing services from LCH.Clearnet, Euronext also has a substantial minority shareholding in and board representation on LCH.Clearnet. Euronext also has a small shareholding in and board representation on Euroclear.

Euronext's Relationship with LCH.Clearnet

The LCH.Clearnet Group was created in December 2003 as a result of the merger between Banque Centrale de Compensation S.A. (known as Clearnet) and The London Clearing House Limited (LCH). Prior to the merger, Clearnet was owned, directly and indirectly, as to 80.2% by Euronext, and 19.8% by Euroclear, and LCH was owned as to 75% by various commercial and investment banks, stockbrokers, dealers and trading companies that in each case were party to an active clearing membership agreement with LCH, and 25% by three UK-based exchanges, namely LIFFE Administration and Management (a Euronext subsidiary) (17.7%); London Metals Exchange (LME) (5.4%); and International Petroleum Exchange (now ICE Futures) (1.8%). Upon completion of the merger, LCH (now LCH.Clearnet Limited) and Clearnet (now LCH.Clearnet S.A.) became wholly-owned subsidiaries of LCH.Clearnet Group.

Euronext has a multi-faceted relationship with LCH.Clearnet, as shareholder, clearer to its exchanges and service provider.

Euronext's Relationship as Shareholder

Euronext currently holds, through its subsidiaries, a number of shares in LCH.Clearnet representing 24.9% of LCH.Clearnet's fully diluted share capital, and redeemable convertible preference shares (or RCPS), which are voted by an independent third party and which on conversion or sale will convert into ordinary shares representing 16.6% of LCH.Clearnet's fully diluted share capital. Euronext is entitled to appoint two board representatives for so long as it holds shares representing 15% or more of LCH.Clearnet's fully diluted share capital, and one representative for so long as it holds between 5% and 15% of LCH.Clearnet's fully diluted share capital. In addition, Euronext is entitled to appoint two board representatives for so long as it holds RCPS representing in excess of 6.6% of LCH.Clearnet's fully diluted share capital, but such entitlement decreases to one board representative once Euronext holds RCPS representing less than that amount.

Currently, Euronext has appointed Jean-Francois Théodore, Olivier Lefebvre, Clara Furse (the Chief Executive of the London Stock Exchange) and Dominique Hoenn to the board of LCH.Clearnet pursuant to these rights.

LCH.Clearnet shares may only be held by three categories of shareholders: users, exchanges or Euroclear, and each member is subject to a specified maximum number of voting rights that may be exercised at a general meeting. Where shares are to be transferred, pre-emption rights will operate to provide either users or exchanges with a right of first refusal over the shares, thus maintaining, at the shareholders' option, the initial balance between shareholder categories, but there may be no transfer to any person (other than Euroclear) not party to a clearing agreement as user or exchange. The restrictions on share ownership and transfer are in effect until at least December 22, 2008 and may be extended by the board with shareholder approval.

LCH.Clearnet and Euronext have been involved in recent discussions regarding the potential redemption of RCPS prior to their scheduled redemption date. In that context, Euronext has entered into an agreement with LCH.Clearnet dated April 26, 2006 pursuant to which Euronext has agreed to vote its shares in LCH.Clearnet in order to support a proposal by which LCH.Clearnet would redeem the outstanding RCPS at par (i.e., €10 per share) plus accrued but unpaid RCPS dividends as at the date of redemption out of the proceeds of a public offering of securities by a member of the LCH.Clearnet group.

346

Upon redemption of the RCPS, Euronext would cease to be entitled to appoint board representatives by virtue of its holding of RCPS, but this would not affect Euronext's right to appoint 2 directors by virtue of its ordinary share holding. Implementation of the proposal is subject, among other things, to the successful completion of the securities offering and the approval by the appropriate majorities of the shareholders of LCH.Clearnet and the English High Court. Subject to the foregoing, Euronext understands that LCH.Clearnet currently anticipates that the redemption of the RCPS will take place prior to March 31, 2007.

Euronext's Relationship as Exchange

The LCH.Clearnet Group clears trades executed on the markets organized by Euronext Amsterdam, Euronext Brussels, Euronext Lisbon, Euronext Paris and LIFFE. The Euronext group remains the most significant group of exchanges to which the LCH.Clearnet Group provides clearing services.

Euronext Amsterdam, Euronext Brussels, Euronext Lisbon and Euronext Paris are parties to an amended and restated clearing agreement with LCH.Clearnet S.A. and LCH.Clearnet Group, pursuant to which such Euronext exchanges designate LCH.Clearnet S.A. as their central counterparty clearing house to provide clearing services for transactions executed on those exchanges. The agreement has a 30-month initial term (it was entered into in October 2003) and a 30-month termination notice provision.

LIFFE is party to a clearing agreement with LCH.Clearnet Limited, originally entered into on June 7, 1988 and amended and restated on July 16, 1996, pursuant to which LCH.Clearnet Limited is appointed as the designated clearing house.

Euronext as Administrative Service Provider

Under the terms of a transitional services agreement entered into in connection with the merger between LCH and Clearnet, Euronext agreed to provide on a transitional basis certain administrative services to LCH.Clearnet that, prior to the merger, had been provided to Clearnet by or on behalf of Euronext. LCH.Clearnet's reliance on the provision of such transitional services has been decreasing over time and the obligation of Euronext to provide such transitional services under the terms of the agreement is due to expire on December 22, 2006, unless extended by mutual agreement.

Euronext's Relationship with Euroclear

Euroclear is a partner of Euronext for the settlement of transactions concluded on its markets pursuant to contractual arrangements in place.

The Euroclear system was created in 1968 to hold securities for its participants and to settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment. The Euroclear system provides various other services, including securities lending and borrowing and collateral management. In addition to its role as the leading International Central Securities Depositary (ICSD), Euroclear also acts as the Central Securities Depository (CSD) for Dutch, French, Irish, Belgian and UK securities.

Euroclear Group currently settles transactions conducted on each of Euronext's markets, except for Euronext Lisbon. Euronext formerly had a substantial minority stake in the French CSD (Sicovam SA) and was formerly the owner of the CSDs in the Netherlands (Necigef) and Belgium (CIK), but divested them to Euroclear in 2001, 2002 and 2006, respectively, and they now operate as Euroclear France, Euroclear Netherlands and Euroclear Belgium, respectively.

Euronext has a direct shareholding of 2.75% in Euroclear plc, together with an indirect shareholding through Sicovam Holding (Euronext holds 9.6% of Sicovam Holding, which holds 13.1% of Euroclear plc). Jean-Francois Théodore currently represents Euronext on the Supervisory Board of Euroclear plc.

Interbolsa

Interbolsa is the Portugal-based CSD that settles trades conducted on Euronext's market in Lisbon. Interbolsa is a wholly-owned Euronext Lisbon subsidiary. Euronext has been in regular contact with Euroclear to discuss developments in the area of European consolidation its impact on the Portuguese securities market and intends to divest its interests in Interbolsa. In 2005, Interbolsa generated revenues of €15.1 million. See "Management's Discussion and Analysis of Financial Condition and Results of Operations of Euronext" for further information.

Atos Euronext Market Solutions

Background

Euronext outsources the information technology requirements of its business such as development, maintenance of information technology applications, and use of resources and software to Atos Euronext Market Solutions S.A.S. ("AEMS"), an entity 50% owned by Euronext and 50% owned by Atos Origin. The AEMS outsourcing arrangements provide Euronext with several substantial benefits in its day-to-day business, as well as generating additional revenue for Euronext. By working with Atos Origin, an information management services and information technology company, Euronext gains access to international technology skills and resources at reduced cost. The nature of the arrangements ensure that Euronext continues to receive high levels of service for its information technology needs from employees of AEMS who are already familiar with Euronext's systems. Euronext also benefits, through its equity investment in AEMS, from third-party revenues generated by AEMS, which licenses software and provides information technology services to third-party customers around the world.

AEMS grew out of Euronext's prior outsourcing 50/50 entity with Atos Origin, called AtosEuronext S.A. (AtosEuronext). The AtosEuronext entity was created in 2000 through the contribution of assets, people and technology. Euronext's contribution to AtosEuronext included the intellectual property rights for its NSC trading system, originally developed by Euronext Paris. AtosEuronext became responsible for developing, maintaining, and marketing the majority of Euronext's software products for its exchange activities.

On July 22, 2005, Euronext formed AEMS as a continuation and expansion of Atos Euronext. The main assets Euronext contributed were the activities of LIFFE Market Solutions, the information technology division of its derivatives trading business Euronext.liffe (including the proprietary LIFFE CONNECT® electronic trading system developed by LIFFE), and its 50% stake in Atos Euronext. Atos Origin contributed its own 50% share in AtosEuronext, plus other major assets from market-related businesses, including middle and back-office solutions, and its 51% stake in the connectivity platform Bourse Connect.

AEMS Business Overview

AEMS is the world's largest provider of information technology solutions for exchanges, clearing houses, banks and intermediaries. AEMS has approximately 1,200 employees, mainly in Paris and London, and has customer sites in 16 countries, and operates data centers in London, Chicago and Paris. AEMS provides hosting and technical operations for each of Euronext's five markets and Euronext is AEMS' largest customer.

AEMS provides solutions for the entire range of activities of the exchange business, from exchange trading and trade support to post-trade activities. AEMS provides Euronext and other exchanges with trade services such as the capture, booking, routing, and matching of trading orders, and links to exchanges. Its trade support services, primarily to banks and brokers, include deal capture and trade administration, trade confirmation, position monitoring, risk control, portfolio management, and back-office services. Finally, AEMS provides post-trade services to clearing houses, banks, and brokers,

348

including clearing and settlement-related services, interface to clearing and depositary services and clearing houses, custodial services, depository management, credit control and collateral management, and general ledger services.

Some of the major systems and platforms that are now owned or licensed to AEMS, and are provided or licensed by AEMS to Euronext, and in some cases to third-party customers in the financial industry, are:

•: NSC (nouveau système de cotation): A cash trading system for equity securities, bonds and other products, currently used by 15 exchanges globally (including Euronext's four cash markets).
•: LIFFE CONNECT®: An electronic trading platform for futures and options used by major derivatives exchanges worldwide.
•: Clearing 21®: A global clearing services solution for equities, bonds, futures and options used by clearing houses.
•: PAM: A market-access workstation used by traders to view market information and send and manage financial exchange orders.
•: ARAMIS: A real-time financial market supervision tool used by market regulators and supervision teams to ensure market integrity.
•: SARA: An international (G30) standards-compliant solution for clearing, settlement and depository.
•: TRS-CPS: A combined post-trade management and clearing solution used by Euronext.liffe's London derivatives market, ICE Futures and LCH.Clearnet.

In addition to the services provided to the exchange industry, AEMS offers interbanking solutions through platforms such as the Cristal platform, which manages the flow of cash between banking institutions and the French Central Interbank Settlement System. AEMS also provides solutions for the securities industry based on the Titan and Investiciel platforms.

AEMS Business Units

AEMS is organized into three business units: Exchange; Clearing & Settlement; and Capital Markets.

Exchange Business Unit

The Exchange Business Unit provides a broad range of information technology solutions and products for Euronext's cash and derivatives exchanges as well as for a number of other leading exchanges including, on the derivatives side, the Chicago Board of Trade (CBOT) and the Tokyo Financial Exchange (TFX) and, on the cash side, 15 cash markets. The services offered include end-to-end solutions linking exchanges to trading institutions and post-trading settlement, delivery and payment.

One of the most important products offered by the Exchange Business Unit is LIFFE CONNECT®, which is used by Euronext.liffe's five derivative markets, as well as by third-party customers such as CBOT, the Kansas City Board of Trade, Minneapolis Grain Exchange, Winnipeg Commodity Exchange and the TFX.

NSC (nouveau système de cotation) is another important system operated by the Exchange Business Unit, and is now used by 15 exchanges on four continents and handles the largest amount of cash trading globally by turnover. The average daily value of turnover on NSC is over €9.4 billion, and in addition 2.6 million derivative contracts are exchanged daily on markets using NSC.

349

Clearing & Settlement Business Unit

The Clearing & Settlement Business Unit provides and manages technology for the post-trade industry. AEMS provides customized platforms to manage clearing and settlement for cash and derivatives markets. Its principal customer is LCH.Clearnet. In addition, AEMS runs the entire portfolio of technology services for the Belgium Central Depository for Securities, is a full member of the Euroclear Group and also provides trade processing services for Euronext.liffe and ICE Futures.

AEMS also operates Clearing 21® for LCH.Clearnet. Initially developed by the Chicago Mercantile Exchange (CME) and the New York Mercantile Exchange (NYMEX) to harmonize clearing procedures in the U.S. futures industry, Clearing 21® is the only existing system that enables clearing houses to clear cash and derivative products on a single technical platform, in real-time and with a central guarantee. With the consent of NYMEX, CME granted to Euronext Paris a license to use the Clearing 21® system, which also allowed Euronext Paris to sublicense the Clearing 21® system to LCH.Clearnet. LCH.Clearnet therefore holds a non-exclusive and non-transferable sublicense to use and modify the Clearing 21® system.

Capital Markets Business Unit

The Capital Markets Business Unit works with banks and intermediaries to provide information technology solutions from trading through to settlement, and currently has over 1,000 banks, brokers, and trading firms on its global distribution network. AEMS currently processes 80% of "large" payments and 50% of "small" payments in the French market. More than 150 investment firms are directly or indirectly processed on its applications, including 20% of Euronext's orders and 30% of Euroclear flows.

Euronext's Contractual Arrangements with AEMS

AEMS provides IT services to Euronext pursuant to a tripartite overarching services agreement (the "umbrella service agreement"), dated July 2005, between itself, Euronext and Atos Origin entered into at the time of the formation of AEMS. This agreement put in place a framework under which the existing contracts governing the provision of services to the Euronext group by AtosEuronext were brought together with new services to be provided by AEMS, and the overall terms were harmonized. AEMS is responsible for overseeing the provision of services by itself and its affiliates under these contracts, and the agreement puts in place a mechanism for the negotiation of a combined master outsourcing agreement going forward.

Under the umbrella services agreement, the IT Facilities Management Agreement dated October 2004 and the Office Automation Agreement dated January 2005, each between Euronext and AtosEuronext, were extended (except as modified by the umbrella services agreement) to run for a period of up to forty-two months from the establishment of the entity, to enable a new master agreement to be negotiated. At the same time a fourth interim contract governing the provision of the derivatives platform services, including LIFFE CONNECT®, was put in place between AEMS and Euronext. Finally, a new Network Services Agreement was entered into in May 2005.

The umbrella services agreement also provides for a reduction of fees under the interim contracts going forward, in line with agreed targets, as well as certain commitments by AEMS to invest in the provision of services. In line with the strategic rationale behind the outsourcing, intellectual property generated by AEMS in providing Euronext with IT services is prima facie owned by AEMS, unless Euronext specifically requests a certain development which Euronext funds. However, the Umbrella Services Agreement provides that in the event of a handover of the IT services to a third-party supplier, the Euronext group retains the ability to demand a license to use certain key information technology systems going forward on market terms.

Legal Structure

AEMS is a limited liability company (société par actions simplifiée) incorporated under the laws of France. Atos Origin and Euronext each own (either directly or indirectly) 50% of the issued shares of AEMS. The financial results of AEMS are fully consolidated into the annual accounts of Atos Origin. AEMS is recorded in Euronext's accounts as an equity investment.

AEMS has a dual-board structure, with a managing board responsible for the day-to-day running of AEMS and an overseeing supervisory board. At current shareholding levels, Atos Origin has the right to appoint five supervisory board directors, and Euronext has the right to appoint four. The nomination and appointment of the chairman of the supervisory board is made by the supervisory board, acting by a qualified (two-thirds) majority. The chairman is appointed from the members of the supervisory board. The managing board is composed of up to five members, who are appointed and removed by the supervisory board.

AEMS has a Strategic and Investment Committee, a Remuneration Committee and an Audit Committee that report to the supervisory board. For so long as Euronext holds one-third of the shares, each of these committees will comprise three Euronext directors and two Atos Origin directors, except that the Audit Committee comprises two Euronext directors and two Atos Origin directors.

Each of Atos Origin and Euronext pursuant to a shareholders' agreement with respect to AEMS has veto rights over specified corporate actions for so long as it holds at least one-third of AEMS' shares. Euronext has additional specified veto rights for so long as its shareholding remains above such level. The shareholders agreement also provides for specific circumstances (including events relating to change in control or service quality levels) in which Euronext will have the right to require Atos Origin to sell Euronext a specified percentage of Atos Origin's AEMS shares at specified discounts to the valuation price, including as a consequence of repeated breaches of critical service levels that give rise to a termination event under the agreement described above.

Powernext

Euronext holds a 34% stake in Powernext, a multilateral trading facility in charge of managing an organized power exchange, which has become a leading benchmark for energy prices in France and throughout Europe. In 2005, Powernext generated revenues of €7.5 million. Powernext was launched in November 2001 following the liberalization of Europe's electricity markets under a 1996 European Directive, which was implemented under French law in 2000. On this market, electricity producers, consumers and traders can trade power for delivery on the French electricity network. Since its creation, Powernext has benefited fully from France's leading position in Europe's electricity market and network.

Powernext aims at (i) creating a benchmark reference price in Europe, through a dedicated platform and an increase in the diversity of market participants, and by benefiting from the privileged position of the French electricity hub, and (ii) playing a decisive part in European electricity markets' rationalization.

Powernext has three trading markets:

•: Powernext Day-Ahead™, a market launched in order to create a short time reference price on the French electricity market and to provide participants with the means necessary to effect a day-ahead balance of their portfolio;
•: Powernext Futures™, a market that allows members to use derivatives contracts for hedging, arbitrage or risk management purposes. Powernext Futures™ constitutes a medium-term price reference in the electricity market; and
•: Powernext Carbon, a new spot market for carbon dioxide emissions trading.

351

Contracts for 19.7 terra watt hours (TWh) were traded on the Powernext Day-Ahead™ electricity spot segment and contracts for 62.4 TWh were traded on the Powernext Futures™ market in 2005. In addition, Powernext introduced a new market for its users in 2005: Powernext Carbon, Europe's spot market for carbon dioxide emissions trading.

Powernext also provides weather indices in partnership with Meteo France that are designed for use in weather derivatives and other weather-related applications.

Insurance

Euronext maintains a comprehensive insurance program, which is intended to cover its commercial and operational risks. All of its main insurance policies are consolidated at the group level in order to ensure consistency of coverage across the group and to reduce premiums through economies of scale.

Euronext's insurance policies generally fall into three categories:

•: financial policies, which cover directors' and officers' liability, professional indemnity and criminal acts;
•: general policies, which cover property, theft, equipment damage, business interruption, civil and product liability; and
•: local policies, which cover employer responsibility with respect to workers' compensation, travel, motor vehicles, etc.

The scope of risks covered pursuant to these insurance policies is determined by reference to Euronext's activities, while coverage limits are based on Euronext's total assets and revenues. Euronext's insurance brokers advise the group on insurance-related matters, and all underwriters are analyzed from a credit rating perspective. Euronext has also developed risk management procedures and business continuity plans to complement its insurance coverage.

Legal Proceedings

Euronext is involved from time to time in various legal proceedings in the ordinary course of business. Euronext does not believe that any of the legal proceedings in which Euronext is currently involved will have a material adverse effect on Euronext's results of operations, liquidity or financial condition.

Via Net.Works Inc.

Following the IPO of Via Net.Works Inc. on the Euronext Amsterdam market and Nasdaq on February 11, 2000, the Euronext Amsterdam market was criticized by the media for allowing trading in shares of Via Net.Works Inc. to start before trading started on Nasdaq. Prior to the start of trading of these shares on Nasdaq, trading on the Euronext Amsterdam market opened and closed at a price of €89 per share. After the close of trading on the Amsterdam market, trading on the Nasdaq opened at a price of $41 per share. At the start of the next trading day, Via Net.Works Inc. share price on the Amsterdam market dropped to €50 per share. The STE (the predecessor of the AFM) conducted an inquiry into the listing of Via Net.Works. In 2002, the AFM notified Euronext Amsterdam that it had decided not to fine or sanction the company in connection with this IPO. This decision is final.

Following the IPO, legal proceedings were instituted against the Amsterdam Exchanges N.V., the predecessor of Euronext Amsterdam, by a private investor and the Via Net.Works Foundation, claiming to represent approximately 600 investors and currently claiming compensation in respect of trading losses of approximately €11 million. Euronext Amsterdam is strongly defending itself against these claims. The private investor claim (€250,000) and Foundation claim were both dismissed by the District Court of Amsterdam. Appeals were filed by the parties with the Amsterdam Court of Appeals and judgment is pending in both cases.

NCP

To date, 48 dealers on the French Derivative Markets (NCPs) have filed similar claims on several dates against Euronext Paris before the Paris Commercial Court, claiming damages due to the malfunction of the IT platform for derivatives trading at the time of the migration from floor to screen trading, and also to the development of automated price injection models, which strongly reduced their own trading activity.

353

Damages claimed to date total €73.8 million. Since the basis of the claim and its legal grounds were considered unclear, no provision was recorded as of December 31, 2005 or as of June 30, 2006.

Trading Technologies

Euronext's subsidiary, GL TRADE, is involved in a litigation initiated by Trading Technologies (TT) in the U.S., which also concerns other companies in the same industry as GL TRADE. TT alleges infringement of its patents relating to trading screen technology. TT has not yet specified the amount of damages it is seeking. Since it pre-existed TT by many years, GL TRADE believes that it has a strong "prior art" defense and therefore did not record a provision in respect of this litigation as of December 31, 2005 or as of June 30, 2006.

Major Shareholders and Affiliates

The following table sets forth information concerning persons Euronext knows or understands based on public filings to be beneficial owners of more than five percent of Euronext's common shares as of August 31, 2006.

(1): In January 2002, Euronext Group acquired all the outstanding shares of LIFFE (Holdings) plc. The total consideration paid amounted to € 926 million, including the cash settlement of outstanding options and warrants and including acquisition costs. Total goodwill in relation to the acquisition amounted to €647 million. In addition to own funds used for an amount of €476 million, the transaction was financed by a credit facility of GBP 250 million (€409 million), and the issuance of Variable Rate Guaranteed Unsecured Loan Notes for an amount of €27 million. The remainder of the loan facility (GBP 150 million) was redeemed in February 2004 with the proceeds of a GBP 250 million fixed-rate bond loan issued also in February 2004. At the same time the fixed rate was swapped to floating rate by means of an interest rate swap. The assets, liabilities, results and cash flows of LIFFE have been included in the consolidated accounts of Euronext as from January 1, 2002.
(2): In January 2002, the Group acquired 100% of the shares of Bolsa de Valores de Lisboa e Porto (BVLP). The total consideration paid, based on the Euronext share price at the time of the acquisition and including acquisition costs, amounted to €138 million. The consideration was paid partly in cash (€35 million) and partly in newly issued Euronext N.V. shares (4.8 million shares). The

358

assets, liabilities, results and cash flows of BVLP have been included in the consolidated accounts of Euronext as from January 1, 2002.

(3): In June 2003 the Group reached an agreement with the London Clearing House (LCH) to merge BCC/Clearnet and LCH into a new independent UK holding company LCH.Clearnet Group Ltd. On December 22, 2003 the Group exchanged its 80% stake in BCC/Clearnet and its 17.7% interest in LCH for 49.1% of LCH.Clearnet Group.Simultaneously, Euronext sold 7.6% of these shares to third parties. The Group's 41.5% interest in LCH.Clearnet Group is divided into ordinary shares (24.9%) and Redeemable Convertible Preference Shares (16.6%). Euronext recorded a gain on disposal of discontinued operation of €175 million in connection with the transaction. As from December 22, 2003, Euronext no longer records clearing revenues, but instead accounts for its interest in LCH.Clearnet under the equity method, recording its share of income under "Income from associates."
(4): On July 22, 2005, Euronext formed Atos Euronext Market Solutions as a continuation and expansion of its pre-existing Atos Euronext relationship with Atos Origin. The main assets Euronext contributed were the activities of LIFFE Market Solutions, the information technology division of its derivatives trading business Euronext.liffe, and its 50% stake in Atos Euronext. Atos Origin contributed its own 50% share in Atos Euronext, plus other major assets from market-related businesses, including middle- and back-office solutions, and its 51% stake in the connectivity platform Bourse Connect. The transfer of the activities of LIFFE Market Solutions to AEMS led to a significant reduction in Euronext's salaries and employee benefit costs, consultancy expenses, other office, telecom and consultancy costs and depreciation charges, and a parallel increase in IT expenses, which from the date of creation of AEMS include all IT expenses related to Euronext.liffe.
(5): In January 2006, Euronext completed the sale of the Belgian central securities depository CIK N.V./SA, a wholly-owned subsidiary of Euronext Brussels, to Euroclear. In exchange for this asset, Euronext received an additional 0.4% stake in Euroclear.
(6): As from January 1, 2005, the Group no longer amortizes goodwill relating to acquisitions made before March 31, 2004 as part of a business combination, in line with IFRS 3.
(7): Dividends declared with respect to 2005 consist of a €1 per share ordinary dividend. In addition, a €3 per share capital reduction was made.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF EURONEXT

The following discussion and analysis should be read in conjunction with Euronext's audited consolidated financial statements as of and for the years ended December 31, 2005, 2004 and 2003 and with Euronext's unaudited interim condensed consolidated financial statements as of and for the six-month periods ended June 30, 2006 and 2005 included herein. Euronext's consolidated financial statements have been prepared in accordance with IFRS as adopted by the European Union. IFRS differ in certain material respects from generally accepted accounting principles in the United States of America. For a discussion of certain material differences between IFRS and generally accepted accounting principles in the United States, see "Summary of Material Differences Between IFRS and U.S. GAAP" below and the related notes in Euronext's consolidated financial statements.

Overview

Since it was founded in 2000, Euronext has been committed to promoting the integration and consolidation of Europe's capital markets and increasing the efficiency of cross-border trading. In pursuit of that objective, Euronext has pursued opportunities to consolidate and integrate its markets, most notably through the adoption of a harmonized rulebook and the integration of the Group's trading platforms through a four-year migration plan that was completed in 2004. These efforts, combined with Euronext's efforts to streamline its organizational structure to create a cross-border, business-oriented organization based on strategic business units, have allowed Euronext to reduce operating costs and to eliminate redundancies.

As a result of Euronext's continued efforts to cut operating costs and increase its revenues, despite an increasingly competitive market and sometimes turbulent market conditions, net income increased from €149.7 million in 2004 to €241.8 million in 2005. In 2003, Euronext's net income amounted to €211.8 million, but reflected in large part the one-off capital gain it recorded on its sale of BCC/Clearnet. Aside from this one-off gain, the changes in net income during the period under review primarily reflected changes in profit from operations, which amounted to €208.9 million in 2003, €200.2 million in 2004 and €318.5 million in 2005. Over the three-year period, Euronext's profit from operations increased as a percentage of revenues from 21.1% in 2003 to 22.6% in 2004 to 33.1% in 2005.

Net income and profit from operations continued to increase in the first half of 2006. High trading activity combined with strict cost control produced a 57.3% increase in profit from operations, from €140.1 million in the first half of 2005 to €220.3 million in the first half of 2006. As a percentage of revenues, profit from operations increased from 30.4% in the first half of 2005 to 39.5% in the first half of 2006.

Sources of Revenue and Principal Expense Items

Operating revenues

Cash trading

Euronext generates cash trading revenue from fees charged primarily for the execution of trades of equity and debt securities and other cash instruments on Euronext's cash market, which is comprised of the separate cash markets operated in Amsterdam, Brussels, Paris and Lisbon. For historical reasons relating to Euronext's prior ownership of Clearnet, part of the trading fee consists of a commission paid by LCH.Clearnet to Euronext as a retrocession. These payments were recorded by Euronext as part of its cash trading revenues in 2005 and 2004. In 2003, these payments were recorded as clearing revenues since Clearnet was consolidated in Euronext's accounts until the end of 2003.

360

Euronext has implemented a harmonized fee structure for its cash trading activity, which was most recently updated in February 2005. Under the current fee structure:

•: For trading in equities, there are three different fee packages. The first package involves a flat fee per trade and no minimum activity charge. The other two packages involve a monthly minimum activity charge and a fee per trade calculated on a sliding scale based on volume and the level of the minimum activity charge. An ad-valorem fee based on transaction size is also applied to each trade. No order fee is charged so long as the order/trade ratio does not exceed a specified level.
•: For trackers and investment funds, a flat fee is charged for each order placed, and an ad-valorem fee based on transaction size is applied to each trade.
•: For warrants and certificates, a flat fee is charged for each order placed, and a flat fee per trade is charged.
•: For bonds, no order fee is charged as long as the order/trade ratio does not exceed a specified level, and a fee per trade is charged according to a sliding scale based on volume.

The retrocession for cash trading activity from LCH.Clearnet is based, in the case of Euronext Paris, on a fixed amount per trade from each side of the transaction plus a variable amount that is based on a percentage of the value of the trades cleared. The retrocession for each of Euronext Amsterdam, Brussels and Lisbon is based on a flat percentage (which varies by exchange) of clearing fees collected by LCH.Clearnet in respect of trades on such exchange's cash market. The fee amounts are determined under the clearing agreement between LCH.Clearnet and Euronext's continental European exchanges, and increased on an annual basis during the 2004-2006 period. For more information concerning the relationship between Euronext and LCH.Clearnet, see "Information About Euronext—Post-Trade Service Providers—Euronext's Relationship with LCH.Clearnet."

Revenue from cash trading in any given period depends primarily on the number of trades executed on Euronext and the average price per trade charged for their execution. The level of trading activity is heavily influenced by general market conditions. Other factors may include the number and financial health of companies listed on Euronext's cash markets, and general competitive conditions.

Listing fees

Listing fees comprise admission fees paid by issuers to list securities on the cash market, annual fees paid by companies whose financial instruments are listed on the cash market, and corporate activity and other fees, consisting primarily of fees charged by Euronext Paris for centralizing shares in IPOs and tender offers. Revenues from listing fees primarily relate to shares.

Euronext has adopted a common set of listing fees for Euronext Paris, Euronext Amsterdam and Euronext Brussels. Under the harmonized fee book, domestic issuers (i.e., those from France, the Netherlands and Belgium) pay admission fees based on market capitalization to list their securities (in Portugal, the admission fee is based on the product of the number of shares to be listed and the nominal value per share), as well as annual fees based on the number of shares listed (in Portugal, the annual fee is based on the product of the number of shares listed and the nominal value per share). Subsequent listings of securities receive a 50% discount on admission fees. Non-domestic companies are charged admission and annual fees on a similar basis but are subject to lower maximum admission fees and annual fees. Euronext Paris also charges centralization fees for collecting and allocating retail investor orders in IPOs and tender offers. Listing fees are recognized upfront except for annual fees, which are recognized ratably throughout the year.

The revenue Euronext derives from listing fees is primarily dependent on the number and size of new company listings and tender offers. The number and size of new company listings and tender offers in any period depends primarily on factors outside of Euronext's control, including general economic conditions

361

in Europe and in France, the Netherlands, Belgium and Portugal (in particular, stock market conditions) and the success of competing stock exchanges in attracting and retaining listed companies.

Derivatives trading

Revenue from derivatives trading consists of fixed per-contract fees for the execution of trades of derivatives contracts on Euronext's derivatives markets in Paris, London, Amsterdam, Brussels and Lisbon. Revenues are driven by the number of trades and fees charged per contract. The principal types of contracts traded are equity and index products and short-term interest rate products, which contributed 33% and 59%, respectively, of trading revenues in 2005. Trading in equity products is primarily driven by price volatility on equity markets and indices and trading in short-term interest rate products is primarily driven by volatility resulting from uncertainty over the direction of short-term interest rates. The level of trading activity is largely outside of Euronext's control.

Euronext has recorded retrocession fees from LCH.Clearnet in respect of trades executed on Euronext's continental derivatives markets under derivatives trading revenues in 2005 and 2004. In 2003, these payments were recorded as clearing revenues since Clearnet was consolidated in Euronext's accounts until the end of 2003. The retrocession for derivatives trading activity from LCH.Clearnet is based, in the case of Euronext Paris, on a fixed amount per transaction from each side of the transaction plus a variable amount that is based on a percentage of the value of the trades cleared. The retrocession for each of Euronext Brussels and Euronext Lisbon is based on a flat percentage (which varies by exchange) of clearing fees collected by LCH.Clearnet in respect of trades on such exchange's derivative market. No retrocession fee is paid with respect to trading on Euronext Amsterdam's derivatives market.

Euronext.liffe's fee grid varies by type of contract and by type of member. With respect to the various contracts available through Euronext.liffe, fees are charged as follows:

•: Individual equity options: a flat fee per lot is charged in all Euronext.liffe business centers, except in Paris (where fees are dependent on order size) and in Amsterdam (where the fees are capped).
•: Individual equity futures: this type of contract is available in Lisbon and London, in respect of which a flat fee is charged per lot.
•: Index products: fees for these products in Amsterdam and Brussels are based on a flat fee per contract depending on premium size, and are capped in Amsterdam above a certain level. Fees in Paris are based on a flat fee per contract with a maximum of 1% of the traded amount. Fees in London and Lisbon are based on a flat fee per lot.
•: BClear: this is one of three services for wholesale equity derivatives that Euronext launched in 2005. The fee structure is based on a per lot fee per side up to a fee cap.
•: Interest rate products: these products are available in London, in respect of which a fee is charged per lot.
•: Commodity products: these products are available in London and Paris, in respect of which a flat fee is charged per lot.

Each Euronext.liffe center, except for Lisbon, provides preferred rates to market makers as follows:

•: In London, with respect to single equity options, market makers may be categorized as primary market makers (PMM) or designated market makers (DMM), which are exempt from transaction charges or receive fee discounts on business they transact in a market making capacity. A separate DMM category exists for the FTSE 100 Index options contract (ESX) as well as a specific regime that governs trades in the FTSEurofirst contract.
•: In Amsterdam, market makers pay a liquidity provider fee (€0.10 per lot) based on the category, or Euronext Class Combination (ECC), in which a market maker falls.

362

•: In Paris, market makers pay either €0.30 or €0.40 per lot for orders of up to 6,000 lots, depending on whether they act as a permanent market maker (PMM) or responding market maker (RMM). For orders above 6,000 lots, PMMs or RMMs pay €80 per trade.
•: In Brussels, market makers are eligible for a low fee, equivalent to the liquidity provider fee in Amsterdam on equity options.

MTS fixed income

In November 2005, Euronext acquired 51.0% of a joint venture entity, MBE Holding, which currently owns 60.37% of the voting shares of MTS. Euronext proportionally consolidated MTS for only one month in 2005, recording proportionally consolidated revenues from MTS of €1.4 million.

Revenues from MTS are derived from membership fees, transactions fee and post trading fees for the execution of trades of cash and money market products. MTS implemented a new fee structure in January 2005 with the following principal characteristics:

•: For the trading of cash products on its main markets (MTS Italy, EuroMTS and MTS Deutschland), MTS charges a per trade fee calculated on a sliding scale based on annual volume. Under the new fee structure, membership fees for market makers are waived.
•: For the trading of money market products, MTS charges a per-trade fee calculated on a sliding scale based on annual volume.
•: For trading on BondVision, MTS charges a fee per trade calculated on a sliding scale based on annual volume.
•: Post-trading fees are calculated on the number of settlement messages.

Revenue from MTS in any given period depends primarily on the number of trades executed on its platform and the average price per trade charged for their execution. The level of trading activity is heavily influenced by general market conditions (volatility levels in the bond markets and interest rate levels) and thus outside of Euronext's control.

Settlement and custody

Revenue from settlement and custody currently consists of fees for settling securities trades and fees for associated custodial services relating to securities traded in Euronext's cash markets in Lisbon, which are generated by Interbolsa. During each of the three fiscal years ended December 31, 2005, these fees also included settlement and custody fees generated by Euronext's cash markets in Brussels, which were generated by CIK (Belgium) which was sold to Euroclear in 2006. Settlement and custody fees vary by market, and are charged on a per-trade basis for settlement fees and on a fee based on the market value of the securities in question for custody services.

Information services

Revenue from information services consists of fees that Euronext charges to a variety of users, primarily the end-users, for the use of Euronext's real-time market data services. Euronext also collects annual license fees from vendors for the right to distribute Euronext data to third parties and a service fee from vendors for direct connection. A substantial majority of Euronext's data revenues is derived from monthly end-user fees. Euronext also derives revenues from selling historical and reference data about securities, and by publishing the daily official lists for the Euronext markets. The principal drivers of information services revenues are the number of end-users and the prices for data packages.

363

Sale of software

Revenue from sale of software primarily consists of license fees received from securities exchanges and other financial institutions for software that Euronext develops internally or licenses. Throughout the periods under review, this revenue was generated primarily by GL TRADE. In addition, until June 30, 2005, sale of software included fees received by LIFFE Market Solutions for its LIFFE CONNECT® software package. On July 1, 2005, these latter activities were transferred to Atos Euronext Market Solutions ("AEMS").

GL TRADE's revenues are earned mainly from annual subscriptions to its software and technology offerings (subscriptions represented approximately 75% of GL TRADE's revenues in 2005). Subscriptions generally have an initial term of two years, and are renewed annually absent notice of cancellation. Most subscription contracts are on a calendar year basis. Subscriptions are generally paid in advance. The group records revenues from subscription agreements on a pro rata basis over the life of the subscription agreements, with the unrealized portions of invoiced subscription fees recorded as deferred revenues. Because of the annual nature of subscription agreements, changes in subscription revenues typically lag developments in the markets that GL TRADE serves. Subscription fees include basic service packages. Customers are invoiced separately for GL TRADE's enhanced service packages. A portion of GL TRADE's revenues, principally for its advanced order management offering, are derived from sales of five-year software licenses, which are generally accompanied by annual maintenance and service contracts. The bulk of GL TRADE's revenues from these arrangements are recorded at the time of the license sale, while the maintenance contracts are typically renewed over time and thus generate recurrent revenues. As a result, a major license contract can have a significant impact on GL TRADE's revenues for a given period, which will not necessarily carry forward to the same extent into future periods.

Other income

The primary recurring items within other income are rental income, administrative services provided to LCH.Clearnet on a transitional basis following its creation and since July 1, 2005, charges to AEMS for the supply of transitional services provided by Euronext.

Costs and expenses

The following is a summary of Euronext's principal cost and expense categories.

Salaries and employee benefits

Salaries and employee benefits consist primarily of employee salaries and bonuses, compulsory social security contributions with respect to employees and pension expenses. Since January 1, 2004, this line item has included stock option expense recorded under IFRS 2.

Depreciation

Depreciation consists of depreciation of tangible fixed assets and intangible fixed assets (excluding goodwill) as well as write-offs on intangible assets.

Goodwill amortization

Euronext adopted IFRS 3 for all business combinations agreed on or after March 31, 2004. Starting January 1, 2005, Euronext no longer amortizes goodwill relating to acquisitions made before March 31, 2004 as part of a business combination, in line with IFRS 3. From January 1, 2005, goodwill is assessed periodically for impairment. During 2003 and 2004, goodwill amortization primarily consisted of amortization of goodwill related to Euronext's acquisition of LIFFE. The balance of goodwill primarily

364

related to the merger that led to Euronext's creation in September 2000, as well as goodwill relating to Euronext's acquisition of BVLP (Bolsa de Valores de Lisboa e Porto, now known as Euronext Lisbon).

Information technology expenses

IT expenses consist primarily of costs relating to fees paid to third-party providers of networks and information technology resources, including fees for consulting, research and development services, software rental costs and licenses, hardware rental and related fees paid to third-party maintenance providers. Since July 1, 2005, these expenses consist primarily of fees charged by AEMS for IT services relating to the operation and maintenance of Euronext's cash and derivatives trading platforms, including license fees relating to NSC and LIFFE CONNECT®.

Office, telecom and consultancy

Office, telecom and consultancy costs consist primarily of travel expenses, telecommunications expenses, fees for insurance and information services, third-party contracting fees and fees paid to consultants, (other than information technology consultants) attorneys and accountants.

Accommodation

Accommodation costs and expenses include lease payments for rented office space and related service charges for utilities, security, maintenance and cleaning and related items. Euronext is reimbursed for certain expenses by third parties, including AEMS, under sublease arrangements.

Marketing costs

Marketing costs consist primarily of advertising and other promotional expenses including costs relating to presentations, events, sponsorships, foreign offices and similar items.

Other expenses

Other expenses consist of miscellaneous costs, including irrecoverable VAT and other sundry non-income taxes, regulatory fees, production costs for information services and other miscellaneous costs.

Net financing income

Net financing income consists of interest income (primarily interest earned on short-term investments, deposits and cash balances with banks), interest expense, foreign exchange gains and losses, gains and losses on disposal of investments and gains and losses on revaluation of financial assets and liabilities the changes in fair value of which are booked in the income statement (primarily derivative instruments).

Income from associates

Income from associates consists of Euronext's share in the results of operations of associated companies (i.e., companies over which Euronext has a significant influence, but over which it does not exercise control). Euronext accounts for these entities under the equity method after taking into consideration the effect of intercompany transactions. Income from associates during the period under review primarily consisted of Euronext's share of the results of LCH.Clearnet and AEMS.

Minority interests

Minority interests during the period under review related primarily to the approximately 60% interest held by third parties in GL TRADE and, since December 2005, the interest held by minority investors in MTS.

Results of Operations for the Six Months Ended June 30, 2006 Compared to the Six Months Ended June 30, 2005

Revenues

Euronext's total revenues increased by 20.9% from €461.2 million in the first half of 2005 to €557.7 million in the first half of 2006, driven by a very high level of trading activity on Euronext markets. The following table summarizes the composition of Euronext's revenues for the first half of each of 2005 and 2006.

Cash trading

Revenue from cash trading increased by 48.9% to €150.1 million in the first half of 2006, due primarily to the continuation and acceleration of the strong recovery in market activity which started in the second half of 2005. A record level of 116 million cash transactions were executed on Euronext's cash markets in the first half of 2006, a 51.6% increase over the first half of 2005 (in which 76.5 million trades were recorded) corresponding to a daily average of approximately 915,000 trades. As a consequence, trade execution and connection fees increased 45% in the first half of 2006 to €119.9 million from €82.5 million in the first half of 2005, with the average fee per trade decreasing slightly due to Euronext's sliding fee scale. The clearing fee retrocession paid by LCH.Clearnet for trades on the Euronext cash markets increased by 65.6% to €30.3 million in the first half of 2006 from €18.3 million in the first half of 2005, driven by an increase in both transaction values and in trading volume.

Listing fees

Listing revenues increased 9.8% from €20.8 million in the first half of 2005 to €22.9 million in the first half of 2006. The increase resulted from an increase in the number of new listings from 27 in the first half of 2005 to 62 in the first half of 2006, leading to a 28% increase in admission fees to €15.7 million. Of the 62 new listings in the first half of 2006, 28 were listed on Alternext. The increase in admission fees was partially offset by a decline in annual fees, which fell by 2% to €6.7 million in the first half of 2006, reflecting delistings or mergers during the year. As of June 30, 2006, 1,224 companies were listed on Euronext, compared to 1,293 companies as of June 30, 2005.

Derivatives trading

Revenue from derivatives trading increased by 26.4% to €205.0 million in the first half of 2006, driven primarily by higher volumes across the main markets and products and, to a lesser degree, by the launch in November 2005 of fully integrated transactional products, Afirm, Cscreen and Bclear. Overall, the increased volumes resulted from market volatility, strong cash markets activity and interest rate

366

uncertainty. Overall volumes (excluding call option dividend trading activity) were 26.6% higher in the first half of 2006 than the first half of 2005, increasing from 305.4 million contracts to 386.8 million contracts. Volumes were higher in all major product categories: interest rate products increased by 18.3%, equity products by 39% and commodity products by 6%. It should be noted for purposes of this discussion (and for ease of comparison) that volume figures for the first half of 2005 have been restated to reflect changes made in the second half of 2005 to the notional sizes of various contracts, i.e., they have been treated as if they were new-style contracts by dividing their volumes by ten.

Trading revenues from interest rate products amounted to €120 million in the first half of 2006, a 26.2% increase over the first half of 2005. The increase was due primarily to an 18.3% increase in the number of contracts traded to 209.8 million, itself due to higher volatility induced by on-going speculation over interest rate trends (and in particular interest rate decisions of the European and UK central banks). The fact that the Euro dollar contract, which negatively affected results in the first half of 2005, was not offered in 2006 also contributed to the increase in revenues.

Equity derivatives trading revenues increased by 32.5% to €65.6 million in the first half of 2006, of which €5.9 million related to OTC trading. Excluding Bclear, volumes increased by 13% due in particular to the high level of trading activity on the cash markets. Bclear itself generated 32.8 million contracts traded in the first half of 2006; it had not been operational in the first half of 2005.

Commodity product trading revenues increased by 7.3% to €6.1 million in the first half of 2006, driven by a 6% increase in volume, with an additional 4.6 million contracts traded.

As a consequence of the change in the underlying contract sizes in the French market (which mechanically reduced the number of contracts traded), the clearing fee retrocession paid by LCH.Clearnet for continental derivatives trading decreased by 79% to €0.7 million in the first half of 2006.

MTS Fixed Income

Euronext's share of MTS' revenues amounted to €12.4 million in the first half of 2006. There were no corresponding revenues in the first half of 2005, as Euronext acquired MTS (via its joint venture with Borsa Italiana) in November 2005. On a comparable basis and for informational purposes only, Euronext's share of MTS' revenues would have amounted to €12.2 million in the first half of 2005 had Euronext held the same interest in MTS during such period.

Settlement and custody

The 68.1% decrease in settlement and custody revenues between the periods is due to the sale, effective January 1, 2006, of CIK, which had accounted for €12.2 million of revenues in the first half of 2005. Settlement and custody revenues in the first half of 2006, which amounted to €7 million, were generated solely by Interbolsa. These were 28% lower than those generated by Interbolsa in the first half of 2005, as a result of a change in fee structure in January 2006 and certain one-off revenues (relating to a restructuring of a Portuguese company) recorded in 2005.

Information services

Information services revenues increased 23.7% to €54.3 million for the first half of 2006. The increase resulted partly from revenues generated by newly consolidated companies (€1.7 million from MTS and €1.4 million from Companynews). The increase on a stand-alone basis was 17% and was due mainly to increases in the number of both cash and derivatives terminals receiving Euronext data and to the positive effect of the harmonization of the derivatives information services package implemented in July 2005.

367

Sale of software

The 12.9% decrease in revenue from the sale of software from €103.2 million in the first half of 2005 to €89.9 million in the first half of 2006 is due to the transfer of LIFFE Market Solutions to AEMS in July 2005. First half 2005 revenues included €16.2 million of software revenues generated by licenses of the LIFFE CONNECT® product by LIFFE Market Solutions, whereas first half 2006 revenues consisted solely of revenues generated by GL TRADE. GL TRADE's revenues increased by 3.4% (or €3 million) between the periods. Of this increase, €1.6 million was generated through its subsidiary OASIS, acquired in July 2005.

Other income

Other income nearly doubled from €8.2 million in the first half of 2005 to €16.1 million in the first half of 2006. The increase is due principally to €6.3 million in services charged to AEMS (versus none in the first half of 2005 prior to the transfer of LIFFE Market Solutions to AEMS), as well as income from services (mainly IT) provided to unconsolidated local MTS markets (€1.4 million).

Costs and expenses

Euronext's total costs and expenses increased by 5.1% to €337.4 million in the first half of 2006. The following table summarizes costs and expenses for the first six months of 2005 and 2006.

	Six months ended June 30,

Total costs and expenses	337,404	321,104	5.1	%

Changes in scope of consolidation affecting costs

The comparability of expenses between the first six months of 2005 and 2006 is affected by several changes in scope of consolidation between the periods.

Creation of Atos Euronext Market Solutions

On July 22, 2005, Euronext formed Atos Euronext Market Solutions as a continuation and expansion of its existing AtosEuronext relationship with Atos Origin. The main assets Euronext contributed were the activities of LIFFE Market Solutions, the information technology division of its derivatives trading business Euronext.liffe (including Euronext's proprietary LIFFE CONNECT® electronic trading system), and its 50% stake in AtosEuronext. Atos Origin contributed its own 50% share in AtosEuronext, plus other major assets from market-related businesses, including middle- and back-office solutions, and its 51% stake in the connectivity platform Bourse Connect.

The transfer of the activities of LIFFE Market Solutions to AEMS led to a significant reduction in Euronext's salaries and employee benefit costs, consultancy expenses, other office, telecom and consultancy costs and depreciation charges, and a parallel increase in IT expenses, which now include all

368

IT expenses related to Euronext.liffe. The transfer of LIFFE Market Solutions to AEMS represented in the aggregate a €9.9 million reduction in costs from the first half of 2005 to the first half of 2006.

Other Changes

Euronext acquired MTS in November 2005 through a joint-venture entity with Borsa Italiana, acquired 100% of Companynews in March 2006 and sold CIK effective January 1, 2006. In the aggregate, newly consolidated MTS and Companynews added €11.3 million and €1.4 million in costs, respectively, for the first half of 2006, and the sale of CIK reduced costs by €8.1 million in such period.

Salaries and employee benefits

Salaries and employee benefits expenses decreased 0.7% from €131.6 million in the first half of 2005 to €130.7 million in the first half of 2006. This resulted from a reduction in headcount at Euronext's entities other than MTS, Companynews and GL TRADE. Excluding such entities, Euronext had 361 fewer full-time employees at June 30, 2006 than June 30, 2005, a reduction of 25.6% that resulted primarily from the transfer of 207 employees from LIFFE Market Solutions to AEMS in July 2005 and the sale of CIK (itself leading to a headcount reduction of 102 employees).

This lower headcount more than offset the impact of a 1% (€0.4 million) increase in GL TRADE's staff costs, Euronext's share (€3.8 million) of staff costs at MTS (99 full-time employees as of June 30, 2006) and €0.6 million of staff costs at Companynews (25 employees), as well as a number of specific increases including €2.1 million related to past and new stock option grants, €2 million of additional employee profit sharing expense and €2.3 million of additional redundancy costs.

Depreciation

Depreciation expense amounted to €14.2 million in the first half of 2006, 57.2% less than the €33.3 million recorded in the first half of 2005. This is due primarily to the transfer of LIFFE Market Solutions' IT-related tangible and intangible assets to AEMS as of July 1, 2005; depreciation expense related to these assets had amounted to €21.3 million in the first half of 2005. Excluding the effect of this transfer, depreciation expense increased by €2.1 million from period to period, due to a combination of increases in London, Amsterdam and GL Trade (€2.1 million, €0.7 million and €0.7 million) and the consolidation of MTS (€0.3 million) which offset the effect of the completion of amortization of certain assets in Paris (€1 million effect) and a €0.6 million decrease in amortization in Brussels due to the sale of CIK.

Information technology expenses

IT expenses increased by 45.7% to €82.4 million in the first half of 2006. This increase resulted primarily from the transfer of LIFFE Market Solutions' activities to AEMS, which accounted for €35.1 million of additional IT costs. In addition, Euronext's share of IT expenses at MTS amounted to €4.9 million. These increases more than offset stand-alone cost reductions in Paris, London and Amsterdam totaling €10 million and a €3 million reduction resulting from the sale of CIK. Excluding the first-time impact of the transfer of LIFFE Market Solutions' activities to AEMS and Euronext's share of IT expenses at MTS, IT expenses decreased by 25%, reflecting the rationalizations effected throughout 2005.

Office, telecom and consultancy

Office, telecom and consultancy expense increased 24.9% to €64.3 million in the first half of 2006, resulting primarily from an additional €11.3 million of costs relating to corporate transactions as well as higher advisory costs particularly in GL Trade. These additional costs more than offset the reductions

369

resulting from the transfer of LIFFE Market Solutions to AEMS and the sale of CIK (€5.4 million and €0.7 million, respectively).

Accommodation

Accommodation costs decreased by 13.4% to €22.8 million in the first half of 2006. This decrease resulted from the transfer of LIFFE Market Solutions to AEMS and sale of CIK (accounting for differences of €1.6 million and €0.8 million, respectively) and a €1.3 million decrease in maintenance expenses. Maintenance expenses in the first half of 2005 had been unusually high due to one-off improvement projects, maintenance operations and cleaning services). These reductions more than offset the €0.4 million of additional accommodation expense from MTS.

Marketing

Marketing costs increased 48.0% to €11 million in the first half of 2006, due primarily to a major corporate advertising campaign implemented during the period as well as sponsorship initiatives targeted at developing proprietary business in the UK.

Other expenses

Other expenses decreased 16.4% to €12.1 million in the first half of 2006. The principal reason for the decrease was a €2.9 million reduction in VAT resulting from the transfer of LIFFE Market Solutions to AEMS, as well as a €0.3 million reduction in compulsory professional fees.

(1): Holding & Unallocated includes central office charges at the group level as well as corporate transaction costs. Revenues for this segment consist of "Other income", as described above.

Euronext's operating profit increased as a percentage of revenues from 30.4% in the first half of 2005 to 39.5% in the first half of 2006. This increase was driven by strong increases in operating profit margin in cash trading and derivatives trading, itself resulting from buoyant trading conditions and strict cost control. Holding and unallocated expenses increased due primarily to an increase in corporate transactional expenses.

	Net profit attributable to shareholders of the parent company	193,691		98,389		96.9	%

Net financing income

Net financing income increased 17.4% to €8.3 million, due to an increase in market interest rates in Europe. Since January 2006, Euronext's equity investments have been recorded as available-for-sale financial assets, variations in the fair value of which are recorded within shareholders' equity. During 2005, these variations in fair value were recorded under net financing income, and amounted to €0.6 million in the first half of 2005.

Gain on sale of associates and activities

The sale of CIK in January 2006 resulted in a capital gain of €15.5 million.

Income from associates

Income from associates increased from €2.7 million in 2005 to €19.3 million in 2006. This increase resulted primarily from improved performance by LCH.Clearnet, which contributed €14 million of income in the first half of 2006. This contribution was made notwithstanding the recognition by LCH.Clearnet in the first half of 2006 of a €47.8 million charge to write off certain IT-related assets (relating to its Generic Clearing System initiative), following a €20.1 million write-off of assets related to such initiative in the first half of 2005. The contribution of AEMS amounted to €4.6 million, as compared with the €0.6 million contribution from Atos Euronext in the first half of 2006, reflecting the larger size of AEMS.

Income tax expense

Income tax expense increased from €44.7 million in the first half of 2005 to €64.3 million in the first half of 2006, primarily as a result of increased profit for Euronext. Partially offsetting the effect of increased profitability was a €11 million adjustment, in light of the change in French tax law adopted in 2004, of Euronext's deferred tax assets relating to the sale of Clearnet to LCH.Clearnet to reflect a reduced capital gain tax rate applicable in 2007 when the related positions can be liquidated.

371

Minority interests

Minority interests decreased by 18.7% primarily due to decreased net profits at GL TRADE and despite the presence of additional minority interest following the acquisition of MTS.

Net profit attributable to shareholders of the parent company

For the reasons discussed above, net profit after tax and minority interests, increased by 96.9% from €98.4 million for the six months ended June 30, 2005 to €193.7 million for the six months ended June 30, 2006.

Cash trading

Revenue from cash trading increased by 13.7% to €215.7 million in 2005, due primarily to a strong recovery in market activity in the second half of 2005 that drove an 11.6% increase in trade execution fees, order fees and connection fees and a 23.5% increase in the related clearing fee retrocession for trades on the cash markets cleared by LCH.Clearnet.

A record 155.5 million share transactions were executed on Euronext's cash markets in 2005, up 15.7% over 2004. The total number of trades in all cash products amounted to 162 million during 2005 (an increase of 15.0% over 2004), corresponding to a daily average of 632,000 trades (an increase of 15.8% over 2004).

The recovery in market activity was driven primarily by a recovery in the confidence in the profitability of listed companies, as illustrated by rising indices, and a solid market for primary offerings, including

372

some major IPOs. NextTrack, Euronext's tracker market segment, recorded a 28.5% increase in the number of transactions and a 38.0% increase in value traded during 2005, due in part to the creation of 40 new products in 2005, which brought the total number of trackers to 95 at year end, as well as to the creation of partnerships with e-brokers. The number of transactions (excluding cross-trades) on NextWarrants, Euronext's segment for certificates and warrants, grew by 46% compared to 2004.

Higher trading volumes were also encouraged by a new fee structure introduced in February 2005 that includes volume discounts designed to promote higher activity. Trade execution fees alone amounted to €163.1 million in 2005, an increase of 11.7% over 2004. The increase in trading volumes described above helped to offset a reduction in the average fee charged per trade (excluding liquidity provider trades), from €1.07 in 2004 to €1.03 in 2005.

The clearing fee retrocession paid by LCH.Clearnet in 2005 increased by 23.5% to €41.1 million, compared to €33.3 million in 2004. The increase was driven by an increase in transaction values, as well as by an increase in trading volume.

Listing fees

Revenue from listing fees increased 45.9% to €63.1 million in 2005. This increase resulted primarily from a significant increase in admission fees, which more than doubled to €47.5 million in 2005. The increase in admission fees was driven by higher IPO activity. 78 IPOs were completed during 2005, compared to 52 during 2004, raising €17.2 billion and adding €105 billion in additional market capitalization. Two of these IPOs—those of EDF S.A. and GDF S.A.—were among the largest in Europe in recent years. Of the 78 IPOs in 2005, 20 were listed on Alternext, a new exchange-regulated market targeted at SMEs launched in May 2005. The increase in admission fees was also favorably affected by strong listing activity for warrants, with approximately 11,000 new warrants and certificates listed in 2005, up 4% compared to 2004.

The increase in admission fees was partially offset by a decline in annual fees, which fell by 5% to €13.6 million in 2005, reflecting delistings during the year, principally by companies with listings in multiple markets. At the end of 2005, 1,259 companies were listed on Euronext, compared to 1,333 companies at the end of 2004. 966 of the companies listed at the end of 2005 were companies based in one of Euronext's home markets.

Derivatives trading

Revenue from derivatives trading increased 2.2% to €331.9 million in 2005, driven primarily by higher trading revenues from short-term interest rate products and commodity derivatives, which more than offset a decrease in trading revenues from equity derivatives.

In 2005, changes were made to the notional sizes of various contracts in response to customer demand. To enable year-on-year comparisons of changes in volume, 2004 volume figures below have been treated as if they were new-style contracts by dividing their volumes by ten. Overall volumes (excluding call option dividend trading activity) were 7.0% higher in 2005, increasing from 566.1 million contracts in 2004 to 605.9 million in 2005. Volumes were higher in all major product categories: interest rate products increased by 10.8%, equity products by 2.1% and commodity products by 6.0%. Open interest stood at 78 million contracts, up 13% over 2004 (at 69 million contracts after rebasing of the underlying contract sizes in Paris, or 88.4 million without rebasing). Higher levels of open interest—which consists of the total number of futures contracts or option contracts that have not yet been exercised, expired or fulfilled by delivery—can be the source of revenue growth due to the likely management of these positions.

Trading revenues from interest rate products amounted to €193.4 million in 2005, a 10% increase over 2004. Trading volumes in interest rate products ended the year 10.8% higher than in 2004, with more than 347 million contracts traded, driven primarily by an increase in trading in the second half of the year due to

373

higher volatility resulting from expected changes in the European Central Bank's interest rate policy following a long period of stability.

Equity derivatives trading revenues declined by 7.5% in 2005 to €102.4 million. Equity derivatives trading volume was 2.1% higher for the year, driven primarily by activity in the second half of the year due to higher volatility in the financial markets. The modest increase in overall volume for the year was more than offset by lower average fees, primarily reflecting the impact of fee decreases for single equity options introduced in November 2004.

Commodity product revenues increased by 4.0% to €11.1 million in 2005, driven by a 6.0% increase in volume, increased rebates in London and a change in the business mix in Amsterdam.

The clearing fee retrocession paid by LCH.Clearnet for continental derivatives trading in 2005 decreased by 21.3% to €5.8 million, primarily as a result of lower trading volumes in the Paris derivatives market and the change in the underlying contract sizes in the French market (which had the mechanical effect of reducing the number of contracts traded).

MTS Fixed Income

Euronext proportionately consolidated 51.0% of MTS (via MBE Holding) for one month in 2005, following its acquisition in late November, recording proportionately consolidated revenues of €1.4 million.

Settlement and custody

Revenues from settlement and custody services amounted to €39.3 million in 2005, an increase of 18.6% over 2004, driven primarily by higher indices, a strong performance in 2005 by new products launched by Euronext Brussels in 2004 and certain one-off transactions (such as the restructuring of a Portuguese company) on Euronext Lisbon.

Information services

Revenue from information services increased 7.2% to €93.6 million in 2005, driven primarily by a 5% increase in fees charged for real-time cash market data. Revenues were also positively affected by an increase in the number of end-users in the financial services industry, the introduction of a harmonized derivatives trading data offering beginning in July 2005 and the launch of Euronext's Index File Service and NextHistory products.

Sale of software

Revenue from the sale of software increased 5.0% to €195.2 million in 2005, of which €179.3 million, or 91.8%, was generated by GL TRADE. The remaining €15.9 million of software revenues for 2005 were generated by licenses of the LIFFE CONNECT® product by LIFFE Market Solutions prior to the contribution of LIFFE Market Solutions to AEMS in July 2005.

GL TRADE generated revenues of €179.3 million in 2005, an increase of €29.3 million, or 18.8%, over 2004, primarily reflecting the positive impact of the November 2004 acquisition of Ubitrade S.A. and Davidge Inc. The increase in revenues resulted primarily from sales of risk management and back-office product lines originally developed by Ubitrade, which generated €32.3 million of revenues in 2005. Of the Ubitrade product revenues, €13.0 million were attributable to the UBIX post-trade derivatives product line, €4.4 million were attributable to the TRADIX risk management product line and €14.9 million (including non-recurring license fees and a significant proportion of outsourced consulting services) were attributable to the FERMAT product line, a credit risk management tool that meets the requirements of the new Basel II regulatory regime for banking institutions.

The positive impact of the Ubitrade acquisition more than offset a decline in GL TRADE's revenues from its traditional front-office business lines, which continued to be negatively affected by consolidation in the financial services sector, particularly in France and Italy, as this reduces GL TRADE's accessible client

374

base. Front-office revenues were also negatively affected by the decisions of several international financial institutions to shut down or reduce their trading operations in the UK and Italy. Overall, front-office revenues declined by 1% to €133.4 million in 2005, a figure that also reflected in part the positive impact of new front-office revenues generated by the Davidge acquisition.

Although GL TRADE faced difficulties in its traditional European markets, sales of front-office products in the Asia-Pacific region recorded organic revenue growth of more than 19% in 2005. GL TRADE's expansion into Eastern Europe showed promising signs as well during 2005, recording revenues of nearly €1.5 million in Russia, where it opened an office at the end of 2005. In the United States, revenues increased by 52.0% compared to 2004, reflecting the integration of Ubitrade S.A., Davidge Inc. and OASIS.

Other income

Other income decreased 4.3% to €21.6 million in 2005, primarily reflecting a decrease in rental revenues following the termination of a sublease to LCH.Clearnet in Paris, and a €2.9 million decrease in transitional services fees collected from LCH.Clearnet due to its increased self-sufficiency. These items were partially offset by €5.9 million in charges to AEMS during the six months beginning July 1, 2005.

Costs and expenses

Euronext's total costs and expenses decreased 6.3% to €643.4 million in 2005, primarily due to the fact that goodwill was no longer amortized as of January 1, 2005. The following table summarizes costs and expenses for 2004 and 2005.

	Year ended December 31,
	Year ended December 31,		% Change 2005/2004
	2005	2004	% Change 2005/2004
	(in thousands of euros)

IT expenses	139,772	129,336	8.1	%
Office, telecom and consultancy	98,785	84,392	17.1	%
Accommodation	50,111	50,990	(1.7	)%
Marketing	15,586	15,250	2.2	%
Other expenses	25,088	27,434	(8.6	)%

Total costs and expenses	643,389	686,659	(6.3	)%

Salaries and employee benefits

Salaries and employee benefits decreased 2.8% from €272.0 million in 2004 to €264.4 million in 2005, primarily as a result of a reduction in headcount at Euronext's operations other than MTS and GL TRADE. Euronext had 268 fewer full-time employees in its operations other than MTS and GL TRADE at the end of 2005 than at the end of 2004, a reduction of 18.6% that resulted primarily from the transfer of 207 employees from LIFFE Market Solutions to AEMS in July 2005.

These headcount reductions more than offset the impact of a 17.1% (€12.5 million) increase in GL TRADE staff costs, primarily reflecting the impact of a full year of staff costs from Ubitrade and Davidge compared to only one and two months, respectively, in 2004, and an increase of €2.1 million in stock option expense at Euronext and GL TRADE compared to 2004.

In late November 2005, Euronext acquired an indirect interest in MTS, which had 98 full-time employees at the end of 2005.

375

Depreciation

Depreciation expense decreased by €17.7 million, or 26.3%, to €49.7 million in 2005, primarily as a result of the transfer of LIFFE Market Solutions' IT-related tangible and intangible assets to AEMS as of July 1, 2005, which resulted in savings of €18.0 million. The decrease also reflects the recording in 2004 of a €9.0 million write-off at Euronext.liffe following the migration of LIFFE CONNECT®. These decreases were partially offset by the migration of the Euronext Amsterdam derivatives market from SWITCH to LIFFE CONNECT® at the end of 2004 and various other capital expenditures that led to new depreciation charges in 2005. In addition, Euronext recorded €3.4 million in amortization of certain intangible assets in GL TRADE in 2005.

Goodwill amortization

Euronext adopted IFRS 3 for all business combinations agreed on or after March 31, 2004. Starting January 1, 2005, Euronext no longer amortizes goodwill relating to acquisitions made before March 31, 2004 as part of a business combination in line with IFRS 3. From January 1, 2005, goodwill is assessed periodically for impairment. Accordingly, there was no goodwill amortization expense in 2005. In 2004, goodwill amortization totaled €39.9 million and related primarily to Euronext's acquisition of LIFFE (€24.9 million), the merger that led to Euronext's creation in September 2000 (€9.1 million), and goodwill relating to Euronext's acquisition of BVLP (€4.0 million).

Information technology expenses

IT expenses increased by €10.4 million, or 8.1%, to €139.8 million in 2005. This increase resulted primarily from the transfer of LIFFE Market Solutions' activities to AEMS, which accounted for €27.9 million in additional IT costs, and a €3.1 million increase in IT costs at GL TRADE during 2005 as a result of external growth. These increased expenses were partially offset by an aggregate €22.0 million decrease in other IT costs, resulting primarily from the completion of the derivatives market IT migration in Amsterdam in November 2004, which caused IT operating costs in continental Europe to fall by €16.4 million to €64.3 million in 2005, and a lower number of working days billed to Euronext for software development.

Office, telecom and consultancy

Office, telecom and consultancy expense increased 17.1% from €84.4 million in 2004 to €98.8 million in 2005, due to expenses relating to the envisaged acquisition of the London Stock Exchange (€16.6 million) and external growth at GL TRADE (€8.7 million). This increase was partially offset by a €6.0 million reduction in consultancy costs relating to the transfer of LIFFE Market Solutions to AEMS.

Accommodation

Accommodation costs decreased 1.7% to €50.1 million in 2005, primarily reflecting the full year impact of the termination of certain leases (one in Paris and six in London) as well as a number of new subletting contracts that helped to decrease costs. This decrease was partially offset by a 14.0% increase in accommodation costs at GL TRADE, stemming from its external growth.

Marketing

Marketing costs increased 2.2% from €15.3 million in 2004 to €15.6 million in 2005, due primarily to higher advertising and related costs in connection with the geographic expansion of Euronext's derivatives trading markets.

Other expenses

Other expenses decreased 8.6% to €25.1 million in 2005, primarily reflecting lower expenses for non-recoverable VAT and lower regulatory fees, partially offset by an increase in administrative costs and commissions.

(1): Holding & Unallocated includes central office charges at the group level as well as corporate transaction costs. Revenues for this segment consist of "Other income", as described above.

Euronext's operating profit increased as a percentage of revenues from 22.6% in 2004 to 33.1% in 2005. Revenues grew faster than costs and expenses in all segments other than the sale of software, where the decline in margins reflected in part, the impact of integrating Ubitrade and Davidge for the full year in 2005. In addition, as noted above, goodwill is no longer amortized beginning January 1, 2005.

Other Items affecting Net Profit

377

Net financing income

Net financing income increased 75.1% from €7.7 million in 2004 to €13.4 million in 2005, primarily as a result of a net foreign exchange gain of €1.0 million in 2005 compared to a €4.4 million loss in 2004.

Gain on sale of associates and activities

Euronext recorded gains of €5.0 million and €4.1 million on the transfer of LIFFE Market Solutions and Bourse Connect, respectively, to AEMS in July 2005. In 2004, Euronext recorded a gain of €4.4 million on the sale of Cote Bleue S.A.

Income from associates

Income from associates increased from €3.3 million in 2004 to €18.5 million in 2005, which primarily reflected the absence during 2005 of goodwill amortization relating to the acquisition of LCH.Clearnet, since goodwill is no longer amortized under IFRS. In 2004, goodwill amortization relating to the acquisition of LCH.Clearnet amounted to €12.3 million. The increase in income from associates during 2005 was also partially due to an increased contribution from AEMS. AEMS contributed €5.0 million in 2005, compared to the €1.9 million contribution from AtosEuronext in 2004, largely reflecting the larger size of AEMS. This increase was partially offset by a lower contribution from Bourse Connect during 2005 of €0.9 million (compared to €1.5 million in 2004), which was contributed to AEMS in July 2005.

Income tax expense

Income tax expense increased from €54.8 million in 2004 to €104.3 million in 2005, primarily as a result of increased profit for Euronext. In addition, during 2004 the French government enacted legislation through which the capital gains tax will be reduced in the years up to 2007. As a result, Euronext's deferred tax positions were adjusted in 2004 to reflect the expected tax rates when the related positions could be liquidated. This resulted in a €27.3 million reduction in income tax expense for 2004.

Minority interests

Minority interests increased by 21.7% primarily due to increased net profits of GL TRADE.

Net profit attributable to shareholders of the parent company

For the reasons discussed above, net profit after goodwill amortization, tax and minority interests, increased 61.5% from €149.7 million in 2004 to €241.8 million in 2005.

Results of Operations for the Year Ended December 31, 2004 Compared to the Year Ended December 31, 2003

Basis of Presentation

On December 22, 2003, Euronext transferred its 80.48% stake in the share capital of BCC/Clearnet and 17.7% of LCH (the latter held through LIFFE) to a newly-formed entity, LCH.Clearnet Group Limited, in exchange for 49.1% of share capital of the newly formed company and simultaneously sold 7.6% of the company's ordinary shares to third parties. Euronext's remaining interest in LCH.Clearnet Group Limited consists of 16.6% of total capital in the form of Redeemable Convertible Preference Shares (RCPSs) and 24.9% of total capital in the form of ordinary shares. The preference shares are intended to be either redeemed by December 2008 at the latest or to be sold earlier. The net assets, results and cash flows of BCC/Clearnet were fully consolidated in the Euronext consolidated accounts in the period prior to December 22, 2003. As of that date, the assets and liabilities of BCC/Clearnet have been deconsolidated.

378

Since the sale of BCC/Clearnet on December 22, 2003, Euronext's clearing revenues have consisted solely of retrocession fees received from LCH.Clearnet. Subsequent to the sale of BCC/Clearnet, Euronext began recording these fees as part of cash trading and derivatives trading revenues. Prior to the sale of BCC/Clearnet, Euronext included these fees under the separate line item "Clearing." Euronext's clearing operations were treated as a separate segment.

Revenues

Euronext's total revenues decreased by 10.5% from €991.0 million in 2003 to €886.8 million in 2004, primarily due to the sale of Clearnet at the end of 2003. The following table summarizes the composition of Euronext's revenues for 2003 and 2004.

(1): Effective January 1, 2004, clearing revenue in the form of retrocession fees received from LCH.Clearnet is included in cash trading and derivatives trading revenues.

Cash trading

Revenue from trade and connection fees cash trading decreased 16.6% to €156.4 million in 2004, primarily as a result of lower levels of trading activity, ongoing consolidation in the brokerage industry and a new fee structure implemented in January 2004 that reduced the average trading fee (excluding connections) to €1.07 per trade. Average prices were also affected by the introduction of price incentives in April 2004 for all members trading Dutch securities.

In terms of volume, although the first quarter of 2004 was marked by high levels of activity which led to record trading volumes in March (in particular IPO activity, as discussed below under "Management's Discussion and Analysis of Financial Condition and Results of Operations of Euronext—Results of Operations for the Year Ended December 31, 2004 Compared to the Year Ended December 31, 2003—Listing fees"), the terrorist attacks in Madrid later that month had a strong negative impact on the markets. This marked the beginning of a drop in volatility on both the equity and interest rate markets,

379

which led to a decline in activity on both markets that brought volumes down further each month, reaching a low point in August. Although the capital markets enjoyed a limited rebound at the end of 2004 following the end of uncertainty over U.S. elections, Euronext's cash trading volumes declined overall during 2004. The total number of trades in all cash products amounted to 141 million during 2004 (a decrease of 6% over 2003), corresponding to a daily average of 545,870 trades (a decrease of 5.3% over 2003).

Following the sale of BCC/Clearnet in December 2003, retrocession fees received from LCH.Clearnet are included in cash trading revenues effective January 1, 2004. These fees amounted to €33.3 million in 2004.

Listing fees

Revenue from listing fees increased by 41.2% to €43.3 million in 2004. This increase primarily resulted from an 82.0% increase in admission fees, which amounted to €29.0 million in 2004. The increase in admission fees was driven by a recovery in IPO activity on Euronext (52 IPOs were completed during 2004, compared to 38 during 2003, raising a total of €9.4 billion in capital). Euronext handled a number of major IPOs, such as Autoroutes Paris-Rhin-Rhône (SAPRR), Pages Jaunes, Snecma and Belgacom, the latter of which was the biggest IPO in Europe in 2004. A number of significant tender offers also took place, including Sanofi-Aventis. The increase in admission fees was partially offset by a 3.0% decline in annual fees during 2004, to €14.3 million, as a result of delistings throughout the year.

At the end of 2004, 1,333 companies were listed on Euronext (compared to 1,392 companies at the end of 2003), of which 999 were based in one of Euronext's home markets (Belgium, France, the Netherlands and Portugal).

Derivatives trading

Revenue from order fees derivatives trading increased by 5.9% to €317.5 million in 2004, due primarily to a 14% increase in volumes during 2004 to more than 790 million (non-rebased) contracts, representing a notional value of €283.3 trillion. Euronext recorded increased volumes in all product categories during 2004: interest rate products increased by 14%, equity products by 14% and commodity products by 21%. Open interest stood at 88 million contracts, up 12% over 2003. The higher volumes were offset in part by lower average fees. In November 2004, Euronext.liffe lowered its fees for equity options trading in the Amsterdam, Brussels, London and Paris derivatives markets, reducing the cost of trading by an average of 25%.

In the category of interest rate products, interest rate futures volumes increased 20% compared to 2003, while option volumes decreased slightly by 2%. Euribor futures recorded a solid performance in 2004 (up 15% over 2003), as did sterling futures (up 21%) and long gilt (up 38%). Because the European Central Bank did not modify its interest rate policy during 2004, Euribor option volumes were down 10% compared to 2003. The Bank of England, however, raised interest rates four times over the course of the year, leading to a 51% increase in Sterling option volumes compared to 2003.

In the category of equity products, products based on individual equities were up 26% overall compared to 2003, with futures rising 93% and options 24%, driven by increased volatility in equity markets. However, equity index products decreased by 5% compared to 2003. Index futures fell by 7%, while index options declined by 4%, due to a decrease in CAC 40 contract volumes.

Following the sale of BCC/Clearnet in December 2003, retrocession fees received from LCH.Clearnet are included in derivatives trading revenues effective January 1, 2004. These fees amounted to €7.4 million in 2004.

380

Settlement and custody

Revenues from settlement and custody services amounted to €33.1 million in 2004, an increase of 17.3% over 2003, benefiting from the recovery in securities prices, which had a positive impact on custody revenues generated, as well as higher dividend payments.

Information services

Revenue from information services decreased 4.2% from €91.2 million in 2003 to €87.3 million in 2004. Although the level of subscriptions for information services remained stable, revenues declined due to the elimination of terminal fees previously charged by Euronext Lisbon following integration of Euronext Lisbon data into the overall Euronext data feed.

Sale of software

Revenue from sale of software increased 7.8% from €172.5 million in 2003 to €186.0 million in 2004, due primarily to GL TRADE's continued geographic expansion. GL TRADE's revenues increased by 17.5% to €150.1 million in 2004 as a result of its external growth. Additional revenue was generated by the newly integrated entities GLESIA in Italy and the Misys subsidiaries in the UK, Japan and Hong Kong, which were all acquired at the end of 2003, as well as €2.7 million generated by Davidge and Ubitrade following their acquisition in the fourth quarter of 2004.

Organic growth was limited in 2004 due to the maturity of certain markets, such as France where consolidation in the banking sector was the major factor behind lower revenues (down 11%,). Nevertheless, satisfactory levels of organic growth were recorded in Asia and the U.S., despite the weak dollar. GL STREAM revenues rose 22.0% to €95.0 million, offset in part by a 9.0% decline in revenues from GL NET to €21.1 million, and market data activities rose 1% to €16.2 million. Settlement revenues rose from €1.1 million in 2003 to €7.4 million in 2004, supported by the November 2004 acquisition of Ubitrade.

Clearing

No revenues were recorded as "clearing revenue" in 2004, reflecting the sale of BCC/Clearnet to LCH.Clearnet in December 2003. As discussed above, revenues previously recorded as clearing revenues were included in cash trading and derivatives trading revenues effective January 1, 2004. In 2003, clearing revenues of €165.1 million were generated by BCC/Clearnet.

Other income

Other income increased 41.1% from €16.0 million in 2003 to €22.5 million in 2004, due primarily to €7.5 million billed to LCH.Clearnet for transitional services rendered in 2004.

Costs and expenses

Euronext's total costs and expenses decreased 12.2% to €686.7 million in 2004, reflecting the sale of BCC/Clearnet on December 22, 2003, which more than offset a 2.5% increase in costs and expenses from

381

Euronext's remaining operations. The following table summarizes the major components of costs and expenses for 2003 and 2004.

	Year ended December 31,
	Year ended December 31,		% Change 2004/2003
	2004	2003	% Change 2004/2003
	(in thousands of euros)
Salaries and employee benefits	271,996	267,763	1.6	%
Depreciation	67,386	67,575	(0.3	)%
Goodwill amortization	39,875	64,793	(38.5	)%
IT expenses	129,336	187,781	(31.1	)%
Office, telecom and consultancy	84,392	86,169	(2.1	)%
Accommodation	50,990	52,919	(3.6	)%
Marketing	15,250	19,271	(20.9	)%
Other expenses	27,434	35,902	(23.6	)%

Total costs and expenses	686,659	782,173	(12.2	)%

Salaries and employee benefits

Salaries and employee benefits increased by 1.6% to €272.0 million in 2004, reflecting a 9.2% increase in salaries and employee benefits from Euronext's non-clearing operations that was largely offset by expense reductions attributable to the sale of BCC/Clearnet. Of the €22.9 million increase in costs from Euronext's remaining operations, €12.1 million related to GL TRADE's ongoing growth and expansion, €9.0 million related to other expenses including one-off redundancy packages paid to departing employees and €1.5 million related to foreign exchange variation. Partially offsetting these increases was a drop in headcount at Euronext's operations other than GL TRADE during 2004. At the end of 2004, 1,437 full-time employees (excluding GL TRADE) were working at Euronext, 11.6% less than the 1,625 full-time employees (excluding Clearnet and GL TRADE) in 2003.

Depreciation

Depreciation expense decreased by 0.3% to €67.4 million in 2004, primarily reflecting the sale of BCC/Clearnet, which more than offset a 12.3% increase in depreciation expenses from Euronext's remaining operations due primarily to a €9.0 million write-off at Euronext.liffe following the end of the migration to LIFFE CONNECT®.

Goodwill amortization

Goodwill amortization decreased 38.5% from €64.8 million in 2003 to €39.9 million in 2004. The decrease was primarily due to the recording of goodwill impairment losses in 2003 of €13.8 million in connection with the acquisition of Euronext Lisbon. In addition, following the sale of BCC/Clearnet in 2003, the corresponding annual goodwill amortization charge (which amounted to €11.8 million in 2003) was no longer recorded. In 2004, goodwill amortization related primarily to Euronext's acquisition of LIFFE (€24.9 million). The remainder of goodwill amortization in 2004 primarily related to the merger that led to Euronext's creation in September 2000 (€9.1 million), as well as goodwill relating to Euronext's acquisition of BVLP (€4.0 million).

Information technology expenses

IT costs decreased 31.1% to €129.3 million in 2004, reflecting the sale of BCC/Clearnet as well as a 12.9% decrease in IT costs from Euronext's remaining operations. This decrease was primarily due to the synergies generated by Euronext's multi-year IT migration program, which was completed upon the

382

Amsterdam derivatives market migrating to LIFFE CONNECT® in November 2004. IT costs related to AtosEuronext were €95.3 million (of which €7.5 million were capitalized), representing a €17.0 million drop in operating costs compared to 2003. In addition, the number of working days charged to Euronext for development decreased by 26% compared to 2003, reflecting a reduced need for development following the completion of the IT migration. Partially offsetting these cost decreases was the integration of GLESIA, Davidge and Ubitrade within GL TRADE during 2004, which resulted in €7.0 million in additional IT expenses.

Office, telecom and consultancy

Office, telecom and consultancy expenditure decreased by 2.1% to €84.4 million in 2004, reflecting the impact of the sale of BCC/Clearnet, which more than offset a 6.8% increase in such expenses for Euronext's remaining operations. The increase in expenses was due to advisory costs related to the migration of the Amsterdam derivatives market to LIFFE CONNECT® and new initiatives such as the launch of the Eurodollar contract, which led to a 29% increase in total advisory costs, to €45.0 million. All other costs including travel, telecom and mailing, data and information costs recorded a year-over-year decrease.

Accommodation

Accommodation costs decreased by 3.6% to €51.0 million in 2004, reflecting the sale of BCC/Clearnet, which more than offset a 1.3% increase in costs from Euronext's remaining operations due to growth at GL TRADE. During 2004, Euronext strove to consolidate its facilities and decrease its use of leases.

Marketing

Marketing costs decreased 20.9% to €15.3 million in 2004, reflecting the sale of BCC/Clearnet as well as a 15.2% decrease in marketing costs for Euronext's remaining operations, due to strict cost control over non-mandatory and strategic expenses.

Other expenses

Other expenses decreased by 23.6% to €27.4 million in 2004, reflecting the sale of BCC/Clearnet, which more than offset a 6.3% increase in such costs relating primarily to litigation settlements and an increase in non-recoverable value added tax.

(1): Holding & Unallocated includes central office charges at the group level as well as corporate transaction costs. Revenues for this segment consist of "Other income", as described above.

Euronext's operating profit increased as a percentage of revenues from 21.1% in 2003 to 22.6% in 2004. The increase resulted in part from a decrease in goodwill amortization, which in 2003 had included substantial one-off charges as noted above. In addition, declines in the operating profit margins of the cash trading and sale of software segments were more than offset by improvements in Euronext's other segments. The decline in cash trading margins resulted from a decline in segment revenues due to the factors described above, combined with an increase in the level of segment expenses. The decline in sale of software margins resulted primarily from the costs of integrating MSTS and Glesia.

Net financing income

Net financing income decreased 67.4% to €7.7 million in 2004, resulting from the sale of BCC/Clearnet as well as a 29.0% decrease in net financing income from Euronext's remaining operations, resulting primarily from the revaluation of assets to fair value, which provided €9.9 million in net financing income in 2003, compared to €1.8 million in 2004. This revaluation in turn related primarily to Euronext's equity investment in Atos Origin, which was revalued upward by €8.9 million in 2003, and downward by €0.2 million in 2004.

Impairment of investment

In 2003, an impairment was recognized in the income statement for €47.1 million relating to Euronext's direct shareholding of 2.34% in Euroclear plc. The impairment charge was recorded following a revaluation of the discounted cash flows expected in the new environment created by increased competition in the settlement and custody business in Europe.

Gain (loss) on sale of associates and activities

Euronext recorded a gain of €4.4 million in 2004 relating to the disposal of its remaining interest in Cote Bleue S.A. In 2003, Euronext recorded a net loss of €1.2 million on the voluntary liquidation of various non-consolidated companies.

Gain on disposal of discontinued operations

Euronext recorded a gain of €175 million in 2003 on the sale of its interests in BCC/Clearnet and London Clearing House.

Income from associates

Income from associates increased 37.9% from €2.4 million in 2003 to €3.3 million in 2004, which primarily reflected the full consolidation of NQLX LLC within Euronext's financial statements from

385

July 24, 2003, the date on which Euronext became its sole shareholder. In 2003, Euronext recorded a loss of €6.0 million under this line item in respect of its stake in NQLX LLC. This change was partially offset by a decreased contribution from AtosEuronext SBF, to €1.9 million, compared to €5.8 million in 2003, reflecting restructuring costs incurred in connection with Dutch activities.

Income tax expense

Income tax expense decreased 59.3% to €54.8 million in 2004, reflecting the sale of BCC/Clearnet in 2003, as well as a 30.8% decrease in income tax expense from Euronext's remaining operations. During 2004 the French government enacted legislation through which the capital gains tax was reduced in the years up to 2007. As a result, Euronext's deferred tax positions were adjusted in 2004 to reflect the expected tax rates when the related positions could be liquidated. This resulted in a €27.3 million reduction in income tax expense for 2004.

Minority interests

Minority interests decreased by 28.4% due primarily to the sale of BCC/Clearnet in December 2003 as well as the increase of Euronext's stake in GL TRADE, which more than offset an 8.7% increase in Euronext's minority interests relating to its remaining interests, primarily due to increased net profits of GL TRADE.

Net profit attributable to shareholders of the parent company

For the reasons discussed above, net profit decreased by 29.3% to €149.7 million in 2004.

Liquidity and Capital Resources

Euronext's primary uses of funds are for capital expenditures, working capital, dividend payments, share repurchases under its share repurchase program and repayment or refinancing of debt. Euronext has historically met these requirements through a combination of cash generated by operating activities and short and long term debt. Euronext believes these sources of funds will continue to be adequate to meet its currently anticipated funds requirements.

In addition, in order to expand its business, Euronext may make other strategic acquisitions or enter into business combinations, joint ventures or other strategic partnership arrangements with other companies (including other securities exchanges). Any such transaction (particularly an acquisition or similar business combination) may involve the payment of consideration in the form of cash, shares or other securities, or a combination of both. Euronext has had, and expects to continue to have, discussions with numerous third parties regarding potential strategic alliances. As of the date hereof, Euronext has not entered into any definitive agreement for an acquisition or other business combination, other than as described herein.

Sources of Funds

Euronext's principal sources of liquidity are cash and cash equivalents on hand, short-term financial investments and cash flow from operating activities. At December 31, 2005, Euronext had cash and cash equivalents of €429.5 million and short-term financial instruments of €265.1 million; these amounts were respectively €547.1 million and €162.1 million at June 30, 2006. At June 30, 2006, Euronext did not have any assets classified as held—for—sale. Euronext generated positive cash flows from operating activities of €259.5 million in 2005 and €163.1 million in the six months to June 30, 2006.

Euronext believes that it is well positioned to access the bank lending and capital markets in the event it requires additional financing. Standard & Poor's and Moody's have assigned ratings of "AA" and "Aa2", respectively, to Euronext in July 2005. In 2004, Euronext issued £250 million of 5.125% fixed-rate bonds

386

that mature on June 16, 2009. This issuance refinanced the syndicated bank loan that Euronext had contracted in 2001 to finance its acquisition of LIFFE. In 2006, Euronext obtained a 5-year multi-currency €300.0 million revolving credit facility for general corporate purposes, of which €70.0 million was drawn down on August 10, 2006. In addition, GL TRADE has an amortized bank facility maturing in June 2009 for an outstanding amount of €9 million as of June 30, 2006.

Uses of Funds

Capital Expenditures

Following the completion of the IT migration program and the transfer of LIFFE Market Solutions to AtosEuronext to form AEMS, Euronext's capital expenditures (which primarily related to software and equipment) decreased from €63.5 million in 2004 to €42.7 million in 2005. Capital expenditures in the first half of 2006 amounted to €17.4 million of which €10.3 million relate to software development. For the remainder of 2006, investments either in progress or with respect to which Euronext has made firm commitments amount to approximately €8 million.

Acquisitions

In 2005, Euronext used net cash of €66.8 million on acquisitions, €60.5 million of which related to the acquisition of MTS. The remaining €6.3 million related to the acquisitions of Cscreen and Oasis.

In the first half of 2006, Euronext acquired additional shares of MTS for €12.6 million in cash and CompanyNews Group S.A. for €5.5 million in cash, which purchases were funded using operating cash flows.

Dividends and Share Repurchase Programs

Euronext's has paid dividends in each year since its formation in 2000. In 2005, Euronext paid dividends of €66.4 million. At the annual general meeting held on May 23, 2006, Euronext's shareholders approved an ordinary dividend in respect of 2005 of €1 per share and a share capital repayment of €3 per share, amounting to €446 million in total, that were paid in June and August 2006, respectively.

Euronext used €219.4 million in cash to repurchase its shares in 2004.

Working Capital

Euronext's working capital requirements increased by €25.6 million in 2005, primarily due to an increase in the level of receivables, reflecting higher activity in the fourth quarter of 2005 including listing fees receivable in connection with major IPOs.. At the end of 2005, Euronext had a working capital surplus of €133.7 million, equal to 1.7 months of revenues compared to 2.0 months in 2004. At June 30, 2006, the working capital surplus capital surplus was €123.2 million.

Debt and Minority Put Options

Euronext's financing policy is aimed at financing the growth of its business and ensuring that it is financially flexible while maintaining a strong balance sheet. Euronext's indebtedness structure mainly consists of (i) the June 2009 £250.0 million Bonds issued in 2004 to refinance the LIFFE acquisition indebtedness, (ii) an outstanding €12.0 million bank loan contracted by GL TRADE., and (iii) an August 2006 5-year multi-currency €300.0 million revolving credit facility for general corporate purposes, of which €70.0 million was drawn down on August 10, 2006. None of these loans contain any financial covenants or other provisions that could lead to early redemption, other than customary events of default and change of control provisions. The €300.0 million revolving credit facility permits a change of control of Euronext in certain circumstances (including the proposed combination). The credit agreement also contemplates that following such a change of control, Euronext may undertake certain steps by way of

387

reorganization which will result in an affiliate of Euronext acceding to the credit agreement in place of Euronext. Such accession is subject to the prior consent of the majority lenders, such consent not to be unreasonably withheld or delayed if specified conditions are satisfied. A permitted change of control or reorganization will only trigger a mandatory prepayment if, after the change of control or reorganization, the long-term credit ratings assigned to Euronext by Standard & Poor's and Moody's are, respectively, below A- and below A3 or neither Standard & Poor's nor Moody's assigns a long-term credit rating to Euronext. Debt and other financial liabilities have slightly increased following the currency revaluation of the June 2009 £250.0 million Bonds at a higher sterling / euro rate and the recognition of written put options as described below.

Euronext has granted Borsa Italiana a put option on its 49.0% stake in MBE Holding. The option is exercisable at any time until 2010. As Euronext and Borsa Italiana jointly control MBE Holding, the put option is treated as a derivative financial instrument. The fair value of this option is determined as the difference between the estimated exercise price and 49.0% of the enterprise value determined on the basis of a discounted cash flow method. When the exercise price exceeds the enterprise value, a liability is recognized. At December 31, 2005, the estimated exercise price did not exceed the enterprise value, so no liability was recognized.

Euronext has also granted a put option to GL TRADE founders on up to 10.5% of GL TRADE share capital. The option can be exercised at any moment between February 10, 2006 and June 10, 2024. The exercise price has been set at the average market value of the previous 40 trading days, less 1 euro. The present value of the exercise price of the option (€35.2 million on June 30, 2006) is reflected as a non-current financial liability.

GL TRADE has granted put options to minority shareholders of the companies Glesia and GL TRADE America Inc., which GL TRADE controls. The present value of the exercise price of the options (€4.9 million and €1.0 million respectively) is reflected on the balance sheet as a financial liability under IFRS. Euronext and Borsa Italiana subscribed to 51.0% of the share capital of MTS on November 18, 2005. As a result of the pre-emptive rights and sale mechanism, MBE Holding committed to acquire an additional stake in the controlled MTS of 9.37%. The Euronext share in that commitment at December 31, 2005 (€12.7 million), which was settled in February 2006, was reflected as a financial liability on the balance sheet under IFRS.

At June 30, 2006, the outstanding amount of the bank loan contracted by GL TRADE decreased to €9.0 million following an annual amortization of €3.0 million in June 2006; the present value of the exercise price of the put options granted by GL TRADE to minority shareholders of Glesia and GL TRADE America Inc. amounted to €4.6 million and €1.0 million, respectively, and no liability was recognized regarding the put option granted to Borsa Italiana.

Contractual Obligations

Euronext has various contractual obligations arising from its operations. These obligations are more fully described in this document under various headings under "Management's Discussion and Analysis of Results of Operations and Financial Condition of Euronext" as well as in the notes to Euronext's consolidated financial statements. The following table lists the aggregate maturities of Euronext's long-term debt and operating leases at December 31, 2005:

		Payments Due by Period
Contractual Obligations	Total	Less than 1 years	1 to 3 years	3 to 5 years	After 5 years

Off Balance Sheet Arrangements

In July 2005, GL Trade acquired OASIS for $4 million. The acquisition price may be increased by up to $3 million until June 30, 2007, depending on the income growth recorded by this company.

In June 2006, Euronext, together with Atos Origin, granted an ordinary course unlimited parent guarantee to Atos Euronext Market Solutions in respect of payments related to a building lease in the. UK. Euronext estimates its total exposure under this guarantee at £11.5 million.

Critical Accounting Policies

In preparing its financial statements, Euronext makes estimates concerning a variety of matters. Some of these matters are highly uncertain, and Euronext's estimates involve judgments it makes based on the information available to it. The following discussion highlights Euronext's critical accounting policies and estimates. Euronext considers an accounting policy or estimate to be critical if it involves significant judgments and estimates on the part of Euronext's management and changes to those judgments or estimates could have a material impact on Euronext's financial presentation. The discussion below addresses only those estimates that Euronext considers most important based on the degree of uncertainty and the likelihood of a material impact if a different estimate were used. There are other areas in which Euronext uses estimates about uncertain matters, but for which the reasonably likely effect of changed or different estimates is not material to Euronext's financial presentation. For a summary of all of Euronext's significant accounting policies, see Note 1 to Euronext's consolidated financial statements.

Pension Plan Assumptions

Euronext recognizes its net obligation in respect of its defined benefit pension plans on the basis of an actuarial estimate of the future benefit that employees have earned as of the balance sheet date, net of the valuation of assets to meet these obligations. Euronext prepares this estimate on an annual basis taking into account different actuarial assumptions. Two critical assumptions used are the discount rate (equal to the yield at the balance sheet date on high quality fixed income instruments) on future benefits and the expected return on plan assets. Euronext evaluates these critical assumptions at least annually on a plan-specific and country-specific basis. Other assumptions relate to demographic factors, such as retirement age, life expectancy and staff turnover, which are periodically evaluated and updated to reflect Euronext's past experience and future expectations. Depending on the assumptions and estimates used, Euronext's pension benefit expense could vary within a range of outcomes and have a material effect on reported earnings.

Impairment testing

Rather than being amortized, goodwill is tested for impairment at least annually under IFRS, or more frequently when there is an indication of an impairment loss. Goodwill is tested at the level of cash-generating units, which correspond to Euronext businesses that generate independent cash flows. The impairment test is based on the relationship between the carrying amount of an asset and its recoverable

389

amount, which is the higher of its sale price or value in use. Value in use is in turn based on the discounted future cash flows method. The determination of the underlying assumptions related to the recoverability of intangible assets is subjective, and therefore requires the exercise of considerable judgment by Euronext. Although Euronext performs sensitivity analyses on its main assumptions in order to strengthen the reliability of its impairment tests, changes in key assumptions about Euronext's business and prospects, or changes in market conditions, could result in future impairment charges.

Valuation of Available for Sale securities

Investments in Available for Sale securities are carried at fair value. The determination of such fair values is performed either by reference to quoted market prices when these are available or by using a valuation technique. Valuation techniques may encompass elements of discounted cash flow analysis, and therefore require the exercise of judgment by Euronext. Although Euronext performs sensitivity analyses on its main assumptions in order to strengthen the reliability of its calculations, changes in key assumptions could result in different fair values.

Share-based payments

In accordance with IFRS 2, the grant of stock options to employees for services rendered represents a supplementary benefit provided by Euronext. Under IFRS 2, Euronext estimates the fair value of these stock options at the grant date and records the value within shareholders' equity. Fair value is determined using a Black and Scholes option pricing model that takes into account the specific features of the stock option plan (net price, period of exercise, etc.), market data at the grant date (such as price, volatility, etc.) and behavioral assumptions relating to option holders. Different assumptions could result in material changes to the expense amounts recorded for these options.

Contingent liabilities

Euronext is involved in legal and arbitration proceedings in the ordinary course of its business. Euronext accrues a liability in its financial statements when an adverse outcome is probable and the amount of the loss can be reasonably estimated. Due to the uncertainty inherent in such matters, it is often difficult to predict the final outcome. The cases and claims against Euronext often raise difficult and complex issues. In determining whether a loss should be accrued Euronext evaluates, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Assessing these matters inherently involves the exercise of significant management judgment. Changes in these factors or outcomes that are different from those Euronext expects to occur could materially impact Euronext's financial position or its results of operations.

Quantitative and Qualitative Disclosures About Market Risk

General

As a result of its operating and financing activities, Euronext is exposed to market risks such as changes in interest rates and currency exchange rates, as well as equity market risks. Euronext has implemented policies and procedures to measure, manage, monitor and report risk exposures within the group, which are regularly reviewed by the appropriate management and supervisory bodies (Risk Committee, Managing Board or Audit Committee, as appropriate).

Euronext's treasury and financing department is charged with identifying risk exposures and monitoring and managing such risks on a daily basis. Euronext's subsidiaries centralize their cash investments, report their risks and hedge their exposures with the group's central treasury and financing department as necessary in accordance with local law.

390

Euronext uses derivative instruments solely to hedge financial risks related to its financial positions or risks that are otherwise incurred in the normal course of its commercial activities. It does not use derivative instruments for speculative or trading purposes. Euronext's principal derivative instrument at December 31, 2005 was a fixed-to-floating rate swap entered into to hedge its fixed rate bonds issued in 2004.

The following table summarizes the composition of Euronext's financial assets and liabilities at December 31, 2005.

Interest Rate Risk

Substantially all of Euronext's financial assets and liabilities are based on floating rates or on fixed rates that have been swapped to floating rates via fixed to floating rate swaps. As part of its hedging activities, Euronext enters into over-the-counter interest rate derivative instruments, such as swaps, with counterparties that meet minimum creditworthiness and rating standards. As reflected in the table above, Euronext has entered into a fixed-to-floating rate swap to hedge a £250 million fixed rate bond issuance denominated in sterling.

Because Euronext is a net lender at floating rate in euros, when interest rates on euro-denominated instruments decrease, Euronext's financing income is negatively impacted. Assuming constant levels of euro-denominated net financial assets at floating rate or at fixed rate with a maturity of less than one year, Euronext's annual financing income would decrease by €3.8 million for each 1% decrease in euro interest

391

rates based on positions at December 31, 2005 (€3.2 million for each 1% decrease in euro interest rates based on positions at June 30, 2006).

Similarly, because Euronext is a net borrower at floating rate in sterling, when interest rates on sterling-denominated instruments increase, Euronext's financing expenses increase. Assuming constant levels of sterling-denominated net financial liabilities at floating rate or at fixed rate with a maturity of less than one year, Euronext's annual financing expense would increase by €0.9 million for each 1% increase in sterling interest rates based on positions at December 31, 2005 (€0.5 million for each 1% increase in sterling interest rates based on positions at June 30, 2006).

Currency risk

As a result of Euronext's acquisition of LIFFE, a significant part of Euronext's assets, liabilities, income and expenses of Euronext is recorded in pound sterling, exposing Euronext to a currency risk. When the euro increases in value against the pound sterling, for example, revenues denominated in pound sterling generate a reduced contribution to Euronext's consolidated revenues when translated into euros. Similarly, when the euro decreases in value against the pound sterling, the impact of expenses denominated in pounds sterling is greater when translated into euros. In 2005, 32.5% of Euronext's revenues and 30.3% of its expenses were denominated in pounds sterling.

At December 31, 2005, Euronext's net currency position was £284 million, consisting of £579 million in assets (including £291 million of goodwill and £164 million of cash, cash equivalents and short term financial investments) and £295 million in liabilities. The borrowings in pounds sterling, for an amount of £254 million, constitute a partial hedge of the net assets in pounds sterling. Currency exchange rate differences had a positive impact of €12.5 million on the group's consolidated equity in 2005. At December 31, 2005, based on the £284 million net currency position of the group, a hypothetical 10% increase in the euro/sterling exchange rate would have had a negative €37.7 million impact on shareholders equity.

On June 30, 2006, the Group's net currency position was £ 317 million, consisting of £ 624 million in assets (including £ 288 million goodwill) and £ 307 million in liabilities. The borrowings in pounds sterling, for an amount of £ 254 million, constitute a partial hedge of the net assets in pounds sterling. The currency exchange rate differences had a positive impact of €4.9 million on the Group's consolidated equity at June 30, 2006. At June 30, 2006, based on the £317 million net currency position of the group, a hypothetical 10% increase in the euro/sterling exchange rate would have had a negative €41.7 million impact on shareholders' equity.

Equity market risk

Euronext is exposed to equity market risk through its investment in shares of Atos Origin S.A., which were valued at €18.1 million as of December 31, 2005 (€16.6 million as of June 30, 2006). A decrease in the value of Atos Origin shares could lead to a financial loss for Euronext. This position is monitored and reported to senior management on a daily basis. At December 31, 2005, all else being equal, a hypothetical 10% decline in the market price of the shares of Atos Origin would have had a €1.8 million impact on the fair value of Euronext's investment in Atos Origin (€1.7 million based on the position at June 30, 2006).

Until the end of 2005, variations in the fair value of these shares were recorded in financing income (revaluation of asset at fair value through profit and loss) under IFRS and in equity (other comprehensive income) under U.S. GAAP. Following an amendment to IAS 39 that took effect on January 1, 2006 which limits the possibility of designating a financial asset or liability as one at fair value through profit and loss upon initial recognition, Euronext's equity investment in Atos Origin has been reclassified as an available-for-sale asset. Accordingly, variations in the fair value of these shares are now recognized in equity.

Summary of Material Differences between IFRS and U.S. GAAP

Euronext prepares its consolidated financial statements in accordance with IFRS as adopted by the European Union, which differ in certain significant respects from U.S. GAAP. The principal differences between IFRS and U.S. GAAP as they relate to Euronext are discussed in Note 3.14 to Euronext's consolidated financial statements as of and for the years ended December 31, 2005, 2004 and 2003 and in Note 11 to Euronext's unaudited interim condensed consolidated financial statements as of June 30, 2006 and for the six-month period ended June 30, 2006 and 2005. These notes include a reconciliation of net income and shareholders' equity under IFRS to net income and shareholders' equity under U.S. GAAP. The most significant items in reconciling Euronext's net income and shareholders' equity under IFRS and U.S. GAAP related to impairment and amortization of goodwill and intangible assets, recognition of admission fees and sale of software revenues, accounting for derivatives and hedging instruments, deferred tax related to business combinations and employee benefits and stock-based compensation. Further information on such differences and adjustments is set forth in the notes to Euronext's consolidated financial statements mentioned above.

Net income under U.S. GAAP amounted to €221.1 million for the year ended December 31, 2005, up from €173.9 million in 2004. This corresponds to a 27% increase in net income under U.S. GAAP, as compared to a 61% increase in net income under IFRS. This difference in trend is primarily related to the amortization of goodwill and intangible assets induced by previous business combinations. In 2004, the impact of differences generated by previous business combinations on net income under U.S. GAAP was €25.9 million higher than under IFRS, since goodwill continued to be amortized under IFRS (though not under U.S. GAAP). In 2005, the end of goodwill amortization under IFRS combined with the recording of amortization expenses under U.S. GAAP related to intangible assets had a negative €1.8 million effect from IFRS to U.S. GAAP.

Net income under U.S. GAAP amounted to €169.7 million for the six months ended June 30, 2006, compared with a €100.6 million for the six months ended June 30, 2005.

Each holder of NYSE Euronext common stock is entitled to one vote per share. Subject to the rights, if any, of the holders of any series of preferred stock if and when issued and subject to applicable law, all voting rights are vested in the holders of shares of NYSE Euronext common stock.

In the event of a voluntary or involuntary liquidation, dissolution or winding up of NYSE Euronext, the holders of NYSE Euronext common stock will be entitled to share equally in any of the assets available for distribution after NYSE Euronext has paid in full all of its debts and after the holders of all outstanding series of NYSE Euronext preferred stock, if any, have received their liquidation preferences in full.

Ownership and Voting Limits on NYSE Euronext Capital Stock

The NYSE Euronext certificate of incorporation will place certain ownership and voting limits on the holders of its capital stock. Specifically, under the NYSE Euronext certificate of incorporation:

•: any "affiliate" (as such term is defined in Rule 12b-2 under the Exchange Act) of such person;
•: any other person(s) with which such first person has any agreement, arrangement or understanding (whether or not in writing) to act together for the purpose of acquiring, voting, holding or disposing of shares of the stock of NYSE Euronext;

394

•: in the case of a person that is a company, corporation or similar entity, any executive officer (as defined under Rule 3b-7 under the Exchange Act) or director of such person and, in the case of a person that is a partnership or a limited liability company, any general partner, managing member or manager of such person, as applicable;
•: in the case of a person that is a "member organization" (as defined in the rules of the NYSE, as such rules may be in effect from time to time), any "member" (as defined in the rules of the NYSE, as such rules may be in effect from time to time) that is associated with such person (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act);
•: in the case of a person that is an OTP Firm (as defined in the rules of NYSE Arca, Inc., as such rules may be in effect from time to time), any OTP Holder (as defined in the rules of NYSE Arca, Inc., as such rules may be in effect from time to time) that is associated with such person (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act);
•: in the case of a person that is a natural person, any relative or spouse of such natural person, or any relative of such spouse who has the same home as such natural person or who is a director or officer of NYSE Euronext or any of its parents or subsidiaries;
•: in the case of a person that is an executive officer (as defined under Rule 3b-7 under the Exchange Act), or a director of a company, corporation or similar entity, such company, corporation or entity, as applicable;
•: in the case of a person that is a general partner, managing member or manager of a partnership or limited liability company, such partnership or limited liability company, as applicable;
•: in the case of a person that is a "member" (as defined in the rules of the NYSE, as such rules may be in effect from time to time), the "member organization" (as defined in the rules of the NYSE, as such rules may be in effect from time to time) with which such person is associated (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act); and
•: in the case of a person that is an OTP Holder, the OTP Firm with which such person is associated (as determined using the definition of "person associated with a member" as defined under Section 3(a)(21) of the Exchange Act).

In the event that a person, either alone or together with its related persons, beneficially owns shares of stock of NYSE Euronext representing more than 20% of the total number of votes entitled to be cast on any matter, such person and its related persons shall be obligated to sell promptly, and NYSE Euronext shall be obligated to purchase promptly, at a price equal to the par value of such shares of stock and to the extent that funds are legally available for such purchase, that number of shares of stock of the NYSE Euronext necessary so that such person, together with its related persons, shall beneficially own shares of stock of NYSE Euronext representing in the aggregate no more than 20% of the total number of votes entitled to be cast on any matter, after taking into account that such repurchased shares shall become treasury shares and shall no longer be deemed to be outstanding.

In the event that a person, either alone or together with its related persons, possesses more than 10% of the total number of votes entitled to be cast on any matter (including if it possesses this voting power by virtue of agreements entered into by other persons not to vote shares of NYSE Euronext's capital stock), then such person, either alone or together with its related persons, will not be entitled to vote or cause the voting of these shares of NYSE Euronext capital stock to the extent that such shares represent in the aggregate more than 10% of the total number of votes entitled to be cast on any matter, and NYSE Euronext shall disregard any such votes purported to be cast in excess of this percentage.

395

The NYSE Euronext board of directors may waive the provisions regarding ownership and voting limits by a resolution expressly permitting this ownership or voting (which resolution must be filed with and approved by the SEC and all required European regulators prior to being effective), subject to a determination of the board that:

•: the acquisition will not impair the ability of NYSE Euronext's regulated subsidiaries to discharge their respective responsibilities under the Exchange Act and the rules and regulations under the Exchange Act and is otherwise in the best interests of NYSE Euronext and its stockholders and its regulated subsidiaries;
•: the acquisition will not impair the SEC's ability to enforce the Exchange Act or any European regulator's ability to enforce the European Exchange Act;
•: neither the person obtaining the waiver nor any of its related persons is subject to any statutory disqualification (as defined in Section 3(a)(39) of the Exchange Act) if such person is seeking to obtain a waiver above the 20% level;
•: for so long as NYSE Euronext directly or indirectly controls NYSE Arca, Inc., NYSE Arca Equities, Inc., or any facility of the NYSE Arca, Inc., neither the person obtaining the waiver nor any of its related persons is an ETP holder, an OTP holder or an OTP firm if such person is seeking to obtain a waiver above the 20% level; and
•: for so long as NYSE Euronext directly or indirectly controls New York Stock Exchange LLC or NYSE Market, neither the person obtaining the waiver nor any of its related persons is a member or member organization of the New York Stock Exchange LLC if such person is seeking to obtain a waiver above the 20% level.

In making these determinations, the NYSE Euronext board of directors may impose conditions and restrictions on the relevant stockholder or its related persons that it deems necessary, appropriate or desirable in furtherance of the objectives of the Exchange Act, the European Exchange Act and the governance of NYSE Euronext.

These provisions of the NYSE Euronext certificate of incorporation could delay or deter a change of control of NYSE Euronext, which could adversely affect the price of NYSE Euronext common stock.

The NYSE Euronext certificate of incorporation also provides that the NYSE Euronext board of directors has the right to require any person and its related persons that the NYSE Euronext board of directors reasonably believes to be subject to the voting or ownership restrictions summarized above, and any stockholder (including related persons) that at any time beneficially owns 5% or more of NYSE Euronext's outstanding capital stock, to provide to NYSE Euronext, upon the board's request, complete information as to all shares of capital stock of NYSE Euronext that such stockholder beneficially owns, as well as any other information relating to the applicability to such stockholder of the voting and ownership requirements outlined above.

Transfer Restrictions on Certain Shares of NYSE Euronext Common Stock

NYSE Euronext's certificate of incorporation imposes transfer restrictions on the shares of its common stock that were issued in the merger of the NYSE and Archipelago in respect of the former NYSE memberships. These transfer restrictions are scheduled to be removed in three equal installments on the first, second and third anniversaries of the merger, which occurred on March 7, 2006. Prior to the removal of the transfer restrictions from any such share, neither any record owner nor any beneficial owner of such share may, directly or indirectly, assign, sell, transfer or otherwise dispose of such share, except

396

pursuant to one of the following limited exceptions set forth in NYSE Euronext's certificate of incorporation:

•

if the owner of such share is an entity (including a corporation, partnership, limited liability company or limited liability partnership), such owner may transfer the share to:

•: any person of which such owner directly or indirectly owns all of the common voting and equity interest;
•: any other entity if a person directly or indirectly owns all of the common voting and equity interest of both such owner and such other entity;
•: any person that directly owns all of the common voting and equity interest of such owner;
•: the equity holders of such owner upon a bona fide liquidation or dissolution of such owner; or
•: a trustee of the bankruptcy estate of such owner if such owner has become bankrupt or insolvent;

•

if the owner of such share is a natural person, such owner may transfer the share to:

•: any family member of such owner (including such owner's spouse, domestic partner, children, stepchildren, grandchildren, parents, parents-in-law, grandparents, brothers, sisters, uncles, aunts, cousins, nephews and nieces);
•: any trust or foundation solely for the benefit of such owner and /or such owner's family members (which is referred to as a "qualified trust"); or
•: a trustee of the bankruptcy estate of such owner if such owner has become bankrupt or insolvent;
•: the owner may pledge or hypothecate, or grant a security interest in, such share, and may transfer such share as a result of any bona fide foreclosure resulting therefrom;
•: if the owner is a qualified trust, the owner may transfer the share to any beneficiary of such qualified trust (including a trust for the benefit of such beneficiary) or transfer the share in exchange for cash necessary to pay taxes, debts or other obligations payable by reason of the death of the grantor of such qualified trust or any one or more of such beneficiaries, in each case in accordance with the terms of the trust instrument, and;
•: if the owner is a fiduciary of the estate of a deceased person, and is holding such share on behalf of such estate, such owner may transfer such share to the beneficiaries of such estate or in exchange for cash necessary to pay taxes, debts or other obligations payable by reason of the death of the deceased person.

In addition, if all of the beneficial owners of a share of NYSE Euronext common stock die, the transfer restrictions will automatically be removed from such share.

NYSE Euronext's certificate of incorporation sets forth two additional rules with respect to the transfers described in the previous paragraph. First, any shares that are transferred pursuant to the bulleted exceptions in the prior paragraph will remain subject to the transfer restrictions and other terms of NYSE Euronext's certificate of incorporation. Second, any beneficial owner of shares of NYSE Euronext common stock who makes a transfer pursuant to the bulleted exceptions in the prior paragraph must transfer shares of common stock that expire on the first, second and third year anniversary of the completion of the merger in the same proportion as the beneficial owner held such shares prior to the transfer. As a result, the proportion of a beneficial owner's shares of common stock that are subject to transfer restrictions expiring on the first, second and third anniversary of the completion of the merger will be the same after any of the transfers described in the previous paragraph as it was before such transfer.

397

In addition, each of (1) General Atlantic Partners 77, L.P., GAP-W Holdings, L.P., GapStar LLC, GAP Coinvestment Partners II, L.P., and GAPCO GMBH & CO. KG, (2) GS Archipelago Investment, L.L.C., SLK-Hull Derivatives LLC and Goldman Sachs Execution and Clearing, L.P. (which are referred to collectively as the "Goldman Sachs Affiliates"), and (3) GSP, LLC, an entity in which Gerald D. Putnam, NYSE Group, has a controlling interest, have entered into separate support and lock-up agreements, pursuant to which they have agreed not to transfer their shares of NYSE Group common stock that they received in the NYSE-Archipelago merger for a certain period of time. This transfer restriction will apply equally to shares of NYSE Euronext common stock received in the merger by holders of these restricted shares. The transfer restrictions applicable to General Atlantic and the Goldman Sachs Affiliates are scheduled to expire in three equal installments on the first, second and third anniversaries of the merger. The transfer restrictions applicable to GSP, LLC are scheduled to expire on the first anniversary of the merger.

NYSE Euronext's board of directors may, in its discretion, remove the transfer restrictions applicable to any number of NYSE Euronext common stock on terms and conditions and in ratios and numbers that it may fix in its sole discretion. However, if any transfer restrictions are removed from shares of NYSE Euronext common stock held by General Atlantic, the Goldman Sachs Affiliates or GSP that are subject to lock-up agreements with NYSE Group, the same transfer restrictions will be removed from an equivalent percentage of all other shares of NYSE Euronext common stock that are otherwise subject to the transfer restrictions, including shares of NYSE Euronext common stock held by the former NYSE members.

NYSE Euronext's board of directors intends that, as market conditions permit, it will provide holders of the Year 1 Shares, Year 2 Shares and/or Year 3 Shares with opportunities, from time to time, to sell these shares pursuant to additional registered offerings. NYSE Euronext's board of directors will remove the transfer restrictions from the shares of NYSE Euronext common stock that are sold in these offerings. NYSE Euronext's board of directors expects to determine whether to conduct any future offerings, the number of such offerings (if any), the maximum number of shares of NYSE Euronext common stock eligible to be sold in any offering, and the timing of these offerings based upon its view at the time of the market's ability to absorb the newly unrestricted shares to be sold in the offering without an adverse impact on the market price of shares of NYSE Euronext common stock. However, the future sale of the Year 1 Shares, Year 2 Shares and Year 3 Shares could adversely affect the prevailing market price of NYSE Euronext common stock and its ability to raise equity capital in the future.

The following table sets out the timetable for the automatic expiration of the transfer restrictions applicable to the shares described above (including the shares of the General Atlantic Entities, Goldman Sachs Affiliates and GSP).

Date of Currently Scheduled Removal of Transfer Restrictions		Number of Shares for Which Transfer Restrictions Will Be Removed
March 7, 2007		22,558,925
March 7, 2008		33,943,089
March 7, 2009		41,771,830
Total		98,273,844

U.S. Federal Income Tax Considerations for Non-U.S. Holders of NYSE Euronext Common Stock

The following is a general discussion of material U.S. federal income and estate tax considerations with respect to the ownership and disposition of NYSE Euronext common stock applicable to non-U.S. holders. This discussion is based on current provisions of the Internal Revenue Code of 1986, as amended, existing and proposed U.S. Treasury regulations thereunder, and administrative rulings and court decisions in effect as of the date hereof, all of which are subject to change at any time, possibly with retroactive effect.

398

For the purposes of this discussion, the term "non-U.S. holder" means a beneficial owner of NYSE Euronext common stock other than:

•: a citizen or resident of the United States;
•: a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in the United States or under the laws of the United States or of any state;
•: an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or
•: a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (2) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a domestic trust.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds shares of NYSE Euronext common stock, the tax treatment of a person treated as a partner generally will depend on the status of the partner and the activities of the partnership. Persons that for U.S. federal income tax purposes are treated as a partner in a partnership holding shares of NYSE Euronext common stock should consult their tax advisors.

It is assumed in this discussion that a non-U.S. holder holds shares of NYSE Euronext common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxation that may be important to a non-U.S. holder in light of that non-U.S. holder's particular circumstances or that may be applicable to holders subject to special treatment under U.S. federal income tax law (including, for example, financial institutions, dealers in securities, traders in securities that elect mark-to-market treatment, insurance companies, tax-exempt entities, holders who acquired NYSE Euronext common stock pursuant to the exercise of employee stock options or otherwise as compensation, entities or arrangements treated as partnerships for U.S. federal income tax purposes, holders liable for the alternative minimum tax, and holders who hold their NYSE Euronext common stock as part of a hedge, straddle, constructive sale or conversion transaction). In addition, except to the extent provided below, this discussion does not address U.S. federal tax laws other than those pertaining to the U.S. federal income tax, nor does it address any aspects of U.S. state, local or non-U.S. taxes. Accordingly, prospective investors are urged to consult with their own tax advisors regarding the U.S. federal, state, local, non-U.S. income and other tax considerations of acquiring, holding and disposing of shares of NYSE Euronext common stock.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE OWNERSHIP AND DISPOSITION OF NYSE EURONEXT COMMON STOCK. HOLDERS OF NYSE EURONEXT COMMON STOCK ARE URGED TO CONSULT WITH THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL, NON-U.S. INCOME AND OTHER TAX LAWS) OF THE OWNERSHIP AND DISPOSITION OF NYSE EURONEXT COMMON STOCK.

Dividends

In general, dividends, if any, paid by NYSE Euronext to a non-U.S. holder will be subject to U.S. withholding tax at a rate of 30% of the gross amount (or a reduced rate prescribed by an applicable income tax treaty) unless the dividends are effectively connected with a trade or business carried on by the non-U.S. holder within the United States and, if an income tax treaty applies, are attributable to a permanent establishment of the non-U.S. holder within the United States. Dividends effectively connected with this U.S. trade or business, and, if an income tax treaty applies, attributable to such a permanent establishment of a non-U.S. holder, generally will not be subject to U.S. withholding tax if the non-U.S.

399

holder files certain forms, including Internal Revenue Service Form W-8ECI (or any successor form), with the payor of the dividend, and generally will be subject to U.S. federal income tax on a net income basis, in the same manner as if the non-U.S. holder were a resident of the United States. A non-U.S. holder that is a corporation may be subject to an additional "branch profits tax" at a rate of 30% (or a reduced rate as may be specified by an applicable income tax treaty) on the repatriation from the United States of its "effectively connected earnings and profits," subject to certain adjustments. Under applicable U.S. Treasury regulations, a non-U.S. holder (including, in certain cases of non-U.S. holders that are entities, the owner or owners of these entities) is required to satisfy certain certification requirements in order to claim a reduced rate of withholding pursuant to an applicable income tax treaty.

Gain on Sale or Other Disposition of NYSE Euronext Common Stock

In general, a non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of the holder's NYSE Euronext common stock unless:

•: the gain is effectively connected with a trade or business carried on by the non-U.S. holder within the United States (in which case the branch profits tax discussed above may also apply if the non-U.S. holder is a corporation) and, if required by an applicable income tax treaty as a condition to subjecting a non U.S. holder to U.S. federal income tax on a net basis, the gain is attributable to a permanent establishment of the non-U.S. holder maintained in the United States;
•: the non-U.S. holder is an individual and is present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are satisfied; or
•: NYSE Euronext is or has been a U.S. real property holding corporation (a "USRPHC") for U.S. federal income tax purposes (which NYSE Euronext does not believe that it has been, currently is, or will become) at any time within the shorter of the five-year period preceding the disposition and the non-U.S. holder's holding period. If NYSE Euronext were or were to become a USRPHC at any time during this period, generally gains realized upon a disposition of shares of NYSE Euronext common stock by a non-U.S. holder that did not directly or indirectly own more than 5% of NYSE Euronext common stock during this period would not be subject to U.S. federal income tax, provided that NYSE Euronext common stock is "regularly traded on an established securities market" (within the meaning of Section 897(c)(3) of the Internal Revenue Code). NYSE Euronext believes that its common stock will be treated as regularly traded on an established securities market during any period in which it is listed on the NYSE.

U.S. Federal Estate Tax

NYSE Euronext common stock owned or treated as owned by an individual who is not a citizen or resident (as defined for U.S. federal estate tax purposes) of the United States at the time of death will be includible in the individual's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise, and therefore may be subject to U.S. federal estate tax.

Backup Withholding, Information Reporting and Other Reporting Requirements

Generally, NYSE Euronext must report annually to the Internal Revenue Service and to each non-U.S. holder the amount of dividends paid to, and the tax withheld with respect to, each non-U.S. holder. These reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable tax treaty. Copies of this information also may be made available under the provisions of a specific treaty or agreement with the tax authorities in the country in which the non-U.S. holder resides or is established.

U.S. backup withholding tax (currently at a rate of 28%) is imposed on certain payments to persons that fail to furnish the information required under the U.S. information reporting requirements. Dividends

400

paid to a non-U.S. holder of NYSE Euronext common stock generally will be exempt from backup withholding if the non-U.S. holder provides a properly executed IRS Form W-8BEN or otherwise establishes an exemption.

Under U.S. Treasury regulations, the payment of proceeds from the disposition of NYSE Euronext common stock by a non-U.S. holder effected at a U.S. office of a broker generally will be subject to information reporting and backup withholding, unless the beneficial owner, under penalties of perjury, certifies, among other things, its status as a non-U.S. holder or otherwise establishes an exemption. The payment of proceeds from the disposition of NYSE Euronext common stock by a non-U.S. holder effected at a non-U.S. office of a broker generally will not be subject to backup withholding and information reporting, except as noted below. In the case of proceeds from a disposition of NYSE Euronext common stock by a non-U.S. holder effected at a non-U.S. office of a broker that is:

•: a U.S. person;
•: a "controlled foreign corporation" for U.S. federal income tax purposes;
•: a foreign person 50% or more of whose gross income from certain periods is effectively connected with a U.S. trade or business; or
•: a foreign partnership if at any time during its tax year (a) one or more of its partners are U.S. persons who, in the aggregate, hold more than 50% of the income or capital interests of the partnership or (b) the foreign partnership is engaged in a U.S. trade or business;

information reporting will apply unless the broker has documentary evidence in its files that the owner is a non-U.S. holder and certain other conditions are satisfied, or the beneficial owner otherwise establishes an exemption (and the broker has no knowledge or reason to know to the contrary). Backup withholding will apply if the sale is subject to information reporting and the broker has actual knowledge that you are a United States person.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can be refunded or credited against the non-U.S. holder's U.S. federal income tax liability, if any, provided that the required information is furnished to the Internal Revenue Service in a timely manner.

COMPARISON OF SHAREHOLDER RIGHTS PRIOR TO AND AFTER THE COMBINATION

This section describes the material differences between the rights of holders of NYSE Group common stock and holders of Euronext shares before the combination, on the one hand, and the rights of holders of NYSE Euronext common stock after the combination, on the other hand. Because both NYSE Group and NYSE Euronext are Delaware corporations, the differences between the rights of holders of NYSE Group common stock prior to the combination and the rights of holders of NYSE Euronext common stock after the combination primarily result from the differences between the governing documents of NYSE Group and NYSE Euronext.

This section does not include a complete description of all differences between the rights of these respective shareholders, nor does it include a complete description of their specific rights. Furthermore, the identification of some of the differences of these rights as material is not intended to indicate that other differences that may be equally important do not exist. All NYSE Group stockholders and Euronext shareholders are urged to carefully read the relevant provisions of the Delaware General Corporation Law, the Dutch Civil Code (Burgerlijk Wetboek), the NYSE Group certificate of incorporation and bylaws, the Euronext articles of association and the form of NYSE Euronext certificate of incorporation and bylaws that will be in effect upon completion of the combination (which forms are included as Exhibits 3.1 and 3.2, respectively, to the registration statement of which this document forms a part).

In considering the terms of the NYSE Euronext certificate of incorporation and bylaws, NYSE Group and Euronext considered the unique role to be played by NYSE Euronext and its subsidiaries as operators of regulated markets in the United States and Europe and, in the case of NYSE Group, as the parent company of U.S. self-regulatory organizations and the independence and public interest criteria embodied in its director selection criteria, as well as pronouncements from the SEC and the European regulators, including the SEC's proposed Regulation SRO.

Copies of the NYSE Group certificate of incorporation and bylaws and the Euronext articles of association are available to NYSE Group stockholders and Euronext shareholders, respectively, upon request. See "Where You Can Find More Information." You are encouraged to obtain and read these documents.

Dividends/Distributions
Holders of NYSE Group common stock are entitled to receive dividends when, as and if declared by the NYSE Group board of directors out of funds legally available for payment, subject to the rights of holders, if any, of NYSE Group preferred stock. Holders of NYSE Group common stock are entitled to share pro rata in the assets of NYSE Group upon dissolution after provision has been made for all claims against, and obligations of, NYSE Group.	Distributions to Euronext's shareholders are permitted only if and to the extent that, following the distribution, Euronext's unconsolidated shareholders' equity (eigen vermogen) remains greater than or equal to the sum of paid-in (and called) share capital and (non-consolidated) undistributable reserves (which Dutch law requires Euronext to maintain). Subject to approval of the Euronext supervisory board, the Euronext managing board may propose that distributable profits shall be retained or distributed to Euronext shareholders. At Euronext's annual general meeting of shareholders (or at an extraordinary meeting of shareholders), the shareholders approve or reject the Euronext managing board's proposal. For calculation of the profits available for distribution, shares held by Euronext in its own capital shall not count.	Same as for NYSE Group.
	Subject to the approval of the Euronext supervisory board, the Euronext managing board can distribute an interim dividend to shareholders, provided Euronext has distributable profits in accordance with the requirements described above. To evidence the availability of distributable profits, the Euronext managing board must prepare an interim statement of assets and liabilities.

403

	Subject to the approval of the Euronext supervisory board and the general meeting of shareholders, the Euronext managing board may determine that the distribution shall not be in cash but in the form of a stock dividend or an option to receive cash or a stock dividend.
Annual Meeting of Shareholders
Under the Delaware General Corporation Law, an annual meeting of shareholders must be held for the election of directors on a date and at a time designated by or in the manner provided in the corporation's bylaws. Any other proper business may be transacted at the annual meeting. Under the NYSE Group bylaws, annual meetings of shareholders are held for the election of directors at any date, time and place as may be designated by the NYSE Group board of directors from time to time. Under the NYSE Group bylaws, notice of the place, day and hour of the meeting and the general nature of the business to be considered must be provided to each shareholder not less than 10 days and not more than 60 days before the meeting date.	Under Dutch law, the annual general meeting should be held no later than six months after the end of the fiscal year. Pursuant to the Euronext articles of association, general meetings of shareholders are held in Amsterdam, the Netherlands. Under the Euronext articles of association, the notice convening a general meeting of shareholders must be given no later than the 15th day prior to the day of the meeting. The notice must be accompanied by the agenda for the meeting or must state that the agenda can be obtained at the offices of Euronext. Unless a resolution is passed unanimously at a meeting in which the entire issued capital is represented, no valid resolutions can be adopted at a general meeting of shareholders in respect of items that are not included on the agenda in the notice convening the meeting or which have not been published in the same manner with due observance of the period set for giving notice of the meeting. See also "Comparison of Shareholder Rights Prior to and After the Combination—Shareholder Proposals" below.	Same as for NYSE Group.

404

Special Meeting of Shareholders
Special meetings of stockholders may be called at any time by, and only by, the chairman of the board of directors, the chief executive officer or by resolution of a majority of the NYSE Group board of directors.	Extraordinary general meetings of shareholders may be held whenever the managing board or the supervisory board of Euronext deems it desirable. In addition, Euronext shareholders representing at least one-tenth of the outstanding share capital of Euronext may request the Euronext managing board and the supervisory board to convene an extraordinary general meeting of shareholders. If neither of these boards takes appropriate action to hold such meeting within a period of six weeks after the request is made, such shareholder can address a court to be authorized to convene an extraordinary meeting.	Special meetings of stockholders may be called at any time by, and only by, the chairman of the board, of directors, the deputy chairman of the board of directors, the chief executive officer, the deputy chief executive officer or by resolution of a majority of the NYSE Euronext board of directors.
Voting Rights—General
Each outstanding share of NYSE Group common stock entitles its holder to one vote per share. Shares of NYSE Group common stock held by NYSE Group are counted as treasury shares and are therefore not treated as outstanding. Subject to the rights, if any, of the holders of any series of preferred stock outstanding and subject to applicable law, all voting rights are vested in the holders of shares of NYSE Group common stock. There are no cumulative voting rights. There are certain limitations on voting if a person (either alone or together with their related persons) owns above a certain	Each outstanding Euronext share entitles its holder to one vote. However, Euronext may not exercise the voting rights for any Euronext shares held by it or any of its subsidiaries at any meeting of shareholders. All shareholder resolutions are adopted by an absolute majority of the votes cast, unless the Euronext articles of association or Dutch law prescribe otherwise. The validity of shareholder decisions is not dependent on a quorum, unless Dutch law or the Euronext articles of association provide otherwise. The Euronext articles of association and/or Dutch law require, under certain circumstances, a qualified	Same as for NYSE Group.

In addition, pursuant to the Euronext articles of association and Dutch law, decisions of the Euronext managing board involving a significant change in the identity or character of Euronext are subject to the approval of the general meeting of shareholders. Such decisions include:			equity securities where the consideration received in respect of such assets or equity securities has a fair market value, measured as of the date of the execution of the definitive agreement providing for such acquisition, sale or disposition (or, if no definitive agreement is executed for such acquisition, sale or disposition, the date of the consummation of such acquisition, sale or disposition), in excess of 30% of the aggregate equity

Limitations on Ownership Concentration
The NYSE Group certificate of incorporation provides that no person, either alone or with its related persons (as that term is defined in the NYSE Group certificate of incorporation) may beneficially own shares of stock of NYSE Group representing, in the aggregate, more than 20% of the total number of votes entitled to be cast on any matter unless otherwise approved by the NYSE Group board of directors (in accordance with the requirements of the NYSE Group certificate of incorporation) and the SEC.	Section 26a of the Dutch Act on the Supervision of the Securities Trade (Wet toezicht effectenverkeer 1995) requires a declaration of no objection of the Dutch Minister of Finance of any acquisition or holding of a direct or indirect interest of more than 10% of the outstanding capital or voting rights in Euronext. Such declaration should be granted unless the acquisition harms or could harm the proper functioning of the securities market or investor interests on such securities market or the acquisition hinders or could hinder the proper monitoring of compliance of Euronext with regulatory rules. Similar restrictions also apply to indirect ownership of qualifying interests or specific percentages of voting rights in certain regulated subsidiaries of Euronext.	Same as for NYSE Group, except that any waiver of the ownership concentration limitation must also be approved, to the extent required, by each European regulator having appropriate jurisdiction and authority.

Limitations on Voting Concentration
The NYSE Group certificate of incorporation provides that no person, either alone or with its related persons, may possess the right to vote or cause the voting of shares representing more than 10%, in the aggregate, of the total number of votes entitled to be cast on any matter, and no person, either alone or with its related persons, may acquire the ability to vote more than 10% of the aggregate number of votes being cast on any matter by virtue of agreements entered into by other persons not to vote shares of NYSE Group capital stock. The NYSE Group board of directors may waive the limitations on voting concentration under certain conditions with the approval of the SEC.	Section 26a of the Dutch 1995 Act on the Supervision of Securities Trade (Wet toezicht effectenverkeer 1995) requires declaration of no objection of the Dutch Minister of Finance of any acquisition or holding of a direct or indirect interest of more than 10% of the outstanding capital or voting rights in Euronext. Such declaration should be granted unless the acquisition harms or could harm the proper functioning of the securities market or investor interests on such securities market or the acquisition hinders or could hinder the proper monitoring of compliance of Euronext with regulatory rules. Similar restrictions would also apply to indirect ownership of qualifying interests or specific percentages of voting rights in certain regulated subsidiaries of Euronext (See European Regulation, page [•]).	Same as for NYSE Group, except that any waiver of the voting concentration limitation must also be approved, to the extent required, by each European regulator having appropriate jurisdiction and authority.
Transfer Restrictions
The NYSE Group common stock issued in respect of NYSE memberships in the merger of the NYSE and Archipelago are subject to transfer restrictions. The transfer restrictions were set to expire in three equal installments on each of March 7, 2007, 2008 and 2009. The NYSE Group board of directors, however, has the right to remove these transfer restrictions, in whole or in part, at an earlier date. On May 10, 2006, NYSE Group completed a selling shareholder offering of 28.75 million shares of common stock at $61.50 per	Euronext has not imposed any transfer restrictions on Euronext shares.	Shares of NYSE Euronext common stock issued to NYSE Group stockholders in the merger will be subject to the same transfer restrictions, if any, that they were prior to the merger. Shares of NYSE Euronext common stock issued to the Euronext shareholders in the exchange offer will not be subject to transfer restrictions. For more information, see "Description of NYSE Euronext Capital Stock—Transfer Restrictions on Certain Shares of NYSE Euronext Common Stock."

share, for which NYSE Group received no proceeds. Most of the NYSE Group common stock sold in this offering were shares of NYSE Group common stock that were formerly subject to the transfer restrictions (which the NYSE Group board of directors removed in connection with the offering). If the NYSE Group board of directors releases from the lock-up any of the NYSE Group common stock that General Atlantic or Goldman Sachs Group received in respect of their Archipelago common stock in the NYSE-Archipelago merger, the transfer restrictions will automatically be removed from a proportionate number of shares of NYSE Group common stock held by the former NYSE members. For more information, see "Description of NYSE Euronext Capital Stock—Transfer Restrictions on Certain Shares of NYSE Euronext Common Stock."
Shareholder Proposals
The proposal of business to be considered by the shareholders may be made by any shareholder of NYSE Group by giving notice to the Secretary of NYSE Group within a certain period. Such business must also be a proper matter for shareholder action.	No later than the 50^th day before the day of a meeting of shareholders, shareholders who represent at least 1% of the outstanding share capital of Euronext or represent Euronext shares with a listed value exceeding €50,000,000 may request the Euronext managing board in writing to include their proposals in the notice convening the general meeting of shareholders, provided that doing so does not conflict with any significant corporate interest of Euronext.	Same as for NYSE Group.

Governance
Subject to the rights of the holders of any series of preferred stock to elect additional directors under specified circumstances, the exact number of NYSE Group directors will be fixed from time to time by the NYSE Group board of directors pursuant to a resolution adopted by a majority of the board. Each director holds office until his or her successor is elected and qualified or until his or her earlier resignation or removal.	The Euronext articles of association provide that Euronext is managed by managing board, consisting of one or members. The number of members is determined by the supervisory board. There are currently five members of the managing board. A member of the managing board is appointed for a period of no more than four years and re-appointment may occur for no more than four years per term. The policy of the managing board and the general course of	The number of NYSE Euronext directors immediately following the effective time of the combination will be 20 and may thereafter be changed and fixed from time to time by the NYSE Group board of directors pursuant to a resolution adopted by two-thirds of the directors then in office. In any election of directors, the nominees who shall be elected to the board of directors are the nominees who receive the highest number of votes such that, immediately after the election:
	affairs of Euronext are supervised by the supervisory board. The supervisory board advises the managing board. In discharging its duties, the supervisory board shall be guided by the interests of Euronext and its business. It takes into account the relevant interests of all the stakeholders involved in Euronext (including Euronext's shareholders). The	•	European domiciliaries (i.e., those who, on the date of their election and for the 12 months ending on such date, were domiciled in a country in Europe) constitute the largest number of directors that still constitute a minority of the total number of directors on the NYSE Euronext board of directors; and
	number of members on the Euronext supervisory board is determined by the supervisory board provided that it shall consist of at least three and no more than twelve members. There are currently nine supervisory board members.	•	U.S. domiciliaries (i.e., those who, on the date of their election and for the 12 months ending on such date, were domiciled in the United States) as of such election constitute a majority of the directors then in office.
	A supervisory board member is appointed for a period of four years and a supervisory board member may be in office for a maximum of three four-year periods.	Each director holds office until his or her successor is elected and qualified or until his or her earlier resignation or removal. Under the NYSE Euronext bylaws, either (1) the chairman of the board of directors shall be a U.S. domiciliary and the chief executive officer shall be a

411

		European domiciliary, in each case, as of the most recent election of directors, or (2) the chairman of the board of directors shall be a European domiciliary and the chief executive officer shall be a U.S. domiciliary, in each case, as of the most recent election of directors. The foregoing governance provisions may only be changed by a vote of at least two-thirds of the directors then in office or 80% or more of the votes entitled to be cast by the holders of the then-outstanding NYSE Euronext shares.
Nomination and Appointment of Directors
Directors are elected by the shareholders at each annual meeting of shareholders. Directors are elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. The nomination of a director for election may be made by any shareholder of NYSE Group by giving notice to the Secretary of NYSE Group within a certain period. Any vacancy on the board of directors may be filled only by a majority vote of the remaining directors then in office.	Members of the managing board and the supervisory board are appointed by the general meeting of shareholders. Managing board nominees and supervisory board nominees who are proposed by the supervisory board are appointed by a majority of the votes validly cast. Managing board nominees and supervisory board nominees who are not proposed by the supervisory board must be approved by at least two-thirds of the votes validly cast and representing more than one-third of the outstanding capital.	Same as for NYSE Group except that any notice given to the Secretary of NYSE Euronext purporting to nominate one or more directors must include the documentation necessary to determine whether the nominee is a U.S. domiciliary or a European domiciliary as defined in the bylaws of NYSE Euronext. Vacancies created by the death, retirement, resignation, disqualification or removal from office of a U.S. domiciliary or a European domiciliary must be filled by a U.S. domiciliary or a European domiciliary, respectively. Vacancies created by an increase in the number of directors between annual meetings shall be filled by a European domiciliary (if required in order for European domiciliaries to represent the largest number of directors that can still constitute a minority of the total number

412

		of directors on the board of directors) or otherwise by a U.S. domiciliary.
Removal of Directors
Subject to the rights of holders of any series of preferred stock with respect to directors elected solely by such holders, any director may be removed, with or without cause, by the holders of a majority of the voting power of the shares then entitled to vote at an election of directors. Under Section 19(h)(4) of the Exchange Act, the SEC has the power to remove the director of a U.S. self-regulatory organization from office under certain circumstances.	The general meeting of shareholders is entitled to suspend or dismiss a member of the managing board or the supervisory board at any time. A resolution to suspend or dismiss a member of the managing board or supervisory board must be approved by a two-thirds majority of votes validly cast and representing more than one-third of the outstanding capital. However, if the suspension or dismissal is proposed by the supervisory board, then the resolution may be adopted by a majority of the votes validly cast.	Same as for NYSE Group.
	The supervisory board is also entitled to suspend a member of the managing board.
Amendments to Certificate of Incorporation and Articles of Association
Under the Delaware General Corporation Law, a corporation may amend its certificate of incorporation upon the submission of a proposed amendment to shareholders by the board of directors and the subsequent receipt of the affirmative vote of a majority of its outstanding voting shares and the affirmative vote of a majority of the outstanding shares of each class entitled to vote thereon as a class. The NYSE Group certificate of incorporation provides that NYSE Group reserves the right from time to time to amend or repeal any provision of the NYSE Group certificate of incorporation and that all rights conferred thereby are granted	Under the Euronext articles of association, the general meeting of shareholders may pass a resolution for an amendment to the Euronext articles of association with a majority of the votes cast, at the proposal of the managing board, subject to the approval of the supervisory board. Any such proposal is subject to the prior approval of the Dutch Minister of Finance in the context of the exchange license granted to Euronext and Euronext Amsterdam N.V.	Same as for NYSE Group, except that, in addition, an affirmative vote of not less than 80% of the votes entitled to be cast by holders of the shares of capital stock of NYSE Euronext entitled to vote generally in the election of directors is required to amend or repeal the provision of the certificate of incorporation providing that stockholders may amend the NYSE Euronext bylaws as set forth in Section 10.10(B) thereof. For a description of Section 10.10(B) of the NYSE Euronext bylaws, see "Comparison of Shareholder Rights Prior to and After the Combination—Amendments to Bylaws." In addition, for so long as

Amendments to Bylaws
The NYSE Group board of directors is expressly empowered to adopt, amend or repeal the NYSE Group bylaws. The shareholders may adopt additional bylaws and amend, modify or repeal any bylaw whether or not adopted by them, by a majority of votes cast at a meeting by shareholders entitled to vote.

Automatic Suspension and Repeal of Certain Provisions of the Bylaws
There is no analogous provision in the Bylaws of NYSE Group.	There is no analogous provision in the articles of association of Euronext.	Immediately following the exercise of a Euronext Call Option and for so long as the Dutch foundation shall continue to hold any priority shares or ordinary shares of Euronext, or the voting securities of one or more of its subsidiaries that, taken together, represent a substantial portion of Euronext's business, the application of certain provisions of the combination agreement and of the bylaws of NYSE Euronext including provision relating to the representation of European domiciliaries in the governing bodies of NYSE Euronext shall be suspended.

Appraisal or Dissenters' Rights
Under the Delaware General Corporation Law, a shareholder of a Delaware corporation generally has the right to dissent from a merger or consolidation in which the corporation is participating or a sale of all or substantially all of the assets of the corporation, subject to specified procedural requirements. The Delaware General Corporation Law does not confer appraisal rights, however, if the corporation's stock is either:		Dutch law does not recognize the concept of appraisal or dissenters' rights, and, accordingly, holders of shares in a Dutch company have no appraisal rights.	Same as NYSE Group.
•	listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc.; or

419

•	held of record by more than 2,000 holders.
Even if a corporation's stock meets the foregoing requirements (as NYSE Group's currently does), the Delaware General Corporation Law provides that appraisal rights generally will be permitted if shareholders of the corporation are required to accept for their stock in any merger, consolidation or similar transaction anything other than:
•	shares of the corporation surviving or resulting from the transaction, or depository receipts representing shares of the surviving or resulting corporation, or those shares or depository receipts plus cash in lieu of fractional interests;
•	shares of any other corporation, or depository receipts representing shares of the other corporation, or those shares or depository receipts plus cash in lieu of fractional interests, unless those shares or depository receipts are listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; or
•	any combination of the foregoing.
Preemptive Rights
Under the Delaware General Corporation Law, shareholders have no preemptive rights to subscribe to additional issues of		Under the Euronext articles of association and Dutch law, in the event of an issuance of shares, each shareholder has a	Same as for NYSE Group.

420

The NYSE Group certificate of incorporation does not provide for preemptive rights.	pro rata preemptive right to the number of shares held by such shareholder (with the exception of shares to be issued to employees of Euronext or any group company, including members of the managing board, or shares issued against a contribution other than in cash). Preemptive rights in respect of newly issued shares may be restricted or excluded by the general meeting of shareholders, or subject to approval of the supervisory board, by the managing board if the managing board has been authorized to restrict or exclude preemptive rights (and to issue shares) by the general meeting of shareholders. A resolution to exclude or limit preemptive rights and a resolution to designate the Euronext managing board as the authorized corporate body for the purpose of resolving upon the exclusion or restriction of preemptive rights, requires the approval of at least a majority of the votes cast at a general meeting of shareholders and, if less than one-half of the outstanding share capital is represented at the meeting, the approval of at least two-thirds of the votes cast.
Rights of Purchase and Reduction of Share Capital
Under the Delaware General Corporation Law, a corporation may redeem or repurchase its own shares, except that a corporation cannot generally make such a purchase or redemption if it would cause impairment of its capital.	Under Dutch law, a company may not subscribe for newly issued shares in its own capital. A Dutch limited liability company may, subject to certain restrictions, purchase shares in its own capital, provided the nominal value of the shares held or acquired by the company (or its subsidiaries) does not exceed 10% of the outstanding share	Same as for NYSE Group.

421

	capital. The general meeting of shareholders may reduce the issued share capital of Euronext by cancellation of shares held by Euronext or by reducing the par value of its shares, subject to certain statutory provisions. A resolution of the general meeting of shareholders to reduce the outstanding capital of Euronext may only be adopted at the general meeting if first proposed by the managing board, which proposal is subject to the prior approval of the supervisory board.
Shareholder Suits
Under the Delaware General Corporation Law, a shareholder may bring a derivative action on behalf of the corporation to enforce the rights of the corporation. An individual also may commence a class action suit on behalf of himself and other similarly situated shareholders where the requirements for maintaining a class action under Delaware law have been met. A person may institute and maintain such a suit only if such person was a shareholder at the time of the transaction that is the subject of the suit. Additionally, under Delaware case law, the plaintiff generally must be a shareholder not only at the time of the transaction that is the subject of the suit, but also throughout the duration of the derivative suit. Delaware law also requires that the derivative plaintiff make a demand on the directors of the corporation to assert the corporate claim before the suit may be prosecuted by the	Dutch law does not provide for derivative suits. The Dutch Civil Code provides for representative actions, which are similar to class actions. (However this is not a substitute for, or similar to, a derivative suit). Only a foundation or an association whose objective is to protect the rights of a group of persons having similar interests can institute a representative action. Although such an action cannot result in an award of monetary damages; other types of awards are possible (e.g., to cease and desist or to repay money that was not owed). In most cases, however, the plaintiff in such cases demands a declaratory judgment (verklaring voor recht) establishing that the defendant acted wrongfully and is liable. On the basis of such a judgment each individual person may institute civil proceedings claiming monetary damages. The judgment in the representative action itself is only between the organization and the defendant,	Same as for NYSE Group.

422

derivative plaintiff, unless such demand would be futile.

not between individual class members and the defendant. However, the organization and the defendant may enter into a settlement to be certified by the court. Court certification will have binding effect on the individual class members who do not exercise their right to opt out from the settlement.

Dutch law also provides for the right for (1) one or more shareholders and other persons entitled to attend its annual general meetings jointly representing at least ten percent of the outstanding share capital in Euronext and (2) one or more shareholders jointly representing shares with a par value of at least €225,000 in the aggregate in Euronext, to petition for an investigation (enquête) into the affairs of Euronext.

	•	the right to inspect the shareholders' register.
Conflict of Interest Transactions
The Delaware General Corporation Law generally permits transactions involving a Delaware corporation and an interested director of that corporation if: (1) the material facts as to his or her relationship or interest are disclosed and a majority of disinterested directors consents; (2) the material facts are disclosed as to his or her relationship or interest and a majority of shares entitled to vote thereon consents; or (3) the transaction is fair to the corporation at the time it is authorized by the board of directors, a committee or the shareholders.	The Euronext articles of association provide that, if a member of the managing board has a conflict of interest with Euronext, Euronext shall continue to be represented by two managing directors acting jointly. In the event of a personal conflict of interest of one of the members of the managing board with Euronext, the board resolution regarding the matter to which the conflict of interest relates is subject to the prior approval of the supervisory board. Furthermore, under Dutch law, the general meeting of shareholders is always authorized to appoint one or more persons to represent Euronext in case a member of the managing board has a conflict of interest with Euronext.		Same as for NYSE Group.

424

Action by Written Consent of Shareholders
The NYSE Group certificate of incorporation provides that any action required or permitted to be taken by shareholders must be effected at a duly called annual or special meeting and may not be effected by written consent.	Shareholders of Euronext cannot adopt resolutions outside a general meeting of shareholders.	Same as for NYSE Group.
Limitation of Directors' Liability/Indemnification of Officers and Directors
The Delaware General Corporation Law permits a corporation to include in its certificate of incorporation a provision eliminating or limiting a director's personal liability to the corporation or its shareholders for monetary damages for breaches of fiduciary duty. However, the Delaware General Corporation Law expressly provides that the liability of a director may not be eliminated or limited for: (1) breaches of his or her duty of loyalty to the corporation or its shareholders; (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) the unlawful purchase or redemption of stock or unlawful payment of dividends; or (4) any transaction from which the director derived an improper personal benefit. The Delaware General Corporation Law further provides that no such provision will eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective. NYSE Group's organizational documents provide for the indemnification of directors and executive officers to the fullest	The concept of indemnification of directors of a company for liabilities arising from their actions as members of the managing board or the supervisory board is, in principle, accepted in the Netherlands and sometimes is provided for in a Dutch company's articles of association. Although Dutch law does not contain any provisions in this respect, the Euronext articles of association provide that every current and former member of the managing board and the supervisory board of Euronext be indemnified by Euronext against all costs, charges, losses and liabilities incurred in the proper execution of his or her duties or the proper exercise of his or her power and authority. No right to indemnification exists in the case of willful misconduct or gross negligence (opzet of grove nalatigheid).	Same as for NYSE Group.

425

extent permitted by the Delaware General Corporation Law; provided, however, that, except with respect to claims based on this right to indemnification, NYSE Group shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board. The right to indemnification includes the right to have expenses advanced provided, however, that, if the Delaware General Corporation Law requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to NYSE Group of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section or otherwise.
Generally, the Delaware General Corporation Law permits a corporation to indemnify certain persons made a party to any action, suit or proceeding by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the

426

corporation as a director, officer, employee or agent of another corporation or enterprise, provided that such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation. To the extent that person has been successful in any such matter, that person will be indemnified against expenses actually and reasonably incurred by him. In the case of an action by or in the right of the corporation, no indemnification may be made in respect of any matter as to which that person was adjudged liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which the action was brought determines that, despite the adjudication of liability, that person is fairly and reasonably entitled to indemnity for proper expenses.
(Anti-)Takeover Legislation
Section 203 of the Delaware General Corporation Law generally provides that a Delaware corporation that has not "opted out" of coverage by this section in the prescribed manner may not engage in any "business combination" with an "interested shareholder" for a period of three years following the date that the shareholder became an interested shareholder unless:		Dutch law currently does not provide for mandatory takeover bids. Dutch rules on mandatory takeovers are expected to be implemented by the Dutch Parliament. The EU Takeover Directive should have been implemented by each EU member state no later than May 20, 2006. The EU Takeover Directive applies to all companies governed by the laws of an EU member state of which all or some voting	Same as for NYSE Group.

The laws of the EU member state in which a company has its registered office will determine the percentage of voting rights that is regarded to confer control over that company. On December 23, 2005, the Dutch government published its proposal for the implementation of the EU Takeover Directive (the "Proposal"). Pursuant to the Proposal, any shareholder or group of shareholders acting in concert who could exercise, directly or indirectly, at least thirty percent of the votes in the shareholders' meeting of a Dutch company is considered to control such company. Pursuant to the Proposal, shareholders with controlling interests as of the date on which the new

that does not have a class of voting stock that is:
•		listed on a national security exchange; or
•		held of record by more than 2,000 shareholders;
unless, in each case, this result was directly or indirectly caused by the interested shareholder or from a transaction in which a person became an interested shareholder.
An interested shareholder generally means any person that:
•		is the owner of fifteen percent or more of the outstanding voting stock of the corporation; or
•		is an affiliate or associate of the corporation and was the owner of fifteen percent or more of the outstanding voting stock of the corporation at any time within the three-year period immediately prior to the date on which it is sought to be determined whether this person is an "interested shareholder," and the affiliates and associates of this person.
The term "business combination" is defined to include a wide variety of transactions, including mergers, consolidations, sales or other dispositions of ten percent or more of a corporation's assets and various other transactions that may benefit an interested shareholder.
The NYSE Group certificate of incorporation and bylaws do not contain any provisions opting out of the restrictions prescribed

429

by Section 203 of the Delaware General Corporation Law.
Squeeze-Out Proceedings
Section 253 of the Delaware General Corporation Law provides that a parent corporation owning at least 90% of each class of the stock of a subsidiary entitled to vote on a merger (without applying Section 253) can merge with that subsidiary without advance notice or consent of the minority stockholders upon approval by the parent's board of directors.	If a person, or two or more group companies, (the "Controlling Person"), holds or hold in total at least ninety-five percent of a Dutch public limited liability company's total outstanding share capital by par value for their own account, Dutch law permits the Controlling Person to acquire the remaining shares in the company by initiating proceedings against the holders of the remaining shares. The price to be paid for such shares, in cash only, will be determined by the Enterprise Chamber of the Amsterdam Court of Appeals.	Same as for NYSE Group.
Disclosure of Significant Ownership of Shares
Holders of NYSE Group common stock are subject to certain U.S. reporting requirements under the Exchange Act for shareholders owning more than 5% of any class of equity securities registered pursuant to Section 12 of the Exchange Act. Among the reporting requirements are disclosure obligations intended to keep investors aware of significant accumulations of shares that may lead to a change of control of an issuer. In addition, for shareholders owning more than 10% of any class of equity securities registered pursuant to Section 12 of the Exchange Act, reporting requirements include disclosure of any equity trading in the company.	Holders of Euronext shares may be subject to notification obligations under the Dutch Disclosure Act (Wet melding zeggenschap en kapitaalbelang in effectenuitgevende instellingen 1996, as amended). The following description summarizes those obligations. Pursuant to the Dutch Disclosure Act, any person who, directly or indirectly, acquires or disposes of an interest in Euronext's share capital or voting rights must immediately give written notice to Euronext and, by means of a standard form, to the AFM if, as a result of such acquisition or disposal, the percentage of Euronext's capital interest or voting rights held by such person falls within a different percentage range as compared to the percentage	Same as for NYSE Group.

430

range applicable to the capital interest or voting rights held by such person prior to the acquisition or disposal. The percentage ranges referred to in the Dutch Disclosure Act are 0-5%, 5-10%, 10-15%, 15-20%, 20-25%, 25%-30%, 30-40%, 50-60%, 75-95% and more than 95%.

Upon notification, the AFM shall arrange for publication of the notification in a public registry.

Note 1—Organization and Description of Business

NYSE Group is a holding company that, through its subsidiaries, operates two securities exchanges: the NYSE and NYSE Arca. NYSE Group is a leading provider of securities listing, trading and market data products and services. NYSE Group was formed in connection with the merger of the NYSE and Archipelago, which was completed on March 7, 2006. NYSE Group common stock is listed on the NYSE under the symbol "NYX."

The NYSE is the world's largest cash equities exchange. The NYSE is approximately three times the size of the next largest cash equities exchange in the world in terms of aggregate market capitalization of domestic listed companies.

NYSE Arca operates the first open, all-electronic stock exchange in the United States and has one of the leading market positions in trading exchange-traded funds ("ETFs") and exchange-listed securities. NYSE Arca is also an exchange for trading equity options.

The NYSE owns two-thirds of the Securities Industry Automation Corporation ("SIAC") and reports SIAC's financial results on a consolidated basis. SIAC is an important industry resource providing critical automation and communications services to the NYSE, the American Stock Exchange LLC ("AMEX") and other organizations to support order processing, trading and the reporting of market information, among other functions. SIAC also provides system support for certain national market system functions and for important regulatory and administrative activities. In addition, SIAC provides telecommunication and managed services through its wholly owned subsidiary, Sector, Inc. ("Sector"), to subscribers primarily in the securities industry.

The regulatory functions of the NYSE and NYSE Arca are conducted by NYSE Regulation, a separate not-for-profit subsidiary of NYSE Group.

Note 2—Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts of NYSE Group and all wholly-owned subsidiaries, as well as of SIAC. The results of operations of Archipelago have been included in NYSE Group's results of operations since March 8, 2006.

The accompanying condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and reflect all adjustments, consisting of only normal recurring adjustments, that are, in the opinion of management, necessary for a fair statement of the results for the period. All material intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in financial statements, which are normally required under accounting principles generally accepted in the United States, have been condensed or omitted; however, management believes that the disclosures are adequate to make the information presented not misleading.

The preparation of these condensed consolidated financial statements, in conformity with accounting principles generally accepted in the United States, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could be materially different from these estimates. Certain prior period amounts have been reclassified to conform to the current period's presentation.

Operating results for the three and six months ended June 30, 2006 are not necessarily indicative of the results that may be expected for the year ending December 31, 2006.

Note 3—Business Combinations

Archipelago Holdings, Inc.

On March 7, 2006, Archipelago and the NYSE combined their businesses and became wholly-owned subsidiaries of NYSE Group, a newly created, for profit and publicly traded holding company. Through the merger, NYSE Group intends to continue to grow market position in trading volume and enhance the trading technology of both the NYSE and NYSE Arca. Together, the NYSE and NYSE Arca provide a full-service market that offers customers a choice of products and appeals to all types of investors.

On March 7, 2006, each of the 1,366 members of the NYSE was entitled to receive $300,000 in cash and 80,177 shares of NYSE Group common stock in exchange for its NYSE membership. In addition, a cash dividend of $70,571 was declared and paid to each of the 1,366 members. Each NYSE member had the opportunity to make either a cash election to increase the cash portion (and decrease the stock portion) of their merger consideration, or a stock election to increase the stock portion (and decrease the cash portion) of their merger consideration. The aggregate number of shares of NYSE Group common stock issued to all of the NYSE members in the merger, together with the aggregate number of shares reserved for issuance to NYSE employees, equaled approximately 70% of NYSE Group common stock issued and outstanding, or approximately 109.5 million shares.

On March 7, 2006, (i) each share of the issued and outstanding shares of Archipelago's common stock was converted automatically into the right to receive one share of NYSE Group common stock, (ii) all outstanding stock options of Archipelago, whether vested or unvested, converted into options to purchase an equivalent number of shares of NYSE Group common stock, and (iii) all outstanding restricted stock units of Archipelago converted into an equal number of restricted stock units of NYSE Group common stock. The aggregate number of shares (including shares underlying stock options and restricted stock units) received by Archipelago stockholders, equaled approximately 30% of the issued and outstanding shares of NYSE Group common stock, or approximately 46.0 million shares.

Under the purchase method of accounting, the total merger consideration, which was determined based on the fair market value of Archipelago common stock beginning two days before and ending after April 20, 2005 (the date the merger was agreed to and announced), was $1,085.1 million. The results of operations of Archipelago have been included in NYSE Group's results of operations since March 8, 2006.

The following is a summary of the purchase price in the Archipelago merger (in thousands):

Purchase price		$	1,085,113

The purchase price was allocated to the assets acquired and liabilities assumed based on the estimated fair value of Archipelago net assets as of the merger date as follows (in thousands):

Historical cost of net assets acquired		$	458,290
Elimination of Archipelago's historical goodwill and intangibles			(240,095	)
Adjustment to fair value of property and equipment			17,000

Goodwill			528,771

	Total purchase price	$	1,110,535

The allocation of the purchase price to Archipelago assets and liabilities are only preliminary allocations based on estimates of fair values and will change when estimates are finalized. Therefore, the information above is subject to change pending the final allocation of purchase price. NYSE Group does not expect any of the goodwill to be deductible for tax purposes.

During 2005, NYSE Group adopted a plan to eliminate positions. As a result of this decision, NYSE Group recorded a $3.9 million charge consisting of severance and related costs during 2005. For the six months ended June 30, 2006, NYSE Group recorded a $5.8 million charge due to 77 additional positions being eliminated as a result of our continued integration efforts and cost containment initiatives. These positions were primarily included within trading floor operations and miscellaneous administrative areas. The following is a summary of the severance charges and utilization for the six months ended June 30, 2006 and the remaining accrual at June 30, 2006 (in thousands):

Balance at December 31, 2005	$	3,804
Additional severance		5,825
Amount paid in 2006		(1,423	)

Balance at June 30, 2006	$	8,206

These costs associated with the additional severance for the six months ended June 30, 2006 are included in merger expenses and related exists costs in the condensed consolidated statements of income. Based on current severance dates and the accrued severance at June 30, 2006, NYSE Group expects to pay these amounts through 2007.

PCX Holdings, Inc. and Wave Securities, LLC

On September 26, 2005, Archipelago completed its acquisition of PCX Holdings ("PCX") for a total purchase price of approximately $94.0 million consisting of a $90.9 million cash payment to PCX stockholders and certain employees of PCX, and approximately $3.1 million of direct acquisition costs incurred by Archipelago. As part of the acquisition of PCX, Archipelago undertook to divest Wave Securities LLC ("Wave Securities"), a previously wholly-owned subsidiary of Archipelago. On March 3, 2006, Archipelago completed the sale of Wave Securities.

Note 4—Combination with Euronext N.V.

On May 22, 2006, NYSE Group proposed a business combination with Euronext that would create NYSE Euronext, a global marketplace with an expected combined market capitalization of approximately $21 billion.

Euronext is a cross-border exchange providing international services for regulated cash markets and derivative markets in Belgium, France, the United Kingdom, the Netherlands and Portugal.

Both parties signed a definitive combination agreement on June 1, 2006. The combination is expected to close during the first quarter of 2007 and is subject to regulatory approval and the approval of NYSE Group and Euronext shareholders.

In the combination, NYSE Group and Euronext will combine their businesses under NYSE Euronext, a Delaware corporation formed for the purpose of this transaction. Euronext's business will be brought under NYSE Euronext through an exchange offer and a post-closing reorganization, and NYSE Group's business will be brought under NYSE Euronext through a merger.

In the exchange offer, NYSE Euronext or its subsidiary will offer to acquire each outstanding Euronext ordinary share in exchange for €21.32 in cash and 0.98 of a share of NYSE Euronext common stock. The exchange offer also will have a mix and match election to permit Euronext shareholders to elect all cash or all stock in exchange for their Euronext ordinary shares, subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all exchanging Euronext shareholders received the standard offer consideration.

Following the successful completion of the exchange offer, a wholly owned subsidiary of NYSE Euronext will merge with NYSE Group, and, as a result, NYSE Group will become a wholly owned subsidiary of NYSE Euronext, and each share of NYSE Group common stock will be converted into the right to receive one share of NYSE Euronext common stock.

Note 4—Combination with Euronext N.V. (Continued)

As soon as possible after the completion of these transactions, NYSE Euronext intends to effectuate a corporate reorganization of Euronext and its subsidiaries for the purpose of providing Euronext shareholders who did not exchange their Euronext ordinary shares in the exchange offer with the same consideration that such shareholders would have received had they tendered their Euronext ordinary shares in the exchange offer.

Note 5—Segment Information

Subsequent to the merger with Archipelago, NYSE Group operates under three reportable segments: Market, SIAC Services and Regulation. NYSE Group's segments are managed and operated as three business units and organized based on services provided to customers.

Market represents primarily the fees earned from (i) obtaining new listings and servicing existing listings on the NYSE and NYSE Arca, (ii) providing access to trade execution, (iii) distributing market information to data subscribers and (iv) issuing trading licenses (previously membership fees).

SIAC Services provides communication and data processing operations and systems development functions to the NYSE and third-party customers.

Regulation provides regulatory services (including member firm regulation, market surveillance, enforcement, listed company compliance and arbitration), performed by NYSE Regulation, to the NYSE and NYSE Arca. Regulatory fees are paid by member organizations and are primarily assessed based upon their Gross FOCUS revenues. In addition, Regulation collects regulatory fines that are levied against members and member organizations.

Note 5—Segment Information (Continued)

SIAC operates on a cost recovery model driven by its customers' demands. Under this model, any increase or decrease in SIAC's expenses typically results in a corresponding change in its revenues. During the three and six months ended June 30, 2006, SIAC incurred $2.0 million and $15.6 million, respectively, related to stock-based compensation for awards granted to certain of its employees as part of the merger with Archipelago. There was no corresponding increase in revenue, as this expense was not shared with non-NYSE Group customers.

Note 7—Stock-Based Compensation (Continued)

Archipelago, 0.2 million shares underlying restricted stock units granted to former Archipelago directors, officers and employees and 2.6 million shares underlying stock options granted to former Archipelago directors, officers and employees were converted to restricted stock and stock options, respectively, of NYSE Group.

On March 8, 2006, NYSE Group granted approximately 1.2 million restricted stock units to NYSE employees and certain SIAC employees under the Plan. These restricted stock units vest 50% on the grant date and 25% on each of the first and second anniversaries of the grant date. Compensation expense is based on the market price of the shares underlying the awards on the grant date and recognized ratably over the vesting period. NYSE Group estimates an expected forfeiture rate while recognizing the expense associated with these awards. As of June 30, 2006, the employees of NYSE Group held approximately 1.8 million stock options with a weighted average exercise price of $14.09 (1.4 million of which were exercisable at a weighted average exercise price of $14.37) and 1.4 million restricted stock units. As of June 30, 2006, the total aggregate intrinsic value of stock options outstanding and exercisable was $99.5 million and $77.1 million, respectively.

For the three and six months ended June 30, 2006, NYSE Group recorded $5.9 million and $40.5 million, respectively, of stock-based compensation included in compensation in the condensed consolidated statements of income. As of June 30, 2006, there was approximately $23.9 million of total unrecognized compensation cost related to stock options and restricted stock units. This cost is expected to be recognized over approximately three years.

Note 8—Retirement Benefits

During 2005, the NYSE and SIAC announced that effective March 31, 2006, the future benefit accrual of all active participants in the pension plans and supplemental executive retirement plan ("SERP") will be frozen. Effective April 1, 2006, NYSE Group employees became eligible to receive benefits from a new employer-funded defined contribution Retirement Accumulation Plan ("RAP"). RAP expense incurred for the three months ended June 30, 2006 was $2.8 million.

NYSE and SIAC currently do not expect to provide any additional funding to the pension plans during 2006.

Note 9—Related Party Transactions

The Depository Trust Company ("DTC") and the National Securities Clearing Corporation ("NSCC") are wholly-owned subsidiaries of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is a holding company that supports DTC, which provides settlement and custody services to banks and broker-dealers, and NSCC, which provides trade clearance, netting and settlement services to banks, broker-dealers, mutual funds, insurance companies and other financial institutions.

On March 28, 2006, NYSE Group sold its shares of DTCC common stock, which represented approximately 28% of DTCC's common stock, for a $23.4 million cash payment. NYSE Group carried this investment at its $2.5 million cost and therefore realized a $20.9 million pre-tax gain that was included in gain on sale of equity investment for the six months ended June 30, 2006 in the condensed consolidated statements of income. The after-tax impact of this gain was included in the cash dividend paid to each former NYSE member in connection with the merger of NYSE and Archipelago. As of June 30, 2006, NYSE Group owns 50% of the outstanding preferred stock of DTCC.

SIAC performs services for AMEX, which is a one-third owner of SIAC.

In re NYSE Specialists Securities Litigation

On June 2, 2006, plaintiffs filed in the U.S. Court of Appeals for the 2d Circuit an opening brief in support of their appeal from the decision of the U.S. District Court for the Southern District of New York entering a final judgment in favor of NYSE. NYSE filed its brief in opposition on August 2, 2006.

Merger-Related Litigation

In March 2006, Janet Hyman and Sylvia Lief, each a former NYSE member, filed separate complaints in New York Supreme Court against NYSE and John A. Thain. The complaints sought compensatory damages for alleged breach of fiduciary duty based on a purported duty of defendants to disclose NYSE's merger discussions with Archipelago prior to the sale of plaintiffs' NYSE memberships on March 1 and 2, 2005, respectively.

On April 19, 2006, NYSE and Mr. Thain served motions to dismiss the Hyman and Lief complaints. On June 9, 2006, Ms. Hyman and Ms. Lief each served an amended complaint, which added an additional cause of action for breach of fiduciary duty and a new cause of action for negligence. On June 22, 2006, D. Paul Rittmaster, another former NYSE member represented by the same law firm as Ms. Hyman and Ms. Lief, filed a complaint in New York Supreme Court against NYSE and Mr. Thain asserting the same causes of action alleged in the amended complaints of Hyman and Lief. On July 28, 2006, NYSE and Mr. Thain served a motion to dismiss the Hyman and Lief amended complaints and the Rittmaster complaint on the grounds, among others, that defendants had no legal duty to make the disclosures plaintiffs assert they should have made.

Compensation-Related Litigation

On July 26, 2006, the court denied the motion of defendant Kenneth Langone for summary judgment in his favor on the single cause of action asserted against him by the New York Attorney General; Mr. Langone has appealed that denial. On July 17, 2006, NYSE and former NYSE Chairman John S. Reed filed motions for summary judgment dismissing all of Richard Grasso's counterclaims against them. On July 31, 2006, the New York Attorney General filed a motion for partial summary judgment in its favor on claims asserted against Mr. Grasso, and Mr. Grasso filed motions for summary judgment in his favor with respect to three of the six causes of action asserted against him by the Attorney General. Mr. Grasso also has moved for summary judgment dismissing the one claim asserted by the Attorney General against NYSE. In addition, defendant Carl McCall has moved for summary judgment dismissing the third-party claims asserted against him by Mr. Grasso. On August 8, 2006, the court ruled that the New York Attorney General's claim against Mr. Grasso for restitution and imposition of a constructive trust is an equitable claim that must be tried to the court rather than to a jury, and that it will commence trial of that claim (which will be tried separately from all other claims asserted in the case) on October 16, 2006. The appellate court has not yet rendered a decision on Mr. Grasso's appeal of the trial court's denial of his motion to dismiss four of the six claims against him, including the claim for restitution and imposition of a constructive trust now scheduled for trial in October.

Employment-Related Litigation

On April 20, 2006, Graciela DaSilva, Vjoca Selmanovic and Robin Max Morris filed a complaint in the U.S. District Court for the Southern District of New York against NYSE Group, Building Maintenance Service, LLC ("BMS"), a cleaning service contractor, and five unnamed corporations, seeking compensatory and punitive damages for alleged gender discrimination and retaliation in violation of federal and local laws. Ms. DaSilva currently is employed as a porter by NYSE Group; Mr. Morris previously was employed by NYSE as a supervisor of porters. Mr. Selmanovic previously was employed as a porter by BMS. On May 24, 2006, NYSE Group filed an answer to the complaint in which it denied allegations of wrongdoing and asserted various defenses.

Other Matters

On or about April 25, 2006, the Independent Broker Action Committee, Inc. ("IBAC"), which describes itself as a not-for-profit corporation whose membership consists of independent NYSE brokers, filed a petition in the U.S. Court of Appeals for the District of Columbia ("DC Circuit") seeking review of two orders issued by the SEC (Exchange Act Releases No. 34-53539 (March 22, 2006) and 34-53382 (February 27, 2006) (the "Orders")) insofar as they relate to the creation of the NYSE Hybrid Market^SM and NYSE's proposed method of allocating trading rights. The petition named the SEC as respondent and asked the court to vacate Exchange Act Release No. 34-53539 regarding the NYSE Hybrid Market^SM and that portion of Exchange Act Release No. 34-53382 that approved NYSE's proposed method of allocating trading rights at NYSE through annual trading licenses, and to remand the matter to the SEC for further proceedings. IBAC also asked the SEC to stay the authorization given to NYSE under Exchange Act Release No. 34-53539 to implement subsequent phases of the NYSE Hybrid Market^SM, pending the court's resolution of IBAC's petition for review.

NYSE submitted an opposition to IBAC's stay request before the SEC and was granted leave to intervene to oppose IBAC's petition before the DC Circuit. Following joint requests to the SEC and the DC Circuit, the SEC has deferred ruling on IBAC's stay request and the DC Circuit has deferred briefing on the petition itself, to allow IBAC to determine whether it wishes to continue to pursue the petition in light of subsequent developments with regard to the NYSE Hybrid Market^SM.

NYSE Group is defending a number of other actions and investigations, the ultimate outcome of which cannot reasonably be determined at this time. In the opinion of management and legal counsel, the aggregate of all possible losses from all such other actions and investigations should not have a material adverse effect on the consolidated financial condition or results of operations of NYSE Group.

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Organization and Description of Business

NYSE Group, Inc. was formed for the purpose of consummating the business combination of the New York Stock Exchange, Inc. (the "NYSE") and Archipelago Holdings, Inc., which was completed on March 7, 2006 (see Note 3). The merger of the NYSE and Archipelago has been treated as a purchase business combination for accounting purposes, with the NYSE designated as the acquirer. As such, the historical financial statements of the NYSE have become the historical financial statements of NYSE Group.

The NYSE is a New York Type A not-for-profit corporation, incorporated in 1971. It is registered as a national securities exchange and is a self-regulatory organization ("SRO"). The NYSE is the world's largest cash equities market, both in terms of average daily trading volume and in the market capitalization of its listed companies.

The NYSE owns two-thirds of the Securities Industry Automation Corporation ("SIAC") and reports SIAC's financial results on a consolidated basis. SIAC is an important industry resource providing critical automation and communications services to the NYSE, the American Stock Exchange ("AMEX") and other organizations to support order processing, trading and the reporting of market information, among other functions. SIAC also provides system support for certain national market system functions and for important regulatory and administrative activities. In addition, SIAC provides telecommunication and managed services through its wholly-owned subsidiary, Sector, Inc. ("Sector"), to subscribers primarily in the securities industry.

Note 2—Basis of Presentation and Significant Accounting Policies

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could be materially different from these estimates. Certain prior-year amounts have been reclassified to conform to the current year's presentation.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the NYSE and all wholly-owned subsidiaries, as well as SIAC. All intercompany transactions have been eliminated in consolidation. Minority interest in the consolidated statements of income represents AMEX's share of the income or loss of SIAC. The minority interest in the consolidated statements of financial condition reflects the original investment by AMEX in SIAC, along with its proportional share of the earnings or losses of SIAC.

The NYSE's investment in The Depository Trust & Clearing Corporation ("DTCC"), which is operated by separate management and has a separate board of directors, is carried at cost as the NYSE has less than majority ownership and does not exercise significant influence over the operating and financial policies of DTCC. The carrying balance is reflected in the consolidated statements of financial condition in investments in affiliates.

Note 2—Basis of Presentation and Significant Accounting Policies (Continued)

Cash and Cash Equivalents

Cash and cash equivalents are comprised of cash and highly liquid investments with an original maturity of three months or less.

Revenue Recognition

Data processing fees represent revenue generated by SIAC for providing communication services, data processing operations and systems development functions to the NYSE and third-party customers. SIAC's revenue from the NYSE is eliminated in consolidation. It is SIAC's policy to charge affiliates and other customers, other than Sector's customers, at approximate cost. Sector's customers are billed at competitive rates for the services provided. Fees are accrued and recognized as services are provided.

Market information fees are paid by members, member organizations, institutional investors and other subscribers to access last sale and bid/ask information. The fees are primarily based upon the number of interrogation devices receiving the market information. Fees are accrued and recognized as services are rendered.

Trading fees are paid monthly by members and member organizations and are calculated based upon trading activity brought to the floor of the NYSE. These fees are accrued and recognized as earned.

Regulatory fees are paid by members and member organizations and are primarily assessed based upon their gross FOCUS revenues. They are recognized ratably over the period to which they apply. Regulatory fees also include regulatory fines that are levied by the NYSE. These fees are recognized when collection is reasonably assured.

Facility and equipment fees are paid to the NYSE for services provided on the trading floor. They are accrued and recognized when services are rendered.

Securities Purchased under Agreements to Resell

The NYSE invests funds in overnight reverse repurchase agreements, which provide for the delivery of cash in exchange for securities having a market value of approximately 102% of the amount of the agreements. Independent custodians take possession of the securities in the name of the NYSE. Overnight reverse repurchase agreements are recorded at trade date at the contractual amount.

Investment Securities

NYSE's investment securities are classified as available-for-sale securities and are carried at fair value as of trade date with the unrealized gains and losses, net of tax, reported as a component of other comprehensive income. Interest income on investment securities, including amortization of premiums and accretion of discounts, is accrued and recognized over the life of the investment. The specific identification

FIN-29

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Basis of Presentation and Significant Accounting Policies (Continued)

method is used to determine realized gains and losses on sales of investment securities, which are reported in investment and other income.

The NYSE regularly reviews its investments to determine whether a decline in fair value below the cost basis is other than temporary. If events and circumstances indicate that a decline in the value of the assets has occurred and is deemed to be other-than-temporary, the cost basis of the security is written down to fair value and a corresponding impairment is charged to earnings. As of December 31, 2005, no unrealized losses were considered other-than-temporary.

Accounts Receivable, Net

Accounts receivable represents payments due to the NYSE for services rendered. An allowance is established to record receivables at a net amount equal to the net realizable value. The allowance for bad debts is maintained at a level that management believes to be sufficient to absorb probable losses in the NYSE's accounts receivable portfolio and is assessed periodically by management. Increases in the allowance for doubtful accounts are charged against operating results and the allowance is decreased by the amount of write-offs, net of recoveries. The allowance is based on several factors, including a continuous assessment of the collectibility of each account. In circumstances where a specific customer's inability to meet its financial obligations is known, the NYSE records a specific provision for bad debts against amounts due to reduce the receivable to the amount it reasonably believes will be collected. Accounts with outstanding balances in excess of 60 to 90 days are reviewed monthly to make changes to the allowance as appropriate.

The NYSE's receivables are primarily from members, member organizations, listed companies and market information subscribers. The concentration of risk on accounts receivable is mitigated by the large number of entities comprising the NYSE's customer base. The total allowance, netted against receivables, was $8.0 million at December 31, 2005 and $14.4 million at December 31, 2004. For the year ended December 31, 2005, there was an $18,000 release of reserve balances and additional provisions recorded of $1.6 million and $0.7 million for the years ended December 31, 2004 and 2003, respectively, while write-offs were $6.4 million, $1.8 million and $1.4 million, respectively.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation of assets is determined by using the straight-line method of depreciation over the estimated useful lives of the assets, which range from 2 to 15 years. Leasehold improvements are amortized using the straight-line method over the term of the lease or the estimated useful lives of the assets, whichever is shorter. Set forth below are the estimated useful lives of the NYSE's assets:

Buildings and improvements		14 years
Leasehold improvements		5-14 years
Computers and equipment		2-15 years
Furniture and fixtures		5 years

The NYSE accounts for software development costs under AICPA Statement of Position 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use" ("SOP 98-1"), and other related guidance. The NYSE expenses software development costs incurred during the

FIN-30

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Basis of Presentation and Significant Accounting Policies (Continued)

preliminary project stage, while it capitalizes costs incurred during the application development stage, which includes design, coding, installation and testing activities. Amortization of capitalized software development costs is computed on a straight-line basis over the software's estimated useful life, generally three years.

Revisions in estimated useful lives of depreciable assets were made in 2004. The effect of changes in estimates of useful lives for depreciable assets was to decrease net income in 2004 by $7.6 million.

Expenditures for repairs and maintenance are charged to operations in the period incurred. The cost and accumulated depreciation of property and equipment retired or otherwise disposed of are removed from the accounts upon disposal and any gain or loss is reflected in operations.

Activity Assessment Fees and Section 31 Fees

The NYSE pays SEC fees pursuant to Section 31 of the Exchange Act. These fees are designed to recover the costs to the government for the supervision and regulation of securities markets and securities professionals. The NYSE, in turn, collects activity assessment fees from member organizations clearing or settling trades on the NYSE and recognizes these amounts when members are invoiced. Fees received are included in cash of the NYSE at the time of receipt and, as required by law, the amount due to the SEC is remitted semiannually and recorded as an accrued liability until paid. The NYSE records activity assessment fee revenue and Section 31 fees expense on its consolidated statements of income as the NYSE bears the credit risk associated with the collection of these fees.

As of December 31, 2005, the NYSE has accumulated a $15.1 million excess of anticipated activity remittance fees to the SEC, which is included in Section 31 fees payable on the consolidated statements of financial condition. Due to the uncertainty of the claims on the excess remittances, the NYSE has discussed these issues with the SEC Market Regulation Division, SROs, member organizations and others in the securities industry who have had the same or similar issues and it plans to work with industry participants and the SEC to review and determine a satisfactory resolution of this matter with the consideration of all stakeholders involved.

Compensation and Accrued Employee Benefits

The NYSE accrues for compensation as earned. The NYSE and SIAC have separate qualified defined benefit pension plans covering substantially all employees meeting age and service requirements. Each also has a Supplemental Executive Retirement Plan. All of these plans are accounted for under Statement of Financial Accounting Standard ("SFAS") No. 87 "Employers Accounting for Pensions." In addition, the NYSE and SIAC maintain defined benefit plans to provide certain health care and life insurance benefits for eligible retired employees. These plans are accounted for under SFAS No. 106 "Employers Accounting for Postretirement Benefits Other than Pensions."

Pension and OPEB costs and liabilities are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest cost, expected return on assets, mortality rates and other factors. In accordance with U.S. generally accepted accounting principles, actual results that differ from the assumptions are accumulated and amortized over the future periods and, therefore, generally affect recognized expense and the recorded obligation in future periods. While management believes that the assumptions used are appropriate,

FIN-31

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Basis of Presentation and Significant Accounting Policies (Continued)

differences in actual experience or changes in assumptions may affect NYSE's pension and other postretirement obligations and future expense.

Comprehensive Income

SFAS No. 130, "Reporting Comprehensive Income," establishes guidelines for reporting and display of comprehensive income and its components in the financial statements. Other comprehensive income includes changes in unrealized gains and losses on investment securities classified as available-for-sale and changes in minimum pension liabilities, net of tax. Accumulated other comprehensive income (loss) is included as a component of Members' Equity.

Income Taxes

The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax assets and liabilities for the future tax consequences of events that have been recognized in an entity's financial statements or tax returns. The NYSE reviews its deferred tax asset for recovery; when the NYSE believes that it is more likely than not that a portion of its deferred tax assets will not be realized, a valuation allowance will be established. As of December 31, 2005, the asset is expected to be fully realized and accordingly, no valuation allowance has been established. Significant judgment is required in assessing the future tax consequences of events that have been recognized in the NYSE's financial statements or tax returns. Fluctuations in the actual outcome of these future tax consequences could have material impact on the NYSE's financial position or results of operations.

The NYSE files a consolidated tax return with its subsidiaries except SIAC, which is required to file its tax return on a stand-alone basis. The amounts recorded for consolidated financial reporting purposes equals the aggregation of the stand-alone provisions of both entities.

Estimated Fair Value of Financial Instruments

SFAS No. 107, "Disclosures about Fair Value of Financial Instruments," requires the disclosure of the fair value of financial instruments, including assets and liabilities recognized in the consolidated statements of financial condition. Management estimates that the fair value of financial instruments recognized in the consolidated statements of financial condition (including cash and cash equivalents, securities purchased under agreements to resell, investment securities, receivables, accounts payable, accrued expenses and accrued employee benefits) approximates their fair value due to the short-term nature of these assets and liabilities.

Note 3—Merger with Archipelago Holdings, Inc.

On April 20, 2005, the NYSE entered into a definitive merger agreement with the Archipelago Holdings, Inc. ("Archipelago"), the first open all-electronic stock market, pursuant to which Archipelago and the NYSE agreed to combine their businesses and become wholly-owned subsidiaries of NYSE Group, Inc., a newly created, for-profit holding company.

The merger closed on March 7, 2006. As of that date, the NYSE became a wholly-owned subsidiary of NYSE Group. NYSE Group common stock is listed on the NYSE and is traded under the symbol "NYX."

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 3—Merger with Archipelago Holdings, Inc. (Continued)

In the merger, each NYSE member was entitled to receive, in exchange for its NYSE membership, $300,000 in cash and 80,177 shares of NYSE Group common stock. Each NYSE member had the opportunity to make either a cash election to increase the cash portion (and decrease the stock portion) of their merger consideration, or a stock election to increase the stock portion (and decrease the cash portion) of their merger consideration. These elections were subject to certain proration. The aggregate number of shares of NYSE Group Common Stock issued to all of the NYSE members in the merger, together with the aggregate number of shares reserved for issuance to NYSE employees, equaled approximately 70% of the NYSE Group common stock issued and outstanding at the closing of the merger, on a diluted basis.

In the merger, Archipelago was impacted as follows: (i) each share of the issued and outstanding shares of Archipelago's common stock converted automatically into the right to receive one share of NYSE Group common stock; (ii) all outstanding stock options of Archipelago, whether vested or unvested, converted into options to purchase an equivalent number of shares of NYSE Group common stock; and (iii) all outstanding restricted stock units of Archipelago converted into an equal number of restricted stock units of NYSE Group common stock. The aggregate number of shares (including shares underlying stock options and restricted stock units) received by Archipelago's stockholders equaled approximately 30% of the issued and outstanding shares of NYSE Group common stock at the closing of the merger, on a diluted basis.

During the fourth quarter of 2005, the NYSE started reviewing its cost structure in connection with its pending merger with Archipelago and the shift towards a for-profit model.

In November 2005, the NYSE adopted a plan to eliminate approximately 70 positions, primarily in trading floor operations and miscellaneous administrative areas. As a result of this decision, the NYSE recorded a $3.9 million charge consisting of severance and related costs. The following is a summary of the severance charges recognized in December 2005 and the remaining accruals at December 31, 2005 (in thousands):

	NYSE Market
Total severance charges	$	3,910
Amount paid in 2005		(106	)

Balance at December 31, 2005	$	3,804

The amount accrued for severance is based upon the NYSE's severance policy and the positions eliminated. Based upon current severance dates and the accrued severance at December 31, 2005, the NYSE expects to pay these amounts in each quarter, through the third quarter of 2007.

These costs were included in the Archipelago merger and related costs in the consolidated statement of income for the year ended December 31, 2005.

The NYSE owns both common and preferred stock of DTCC. As of December 31, 2005 and 2004, the NYSE held approximately 28% interest in the common stock of DTCC at a cost of $2.4 million. The entitlement to own the common stock of DTCC is re-determined periodically, based on usage of DTCC by the participants. The NYSE may acquire or may be required to sell any shares not purchased or sold by certain users of DTCC's services.

The NYSE also owned 50% of the preferred stock of DTCC at a cost of $0.3 million as of December 31, 2005 and 2004. The cost of the investment in common and preferred stock is included in investment in affiliates on the consolidated statement of financial condition.

No valuation allowance for the deferred tax asset was necessary at December 31, 2005 or 2004 as management believes it is more likely than not that the assets will be realized.

For the tax year ended December 31, 2004, the NYSE and subsidiary companies reported a net operating loss of approximately $2.6 million to New York State and New York City. New York State and City Tax Law allow the losses incurred to be carried forward and used to offset income in future years. These losses, under New York State and City Tax Law must be utilized within 20 years of being incurred. The losses are scheduled to be fully utilized upon completion of the 2005 tax return.

Note 9—Segment Reporting

Management operates under two reportable segments, NYSE Market and SIAC Services. The segments are managed and operated as two business units and organized based on services provided to customers. After completion of the merger with Archipelago, the NYSE will be a subsidiary of NYSE Group, which may operate and manage its businesses in a different manner and under different reportable segments.

NYSE Market represents the fees earned from obtaining new listings and retaining existing listings on the NYSE, access to executing trades on the NYSE and distribution of market information to data subscribers as well as membership fees, regulatory fees and investment and other income.

SIAC Services provides communication services, data processing operations and systems development functions to the NYSE and third-party customers, which are included in data processing fees on the consolidated statements of income.

Expenses for NYSE Market and SIAC services are the direct expenses related to running those businesses.

Note 10—Litigation and Other Matters

The following is a summary of relevant legal matters as of December 31, 2005:

In re NYSE Specialists Securities Litigation

In December 2003, the California Public Employees' Retirement System ("CalPERS") filed a purported class action complaint in the United States District Court for the Southern District of New York (the "Southern District") against the NYSE, NYSE specialist firms, and others, alleging various violations of the Exchange Act and breach of fiduciary duty, on behalf of a purported class of persons who bought or sold unspecified NYSE-listed stocks between 1998 and 2003. Judge Robert Sweet consolidated CalPERS' suit with three other purported class actions and a non-class action into the action now entitled In re NYSE Specialists Securities Litigation, and appointed CalPERS and Empire Programs, Inc. co-lead plaintiffs.

manipulated prices, enriching Defendants and damaging Plaintiffs and the Class." The consolidated complaint also alleges that certain generalized NYSE statements concerning the operation of its market were rendered false and misleading by the NYSE's non-disclosure of its alleged failure to properly regulate specialists, and that the NYSE was motivated to participate in or permit the specialist firms' alleged improper trading in order to maintain or enhance its fee revenues and the compensation of its executives, including its former chairman and chief executive officer Richard A. Grasso. The consolidated complaint seeks unspecified compensatory damages against defendants, jointly and severally.

On November 16, 2004, the specialist firms and the NYSE filed motions to dismiss the complaint. On December 12, 2005, the court granted the NYSE's motion and dismissed all of the claims against it with prejudice. The court granted in part and denied in part the motions to dismiss of the specialist defendants.

Papyrus Patent Infringement Litigation

On January 27, 2004, Papyrus Technology Corporation ("Papyrus") filed a complaint in the Southern District against the NYSE, alleging that the NYSE's Wireless Data System and Broker Booth Support System infringe patents allegedly issued to Papyrus and that the NYSE breached a license agreement with Papyrus. The NYSE answered the complaint, asserting affirmative defenses and a counterclaim against Papyrus. Discovery has been completed. It is anticipated that the parties will file motions for summary judgment on at least some of the claims. The court has not set a trial date.

SEC Administrative Proceeding Regarding Specialists

On April 12, 2005, the SEC instituted and simultaneously settled an administrative proceeding against the NYSE. The SEC action related to detection and prevention of activities of specialists who engaged in unlawful proprietary trading on the floor of the NYSE. The SEC found that the NYSE had violated Section 19(g) of the Exchange Act by failing to enforce compliance with the federal securities laws and NYSE rules that prohibit specialists from "interpositioning" and "trading ahead" of customer orders. In settling the action, the NYSE consented, without admitting or denying the findings, to entry of an administrative order imposing a censure and requiring the NYSE to cease and desist from future violations of Section 19(g) and to adopt various remedial measures, including retention of a third-party regulatory auditor, creation of a $20 million reserve fund in connection therewith, development of policies and procedures to enhance its regulation of floor members, implementation of a pilot program for an on-floor video and audio surveillance system, development of systems and procedures to track the identity of specialists and clerks trading on the NYSE trading floor, and enhancements to its trading systems reasonably designed to prevent specialists from trading ahead of customer orders and interpositioning. As part of its settlement, the NYSE agreed to cooperate with the SEC in all continuing investigations, litigations or other proceedings concerning the matters described in the administrative order.

Merger-Related Litigation

Following the announcement, on April 20, 2005, of the NYSE's proposed merger with Archipelago Holdings, Inc., several lawsuits were filed relating to the merger.

On May 9, 2005, William J. Higgins filed a complaint in New York Supreme Court, on behalf of himself and a purported class of similarly situated persons as NYSE members, against the NYSE, its directors and The Goldman Sachs Group, Inc., in connection with the NYSE's proposed merger with Archipelago Holdings, Inc. ("Archipelago"). On May 13, 2005, William T. Caldwell, Morton B. Joselson

and John F. Horn filed a complaint in New York Supreme Court, on behalf of themselves and a purported class of similarly situated persons as NYSE members, against the NYSE, the NYSE's directors, The Goldman Sachs Group, Inc. and Archipelago. The lawsuits were consolidated under the caption In re New York Stock Exchange/Archipelago Merger Litigation, Index number 601646/05. The parties subsequently stipulated to dismiss Archipelago as a party from the litigation.

On September 27, 2005, William J. Higgins, William T. Caldwell, Morton B. Joselson, John F. Horn, Louis Erhard (who later withdrew), Robert Dill, Paul J. Mulcahy, Barbara Lynn DeCicco, Michael J. Quinn, Mark B. Grumet, and Anthony A. Saridakis filed a consolidated amended complaint under the above-referenced caption, on behalf of themselves and a purported class of similarly situated persons as NYSE members, against the NYSE, its directors and The Goldman Sachs Group, Inc. in connection with the merger. The consolidated amended complaint alleges that the NYSE and its directors breached their fiduciary duties of candor, care, loyalty, and good faith and unlawfully converted assets belonging to the NYSE members. The consolidated amended complaint also asserts one cause of action against The Goldman Sachs Group, Inc., alleging that it aided and abetted the breaches of fiduciary duties by the NYSE defendants. The consolidated amended complaint sought preliminary and permanent injunctive relief and compensatory damages. On November 15, 2005, the parties agreed to settle the litigation on terms that required the NYSE to provide the Court with a report by an independent financial expert on the fairness of the merger and required plaintiffs to dismiss the consolidated amended complaint with prejudice. On December 5, 2005, the Court issued a decision approving the settlement but reserved decision with respect to the amount of attorneys' fees and expenses that would be awarded to plaintiffs' attorneys. On February 21, 2006, the Court entered a Final Judgment and Order of Dismissal that required the NYSE to pay $9,095,511 for plaintiffs' attorneys' fees and expenses and dismissed the consolidated lawsuit with prejudice. An accrual for this amount was included in accrued expenses on the Statement of Financial Condition at December 31, 2005.

Compensation-Related Matters

In December 2003, the NYSE received a report from the law firm Winston & Strawn, which the NYSE had engaged to investigate and review certain matters relating to the compensation of its former Chairman and Chief Executive Officer ("CEO"), Richard A. Grasso, and the process by which that compensation was determined (the "Webb Report"). The NYSE provided the Webb Report to the United States Securities and Exchange Commission ("SEC") and the New York Attorney General's Office ("NYAG"), which commenced investigations relating to those matters in or about January 2004.

The Webb Report provided a detailed summary of, among other things, Mr. Grasso's compensation and benefits during the period in which he served as Chairman and CEO of the NYSE (1995-2003), including the various components thereof. On or about September 2, 2003, the NYSE transferred to Mr. Grasso $139,486,000, in respect of deferred compensation and benefits for that period. Previously, the NYSE had transferred to Mr. Grasso approximately $35 million in non-deferred compensation for that period.

On or about February 12, 2004, NYSE's then Interim Chairman, John S. Reed, sent Mr. Grasso a letter stating that the NYSE had determined that the compensation and benefits that Mr. Grasso received "were excessive and at unreasonable levels" and that, even granting Mr. Grasso the benefit of assumptions favorable to him, "were excessive by at least $120 million." In that letter, the NYSE demanded that

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 10—Litigation and Other Matters (Continued)

Mr. Grasso repay NYSE $120 million and reserved its rights to seek additional amounts beyond the $120 million demanded.

On May 24, 2004, the NYAG filed a lawsuit in New York Supreme Court against Mr. Grasso, former NYSE Director Kenneth Langone, and the NYSE. The complaint alleges six causes of action against Mr. Grasso, including breach of fiduciary duty under the New York Not-for-Profit Corporation Law ("N-PCL") and unjust enrichment. Among other things, the suit seeks imposition of a constructive trust for the NYSE's benefit on all compensation received by Mr. Grasso that was not reasonable and commensurate with services rendered, pursuant to provisions of the N-PCL "in an amount to be determined at trial"; a judgment directing Mr. Grasso to return payments made by the NYSE that were unlawful under the N-PCL "in an amount to be determined at trial"; and restitution of all amounts he received that lacked adequate Board approval because the Board's approval was based on inaccurate, incomplete or misleading information. The Attorney General further seeks a declaration by the court that any obligation to make future payments lacking the required board approval is void. In addition to the claims against Mr. Grasso, the complaint asserts a single cause of action against Mr. Langone for breach of his fiduciary duty under the N-PCL and a single cause of action against the NYSE seeking a declaratory judgment that the NYSE made unlawful, ultra vires payments to Mr. Grasso, and an injunction requiring the NYSE to adopt and implement safeguards to ensure that compensation paid in the future complies with the N-PCL. On July 23, 2004, the NYSE filed its answer to the complaint of the NYAG, in which it asserted several complete defenses.

The case is presently pending before New York Supreme Court Justice Charles E. Ramos. In his answer, Mr. Grasso denied the NYAG's allegations of wrongdoing and asserted various defenses. In addition, Mr. Grasso asserted claims against the NYSE and NYSE Chairman John Reed, including claims that the NYSE terminated Mr. Grasso without cause in September 2003 and breached his 1999 and 2003 employment agreements, and that the NYSE and Mr. Reed defamed him. Mr. Grasso has not claimed with specificity the amount of damages that he seeks in the litigation. In his pleadings, he seeks at least $50 million in compensatory damages for the NYSE's alleged breaches of the agreements; damages for alleged injury to his reputation and mental anguish and suffering; and punitive damages against Mr. Reed and the NYSE.

In or about March 2005, Mr. Grasso asserted third-party claims against former director Carl McCall for negligence, negligent misrepresentation and contribution. In August 2005, Mr. Grasso moved to dismiss four of the six causes of action alleged by the NYAG. The court has not rendered a decision on that motion. The parties currently are engaged in discovery. Trial currently is scheduled to commence on October 30, 2006.

The ultimate outcome of the above litigations cannot reasonably be determined at this time.

The Webb Report stated that the total amount of excessive compensation and benefits actually received by Mr. Grasso was in a range of approximately $113 million to $125 million (including both deferred and non-deferred compensation and benefits paid to Mr. Grasso). The specific amounts of compensation and benefits that should be repaid by Mr. Grasso will be the subject of expert testimony during the expert discovery phase of the litigation. If the NYAG prevails on all of his claims, the court will order Mr. Grasso to return to the NYSE portions of his compensation and benefits determined at trial to be unreasonable and declare that the alleged obligation of the NYSE to make further payments is void. Generally accepted accounting principles preclude the NYSE from accruing any recovery until the dispute between Mr. Grasso and the NYSE regarding compensation and benefits paid to him is resolved but

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 10—Litigation and Other Matters (Continued)

require the NYSE to accrue compensation expense related to him based upon the most recent employment agreement. At December 31, 2003, the NYSE accrued compensation expense amounting to $36 million related to Mr. Grasso. This accrual, which remains current, reflects management's interpretation of the provisions contained in the most recent employment agreement, which provides terms outlining certain payments to which Mr. Grasso could be entitled upon ceasing employment with the NYSE. Management is currently uncertain as to the timing of the resolution of the dispute. If significant changes relating to the ongoing dispute and the underlying assumptions used by management occur, those changes could lead to increases or decreases in the recorded liability as of December 31, 2005. These increases or decreases could be material to the results of operations and financial condition of the NYSE.

The NYSE is defending a number of other actions, the ultimate outcome of which cannot reasonably be determined at this time. In the opinion of management and legal counsel, the aggregate of all possible losses from all such other actions should not have a material adverse effect on the consolidated financial condition or results of operations of the NYSE.

Note 11—Retirement Benefits

The NYSE and SIAC maintain separate qualified defined benefit pension plans covering substantially all of their employees. Retirement benefits are derived from a formula, which is based on length of service and compensation. The NYSE and SIAC fund pension costs to the extent such costs may be deducted for income tax purposes. There were contributions made to the NYSE pension plan of $10.0 million in 2005 and $31.0 million in 2004. SIAC contributed $2.3 million in 2005 and $20.0 million in 2004 to its pension plan at this time. NYSE and SIAC intend to contribute the necessary amount to meet the funding requirements under the Internal Revenue Code of 1986, as amended, for 2006.

The NYSE bases its investment policy and objectives on a review of the actuarial and funding characteristics of the retirement plan, the demographic profile of plan participants, and the business and financial characteristics of the NYSE. Capital market risk/return opportunities and tradeoffs also are considered as part of the determination. The primary investment objective of the NYSE plan is to achieve a long-term rate of return that meets the actuarial funding requirements of the plan and maintains an asset level sufficient to meet all benefit obligations of the plan. Based on the plan's primary investment objective and on the NYSE's review of relevant plan characteristics, the NYSE has established 65% equity and 35% fixed income and cash equivalents allocation targets for the plan's investment program. The NYSE's pension plan weighted-average asset allocations at December 31, 2005 and 2004, by asset category are as follows:

Asset Category	2005		2004
Short-Term Investments	0.8	%	8.7	%
Equities	68.0	%	63.1	%
Fixed income	31.2	%	28.2	%

SIAC's investment policy is to actively manage certain asset classes where potential exists to outperform the broader market. SIAC's investment policy includes weighted average target asset

FIN-45

NYSE GROUP, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 11—Retirement Benefits (Continued)

allocations of 65% equity securities and 35% fixed income securities and cash equivalents. SIAC's pension plan weighted-average asset allocations at December 31, 2005 and 2004, by asset category are as follows:

Asset Category	2005		2004
Short-Term Investments	1	%	2	%
Equities	65	%	63	%
Fixed income	34	%	35	%

The NYSE and SIAC each also maintain separate Supplemental Executive Retirement Plan ("SERP"), a nonqualified plan, which provides supplemental retirement benefits for certain employees. To provide for the future payments of these benefits, the NYSE has purchased insurance on the lives of the participants through company-owned policies. At December 31, 2005 and 2004, the cash surrender value of such policies was $30.4 million and $28.8 million, respectively. SIAC maintains certain investments for the purpose of providing for future payments of SERP. These investments consist of equity and fixed income mutual funds. These are not considered funded assets under SFAS No. 87 "Employer's Accounting for Pensions" ("FAS 87"). Currently, the NYSE and SIAC do not anticipate additional funding of the nonqualified plan.

The costs of the plans in 2005 and 2004 have been determined in accordance with FAS 87. The measurement date for the plans is December 31, 2005 and 2004.

During 2005, the NYSE and SIAC announced that effective March 31, 2006 the future benefit accrual of all active participants in the pension and SERP plans will be frozen. Any pension benefits accrued by current employees through March 31, 2006 will be frozen and accrued benefits will be paid under the assets available. Any SERP benefits accrued by current employees through March 31, 2006 will be frozen and accrued benefits will be paid utilizing assets available at the time of payments. Effective April 1, 2006, NYSE and SIAC employees will be eligible to receive benefits from a new employer-funded defined contribution Retirement Accumulation Plan.

To develop the expected long-term rate of return on assets assumption, the NYSE considered the historical returns and the future expectations for returns for each asset class as well as the target asset allocation of the pension portfolio. The assumed discount rate reflects the market rates for high-quality corporate bonds currently available. The discount rate was determined by considering the average of pension yield curves constructed on a large population of high quality corporate bonds. The resulting discount rates reflect the matching of plan liability cash flows to the yield curves.

Pursuant to the provisions of FAS 87 related to the SERP and pension plans, an intangible asset and adjustment to accumulated other comprehensive income to recognize the minimum pension liability were recorded. As of December 31, 2005, the intangible asset was adjusted to zero and minimum pension liability was adjusted to $11.8 million (net of tax and minority interest of $7.6 million). During 2004, the intangible asset and minimum pension liability were adjusted to $2.7 million and $5.8 million (net of tax and minority interest of $5.9 million), respectively.

Note 12—Other Employee Benefit Plans

In addition to providing pension benefits, the NYSE and SIAC maintain defined benefit plans to provide certain health care and life insurance benefits (the "Plans") for eligible retired employees. These

Note 12—Other Employee Benefit Plans (Continued)

Plans, which may be modified in accordance with their terms, cover substantially all employees. These Plans are measured on December 31 annually.

The net periodic postretirement benefit cost for the NYSE was $14.6 million and $8.8 million for years ended December 31, 2005 and 2004, respectively. SIAC's benefit cost was $7.8 million in 2005 and $6.2 million in 2004. The Plans are unfunded. Currently, management does not expect to fund the Plans.

For measurement purposes, the NYSE and SIAC assumed a 10% annual rate of increase in the per capita cost of covered health care benefits in 2005 which will decrease on a graduated basis to 5% in the year 2014 and thereafter.

During 2005, the NYSE and SIAC announced that changes would be made to this plan, including the underlying plan design and contribution strategy. These changes became effective in January, 2006. Plan amendments resulted in a reduction of $25.9 million of benefit obligation as of December 31, 2005.

In May 2004, the FASB issued FASB Staff Position No.106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003 ("FSP 106-2") in response to a new law regarding prescription drug benefits under Medicare as well as a federal subsidy to sponsors of retiree healthcare benefit plans. FSP 106-2 was reflected in accumulated postretirement medical benefit obligations as of January 1, 2004 assuming that the NYSE will continue to provide a prescription drug benefit to retirees that is at least actuarially equivalent to Medicare Part D and the NYSE will receive the federal subsidy. The accumulated postretirement benefit obligation (APBO) as of January 1, 2004 decreased by $10.4 million and the net periodic postretirement medical cost for 2005 was reduced by approximately $3.2 million.

The NYSE also maintains savings plans for which most employees are eligible to contribute a part of their salary within legal limits. The NYSE will match an amount equal to 100% of the first 6% of eligible contributions. The NYSE also provides benefits under a Supplemental Executive Savings Plan to which eligible employees may also contribute and receive an appropriate company match. SIAC maintains similar though separate plans. Savings plans expense was $20.3 million, $18.8 million and $16.9 million for the years ended December 31, 2005, 2004 and 2003, respectively. Included in accrued employee benefits payable was $65.5 million and $63.4 million at December 31, 2005 and 2004, respectively related to these plans.

The NYSE has a Capital Accumulation Plan (CAP) for designated senior executives. During 2004, this plan terminated and no further awards will be granted. Existing awards will continue to vest. Historically under the CAP, each year, participating executives were credited with an amount based upon a percentage of their annual Incentive Compensation Plan award. These awards vest, for each executive, between the ages of 55 and 65 (depending on the date of grant awarded), and are transferred into a separately managed account as they vest. Unvested CAP amounts earn interest based upon the 10-year Treasury Bond rate as of December 31 of the prior year. Participants may elect to receive their vested account balances in a lump sum distribution or annual installments following termination of employment. The total amount of the awards in 2003 was $1.1 million. Liabilities associated with these plans were $10.0 million at December 31, 2005 and $14.6 million at December 31, 2004, respectively, related to this plan. Awards are included as compensation expense in the year awarded and any related interest is included in compensation expense in the year earned.

The NYSE has accumulated excess activity assessment fees, which amount to approximately $15.1 million as December 31, 2005. Due to the uncertainty of the claim on the excess activity assessment fees, management has recorded a liability for the full amount of the excess because it believes that it is probable that there will be an arrangement pursuant to which the entire amount will be used for a public purpose.

In the normal course of business, NYSE may enter into contracts that require it to make certain representations and warranties and which provide for general indemnifications. Based upon past experience, the NYSE expects the risk of loss under these indemnification provisions to be remote. However, given that these would involve future claims against NYSE that have not yet been made, NYSE's

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Archipelago Holdings, Inc.

We have audited management's assessment, included in the accompanying "Management's Report on Internal Control Over Financial Reporting" that Archipelago Holdings, Inc. (the "Company") maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Archipelago Holdings, Inc.'s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As indicated in the accompanying "Management's Report on Internal Control over Financial Reporting" management's assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of PCX Holdings, Inc. and its wholly owned subsidiaries ("PCX") which is included in the 2005 consolidated financial statements of Archipelago Holdings, Inc. and constituted $115.3 million and $30.9 million of total and net assets, respectively, as of December 31, 2005 and $16.8 million and $2.6 million of revenues and net income, respectively, for the year then ended. Management did not assess the effectiveness of internal controls over financial reporting of PCX Holdings, Inc. and its wholly owned subsidiaries as the Company did not complete the acquisition of PCX until September 2005. Our audit of internal control over financial reporting of Archipelago Holdings, Inc. also did not include an evaluation of the internal control over financial reporting of PCX.

In our opinion, management's assessment that Archipelago Holdings, Inc. maintained effective internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Archipelago Holdings Inc. maintained, in all material

FIN-56

respects, effective internal control over financial reporting as of December 31, 2005, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of financial condition of Archipelago Holdings, Inc. as of December 31, 2005 and 2004, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2005 of Archipelago Holdings, Inc. and our report dated February 10, 2006 expressed an unqualified opinion thereon.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Archipelago Holdings, Inc. ("Archipelago" or the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting of the Company. Archipelago's internal control over financial reporting is a process designed under the supervision of its chief executive and chief financial officers to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Archipelago's financial statements for external reporting purposes in accordance with United States generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Management assessed the effectiveness of its internal control over financial reporting as of December 31, 2005, based on criteria set forth in the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Although there are inherent limitations in the effectiveness of any system of internal control over financial reporting, based on its assessment, management concluded that Archipelago maintained effective internal control over financial reporting as of December 31, 2005.

Management's assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of PCX Holdings, Inc. and Subsidiaries ("PCX"), which are included in the consolidated financial statements of Archipelago as of and for the year December 31, 2005. PCX constituted $115.3 million and $30.9 million of total assets and net assets, respectively, as of December 31, 2005, and $16.8 million and $4.5 million of total revenues and operating income, respectively, for the year then ended. Management did not assess the effectiveness of internal controls over financial reporting of PCX because Archipelago did not complete its acquisition of PCX until September26, 2005.

Archipelago's management assessment of the effectiveness of its internal control over financial reporting as of December 31, 2005 has been audited by Ernst & Young, LLP, an independent registered public accounting firm, as stated in their report which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Archipelago Holdings, Inc.

We have audited the accompanying consolidated statements of financial condition of Archipelago Holdings, Inc. (the "Company") as of December 31, 2005 and 2004, and the related consolidated statements of operations, changes in stockholders' equity, and cash flows for the years ended December 31, 2005, 2004 and 2003. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2005 and 2004, and the consolidated results of their operations and their cash flows for the years ended December 31, 2005, 2004 and 2003 in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company's internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 10, 2006 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Organization and Basis of Presentation

Organization

Archipelago Holdings, Inc. ("Archipelago") operates the Archipelago Exchange, or ArcaEx® ("ArcaEx"), the first open all-electronic stock market in the United States of America for trading equity securities listed with the New York Stock Exchange ("NYSE"), Nasdaq, American Stock Exchange ("AMEX") and Pacific Exchange, as well as exchange-traded funds (ETFs) and other exchange-listed securities.

Following the September 26, 2005 acquisition of PCX Holdings, Inc. and its subsidiaries ("PCX Holdings"), Archipelago also operates the Pacific Exchange, Inc. (the "Pacific Exchange"), an exchange for trading equity options listed on national markets and exchanges including the facilities, technology, systems and regulatory surveillance and compliance services required for the operation of a marketplace for trading options. Through the Pacific Exchange, Archipelago also provides self-regulatory services, including regulatory and market management services for options and equity trading.

Through certain subsidiaries, Archipelago also provides broker execution services to institutions for orders involving Nasdaq and listed securities, as well as introducing broker services for ArcaEx to broker-dealers that do not hold an equity trading permit ("ETP").

Archipelago Holdings, L.L.C. ("Holdings LLC"), a Delaware limited liability company and the predecessor to Archipelago, was organized in January 1999. In July 2000, Holdings LLC entered into a facility services agreement with the Pacific Exchange which allowed it to establish and operate ArcaEx. The Securities and Exchange Commission's ("SEC") approval of ArcaEx was announced in October 2001 and ArcaEx began trading operations for listed securities in March 2002 and for over-the-counter securities in April 2003.

On August 11, 2004, Holdings LLC converted to a Delaware corporation, Archipelago Holdings, Inc. This document refers to Archipelago Holdings, Inc. and, prior to its conversion to a Delaware corporation, Holdings LLC, as "Archipelago". On August 19, 2004, Archipelago completed an initial public offering ("IPO") of its common stock. See the discussion below of the "Conversion Transaction" and the "Initial Public Offering."

On March 7, 2006, Archipelago became a wholly owned subsidiary of NYSE Group and its common stock delisted from the Pacific Exchange. See Note 3, Merger with the New York Stock Exchange, Inc.

Conversion Transaction

On August 11, 2004, prior to the consummation of the IPO, Holdings LLC converted from a Delaware limited liability company to a Delaware corporation, Archipelago Holdings, Inc. As a limited liability company, all income taxes were paid by the members of Holdings LLC. As a corporation, Archipelago is responsible for the payment of all federal and state corporate income taxes.

As a result of the reorganization of Holdings LLC from a Delaware limited liability company into a Delaware corporation, the members of Holdings LLC received 0.222222 shares of common stock of Archipelago for each of their membership interests held by such member in Holdings LLC, which corresponds to a 4.5-for-1 reverse stock split. The weighted average number of shares used in the basic and diluted earnings per share computations gives retroactive effect to the 4.5-for-1 reverse stock split.

As approved by Archipelago's board of managers on July 16, 2004, Archipelago made a $24.6 million cash distribution to the members of Holdings LLC immediately prior to the conversion transaction. The

FIN-64

ARCHIPELAGO HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 1—Organization and Basis of Presentation (Continued)

cash distribution permitted the members to pay the taxes that the members owe for their share of the Archipelago's profits in 2004 as a limited liability company through the date of the conversion transaction, calculated primarily based on the highest federal and state income tax rate applicable for the tax withholding purposes to an individual.

Initial Public Offering

On August 19, 2004, Archipelago completed the IPO of its common stock as a result of which Archipelago sold 6,325,000 shares of common stock at $11.50 per share. Archipelago received net proceeds of $67.6 million and incurred approximately $6.8 million in expenses in connection with the IPO. In addition, 6,325,000 shares of common stock were sold in the IPO by certain selling stockholders of Archipelago, for which Archipelago received no proceeds.

Basis of Presentation

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of Archipelago and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

In connection with the acquisition of PCX Holdings, the SEC entered an order under which Archipelago undertook to divest its wholly owned subsidiary, Wave Securities, L.L.C ("Wave"). The results of operations and financial position of Wave are presented as discontinued operations in the accompanying consolidated financial statements. All historical periods presented have been restated to reflect such presentation.

Included in other assets in the Archipelago's consolidated statement of financial condition as of December 31, 2005 is a 20 percent investment in The Options Clearing Corporation ("OCC"). This investment is carried at its $0.3 million cost. The related shares are subject to certain restrictions. In addition, management does not exercise significant influence over the operating and financial policies of OCC.

Certain reclassifications have been made to prior years in order to conform to the current year's presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that the estimates utilized in preparing its consolidated financial statements are reasonable. Actual results could differ from these estimates.

Note 2—Summary of Significant Accounting Policies

Revenue Recognition

Transaction fees are earned on a per trade basis, based on shares transacted, and are recognized as transactions occur. For each transaction executed, there is an associated liquidity payment or routing charge paid. Pursuant to Emerging Issues Task Force ("EITF") Issue No. 99-19, "Reporting Revenue Gross as a Principal versus Net as an Agent" ("EITF 99-19"), Archipelago records such expenses as liquidity payments or routing charges in the consolidated statements of operations.

Market data fees are earned on the sale of transaction market data. This revenue is recorded net of amounts due under revenue sharing arrangements with market participants, based on the criteria provided by EITF 99-19. Market data fees are recognized as transactions occur.

Listing fees are earned from companies and index providers that list on the Pacific Exchange as a trading venue for their equity securities, exchange-traded funds and other structured products. Archipelago recognizes initial listing fees and additional share listing fees ratably over a five-year estimated service period. Annual listing fees are recognized ratably over the related twelve-month period.

Other revenues primarily consist of regulatory and registration fees including agent annual registration and new application and transfer fees from parties that have equities or options trading privileges on the Pacific Exchange. Regulatory and registration fees are billed and collected by the National Association of Securities Dealers (the "NASD"). The annual registration fee is billed annually in advance and remitted to Archipelago before the start of the effective year. Archipelago recognizes the annual registration fee ratably over the related twelve-month period. New registration and transfer application fees are remitted monthly to Archipelago and recognized in the year received.

Activity Assessment Fees and Section 31 Fees

Archipelago pays SEC fees pursuant to Section 31 of the Securities Exchange Act of 1934. These fees are designed to recover costs incurred by the government for the supervision and regulation of securities markets and securities professionals. Archipelago, in turn, collects activity assessment fees from ETP and OTP holders trading on ArcaEx and the Pacific Exchange, respectively, and pays Section 31 fees to the SEC based on fee schedules determined by the SEC. Fees received are included in cash and cash equivalents at the time of receipt, and, as required by law, the amount due to the SEC is recorded as an accrued liability and remitted semiannually.

Following the September 26, 2005 acquisition of PCX Holdings, Archipelago records activity assessment fee revenue and Section 31 fees expense gross on its consolidated statement of operations as Archipelago bears the credit risk associated with the collection of these fees, while maintaining similar treatment within the consolidated statement of financial condition. Activity assessment fee revenue and Section 31 fee expense have no impact on Archipelago's consolidated statement of operations.

Cash and Cash Equivalents

Archipelago considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

FIN-66

ARCHIPELAGO HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Summary of Significant Accounting Policies (Continued)

Provision for Doubtful Accounts

Archipelago maintains an allowance for doubtful accounts based upon the estimated collectibility of accounts receivable. Archipelago recorded provisions (additions) to the allowance of approximately $0.8 million and $0.0 million, and write-offs (deductions) against the allowance of approximately $3.1 million and $1.3 million for the years ended December 31, 2005 and 2004, respectively. Additions to (reductions of) the allowance are charged to (reversed against) bad debt expense, which is included in clearance, brokerage and other transaction expenses in the consolidated statements of operations.

Fixed Assets

Fixed assets consist of computer hardware and software, furniture, equipment (including assets under capital leases) and leasehold improvements. All fixed assets are carried at cost and are depreciated on a straight-line basis over their estimated useful lives of three to ten years. Leasehold improvements are amortized over the shorter of the life of the lease or their estimated useful life. Gains or losses related to retirements or disposition of fixed assets are recognized in the period incurred.

In accordance with the provisions of Statement of Position ("SOP") 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use", Archipelago capitalizes qualifying software costs incurred during the application development stage, which includes design, coding, installation and testing activities. Amortization of capitalized software development costs is computed on a straight-line basis over the software's estimated useful life, generally three years.

Archipelago performs reviews for the impairment of fixed assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Goodwill and Other Intangible Assets

Archipelago reviews the carrying value of goodwill for impairment on a periodic basis and at least annually based upon estimated fair value of Archipelago's reporting units. Using an independent valuation specialist, Archipelago, on an annual basis, estimates fair value by using a discounted cash flow model. Should the review indicate that goodwill is impaired, Archipelago's goodwill would be reduced by the difference between the carrying value of goodwill and its fair value.

Archipelago reviews the useful life of its indefinite-lived intangible asset to determine whether events or circumstances continue to support the indefinite useful life. In addition, the carrying value of Archipelago's intangible assets is reviewed by Archipelago on at least an annual basis for impairment based upon the estimated fair value of the asset calculated by an independent valuation specialist.

Archipelago performed its annual impairment tests as of December 31, 2004 and 2005, which indicated that no impairment charge was required for goodwill or intangible assets.

Estimated Fair Value of Financial Instruments

Statement of Financial Accounting Standard ("SFAS") No. 107, Disclosure about Fair Value of Financial Instruments, requires the disclosure of the fair value of financial instruments, including assets and liabilities recognized in the consolidated statements of financial condition. Management estimates that the fair value of financial instruments recognized in the consolidated statements of financial condition (including cash and cash equivalents, receivables, payables and accrued expenses) approximates their

FIN-67

ARCHIPELAGO HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Summary of Significant Accounting Policies (Continued)

carrying value, as such financial instruments are short-term in nature, bear interest at current market rates or are subject to repricing monthly.

Income Taxes

Archipelago had elected to be treated as a partnership for federal, state and local income tax purposes prior to its reorganization on August 11, 2004. Accordingly, all items of income, expense, gain and loss of Archipelago prior to August 12, 2004 were generally reportable on the tax returns of the members of Holdings LLC. Therefore, Archipelago had no net loss carryforwards as of the date of reorganization. On August 11, 2004, Archipelago converted to a Delaware corporation and has since then been subject to income taxes.

Archipelago records income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. A valuation allowance is recorded against deferred tax assets if it is more likely than not that such assets will not be realized.

Marketing and Promotion

Marketing and promotion costs consist of advertising costs, promotional items, trade shows, and selling expenses. Advertising costs include certain costs of production, which are expensed at the time of first showing. The costs of communicating advertising are expensed over the period of the communication.

Stock-Based Compensation

Archipelago accounts for stock option grants to employees in accordance with Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees", and, accordingly, recognizes compensation expense using the intrinsic value method. Under the intrinsic value method, stock-based compensation, if any, is measured as the excess of the estimated fair value of Archipelago's stock over the option exercise price.

Archipelago adopted the disclosure provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" and SFAS No. 148, "Accounting for Stock-Based Compensation—Transition and Disclosure." Had compensation expense for Archipelago's stock option plans been determined based upon

fair value consistent with SFAS No. 123, Archipelago's net income and earnings per share would have been changed to the following pro forma amounts (in thousands, except per share data):

		Year ended December 31,
		2005		2004		2003
Net income attributable to common stockholders, as reported		$	16,319	$	59,321	$	1,773
Add: Stock-based employee compensation cost included in net income			6,390		151		334
Deduct: Stock-based employee compensation cost determined under the fair value based method for all awards, net of related tax effects of $5,788, $739, and $919			7,832		1,041		1,379

Net income attributable to common stockholders, pro forma		$	14,877	$	58,431	$	728

Earnings per share:
	Basic, as reported	$	0.35	$	1.47	$	0.05
	Basic, pro forma	$	0.32	$	1.45	$	0.02
	Diluted, as reported	$	0.34	$	1.38	$	0.05
	Diluted, pro forma	$	0.31	$	1.36	$	0.02

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

	Year ended December 31,
	2005		2004		2003
Dividend yield	0		0		0
Expected volatility	30.0	%	30.0	%	30.0	%
Risk-free interest rate	4.5	%	4.0	%	3.8	%
Expected life (in years)	7		7		7

The Black-Scholes option pricing model was developed for use in estimating the value of traded options that have no vesting restrictions and are fully transferable. In addition, option pricing models require the input of highly subjective assumptions. Because Archipelago's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the estimate, in management's opinion, the existing valuation models may not provide a reliable measure of the fair value of Archipelago's employee stock options.

The above pro forma information gives effect to Archipelago's conversion into a Delaware corporation as if it occurred at the beginning of the periods presented. In addition, the pro forma information was tax effected at combined Federal and State rates of 40.0%, 41.5% and 42.5% for the years ended December 31, 2003, 2004 and 2005, respectively.

In December 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No.123(R) (revised 2004), "Share- Based Payment", requiring that compensation cost associated with share-based payment transactions be recognized in financial statements. Archipelago adopted SFAS No. 123(R) on January 1, 2006 using the modified-prospective method. For the year ending December 31, 2006, management anticipates that Archipelago will recognize a pre-tax expense of approximately $2.0 million in connection with Archipelago share-based payment transactions recorded under SFAS No.123 (R).

Note 3—Merger with New York Stock Exchange, Inc.

On April 20, 2005, Archipelago entered into a definitive merger agreement with the New York Stock Exchange, Inc., a New York Type A not-for-profit corporation (the "NYSE"), pursuant to which Archipelago and the NYSE agreed to combine their businesses and become wholly owned subsidiaries of NYSE Group, Inc., a newly created, for-profit holding company (the "merger").

The merger closed on March 7, 2006. As of that date, Archipelago became a wholly owned subsidiary of NYSE Group and its common stock delisted from the Pacific Exchange. The NYSE Group's common stock is listed on the New York Stock Exchange and is traded under the symbol "NYX".

In the merger of Archipelago and a wholly owned subsidiary of NYSE Group, in which Archipelago was the surviving entity: (i) each share of the issued and outstanding shares of Archipelago common stock converted automatically into the right to receive one share of NYSE Group common stock; (ii) all outstanding stock options of Archipelago, whether vested or unvested, converted into options to purchase an equivalent number of shares of NYSE Group common stock; and (iii) all outstanding restricted stock units of Archipelago converted into an equal number of restricted stock units of NYSE Group common stock. The aggregate number of shares (including shares underlying stock options and restricted stock units) received by Archipelago's stockholders equaled 30% of the issued and outstanding shares of NYSE Group common stock at the closing of the merger, on a diluted basis.

Each NYSE member was entitled to receive in exchange for its NYSE membership, $300,000 in cash, plus a pro rata portion of the aggregate number of shares of NYSE Group Common Stock issued to all of the NYSE members in the merger. Each NYSE member had the opportunity to make either a cash election to increase the cash portion (and decrease the stock portion) of their merger consideration, or a stock election to increase the stock portion (and decrease the cash portion) of their merger consideration. These elections were subject to certain proration. The aggregate number of shares of NYSE Group Common Stock issued to all of the NYSE members in the merger, together with the aggregate number of shares reserved for issuance to NYSE employees, equaled 70% of the NYSE Group common stock issued and outstanding at the closing of the NYSE transaction, on a diluted basis.

The parties expect that the combined businesses will bring together the strength of NYSE's auction market and the speed and innovation of Archipelago as well as its technology and management. The parties believe this combination will create a strong and dynamic enterprise with diverse products that will be well positioned to compete in the industry and possess enhanced growth potential.

In April 2005, Archipelago entered into a letter agreement with a related party stockholder under which the stockholder agreed to perform certain services in relation to the merger of Archipelago and the NYSE which included facilitating discussions between the parties and providing certain valuation analysis. Archipelago agreed to pay the related party stockholder a transaction fee of $3.5 million (plus out-of-pocket expenses in an amount not to exceed $50,000) in cash upon consummation of the merger. Archipelago has not made any payments under this agreement as of December 31, 2005.

Note 4—PCX Holdings, Inc. Acquisition

On September 26, 2005, Archipelago completed the acquisition of PCX Holdings for a total purchase price of approximately $94.0 million consisting of a $90.9 million cash payment to PCX Holdings stockholders and certain employees of PCX Holdings and its subsidiaries, and approximately $3.1 million of direct costs incurred by Archipelago as part of this acquisition (the "PCX Holdings acquisition"). The $90.9 million cash payment represented the total dollar value of 1,645,415 shares of Archipelago common

stock held by PCX Holdings at the time of the closing, or $66.3 million (calculated based on the average closing price of Archipelago's stock on ArcaEx for the ten trading days prior to the PCX Holdings acquisition), plus $24.6 million.

PCX Holdings operates an exchange for trading options as well as provides self regulatory services, including regulatory and market management services, for options and equity trading. The PCX Holdings acquisition will enable Archipelago to offer all-electronic trading of equity securities as well as equity options, and to expand and diversify the Archipelago's business lines and products.

Even though the PCX Holdings acquisition was consummated on September 26, 2005, for financial reporting purposes management deemed the assets and liabilities of PCX Holdings as of September 30, 2005 to be the basis for allocation of the purchase price. As such, the assets and liabilities of PCX Holdings have been included in Archipelago's consolidated statement of financial condition as of September 30, 2005. However, the results of operations of PCX Holdings have been included in Archipelago's results of operations since October 1, 2005. The results of operations of PCX Holdings for the four-day period ended September 30, 2005 were not material.

The purchase price was allocated to those assets acquired and liabilities assumed based on the estimated fair value of PCX Holdings' net assets as of September 30, 2005. The following is a summary of the preliminary allocation of the purchase price in the PCX Holdings acquisition (dollars in thousands):

Purchase price	$	90,863
Acquisition costs		3,167

Total purchase price	$	94,030

Historical cost of net assets acquired	$	54,316
Reversal of deferred revenues		20,431
Write-down of fixed assets		(10,673	)
National securities exchange registration		17,728
Liabilities for exit and termination costs		(11,480	)
Deferred tax impact of purchase accounting adjustments		23,708

Total purchase price	$	94,030

Liabilities for exit and termination costs are primarily associated with employee terminations, including accrued severance benefits and costs related to change in control provisions of certain PCX Holdings employment contracts. In 2005, Archipelago paid an aggregate of $5.9 million in connection with these change in control provisions and severance benefits. Based upon current severance dates, Archipelago expects to pay the $5.6 million balance by September 30, 2006.

The allocation of the purchase price to PCX Holdings' assets and liabilities are only preliminary allocations based on estimates of fair values and will change when estimates are finalized. Therefore, the information above is subject to change pending the final allocation of purchase price.

Note 5—Discontinued Operations

On September 22, 2005, the SEC entered an order granting approval of the proposed rule change to amend the certificate of incorporation of PCX Holdings, Pacific Exchange Rules, and the bylaws of Archipelago in relation to the PCX Holdings acquisition. Under the SEC order, Archipelago undertook to divest Wave, its wholly owned subsidiary providing agency brokerage services for institutional customers seeking to access ArcaEx and other U.S. market centers electronically.

On January 23, 2006, Archipelago entered into a definitive agreement to sell Wave to a related party stockholder. On March 3, 2006, Archipelago completed the sale of Wave.

Goodwill

In March 2002, Archipelago acquired REDIBook in a transaction accounted for as a purchase business combination. Approximately $20.8 million of the $150.5 million purchase price was assigned to the net tangible and intangible assets acquired, with the remaining value of $129.7 million ascribed to goodwill. In August 2004, Archipelago issued contingent consideration to former REDIBook members in the form of 192,194 shares of Archipelago's common stock valued at $11.50 per share and recorded $2.2 million of additional goodwill.

In May 2001, Archipelago acquired the right to operate as the exclusive equity trading facility of PCX Equities including the rights to certain revenue streams comprised primarily of transaction fees, market data fees, and listing fees, for an aggregate consideration of $90.0 million.

In September 2005, Archipelago acquired PCX Holdings and its subsidiaries, including PCX Equities. As part of the preliminary allocation of the purchase price in the PCX Holdings acquisition, Archipelago valued the eligibility to earn market data fees related to the PCX Holdings' option trading business at $17.7 million.

The national securities exchange registration allows Archipelago to (i) generate revenues from market data fees (both from equity and option trading activities) and listing fees, and (ii) to reduce its costs since clearing charges are not incurred for trades matched internally on ArcaEx.

Archipelago determined that the national securities exchange registration has an indefinite life and, as such, it is not subject to amortization.

Note 9—Stockholders' Equity

Common Stock

Prior to its reorganization from a Delaware limited liability company to a Delaware corporation on August 11, 2004, Archipelago had three classes of common shares outstanding: Class A, Class B and Class C. The common shares ranked pari passu with regards to liquidation and distribution. Class A shares had voting rights, while Class B and C shares had no voting rights. As part of the conversion transaction, all of the Class A, Class B and Class C shares were converted to common stock.

Redeemable Convertible Preferred Shares

On November 12, 2003, Archipelago issued 16,793,637 Class A Preferred Shares, which were a newly-created class of voting shares, at $2.98 per share, for total consideration of $50,000,000. Archipelago incurred approximately $1.6 million in transaction costs in conjunction with this issuance. The Class A Preferred Shares converted automatically into 4,449,268 shares of common stock upon consummation of Archipelago's IPO in August 2004. Included in this conversion was the issuance of 717,349 shares of common stock attributable to a beneficial conversion feature included in the previously issued redeemable preferred interest. The $9.6 million intrinsic value of such shares was treated as a deemed dividend on convertible preferred shares, which was reported after net income to reach net income attributable to common stockholders in the consolidated statement of operations for the year ended December 31, 2004.

Common Stock Held in Treasury

As of December 31, 2005, Archipelago held 1,801,921 million shares of its common stock in treasury, including 1,645,415 shares repurchased as part of the PCX Holdings acquisition.

Employee and Non Employee Director Stock and Benefit Plans

Archipelago has three long-term incentive plans (the "Plans") that provide for the granting of stock options and restricted stock units to officers, key employees and non-employee directors. The objectives of the Plans include attracting and retaining the best personnel, providing for additional performance incentives, and promoting the success of Archipelago by providing employees the opportunity to acquire common stock. The stock options and restricted stock units ("RSUs") granted under the Plans generally vest over four years. Stock option awards have a term of ten years.

The fair market value at the date of grant of the RSUs is amortized over the vesting period using the straight line method. For the year ended December 31, 2005, Archipelago recorded stock-based compensation expense of $11.1 million, including $3.6 million in relation to the regular vesting of RSUs (which is included in other employee compensation and benefits in the consolidated statement of operations) and $7.5 million in connection with the acceleration of vesting of certain RSUs (which is included in NYSE merger and related executive compensation in the consolidated statement of operations).

On December 30, 2005, Archipelago entered into agreements with each of its executive officers that accelerated, among other things, vesting of 401,475 RSUs that would have occurred in 2006 after the completion of the merger or, in the case of one executive, upon the sale of Wave.

As part of their compensation, Archipelago's non-employee directors received an annual RSU grant valued at $75,000 based upon the fair market of Archipelago's share of common stock on the date of grant. In addition, non-employee directors were permitted to elect to take all or a portion of their $75,000 cash retainer in RSUs, calculated by taking 110% of the $75,000 cash retainer, or $82,500, divided by the fair market of Archipelago's share of common stock on the date of grant. For the years ended December 31, 2005 and 2004, Archipelago granted 33,586 and 47,076 RSUs to its non-employee directors, respectively.

As of December 31, 2005, Archipelago had approximately $29.9 million of net operating losses for Federal and State tax purposes ("NOL"), which will begin to expire in 2021. A full valuation allowance was recorded against approximately $1.3 million tax effect of certain NOLs as it appears more likely than not that the corresponding asset will not be realized due to certain tax limitations. There is no valuation allowance recorded against any of the remaining deferred tax assets based on management's belief that it is more likely than not that such assets will be realized. Archipelago does not have any deferred tax assets related to Holdings LLC's net operating losses, as those losses were incurred when Archipelago was treated as a partnership for federal income tax purposes.

Note 12—Income Taxes (Continued)

The effective tax rate varied from the U.S. Federal statutory income tax rate due to the following:

	Year ended December 31,
	2005		2004		2003
Federal statutory rate	35.0	%	35.0	%	35.0	%
State, net of Federal tax benefit	5.3		1.8		—

Other	(5.2	)	0.4		—

Effective tax rate	42.8	%	8.4	%	—	%

(1): Archipelago recognized a $3.8 million net deferred tax asset for temporary differences when Holdings LLC converted into a Delaware corporation on August 11, 2004. The corresponding deferred tax benefit lowered Archipelago's effective tax rate for the year ended December 31, 2004.
(2): For the income earned from the date of the conversion to a Delaware corporation through December 31, 2004, Archipelago provided for income taxes based on a 41.5% combined tax rate. Prior to August 12, 2004, all income taxes were paid by Holdings LLC's former members.

Note 13—Segment Reporting

Prior to the PCX Holdings acquisition, Archipelago operated in two reportable segments: Transaction Execution Services and Agency Brokerage Services.

Transaction Execution Services consisted primarily of transaction execution services, market data services on a real-time or summary basis and, through the Archipelago's alliance with the Pacific Exchange, a trading venue for issuers of equity securities, exchange traded funds and structured products. Under Pacific Exchange rules, issuers are listed on the Pacific Exchange for trading on ArcaEx. The customers in this segment are required to hold an ETP or be a broker-dealer introduced to ArcaEx by an ETP. An ETP holder must be a broker-dealer.

Agency Brokerage Services were provided through Wave and consisted of order execution services, on an agency basis, for orders received from institutions involving primarily Nasdaq and listed securities. This segment provided institutions that are not ETP holders or are not sponsored by ETP holders access to all U.S. Nasdaq and exchange-listed securities markets through ArcaEx. Because Wave's operations are presented as discontinued, Archipelago is no longer required to disclose the information required by SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information".

Following the PCX Holdings acquisition, Archipelago operates in the following two reportable segments: ArcaEx Equities and ArcaEx Options.

ArcaEx Equities consists primarily of the reportable segment formerly named Transaction Execution Services.

ArcaEx Options consists primarily of transaction execution services, market data services on a real-time or summary basis and a trading venue for issuers of option products. The customers in this

Note 13—Segment Reporting (Continued)

segment are required to hold an Option Trading Permit ("OTP"). An OTP holder must be a broker-dealer or associated with a broker dealer.

Revenues are generated primarily in the United States of America. Revenues derived from one stockholder/former member of Holdings LLC and its affiliates represented approximately 9.6%, 10.2% and 14.2% of the revenues from continuing operations for the years ended December 31, 2005, 2004 and 2003, respectively. All of Archipelago's long lived assets are located in the United States of America.

Summarized financial information concerning Archipelago's reportable segments is as follows (in thousands):

	ArcaEx Equities		ArcaEx Options		Eliminations			Consolidated
Year ended December 31, 2005
Revenues	$	525,195	$	16,797	$	(648	)	$	541,344
Depreciation and amortization		19,896		1,735		—			21,631
Expenses		512,284		12,311		(648	)		523,947

Identifiable assets of continuing operations (as of December 31)		462,350		115,289		(12,002	)		565,637

Note 14—Commitments and Contingencies

In the normal course of conducting its business, Archipelago has been involved in various legal proceedings. In the opinion of management, after consultation with legal counsel, the ultimate outcome of pending litigation matters will not have a material adverse effect on the financial condition or results of operations of Archipelago.

Archipelago leases office space under non-cancelable operating leases and certain computer equipment under capital leases. The future minimum commitments under these non-cancelable leases at December 31, 2005 were as follows (in thousands):

Year ending December 31,
2006	$	9,352
2007		8,093
2008		7,016
2009		4,967
Thereafter		13,779

Net minimum lease payments	$	43,207

Total rent expense, including real estate taxes and common area maintenance, was approximately $7.1 million, $4.6 million and $4.2 million for the years ended December 31, 2005, 2004 and 2003, respectively. The rent expense is recorded net of sublease payments received of approximately $0.2 million and $0.5 million for the years ended December 31, 2005 and 2004, respectively.

Archipelago applies the provisions of the Financial Accounting Standards Board's Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees of Indebtedness of Others," which provides accounting and disclosure requirements for certain guarantees. Archipelago has

FIN-84

ARCHIPELAGO HOLDINGS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 14—Commitments and Contingencies (Continued)

agreed to indemnify its clearing brokers for losses that they may sustain from customer accounts introduced by Archipelago. However, Archipelago has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. As such, Archipelago has not recorded any liability related to this indemnification. Archipelago is unable to quantify the potential exposure related to the indemnification as it constantly fluctuates based on the number and size of the unsettled transactions outstanding and the difference between the contractual trade price and the current fair value of the stock underlying the unsettled transactions.

Note 15—Net Capital Requirements

Wave, Archipelago Securities, L.L.C. ("ARCAS"), ATSI and Archipelago Brokerage Services, LLC ("ABS") are registered broker-dealers and are subject to net capital requirements under SEC Rule 15c3-1. Wave, ATSI and ABS compute their net capital using the basic method. Under this method, these subsidiaries must maintain minimum net capital (as defined) and the ratio of aggregate indebtedness (as defined) to net capital may not exceed 15 to 1. ARCAS computes its net capital under the alternative method. This method requires that minimum net capital not be less than the greater of $250,000 or 2% of aggregate debit items arising from customer transactions.

As of December 31, 2005 and 2004, these subsidiaries were in compliance with their respective net capital requirements and their net capital, net capital in excess of required net capital, and ratio of aggregate indebtedness to net capital were as follows (in thousands, except ratios):

		December 31,
		2005		2004
Net capital
	Wave	$	5,027	$	19,427
	ARCAS		13,063		7,043
	ATSI		5,671		2,652
	ABS		405		N/A
Net capital in excess of required net capital
	Wave	$	4,497	$	18,519
	ARCAS		12,813		6,793
	ATSI		5,589		2,485
	ABS		400		N/A
Ratio of aggregate indebtedness to net capital
	Wave		1.58 to 1		0.70 to 1
	ARCAS		N/A		N/A
	ATSI		0.22 to 1		0.94 to 1
	ABS		N/A		N/A

Advances to affiliates, dividend payments and other equity withdrawals are subject to certain notification and other provisions of the net capital rule of the SEC and other regulatory bodies.

Archipelago's international broker-dealer subsidiaries are subject to capital adequacy requirements promulgated by authorities of the countries in which they operate. As of December 31, 2005 and 2004, these subsidiaries had met their local capital adequacy requirements.

Euronext is a company domiciled in the Netherlands. The consolidated interim financial statements of Euronext for the period ended June 30, 2006 comprise Euronext and its subsidiaries, together referred to as the "Group," and the Group's interests in associates and jointly controlled entities.

2 Basis of preparation and accounting policies

Basis of preparation

The consolidated interim financial statements for the period ended June 30, 2006 have been prepared in accordance with IAS 34 "Interim Financial Reporting." The consolidated interim financial statements do not include all the information and disclosures required in the annual financial statements, and should be read in conjunction with the Group's annual financial statements as at December 31, 2005.

Significant accounting policies

The accounting policies and methods of computation used for the preparation of the financial information as of June 30, 2006 and for the periods ended June 30, 2006 and 2005 are consistent with those used in the consolidated financial statements for the year ended December 31, 2005, with the following exception, which was first applied as at January 1, 2006:

In 2005, the IASB made an amendment to IAS 39 "Financial Instruments: Recognition and Measurements"—the Fair Value Option—effective for financial statements beginning on or after January 1, 2006. This amendment limits the possibility to designate a financial asset or a financial liability (or a group of financial assets, financial liabilities or both) on initial recognition as at fair value through profit or loss. As a consequence, certain investments held by the Group that were previously classified as investments at fair value through profit and loss have been reclassified as available-for-sale. These investments continue to be stated at fair value, while any resultant unrealized gains or losses are recognized directly in equity, as from January 1, 2006

As a result of this change in accounting policy, a total expense of € 0.8 million (€ 0.6 million after tax) that would have been recognized in the income statement, has been recognized directly in equity in the six-month period ended June 30, 2006.

The other amendments to standards (IAS 19, IAS 21, IAS 39, IFRS 4) and interpretations (IFRIC 4, IFRIC 5, IFRIC 6) mandatory for the financial year ending December 31, 2006 and effective for financial statements beginning on or after January 1, 2006 have no impact on the Group.

Amendments to standards (IAS 1, IFRS 7) and interpretations (IFRIC 7, IFRIC 8, IFRIC 9) that were issued but are not effective for 2006 have not been early adopted by the Group.

Reconciliation to U.S. GAAP

The application of U.S. GAAP would have affected the Group's consolidated net income for the six-month period ended June 30, 2006 and its shareholders' equity as of June 30, 2006. For an explanation

of the variation, reference is made to paragraph 11 "Summary of Differences Between International Financial Reporting Standards and United States Generally Accepted Accounting Principles."

3 Volatility of revenues

The revenues of the Group are influenced more by the volatility and volume of transactions in the capital market than by seasonal factors.

4 Cash management

Investments and disinvestments in current short-term financial assets are made in the context of the overall management of the Group's cash position of which cash, cash equivalents and short-term financial investments constitute a global treasury portfolio. In the six-month period ended June 30, 2006, the short-term financial assets decreased by € 102.9 million, consisting of € 98.8 million net disposal of short-term financial assets (cash component) and € 4.2 million revaluation (non-cash component).

ACQUISITIONS

Increase in investment in GL TRADE

GL Trade founders were granted a put option on up to 10.5% of GL TRADE share capital. The option can be exercised at any time after February 28, 2006. The exercise price has been set at the average market value of the previous 40 trading days, less 1 euro. The present value of the exercise price of the option is reflected as a non-current financial liability. The difference between the exercise price of the put option and the corresponding minority interest has been recognized as goodwill.

Other acquisitions

In the first quarter of 2006, the Group acquired Companynews Group, a distributor of news from listed companies. The purchase price of Companynews Group amounted to € 5.6 million. The assets, liabilities, results and cash flows of CompanynewsGroup have been included in the consolidated financial statements of Euronext from March 1, 2006 onwards.

In 2005, Euronext and Borsa Italiana through MBE Holding subscribed to 51% of the share capital of MTS. As a result of a pre-emptive rights and sale mechanism, MBE Holding was committed to acquire an additional stake in MTS of 9.37%. The Euronext share in the commitment, €12.6 million, was reflected as a financial liability at December 31, 2005. In 2006 this additional share capital was paid for in cash

DISPOSALS

CIK

On November 9, 2005 Euroclear plc and Euronext signed a share purchase agreement for the full acquisition by Euroclear plc of CIK, the central securities depository of Belgium that was a wholly-owned subsidiary of Euronext. This transaction has been completed on January 1, 2006 and Euronext ceased to control and therefore to consolidate CIK from January 1, 2006. The capital gain recognized in January 2006 amounts to € 15.5 million.

Prior to their disposal, the assets and liabilities of CIK were considered as "held for sale" according to the definitions of IFRS 5 "Non-current Assets Held-for-sale and Discontinued Operations" with subsequent recognition as "Disposal groups assets classified as held-for-sale" and "Liabilities directly associated with disposal groups assets classified as held-for-sale" in the balance sheet.

9 Legal Proceedings

Certain claims have been submitted against the Group and are being contested by the Group companies concerned. In view of the information currently available, legal advice obtained and the amounts provided for, it is expected that the outcome will not have a substantial adverse effect on the Group's financial position. The most important litigation relates to the following:

Via Net.Works Inc.

Following the IPO of Via Net.Works Inc. on the Euronext Amsterdam market and Nasdaq on February 11, 2000, the Euronext Amsterdam market was criticized by the media for allowing trading in shares of Via Net.Works Inc. to start before trading started on Nasdaq. Prior to the start of trading of these shares on Nasdaq, trading on the Euronext Amsterdam market opened and closed at a price of € 89 per share. After the close of trading on the Amsterdam market, trading on the Nasdaq opened at a price of $41 per share. At the start of the next trading day, Via Net.Works Inc. share price on the Amsterdam market dropped to € 50 per share. The STE (the predecessor of the AFM) conducted an inquiry into the listing of Via Net.Works. In 2002, the AFM notified Euronext Amsterdam that it had decided not to fine or sanction the company in connection with this IPO. This decision is final.

Following the IPO, legal proceedings were instituted against the Amsterdam Exchanges N.V., the predecessor of Euronext Amsterdam, by a private investor and the Via Net.Works Foundation, claiming to represent approximately 600 investors and currently claiming compensation in respect of trading losses of approximately € 11 million. Euronext Amsterdam is strongly defending itself against these claims. The private investor claim (€ 250,000) and Foundation claim were both dismissed by the District Court of Amsterdam. Appeals were filed by the parties with the Amsterdam Court of Appeals and judgment is pending in both cases.

NCP

Damages claimed to date total 73.8 million euros. Since the basis of the claim and its legal grounds were considered unclear, no provision was recorded as of December 31, 2005 or as of June 30, 2006.

Trading Technologies

Euronext's subsidiary, GL TRADE, is involved in a litigation initiated by Trading Technologies (TT) in the U.S., which also concerns other companies in the same industry as GL TRADE. TT alleges infringement of its patents relating to trading screen technology. TT has not yet specified the amount of damages it is seeking. Since it pre-existed TT by many years, GL TRADE believes that it has a strong "prior art" defense, and therefore did not record a provision in respect of this litigation as of December 31, 2005 or as of June 30, 2006.

In the six-month period ended June 30, 2006, Atos Euronext Market Solutions invoiced € 78.2 million of IT expenses (June 30, 2005: € 36.6 million) of which € 68.6 million is charged to the income statement (June 30, 2005: € 35.2 million) and € 9.6 million is capitalized (June 30, 2005: € 1.4 million). The Group charged € 10.2 million to Atos Euronext Market Solutions in connection with services rendered and other recharges (June 30, 2005: € 3.2 million).

Transactions with LCH.Clearnet

The income from LCH.Clearnet largely consists of retrocession fees collected by LCH.Clearnet from Clearing members, for clearing services provided in relation to their transactions on the markets operated by Euronext. LCH.Clearnet pays to the Group part of these fees collected on its behalf. These retrocession fees are recognized as revenues in the line items "Cash Trading" and "Derivatives Trading" in the income

11 Summary of differences between International Financial Reporting Standards and United States Generally Accepted Accounting Principles

The consolidated financial statements of Euronext Group have been prepared in accordance with International Financial Reporting Standards ("IFRS").

IFRS differ in certain significant respects from accounting principles generally accepted in the United States of America ("U.S. GAAP").

The application of U.S. GAAP would have affected the Group's consolidated net income attributable to shareholders of the parent company for the six-month periods ended June 30, 2006 and 2005 and its shareholders' equity as of June 30, 2006 and December 31, 2005 as provided in the tables below.

11.3 Description of differences between accounting principles applied to prepare the consolidated financial statements under IFRS and U.S. GAAP

A—Business Combinations

For financial reporting purposes, the cost of acquiring a business is allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition for both IFRS and U.S. GAAP. Any excess of purchase cost over the fair values assigned to the acquired net assets is reported as goodwill.

Under IFRS, goodwill and acquired identifiable intangible assets were amortized ratably to earnings over their estimated useful lives. The Group adopted IFRS 3 for all business combinations agreed on or after March 31, 2004 and consequently did not amortize goodwill on acquisitions made after March 31, 2004. Starting January 1, 2005, the Group no longer amortizes goodwill relating to acquisitions made before March 31, 2004. When necessary, goodwill impairment charges are reported in earnings with a corresponding reduction in the carrying value of goodwill.

Under U.S. GAAP, goodwill acquired in business combinations occurring prior to June 30, 2001 was capitalized and amortized on a straight-line basis over its estimated useful life with respect to business combinations completed prior to June 30, 2001. In its application of U.S. GAAP, the Group first applied the provisions in Statement of Financial Accounting Standards (SFAS) No. 141 "Business Combinations" ("SFAS 141") and SFAS No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142") for business combinations initiated after June 30, 2001. From January 1, 2002, the provisions of SFAS 142 were also applied to goodwill and other intangible assets acquired prior to June 30, 2001. Since the adoption of SFAS 141 and SFAS 142, goodwill and indefinite life intangible assets are no longer amortized, but instead tested, at least annually, for impairment.

Application of U.S. GAAP under SFAS 141 and 142 required the Group to identify, to measure, and to separately account for intangible assets such as licenses, customer relationships, trademarks and technology apart from goodwill. For this purpose, independent valuations were prepared using estimates and assumptions provided by management.

The significant transactions were revisited for U.S. GAAP purposes and include the merger between the Amsterdam, Brussels and Paris exchanges in 2000, the acquisitions of Liffe and BVLP in 2002, the acquisition of MTS in 2005 and the acquisition of a further 10 % stake in GL TRADE in 2005 as well as the Atos Euronext, AEMS and LCH.Clearnet transactions.

In addition, reconciling items related to impairment arise based on differences in the initial measurement of other intangible assets described above and the impairment test itself. The impairment test under IFRS consists of comparing the carrying amount of an asset to its recoverable amount, which is the higher of the fair value less costs to sell and the value in use of the asset. The excess of the carrying amount over the recoverable amount is recorded as an impairment loss.

Under U.S. GAAP, the impairment test for intangible assets subject to amortization is conducted in two steps. The first step is to compare the carrying amount to undiscounted future cash flows. If the carrying amount is higher than the sum of the undiscounted cash flows, the second step is to calculate the impairment based on discounted cash flows expected from the use and eventual disposition of the asset. For intangible assets not subject to amortization, the impairment test consists of a comparison of the fair

EURONEXT N.V.

NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

11.3 Description of differences between accounting principles applied to prepare the consolidated financial statements under IFRS and U.S. GAAP (Continued)

value of the intangible assets to its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Under U.S. GAAP goodwill is tested for impairment annually. The impairment test is also comprised of two steps. The initial step is designed to identify potential goodwill impairment by comparing an estimate of the reporting unit's fair value of all assets and liabilities, including goodwill, to their carrying amounts. If the carrying amount exceeds the fair value of the reporting unit, a second step is performed, which compares the implied fair value of the applicable reporting unit's goodwill with the carrying amount of that goodwill, to measure the amount of goodwill impairment, if any.

Since the identifiable intangible assets other than goodwill do not have a tax basis, a deferred tax liability was recognized by the Group under U.S. GAAP for the tax consequences on the related temporary differences. These temporary differences reverse and the deferred tax liability is being reduced as the carrying amounts of the intangible assets are being amortized to earnings. Such difference is reflected as a separate reconciling line item in the above tables.

The differences in carrying amounts of intangible assets (including goodwill) between IFRS and U.S. GAAP result in different gains and losses on subsequent sales of activities and deferred tax liability reversals.

The schedule below reflects the impact of the adjustments from IFRS to U.S. GAAP as at December 31, 2005 and June 30, 2006 for the above mentioned business combinations and the effect of the adjustments mentioned below in Notes J and K.

		June 2006	December 2005	Estimated Useful Life
		In thousands of euros
Decrease in goodwill		428,804	399,450
Increase in:

Total intangibles (including goodwill)		227,933	266,692
Increase in deferred tax liabilities on intangibles		194,801	203,660

B—Admission fees

The Group collects admission fees from issuers that first offer their securities for trading in the public market. The group immediately recognizes such fees as revenue under the guidance in IAS 18, "Revenue" when an issuer's securities are first listed.

U.S. GAAP interpretation provided by the Securities and Exchange Commission ("SEC") reflected in the SEC Staff Accounting Bulletin No. 104, "Revenue Recognition," requires recognition of those admission fees over the period in which the services are provided. Accordingly, under U.S. GAAP, the Group recognizes admission fees on a straight-line basis over the estimated service periods of 10 years.

C—Derivatives and hedging

Under IFRS, the Group incurred a £250 million denominated fixed-rate debt obligation in February 2004 that was economically swapped into a floating rate liability using an interest rate swap that was designated by management as a fair value hedge of interest rate risk in accordance with IAS 39, "Financial Instruments." Under the fair value hedge both qualifying portion of the debt and the interest rate swap contract are carried at fair value with changes in fair value being reported in earnings.

The documentation established for IAS 39 purposes does not comply with U.S. GAAP requirements because the prospective effectiveness assessment under IAS 39 is documented by analyzing the critical terms of the swap and the bond, which is not permitted under U.S. GAAP. As a result, for U.S. GAAP purposes, this interest rate swap does not qualify as a hedging instrument. Therefore the bond remains reported at amortized cost, and the swap is recognized as a trading derivative which is marked to market at each reporting period through earnings.

D—Financial instruments

Under IFRS, Euronext's current investments in equity and Money Market Funds have been designated by management as "Financial assets at Fair Value through Profit and Loss" ("the Fair Value Option") in accordance with IAS39.9. As a consequence of the amendment to IAS 39 the Fair Value Option effective for annual periods beginning on or after January 1, 2006, current investments in equity shares held by the Group previously classified as investments at fair value through Profit and Loss in 2005 have been reclassified as available for sale in 2006 (with changes in fair value through equity)."

Under U.S. GAAP, SFAS 115 "Accounting for Certain Investments in Debt and Equity Securities," does not allow an entity to apply the IFRS "Fair value option" and these investments are reported as available for sale (AFS) securities at fair value under SFAS 115, "Accounting for Investments in Debt and Equity Securities," with unrealized gains and losses being reported in stockholders' equity net of their related tax consequences.

E—Foreign currency exchange gains and losses on available for sale debt securities

Under IFRS and U.S. GAAP, investments in debt securities that are classified by management as AFS are carried in the balance sheet at fair value with changes in fair value reported directly in stockholders' equity.

For purposes of determining the change in fair value to be reported in equity, the portion of the change in value relating to foreign currency exchange rate changes that occur during the period are reported in earnings and are not deferred in stockholders' equity for IFRS.

Under U.S. GAAP, under the guidance in EITF 96-15 "Accounting for the Effects of Changes in Foreign Currency Exchange Rates on Foreign-Currency-Denominated Available-for-Sale Debt Securities," as amended by SFAS 133 "Accounting for Derivative Instruments and Hedging Activities," changes in value of AFS securities that result from changes in foreign currency exchange rates are reported in shareholder's equity and transferred to earnings as a component of gain or loss only upon sale of the instrument.

F—Employee benefits

Under IFRS, accounting for pensions and other post-employment benefits is made in accordance with IAS19, "Employee Benefits." The Group's net obligation is measured by estimating future benefits employees have earned. Pension and benefit costs are recognized in earnings over the service periods.

The significant differences between IAS 19 and U.S. GAAP under SFAS 87, "Accounting for Pensions," SFAS 88, "Accounting for Pension Settlements and Curtailments," SFAS 106, "Accounting for Postretirement Benefits," and SFAS 112, "Employers' Accounting for Post Employment Benefit," that affect the Group are:

•: Different dates of implementation for the parent company of the Group caused most of the differences in the accumulated actuarial gains and losses. For the acquired entities, both IAS 19 and U.S. GAAP have been implemented since the acquisition date.
•: In addition, under U.S. GAAP, an additional minimum liability should be recognized if the positive difference between the accumulated benefit obligation and the fair value of the plan assets is greater than the accrued liability. The additional minimum liability is recognized and an intangible asset is recognized for an amount not exceeding the amount of unrecognized prior service cost. If the additional minimum liability required to be recognized exceeds unrecognized prior service cost, the excess is reported as a reduction of other comprehensive income as a component of shareholders' equity. Such an additional minimum liability is not recognized under IAS 19.

The effect of these differences on shareholders' equity can be summarized as follows:

	June 30, 2006		December 31, 2005
	(Thousands of euros)
Accumulated actuarial gains and losses	(4,265	)	(4,172	)
Additional Minimum Pension Liability	(682	)	(17,271	)

U.S. GAAP adjustment	(4,947	)	(21,443	)

G—Share-based payments

In accordance with IFRS2 "Share-based Payment", Euronext recognized compensation expenses for all share-based programs that were granted after November 7, 2002. An estimated cost for the granted instruments, based on the instruments' fair value at grant date and the number of instruments expected to vest is charged to the income statement, with a corresponding increase in equity or liabilities if the award is cash-settled, over the vesting period on a straight line basis. The fair value of the options is measured using a binomial model, taking into account the terms and conditions upon which the options were granted. As of June 30, 2006, there are no grants outstanding which would require cash settlement.

Under U.S. GAAP, until December 31, 2005, Euronext applied the intrinsic value method in accordance with Accounting Principles Board Opinion 25, "Accounting for Stock Issued to Employees" ("APB 25") for share-based programs with employees, including those plans prior to November 7, 2002, and the plans are either classified as fixed or variable plans. Under APB 25, compensation expense is determined, using the intrinsic value method, as the difference between the market price and the exercise

NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

11.3 Description of differences between accounting principles applied to prepare the consolidated financial statements under IFRS and U.S. GAAP (Continued)

price of the share-based award. For fixed plans compensation expense is determined on the grant date. For variable plans compensation is remeasured at each balance sheet date until the award becomes vested.

Starting January 1, 2006, the Company adopted SFAS 123 (R) "Share-Based Payments," using the prospective modified method. Under the modified prospective method, share-based compensation is recognized based on the fair value of the awards for:

•: New share-based payment awards granted;
•: Awards modified, repurchased, or cancelled after the required effective date; and
•: The remaining portion of the requisite service under previously-granted
•: Unvested awards outstanding as of the required effective date.

The main effect of adopting the standard on January 1, 2006 concerned Euronext stock option awards granted in 2004. Under FAS 123R, Euronext stock option awards granted in 2004, which was previously classified as an equity instrument under APB 25, is classified as a liability. This liability was recognized at its fair value of €6 million at January 1, 2006 by reducing equity. The difference between the fair value of the liability recognized at January 1, 2006 and the previously recognized compensation cost until that date amounted to €0.2 million and was recognized in the income statement, net of any related tax effect, as the cumulative effect of the change in accounting principle. The fair value of this liability-classified award is remeasured at each period-end based on the current share price and other pertinent factors. The change in the fair value of this liability-classified award, net of any related tax effect was recognized in the income statement of the period as an additional stock compensation expense.

H—Software Revenue Recognition

LIFFE CONNECT® software sales comprise revenues from fees received for the sale of software licenses. These revenues are recognized in accordance with the substance of the licensing agreements. Under IFRS, revenues from licensing agreements with a specified period of time are amortized on a straight-line basis over the life of the agreements. Fees received under unlimited licensing agreements for which the Group has no remaining obligations to perform or to deliver are recognized immediately.

Under U.S. GAAP, the rules for revenue recognition under multiple-element arrangements are detailed and prescriptive. These rules include the requirement that revenues be allocated to the respective elements of such an arrangement on the basis of Vendor Specific Objective Evidence ("VSOE") for each element. Statement of Position ("SOP") 97-2 'Software Revenue Recognition' sets out precise requirements for establishing VSOE for valuing elements of certain multiple-element arrangements. When VSOE for individual elements of an arrangement cannot be established in accordance with SOP 97-2, revenue is generally deferred and recognized over the term of the final element.

Under U.S. GAAP, the Group did not have VSOE for certain elements of certain multiple-element arrangements with customers within the LIFFE business. The terms of these arrangements with customers include, among other terms, the provision of hosting services and on-going customer support (known as PCS under SOP 97-2). As a consequence of the terms of these arrangements, revenue is deferred under U.S. GAAP and does not start to be recognized until delivery or discharge of the obligation in respect of

the final element of the arrangement for which VSOE is not determinable. If this final element is PCS, then revenue is recognized over the remaining term of the PCS contract.

I—Other

This reconciling item mainly reflects U.S. GAAP adjustments at G/L Trade and AEMS mainly related to goodwill amortization, revenue recognition differences and restructuring liabilities.

J—Put options granted to minority interests

Under IFRS, the Group has committed itself to acquiring minority shareholdings owned by third parties in certain less than 100%-owned consolidated subsidiaries. Since these third parties have the ability, if they wish so, to decide to exercise their put options, IAS 32 requires that the present value of the exercise price of such options be accounted for as a financial liability, no minority interest recognized for accounting purposes and the difference (if any) booked as part of goodwill. The goodwill is adjusted at each closing date to reflect the variation of the liability (due to changes in the exercise price of the option).

Under U.S. GAAP, these put options are recorded as liabilities measured initially at fair value and consequently with changes in fair value recognized into earnings.

K—MBE Holding

Under IFRS, MBE Holding is being consolidated under the proportional consolidation method.

Under U.S. GAAP, it was determined that MBE Holding should be accounted for under the equity method primarily because the minority shareholder holds significant participating rights.

Amounts reflected in the Group's consolidated balance sheet under IFRS with respect to MBE Holding include current assets of €20.1 million, non-current assets of €81.4 million, current liabilities of €7.6 million and non-current liabilities of €0.9 million as of June 30, 2006.

L—Tax Effect of other U.S. GAAP adjustments

The tax effect of other U.S. GAAP adjustments represents the temporary differences created as a result of applying U.S. GAAP.

Cash Flow statement

For IFRS, Euronext prepares and reports financial information on its cash flows using the guidance in IAS 7, Cash Flow Statements. Since the information required under IAS 7 is similar to the content and presentation of cash flow information prepared under U.S. GAAP under FASB Statement 95, Statement of Cash Flows, Item 17 of SEC Form 20-F does not require additional information, disclosure or a different presentation of cash flow information for the Group.

11.4 Recently issued accounting pronouncements

On June 7, 2005, the FASB issued Statement N^o154, Accounting Changes and Error Corrections, a replacement of APB Opinion N^o20, Accounting Changes, and Statement N^o3, Reporting Accounting

FIN-107

EURONEXT N.V.

NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

11.4 Recently issued accounting pronouncements (Continued)

Changes in Interim Financial Statements. Statement 154 changes the requirements for the accounting for and reporting of a change in accounting principle. Previously, most voluntary changes in accounting principles required recognition via a cumulative effect adjustment within net income of the period of the change. Statement 154 requires retrospective application to prior periods' financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. Statement 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the Statement does not change the transition provisions of any existing accounting pronouncements. Management does not believe adoption of Statement 154 will have a material effect on its consolidated financial position, results of operations and cash flows.

In July 2006, the FASB issued FASB Interpretation No. (FIN) 48, Accounting for Uncertainty in Income Taxes, an interpretation of Statement of Financial Standards (SFAS) No. 109, Accounting for Income Taxes. FIN 48 addresses how a reporting company accounts for all tax positions including the uncertain tax positions reflected or expects to be reflected in the company's past or future tax returns. The interpretation also requires the company to recognize interest and penalties associated with the uncertain tax positions. This interpretation is effective for fiscal years beginning after December 15, 2006. The Company is currently evaluating the potential impact, if any, that the implementation of FIN 48 will have on its financial condition, results of operations and cash flows;

In July 2006, the FASB affirmed its previous decision to make the recognition provision of its proposed standard, Employer's Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132R, effective for public companies for fiscal years ending after December 15, 2006. This decision requires the recognition on the statement of financial condition of the funded status of pension and other postretirement benefit plans. The company is currently evaluating the potential impact, if any, that the implementation of the proposed standard, if and when issued in final form, may have on its stockholders' equity.

In 2005, IASB made an amendment to IAS 39 "Financial Instruments: Recognition and Measurements"—the Fair Value Option—effective for financial statements beginning on or after January 1, 2006. This amendment limits the possibility to designate a financial asset or a financial liability (or a group of financial assets, financial liabilities or both) on initial recognition as at fair value through profit or loss. As a consequence, certain investments held by the Group that were previously classified as investments at fair value through profit and loss have been reclassified as available-for-sale. These investments continue to be stated at fair value, while any resultant unrealized gains or losses are recognized directly in equity, as from 1 January.

The other amendments to standards (IAS 19, IAS 21, IAS 39 and IFRS 4) and interpretations (IFRIC 4, IFRIC 5 and IFRIC 6) mandatory for the financial year ending December 31, 2006 and effective for financial statements beginning on or after January 1, 2006 are either not applicable or have no material impact on the Group.

Amendments to standards (IAS 1 and IFRS 7) and interpretations (IFRIC 7, IFRIC 8 and IFRIC 9) that were issued but are not effective for 2006 have not been early adopted by the Group.

Independent Accountants' Report

To the Managing Board of Euronext N.V.:

We have audited the accompanying consolidated balance sheets of Euronext N.V., Amsterdam, The Netherlands, and its subsidiaries as of December 31, 2005, 2004 and 2003, and the related consolidated statements of income, changes in equity, and cash flows for the years then ended. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Euronext N.V. and its subsidiaries as of December 31, 2005, 2004 and 2003, and the results of their operations and their cash flows for the years then ended in conformity with International Financial Reporting Standards as adopted by the European Union.

As discussed in note 2 to the consolidated financial statements, Euronext N.V. early adopted IFRS 2 "Share-based Payment" as of January 1, 2004. Euronext N.V. adopted IFRS 3 "Business combinations" and the related changes to IAS 36 "Impairment of assets" and IAS 38 "Intangible assets" for all business combinations agreed on or after March 31, 2004. Starting January 1, 2005, Euronext no longer amortizes goodwill relating to acquisitions made before March 31, 2004. Finally, Euronext adopted IFRS 5 "Non- current assets held for sale and Discontinued Operations" as from January 1, 2005.

International Financial Reporting Standards as adopted by the European Union vary in certain significant respects from U.S. generally accepted accounting principles. Information relating to the nature and effect of such differences is presented in Note 3.14 to the consolidated financial statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

2. INTRODUCTION TO THE NOTES AND ACCOUNTING POLICIES

Introduction

Euronext N.V. (hereafter: Euronext) is a company domiciled in the Netherlands. Euronext's services range from facilitating public offerings and providing trading facilities for cash and derivative products to supplying market data. It benefits from clearing services provided by LCH.Clearnet Group Ltd., and Settlement and Custody services provided by local CSDs and through its partnership with Euroclear plc. In addition to its trading-related businesses, Euronext also sells software and IT solutions through Atos Euronext Market Solutions Holding S.A.S. and its subsidiary GL TRADE S.A.

The consolidated financial statements of Euronext for the year ended December 31, 2005, 2004 and 2003 comprise Euronext and its subsidiaries together referred to as the "Group" and the Group's interest in associates and jointly controlled entities.

Statement of compliance

The consolidated financial statements for the years 2005, 2004 and 2003 have been prepared in accordance with the International Accounting Standards (IASs) and International Financial Reporting Standards (IFRSs) as adopted by the European Union which became applicable as of that year for the preparation of statutory financial statements. They are also in accordance with the IFRS and their respective interpretations adopted by the International Accounting Standards Board (IASB).

Reconciliation to U.S. GAAP

The consolidated financial statements of Euronext Group have been prepared in accordance with International Financial Reporting Standards ("IFRS") as described above. IFRS differ in certain significant respects from accounting principles generally accepted in the United States of America ("U.S. GAAP"). For an explanation of the variation, reference is made to paragraph 3.14 "Summary of Differences between International Financial Reporting Standards and United States Generally Accepted Accounting Principles."

Changes in the scope of consolidation

The impact of changes in the scope of consolidation is detailed in paragraphs 3.9: "Effect of acquisitions, contributions and disposals" and 3.5 "Discontinued Operations."

Changes in the scope of consolidation—2005

In 2005, the following entities have been included for the first time in the scope of consolidation:

•: MBE Holding S.p.A.,
•: Societa per il Mercato del Titoli di Stato S.p.A. (hereafter: MTS),
•: CScreen Ltd.,
•: OASIS Inc.,
•: Euronext Real Estate S.A./N.V.

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

MBE Holding S.p.A.

MBE Holding S.p.A. is 51% owned by Euronext and 49% by Borsa Italiana S.p.A. and was created in November 2005 as the holding company controlling MTS. As the Group and Borsa Italiana S.p.A. jointly control MBE Holding S.p.A., Euronext consolidates proportionally 51% of MBE Holding S.p.A.'s assets, liabilities, revenue and expenses.

MTS

MTS is a leading electronic trading platform for European wholesale fixed-income securities, in particular for government and sovereign bonds. Euronext and Borsa Italiana S.p.A., through MBE Holding S.p.A., subscribed to a controlling 51% interest in MTS's share capital on November 18, 2005. The remaining MTS shares were subject to a pre-emptive rights subscription and sale mechanism first between the historical shareholders and MTS dealers, where the latter became new shareholders, and subsequently to MBE Holding S.p.A. As a result of the pre-emptive rights and sale mechanism, MBE Holding S.p.A. was committed to acquire as at December 31, 2005 an additional stake in MTS leading to a 60.37% ownership of MTS by MBE Holding S.p.A.

As MBE Holding S.p.A. is jointly controlled by Euronext (51%) and Borsa Italiana S.p.A. (49%), Euronext consolidates proportionally 51% of MTS consolidated assets, liabilities, revenues and expenses. The Group's proportionate ownership percentage is 30.79% and a minority interest of 20.21% is therefore accounted for.

CScreen Ltd.

On April 19, 2005, the Group acquired through its subsidiary LIFFE all of the issued share capital of CScreen Ltd. CScreen Ltd. is the provider of a leading pre-trade price discovery platform for wholesale equity derivatives. As Euronext controls LIFFE, Euronext fully consolidates the financial statements of this new subsidiary. The Group ownership percentage is 100%.

OASIS Inc.

The Group acquired through its subsidiary GL TRADE S.A. all the shares of the U.S.-based OASIS Inc., on July 7, 2005. OASIS Inc. is a software and service company specializing in high-performance "Straight Through Processing" applications. As Euronext controls GL TRADE S.A., Euronext fully consolidates the financial statements of this new subsidiary.

Euronext Real Estate S.A./N.V.

This entity was created in 2005. At balance sheet date it is dormant.

Contributions to Atos Euronext Market Solutions Holding S.A.S.

In 2005, the Group extended its relationship with Atos Origin through AtosEuronext SBF S.A. with the contribution of additional assets and activities by both parties. An agreement to that purpose was signed on July 22, 2005. Under this agreement a new company, Atos Euronext Market Solutions Holding S.A.S. was created, owned 50% by both parties while under Atos Origin control. For further information, reference is made to paragraph 3.9.2.

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Changes in the scope of consolidation—2004

The assets, liabilities, results and cash flows of 2 entities acquired by GL TRADE S.A, Davidge and Ubitrade, are included in the Group's consolidated financial statements since the date of their acquisition in 2004.

Changes in the scope of consolidation—2003

The Group disposed of the shares it held in BCC/Clearnet on December 22, 2003. As from that date, assets, liabilities, results and cash flows of BCC/Clearnet have been deconsolidated.

On July 24, 2003 the remaining 50% of shares in joint venture NQLX LLC held by NASDAQ were withdrawn, the Group thus becoming the sole shareholder. From that date onwards the assets, liabilities, results and cash flows of NQLX LLC are fully consolidated in the Group's consolidated financial statements.

The assets, liabilities, results and cash flows of three entities acquired by GL TRADE S.A. are included in the Group's consolidated financial statements since November 4, 2003, the date of their acquisition. Assets, liabilities, results and cash flows of 4-D Trading (also acquired by GL TRADE S.A.) were acquired in April 2003 and have been included in the consolidated financial statements since that date.

Changes in accounting policies

The IASB introduced a number of modifications to existing IFRSs and IASs which became applicable as from January 1, 2005. The Group adopted all these changes as from their effective dates, although their effect on the Groups financial statements is immaterial for 2005. One of the standards becoming applicable as from January 1, 2005 is IFRS 5 "Non-current assets held-for-sale and Discontinued operations." Earlier transactions and disposals such as the sale of Clearing activities in 2003 were reported on the basis of IAS 35 "Discontinuing Operations."

In addition, the Group adopted early IFRS 2 "Share-based Payments" in 2004. It also adopted IFRS 3 and related changes to IAS 36 "Impairment of assets" and IAS 38 "Intangible assets" for all business combinations agreed on or after March 31, 2004. Starting January 1, 2005 the Group no longer amortizes goodwill relating to acquisitions made before March 31, 2004 as part of a business combination, in line with IFRS 3. The impact of the application of this standard is that goodwill amortization impacted results of operations and net result attributable to shareholders of the Company by EUR 39.9 million in 2004 and EUR 64.8 million in 2003 directly and an additional amount indirectly due to the investments in associates of EUR 12.2 million in 2004.

Significant accounting policies

(A) Basis of preparation

The financial statements are presented in euros, rounded to the nearest thousand. They are prepared on the historical cost basis except for financial assets and liabilities which are stated at fair value through profit or loss and available-for-sale financial assets which are both stated at fair value.

Non-current assets and disposal groups held-for-sale are stated at the lower of their carrying amount and fair value less costs to sell.

The preparation of financial statements in conformity with IFRSs requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of

FIN-116

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

assets and liabilities, income and expenses. The most significant judgments are those in relation to impairment of assets, provisions, employee benefits and litigation. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making the judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements by the parent organization and the Group entities.

(B) Basis of consolidation

(i) Subsidiaries

Subsidiaries are entities controlled by Euronext. Control exists when Euronext has the power, directly or indirectly, to govern the financial and operating policies of an entity so as to obtain benefits from its activities. In assessing control, potential voting rights that presently are exercisable or convertible are taken into account. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. Acquisitions of subsidiaries are accounted for using the purchase method of accounting. The fair value of the assets and liabilities of newly acquired subsidiaries is the cost price of these assets and liabilities for the Group.

(ii) Associates

Associates are those entities in which the Group has significant influence, but not control, over the financial and operating policies. The consolidated financial statements include the Group's share of the total recognized gains and losses of associates on an equity accounted basis, from the date that significant influence commences until the date that significant influence ceases.

The Group considers the carrying amount of its investment in the equity of associates and its other long-term interests in an associate when recognizing its share of losses in this associate. When the Group's share of losses exceeds its interest in an associate, the Group's carrying amount is reduced to nil and recognition of further losses is discontinued except to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of an associate.

The financial statements of associates are prepared using accounting principles similar to the Group's accounting principles for like transactions and events in similar circumstances. Reporting dates of associates are similar to the Group's reporting dates.

(iii) Joint ventures

Joint ventures are those entities over whose activities the Group has joint control, established by contractual agreement. The consolidated financial statements include the Group's proportionate share of the entities' assets, liabilities, revenue and expenses with items of a similar nature on a line by line basis, from the date that joint control commences until the date that joint control ceases.

FIN-117

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(iv) Transactions eliminated on consolidation

Intragroup balances and any unrealized gains and losses or income and expenses arising from intragroup transactions, are eliminated in preparing the consolidated financial statements. Unrealized gains arising from transactions with associates and jointly controlled entities are eliminated to the extent of the Group's interest in the entity. Unrealized losses are eliminated in the same way as unrealized gains, to the extent that there is no evidence of impairment.

(C) Foreign currency translation

(i) Foreign currency transactions

Transactions in foreign currencies are translated at the foreign exchange rate ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are translated to euro at the foreign exchange rate ruling at that date. Foreign exchange differences arising on translation are recognized in the income statement. Non-monetary assets and liabilities that are measured in terms of historical cost in a foreign currency are translated using the exchange rate at the date of the transaction. Non-monetary assets and liabilities denominated in foreign currencies that are stated at fair value are translated to euro at foreign exchange rates ruling at the balance sheet dates the fair value was determined.

(ii) Financial statements of foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising on consolidation, are translated to euro at foreign exchange rates ruling at the balance sheet date. The revenues and expenses of foreign operations are translated to euro at rates approximating to the foreign exchange rates ruling at the dates of the transactions. Foreign exchange differences arising on retranslation are recognized directly as a separate component of equity.

(iii) Net investment in foreign operations

Exchange differences arising from the translation of the net investment in foreign operations, and of related hedges are taken to the reserve for currency translation differences. They are released into the income statement upon disposal of the foreign operation.

(D) Derivative financial instruments

The Group may use derivative financial instruments to hedge its exposure to interest rate and foreign currency risks arising from operational and financing activities. In accordance with its treasury policy, the Group does not hold or issue derivative financial instruments for speculative purposes. Derivatives that do not qualify for hedge accounting are accounted for as held-for-trading instruments.

Derivative financial instruments are recognized initially at cost. Subsequent to initial recognition, derivative financial instruments are stated at fair value. The gain or loss on remeasurement to fair value is recognized immediately in profit or loss. However, where derivatives qualify for hedge accounting, recognition of any resultant gain or loss depends on the nature of the item being hedged (see accounting policy E).

FIN-118

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(E) Hedging

(i) Cash flow hedges

Where a derivative financial instrument is designated as a hedge of the variability in cash flows of a recognized asset or liability or a highly probable forecasted transaction, the effective portion of any gain or loss on the measurement to fair value of the derivative financial instrument is recognized directly in equity, with the ineffective portion recognized immediately in the income statement.

(ii) Fair value hedges

The gain or loss that is attributable to the hedged risk on the changes in fair value of a recognized asset or liability or an unrecognized firm commitment designated as a hedged item is recognized in the income statement.

(iii) Hedge of net investment in foreign operation

The portion of the gain or loss on an instrument used to hedge a net investment in a foreign operation that is determined to be an effective hedge is recognized directly in equity. The ineffective portion is recognized immediately in the income statement.

(F) Property, plant and equipment

(i) Owned assets

Items of property, plant and equipment are stated at cost or at deemed cost less accumulated depreciation (see below) and impairment losses (see accounting policy K). The cost of assets includes the initial estimate, where relevant, of the costs of dismantling and removing the items and restoring the site on which they are located.

Where parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items of property, plant and equipment.

(ii) Leased assets

Leases in accordance with the terms of which the Group assumes substantially all the risks and rewards of ownership are classified as financial leases. The owner-occupied property acquired by way of finance lease is stated at an amount equal to the lower of its fair value and the present value of the minimum lease payments at inception of the lease, less accumulated depreciation (see below) and impairment losses (see accounting policy K).

(iii) Subsequent costs

The Group recognizes in the carrying amount of an item of property, plant and equipment the cost of replacing part of such an item when that cost is incurred and if it is probable that the future economic benefits embodied with the item will flow to the Group and the cost of the item can be measured reliably. All other costs are recognized in the income statement as an expense as incurred.

FIN-119

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(iv) Depreciation

Depreciation is charged to the income statement on a straight-line basis over the estimated useful lives of each part of an item of property, plant and equipment. Land is not depreciated. The estimated useful lives are as follows:

Buildings	:	5 - 40 years
IT-equipment	:	2 - 3 years
Other equipment	:	5 - 12 years
Vehicles	:	3 - 4 years
Fixtures and fittings	:	4 - 10 years

The residual value, if not insignificant, is reassessed annually.

(G) Intangible assets

(i) Goodwill

All business combinations are accounted for by applying the purchase method. Goodwill represents the difference between the cost of acquisition and the fair value of the identifiable net assets acquired with the acquisition of subsidiaries, associates and joint ventures.

Goodwill is stated at cost less any accumulated impairment losses and accumulated amortization over the periods prior to January 1, 2005. For acquisitions up to March 31, 2004, goodwill continued to be amortized up to December 31, 2004 while for new acquisitions after March 31, 2004 goodwill is not amortized. Goodwill is allocated to cash-generating units and is tested annually for impairment (see accounting policy K). In respect of investments in associates, the carrying amount of goodwill is included in the carrying amount of the investment in the associate.

Negative goodwill arising on an acquisition is recognized directly in the income statement.

(ii) Research and development

Expenditure on research activities, undertaken with the prospect of gaining technical knowledge and understanding, is recognized in the income statement as an expense as incurred.

Expenditure on development activities, whereby research findings are applied to a plan or design for the production of new or substantially improved products and processes, is capitalized if the product or process is technically and commercially feasible, the cost can be measured reliably, and the Group has sufficient resources to complete development and intends to do so. The expenditure capitalized includes the cost of materials and direct labor. Other development expenditure is recognized in the income statement as an expense as incurred. Capitalized development expenditure is stated at cost less accumulated amortization (see below) and impairment losses (see accounting policy K).

(iii) Other intangible assets

Other intangible assets, which are acquired by the Group, are stated at cost less accumulated amortization (see below) and impairment losses (see accounting policy K).

Expenditure on internally generated goodwill and brands is recognized in the income statement as an expense as incurred.

FIN-120

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(iv) Subsequent expenditure

Subsequent expenditure on capitalized intangible assets is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditure is expensed as incurred.

(v) Amortization

Amortization is charged to the income statement on a straight-line basis over the estimated useful lives of intangible assets unless such lives are indefinite. Goodwill and intangible assets with an indefinite useful life are tested for impairment at each balance sheet date. Other intangible assets are amortized from the date they are available for use. The estimated useful lives are as follows:

Goodwill (up to December 31, 2004)	:	5 - 20 years
Capitalized development costs	:	2 - 3 years
Patents and trademarks	:	5 years

(H) Investments

(i) Investments in debt and equity securities

Investments at fair value through profit or loss are classified as current assets and are stated at fair value, with any resultant gain or loss recognized in the income statement.

Where the Group has the positive intent and ability to hold debt securities to maturity, they are stated at amortized cost less impairment losses (see accounting policy K).

Other financial instruments held by the Group are classified as being available-for-sale and are stated at fair value, with any resultant gains or losses being recognized directly in equity, except for impairment losses and, in the case of monetary items such as debt securities, foreign exchange gains and losses. When these investments are derecognized, the cumulative gains or losses previously recognized directly in equity are recognized in the income statement. Where these investments are interest-bearing, interest calculated using the effective interest method is recognized in the income statement.

The fair value of financial instruments at fair value through profit or loss and financial instruments available-for-sale is their market price at the balance sheet date.

Financial instruments at fair value through profit or loss and available-for-sale investments are recognized/derecognized by the Group on the date it commits to purchase/sell the instruments. Securities held-to-maturity are recognized/ derecognized on the day they are transferred to/by the Group.

(ii) Loans and receivables

Loans and receivables are measured at amortized cost using the effective interest method, with amortization, foreign currency gain or loss resulting from translation of the amortized cost and impairment losses recognized in the income statement.

(I) Trade and other receivables

Trade and other receivables are stated at their amortized cost less impairment losses (see accounting policy K).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(J) Cash and cash equivalents

Cash and cash equivalents comprises cash balances and current investments that are readily convertible into cash. Deposits and other fixed rate interest instruments with an original maturity of less than 3 months and form an integral part of the Group's cash management are included as a component of cash and cash equivalents for the purpose of the statement of cash flows.

(K) Impairment

The carrying amounts of the Group's assets and deferred tax assets (see accounting policy T), are reviewed at each balance sheet date to determine whether there is any indication of impairment. If any such indication exists, the asset's recoverable amount is estimated (see accounting policy K(i)).

For goodwill, intangible assets that have an indefinite useful life and intangible assets that are not yet available for use, the recoverable amount of the asset concerned or of the cash generating unit to which it has been allocated, is estimated at each balance sheet date.

An impairment loss is recognized whenever the carrying amount of an asset or its cash-generating unit exceeds its recoverable amount. Impairment losses are recognized in the income statement.

Impairment losses recognized in respect of cash-generating units are allocated first to reduce the carrying amount of any goodwill allocated to cash-generating units (group of units) and then, to reduce the carrying amount of the other assets in the unit (group of units) on a pro rata basis.

When a decline in the fair value of an available-for-sale financial asset has been recognized directly in equity and there is objective evidence that the asset is impaired, the cumulative loss that has been recognized directly in equity is recognized in the income statement even though the financial asset has not been derecognized. The amount of the cumulative loss that is recognized in the income statement is the difference between the acquisition cost and current fair value, less any impairment loss on that financial asset previously recognized in the income statement.

(i) Calculation of recoverable amount

The recoverable amount of the Group's investments in held-to-maturity securities and receivables carried at amortized cost is calculated as the present value of estimated future cash flows, discounted at the original effective interest rate (i.e., the effective interest rate computed at initial recognition of these financial assets). Receivables with a short duration are not discounted.

The recoverable amount of other assets is the greater of their net selling price and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash-generating unit to which the asset belongs.

(ii) Reversals of impairment

An impairment loss in respect of a held-to-maturity security or receivable carried at amortized cost is reversed if the subsequent increase in recoverable amount can be related objectively to an event occurring after the impairment loss was recognized.

An impairment loss in respect of an investment in an equity instrument classified as available for sale is not reversed through the income statement. If the fair value of a debt instrument classified as available-for-sale increases and the increase can be objectively related to an event occurring after the

FIN-122

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

impairment loss was recognized in the income statement, the impairment loss is reversed, with the amount of the reversal recognized in the income statement.

An impairment loss in respect of goodwill is not reversed.

In relation to other assets, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount.

An impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

(L) Share capital

(i) Repurchase of share capital

When share capital recognized as equity is repurchased, the amount of the consideration paid, including directly attributable costs, is recognized as a change in equity. Repurchased shares are classified as treasury shares and presented as a deduction from total equity.

(ii) Dividends

Dividends are recognized as a liability in the period in which they are declared.

(M) Financial liabilities

(i) Interest-bearing borrowings

Interest-bearing borrowings are recognized initially at fair value less attributable transaction costs. Subsequent to initial recognition, interest-bearing borrowings are stated at amortized cost with any difference between cost and redemption value being recognized in the income statement over the period of the borrowings on an effective interest basis. When borrowings are repurchased or settled before maturity, any difference between the amount repaid and the carrying amount is recognized immediately in the income statement.

(ii) Put options granted to minority shareholders of controlled subsidiaries

The Group has committed itself to acquiring minority shareholdings owned by third parties in certain less than 100%-owned subsidiaries that are included in the consolidation. Since these third parties have the ability, if they so wish, to decide to exercise their put options, IAS 32 requires that the present value of the exercise price of such options be recognized as a financial liability in the Consolidated Financial Statements and no minority interest is recognized for accounting purposes. The difference, if any, between the present value of the exercise price and the minority interest that would otherwise be accounted for, is recognized as part of goodwill. The goodwill will be adjusted at each closing date to reflect the variation of the liability (due to changes in the exercise price of the options) and of the minority interest. Accordingly, there will be no impact on the income statement. If the option expires and is not exercised, the liability will be reversed together with the related goodwill and the minority interest will be reinstated with no impact on the income statement.

(iii) Put options granted to other shareholders of jointly controlled entities

A put option granted to a partner in a jointly controlled entity gives them the ability, if they so wish, to oblige Euronext to acquire their investment in the entity. This is a derivative instrument measured at fair

FIN-123

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

value through profit or loss. The fair value of the option is determined as being the difference between the estimated exercise price and corresponding enterprise value determined on the basis of a discounted cash flow method. When the exercise price exceeds the enterprise value, a liability is recognized through income statement.

(N) Employee benefits

(i) Defined contribution plans

Obligations for contributions to defined contribution pension plans are recognized as an expense in the income statement as incurred.

(ii) Defined benefit plans

The Group's net obligation in respect of defined benefit pension plans is calculated separately for each plan by estimating the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value and the fair value of any plan assets is deducted. The discount rate is the yield at balance sheet date on high quality corporate bonds that have maturity dates approximating to the terms of the Group's obligations. A qualified actuary using the projected unit credit method performs the calculation.

When the benefits of a plan are improved, the portion of the increased benefit relating to past service by employees is recognized as an expense in the income statement on a straight-line basis over the average period until the benefits become vested. To the extent that the benefits vest immediately, the expense is recognized immediately in the income statement.

In calculating the Group's obligation in respect of a particular plan, to the extent that any cumulative unrecognized actuarial gain or loss exceeds 10 per cent of the greater of the present value of the defined benefit obligation and the fair value of plan assets, that portion is recognized in the income statement over the expected average remaining working lives of the employees participating in the plan. Otherwise, the actuarial gain or loss is not recognized.

Where the calculation results in a benefit to the Group, the recognized asset is limited to the net total of any unrecognized actuarial losses and past service costs and the present value of any future refunds from the plan or reductions in future contributions to the plan.

(iii) Long-term service benefits

The Group's net obligation in respect of long-term service benefits, other than pension plans, is the amount of future benefit that employees have earned in return for their service in the current and prior periods. The obligation is calculated using the projected unit credit method discounted to its present value and reduced by the fair value of any related assets. The discount rate is the yield at the balance sheet date on high quality corporate bonds that have maturity dates approximating to the terms of the Group's obligations.

(iv) Share-based payment transactions

Share option programs allow Group employees to acquire shares of Euronext. The fair value of options granted is recognized as an employee expense with a corresponding increase in equity. The fair value is measured at grant date and spread over the period during which the employees become unconditionally entitled to the options. The fair value of the options granted is measured using a binomial lattice model, taking into account the terms and conditions upon which the options were granted. The

FIN-124

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

amount recognized as an expense is adjusted to reflect the actual number of share options that vest except where forfeiture is due only to share prices not achieving the threshold for vesting.

(O) Provisions

A provision is recognized in the balance sheet when the Group has a present legal or constructive obligation as a result of a past event, and it is probable that an outflow of economic benefits will be required to settle the obligation. If the effect is material, provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the time value of money and, where appropriate, the risks specific to the liability.

(i) Restructuring

A provision for restructuring is recognized when the Group has approved a detailed and formal restructuring plan, and the restructuring has either commenced or has been announced publicly. Future operating costs are not provided for.

(P) Trade and other payables

Trade and other payables are stated at their amortized cost.

(Q) Revenue

Revenues are attributed to the period to which they relate.

(i) Services rendered

Revenues from services rendered consist mainly of fees for executing transactions in shares, bonds, options and futures which are recognized at the trade date and billed on a monthly basis. In addition, they include revenue from the sale of exchange information and listing fees, which are initially reported as deferred income and recognized as income over the period in which the services are provided.

(ii) Sales of software

Sales of software comprises revenues from fees received for the sale of software licenses. These revenues are recognized in accordance with the substance of the licensing agreements. Revenues from licensing agreements with a specified period of time are amortized on a straight-line basis over the life of the agreements. Fees received under unlimited licensing agreements for which the Group has no remaining obligations to perform or to deliver are recognized immediately.

(R) Expenses

Expenses are attributed to the period to which they relate.

(i) Operating lease payments

Payments made under operating leases are recognized in the income statement on a straight-line basis over the term of the lease. Lease incentives received are recognized in the income statement as an integral part of the total lease expense.

FIN-125

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(ii) Finance lease payments

Minimum lease payments are apportioned between the finance charge and the reduction of the outstanding liability. The finance charge is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability.

(S) Net financing income

Net financing income comprises interest payable on borrowings calculated using the effective interest rate method, interest receivable on investments, revaluation of financial instruments at fair value through profit or loss, dividend income, foreign exchange gains and losses, and gains and losses on hedging instruments that are recognized in the income statement.

Interest income is recognized in the income statement as it accrues, using the effective interest method. Dividends are recognized in the income statement on the date the right to receive payment is established which in the case of quoted securities is usually the ex-dividend date.

(T) Income tax

Income tax on the income statement for the year comprises current and deferred tax. Income tax is recognized in the income statement except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity.

Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or substantially enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years.

Deferred tax is recorded, using the balance sheet liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The following temporary differences are not provided for: goodwill not deductible for tax purposes, the initial recognition of assets and liabilities that affect neither accounting nor taxable profit, and differences relating to investments in subsidiaries to the extent that they will probably not reverse in the foreseeable future. The amount of deferred tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantially enacted at the balance sheet date.

A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. Deferred tax assets are reduced to the extent that it is no longer probable that the related tax benefit will be realized.

Additional income taxes that arise from the distribution of dividends are recognized at the same time as the liability to pay the related dividend.

(U) Segment reporting

A segment is a distinguishable component of the Group that is engaged either in providing products or services (business segment), or in providing products or services within a particular economic environment (geographical segment), which is subject to risks and rewards that are different from those of other segments.

FIN-126

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(V) Non-current assets held-for-sale and discontinued operations

When the carrying amount of a non-current asset (or disposal group) will be recovered principally through a sale transaction rather than through continuing use, such non current assets (or group of assets and associated liabilities) are classified as held-for-sale. Immediately before classification of disposal groups as held-for-sale, the measurement of the assets (and all assets and liabilities in a disposal group) is brought up-to-date in accordance with applicable IFRSs. Then, on initial classification as held-for-sale, non-current assets and disposal groups are recognized at the lower of carrying amount and fair value less costs to sell. Non-current assets and disposal groups classified as held-for-sale are presented separately from other assets in the balance sheet. The liabilities of a disposal group classified as held-for-sale are presented separately from other liabilities in the balance sheet.

The Group does not depreciate (or amortize) a non-current asset while it is classified as held-for-sale or while it is part of a disposal group classified as held-for-sale.

Impairment losses on initial classification as held-for-sale are included in the income statement. The same applies to gains and losses on subsequent remeasurement.

A discontinued operation is a component of the Group's business that represents a separate major line of business or geographical area of operations or is a subsidiary acquired exclusively with a view to resale.

Classification as a discontinued operation occurs upon disposal or when the operation meets the criteria to be classified as held-for-sale, if earlier.

With the application of IFRS 3 and the subsequent changes in IAS 36 and IAS 38, from January 1, 2005 goodwill is no longer amortized.

Impairment loss on acquisition of Interbolsa S.A.

Ever since its acquisition, the activities of Interbolsa S.A. have been the subject of integration with those of other group entities and in some cases activities have been divested. In the light thereof, management has performed an analysis of the conditions that were considered at the time of acquisition in comparison with budget and activities as at 2003. The value in use is based on discounted cash flows, at a rate of 9.5%. The business model of Interbolsa S.A. has changed. Management concluded that the goodwill paid on the acquisition should be considered impaired for an amount of € 13.8 million.

On June 25, 2003, the Boards of Euronext N.V., BCC/Clearnet and London Clearing House announced their intention to merge Clearnet and London Clearing House Ltd. (LCH) under a new independent UK holding company called LCH.Clearnet Group Ltd. On December 22, 2003, the Group sold its 80.48% stake in the share capital of BCC/Clearnet and 17.7% in that of LCH to LCH.Clearnet Group Ltd. in exchange of 49.1% in the newly formed company. Simultaneously, the Group sold 7.6% of these shares in 2003. The remaining interest in LCH.Clearnet Group Ltd. is divided into 16.6% Redeemable Convertible Preference Shares (RCPSs) and 24.9% of total capital in the form of Ordinary shares.

On July 1, 2005, the Group contributed the assets and operations of LIFFE Market Solutions, the IT division of LIFFE to a newly formed company Atos Euronext Market Solutions Holding S.A.S. which resulted in a capital gain of € 5.0 million, after intercompany eliminations (see also paragraph 3.7).

Under the same agreement GL TRADE S.A. sold its 34.37% stake in Bourse Connect S.A. to Atos Euronext Market Solutions Holding S.A.S., which led to a capital gain of € 4.1 million, after intercompany eliminations (see also paragraph 3.7).

In July 2004, the Group received a cash payment of € 6.4 million relating to the disposal of its remaining 40% interest in Cote Bleue S.A., resulting in a capital gain of € 4.4 million.

Other gains and losses on sales of associates and activities in 2003 reflect the loss on voluntary liquidation of non-consolidated companies.

The 'Tax exempt income' reflects principally the income from associates and certain other tax-exempt investments. The non-deductible expenses in 2004 and 2003 principally consist of amortization and impairment of goodwill.

Part of the gain achieved from the sale of the Group's share in BCC/Clearnet in 2003 is subject to taxation at the moment of disposal of the Group's interest in LCH.Clearnet Group Ltd., for which a deferred tax liability of € 37.2 million is formed which is charged to 2003 income. The remainder of the gain is tax exempt.

The influence of the effect of participation exemption relates to the gain on the Group's share in the sale of BCC/Clearnet which is only partially tax exempt. Furthermore this item includes the Group's share in the losses of NQLX LLC for the period prior to its full acquisition in July 2003.

The French government has enacted legislation during 2004 through which the capital gains tax will be reduced in the years up to 2007. As a result thereof, the deferred tax positions of the Group have been restated in 2004, to reflect the expected tax rates when the related positions could be liquidated. This has resulted in a € 27.3 million reduction of income tax, which is reported as "Other" in 2004.

In 2004, the Group controlled GL TRADE S.A. through a 51.00% participation in Financière Montmartre, which held 55.61% of GL TRADE S.A. (resulting in a net investment of 28.36%). In addition, the Group held directly 12.00% of the share capital of GL TRADE S.A. (resulting in a net investment of 40.37%).

In accordance with an agreement to that extent (see also 3.6.5), in 2005 the Group acquired additional shares in Financière Montmartre in exchange for some of the GL TRADE S.A. shares held directly, resulting in a 54.77% participation in Financière Montmartre, a 9.91% direct investment in GL TRADE S.A. and a total investment in GL TRADE S.A. of 40.37%. Due to issuance of new shares by GL TRADE S.A. in 2005 for their stock option plans, the net investment of the Group was diluted to 40.18% at December 31, 2005.

Total	799,764	697,380	673,249

For 2005, impairment review of goodwill has been carried out in accordance with IAS36—Impairment of Assets.

The impairment tests of Cash Trading and Listing, Derivative Trading, Information Services and Settlement and Custody are based on the 2006 Budget, including conservative assumptions on volumes and control of expenses, business plan covering the period 2007-2010, and a maximum perpetual growth rate of 2% (Settlement and Custody 1%) after 2010. The pre-tax discount rate is 11.1% (except for Settlement and Custody 11.4%).

The impairment test of MTS is based on the 2006 Budget, including development in cash and money markets activities, a continuous strong growth of BondVision and a decrease in IT expenses, business plan covering the period 2007-2010 and a maximum perpetual growth rate of 2% after 2010. The pre-tax discount rate is 11.5%.

Based on the comparison between the sum of reported goodwill and intangible assets at year-end and the present value of future cash flows, no impairment loss has been recognized in that respect at December 31, 2005.

Goodwill on Sale of Software includes that arising from Euronext's acquisition of an additional 12% of GL TRADE S.A. shares in 2004 and the goodwill arising from GL TRADE S.A. acquisitions of operational subsidiaries.

•: The Euronext goodwill has been tested for impairment based on the fair value less cost to sell of the company. Based on the comparison between the reported goodwill and the market capitalization of the Group as at December 31, 2005, no impairment loss has been recognized in that respect at the closing date.
•: The goodwill on GL TRADE S.A.'s operational subsidiaries has been allocated to the respective cash generating units. The impairment tests of these cash generating units are based on the 2006 Budget and three-year forecasts 2007-2009 with a perpetual growth rate of 2.5% after 2009. The

Atos Euronext Market Solutions Holding S.A.S. (prior to July 1, 2005: AtosEuronext SBF S.A. SBF)

In 2005, the Group contributed its 50% stake in AtosEuronext SBF S.A. and the assets and operations of LIFFE Market Solutions (LMS), the IT division of LIFFE to Atos Euronext Market Solutions Holding S.A.S. in exchange for a 50% interest in that newly created company. While the Group holds a 50% interest in Atos Euronext Market Solutions Holding S.A.S., it does not control this associate (see also paragraph 3.7).

LCH.Clearnet Group Ltd.

Reported under 'acquisitions and capital contributions' in 2003 is the acquisition of a 32.5% participation in the Ordinary share capital of LCH.Clearnet Group Ltd. These Ordinary shares have been received in exchange for the Group's shares in BCC/Clearnet S.A. and London Clearing House that were contributed into LCH.Clearnet Group Ltd., a new entity that arose from the transaction done at December 22, 2003. The subsequent disposal of 7.6% of Ordinary shares is included under 'disposals'. The remaining 24.9% investment in LCH.Clearnet Group Ltd. (see table below) fully reflects the amount of goodwill paid.

Since the transaction of December 2003 was an intercompany transaction, an unrealized gain of € 65.3 million arising from this transaction is netted on the ordinary shares of LCH.Clearnet Group Ltd.

NASDAQ Liffe Markets Inc.

On July 24, 2003 the Group increased its interest in NQLX LLC from 50% to 100%. From that date the net assets of NQLX LLC are fully consolidated (see details below).

Short-term interest investments

This caption includes short-term time deposits with a maturity of more than three months from acquisition date and investments which are not readily convertible to cash or which are not subject to an insignificant risk of changes in value and therefore do not qualify as cash and cash equivalents.

Interest rate swap

The £250 million fixed-rate bonds maturing on June 16, 2009 (see also 3.2.12 financial liabilities) was swapped to floating rate using an interest rate swap designated as hedging the changes in the bond's fair value due to the changes in interest rates. The interest rate swap is recognized at fair value in the balance sheet with changes in fair value due to fluctuations in interest rates and currency rates booked in the income statement and substantially offset by the changes in fair value of the hedged bonds. In 2005, the fair value of the interest rate swap increased by €3.8 million (from a liability of €1.5 million), offsetting the positive adjustment of the hedged bond loan for the fair value fluctuation of the interest rate risk hedged.

Issued capital

The authorized share capital of Euronext amounts to € 200,000,000 representing 200,000,000 ordinary shares with a par value of €1 per share as of December 31, 2005, 2004, and 2003. Originally, 122,111,972 shares have been issued. Of these, 9,554,713 shares were cancelled at May 30, 2005.

The movement schedule for each of the reporting periods is as follows:

Number of shares outstanding as at 31 December	112,557,259		122,111,972	122,111,972

Share premium

The share premium at the end of the period reflects the difference between the value attributed to the shares received from SBF, BXS and AEX and the nominal value of the shares issued by Euronext. It also reflects the difference amounting to € 95 million between the market price (€ 20.63) of the Euronext shares at acquisition date of the BVLP shares and the par value of these Euronext shares. Due to cancellation of shares at the end of May 2005 (see also previous paragraph) the share premium decreased with the average share premium of € 9.60 for each cancelled share.

Reserve for own shares

The Reserve for own shares (treasury shares) include shares acquired under the share repurchase program and shares held in stock to cover the Group's employee stock option plans. The reserve includes any gain or loss that arises upon sale of treasury shares until the related program or stock option plan is finalized, when the resultant total gain or loss will be transferred to Retained earnings.

Share Repurchase Program

A decrease of the reserve of € 2.0 million during the reporting period relates to the transactions in Euronext shares made under the Share Repurchase Program. Transactions are conducted by the liquidity provider on behalf of the Group with the purpose of stabilizing the share price. As at December 31, 2005 Euronext holds 65,641 shares under the liquidity contract with a cumulative cost of € 0.6 million (December 31, 2004: 123,110 shares with a cumulative cost of € 1.4 million). Furthermore, starting on June 30, 2004, transactions were made under the program to buy back shares.

At May 30, 2005 Euronext cancelled 9,554,713 shares pursuant to this share buyback program, with a total cost of € 220.7 million. No additional shares were purchased under this part of the program in 2005, but withholding tax related to shares bought increased the cost of the repurchased shares by € 0.8 million.

The cancellation of the shares acquired under the Share Repurchase Program was registered with the AMF (the French securities supervisor) on May 9, 2005 under the authorization granted by the Annual General Meeting of May 26, 2004.

Exercise of options

As at December 31, 2005 the reserve for own shares comprises 1,270,841 shares (December 31, 2004: 1,453,388) held by Euronext's subsidiaries and 384,128 shares held by Stichting Option Plan SBF, a consolidated entity (December 31, 2004: 627,279). These shares are held in stock to cover the Group' employee stock option plans (see also 3.2.13 "Employee benefits").

In the reporting period, following the exercise of stock options held by employees, 215,970 shares were sold in relation to the SBF Stock Option Scheme, which resulted in a movement of € 1.2 million in the Reserve for own shares. In addition, 203,728 shares were sold in relation to the Euronext Stock Option Schemes 2001 and 2002, leading to a decrease of the Reserve for own shares of € 4.5 million. Finally, premature exercise on the Euronext Stock Option Scheme 2004 as allowed under certain conditions lead to a decrease of the Reserve for own shares of 6.000 shares at a total value of € 0.1 million (see also 3.2.13 "Employee benefits").

In addition, an amount of € 3.0 million was released from the reserve for currency exchange differences in relation to the impact of currency variations in the period prior to July 1, 2005 on assets and liabilities contributed to Atos Euronext Market Solutions Holding S.A.S.

Bond loan (non-current)

On February 9, 2004, the Group issued a £ 250 million 5.125% fixed-rate bond maturing on June 16, 2009 with a view to lengthening the profile and significantly reduce the cost of the Group's existing debt. The all-in cost of this financing, which was swapped to floating rate, amounts to 23 basis points over 3-month Libor, reported as interest expense. This bond does not contain any financial covenant or material customary provision, which may lead to an early redemption. It is recognized in the balance sheet at amortized cost, with directly related costs of issuing debt deducted from the amount of debt originally recognized and, together with transaction costs and issue premiums, amortized over the life of the debt using the effective interest rate of the transaction. The price risk affecting the fixed rate bond is hedged by an interest rate swap. The carrying amount of the bond is adjusted for gain or loss attributable to the hedged interest rate risk, with such gain or loss recognized in profit and loss and mostly offset by gain or loss from remeasuring the hedging swap at fair value through profit and loss. The carrying amount of the bond is also adjusted for change in €/£ currency rates with resulting gain and loss recognized in profit and loss. In 2005, the book value of the bond loan increased by € 14.3 million due to a € 0.3 million increase as a result of amortization in amortized costs, a € 3.8 million adjustment for the fair value fluctuation of the interest rate risk hedged (offset by an almost similar adjustment of the fair value of the interest rate swap hedging instrument (see note 3.2.8) and € 10.2 million currency revaluation.

Bank borrowings (non-current and current)

On June 24, 2004, GL TRADE S.A. entered into a five year banking facility agreement for an amount of €15 million. This facility is indexed on Euribor with a floor rate, falls due on June 24, 2009 and includes a capital redemption of € 3 million per year. As at December 31, 2005, the outstanding facility amounts to

€ 12 million of which € 3 million are classified as current loans and borrowings. No guarantees were provided for this loan.

In November 2001, Euronext (UK) plc entered into a credit facility agreement for an amount of € 409 million (£ 250 million) to partly finance the acquisition of LIFFE (Holdings) plc. At December 31, 2003, the remaining balance of this loan becoming due and repayable on November 12, 2004 was booked in the current loans and borrowings for an amount of € 213 million (£ 150 million). No guarantees were provided for this loan. On February 12, 2004, the Group fully repaid this outstanding £150 million banking loan following the issue of a £250 million fixed-rate bond maturing on June 16, 2009 (see also note above).

Loan notes (current)

In connection with the acquisition of LIFFE, the Group also issued variable rate guaranteed unsecured loan notes redeemable at the holders' request or on January 7, 2007 at the latest. The outstanding loan notes are reported in the current loans and borrowings for €5.7 million (£3.9 million).

Put options granted to minority shareholders

GL TRADE S.A. has granted put options to minority shareholders of the companies Glesia and GL TRADE America Inc., which GL TRADE S.A. controls. The present value of the exercise price of the option (€4.9 million and €1.0 million respectively) is reflected as a financial liability.

Euronext and Borsa Italiana S.p.A. through MBE Holding S.p.A. have subscribed to 51% of MTS share capital on November 18, 2005. As a result of the pre-emptive rights and sale mechanism, MBE Holding S.p.A. is committed to acquire an additional stake in the controlled MTS of 9.37%. The Euronext share in the commitment, €12.6 million, is reflected as a financial liability.

Euronext has granted Borsa Italiana S.p.A. a put option on its 49% stake in MBE Holding S.p.A., the 51/49% Euronext/Borsa Italiana S.p.A. holding company controlling MTS. The option is exercisable at any time until 2010. As MBE Holding S.p.A. is jointly controlled by the Group and Borsa Italiana S.p.A. and is proportionally consolidated at 51% by the Group, the put option is treated as a derivative financial instrument. The fair value of this option is determined as being the difference between the estimated exercise price and 49% of the enterprise value determined on the basis of a discounted cash flow method. When the exercise price exceeds the enterprise value, a liability is recognized. At December 31, 2005, as the exercise price did not exceed the enterprise value, no liability was required to be recognized.

Interest rate swap

The £250 million fixed-rate bonds maturing on June 16, 2009 (see also 3.2.8 short-term financial investments) was swapped to floating rate using an interest rate swap designated as hedging the changes in the bond's fair value due to the changes in interest rates. The interest rate swap is recognized at fair value in the balance sheet with changes in fair value due to fluctuations in interest rates and currency rates booked in the income statement and substantially offset by the changes in fair value of the hedged bonds. In 2004, the fair value of the interest rate swap moved from zero at inception to a liability of € 1.5 million at year end, offsetting the opposite adjustment of the hedged bond loan for the fair value fluctuation of the interest rate risk hedged.

Fair value of services received in return for share based payments

The fair value of services received in return for shares and stock options granted is measured by reference to the fair value of shares and stock options granted. The estimate of the fair value of the services received is measured based on the binomial pricing model. The contractual lives of the stock options are used as input into this model, as are expectations of early exercise.

Fair value of stock options and assumptions:

Risk-free interest rate (2)	3.1	%	2.8	%	2	%	2	%

(1): Expressed as weighted average volatility used in the modeling under binomial pricing model
(2): Based on national government bonds

The expected volatility is based on the historic volatility (calculated based on the weighted average remaining life of the stock options), adjusted for any expected changes to future volatility due to publicly available information.

Stock options under Euronext Stock Option Scheme 2004 are granted under a service condition and a non-market performance condition. Such conditions are not taken into account in the grant date fair value measurement of the services received. There are no market conditions associated with the stock option grants.

The fair value of the shares granted under the Executive Incentive share plan at grant date of € 34.33 is determined based on the Black-Scholes formula. The model inputs are the share price of € 36.08, expected dividends of 1.7 per cent, a term of three years with an additional two year retention period and a risk-free interest rate of 2.5 per cent.

3.3 NOTES TO THE CONSOLIDATED CASH FLOW STATEMENTS

The cash flow statement provides information about the cash flows in order to analyze the changes in the net assets of the Group, its financial structure and its ability to affect the amounts and timing of cash flows.

Cash flows arising from transactions in foreign currency are recorded by applying the exchange rate at the date of the transaction or the average rate as far as the cash flows in foreign currency relate to the operating activities. The effect of the exchange rate changes is shown separately in the cash flow statement, in order to reconcile with cash and cash equivalents at the end of the year.

Any part of operating, investing or financing transactions that does not require the use of cash or cash equivalents has been excluded from the cash flow statement. For that reason, reported line items in the income statement may vary from the actual cash flow related to that component as reported in the cash flow statement.

3.3.1 Cash flows from operating activities

"Operating activities" are the principal revenue-generating activities of the Group. The cash flows from operating activities are shown according to the indirect method whereby net profit or loss is adjusted for the effects of transactions of a non-cash nature, any deferrals or accruals of past or future operating cash receipts or payments, and items of income or expense associated with investing or financing cash flows.

3.4 SEGMENT REPORTING

The Group's risks and returns are predominantly managed by business units. The primary format for reporting segment information therefore is by business segments.

The Group generally accounts for intersegment sales as if transfers were made to third parties at current prices (arm's length). The geographical segments are regarded as the secondary segmentation of reporting of the activities of the Group.

Business segments (primary segmentation)

The Group comprises the following main business segments (further reference is made to the Report of the Managing Board):

•: Cash Trading: the management of trading in all cash instruments (stocks, bonds and structured products such as warrants, certificates and exchange traded funds).
•: Listing: the listing of all cash instruments as mentioned above.
•: Derivatives Trading: the management of trading in a wide range of derivatives products.
•: MTS Fixed Income: the management of trading in bonds and repos, etc.
•: Information Services: the sale of market data and related information.
•: Settlement & Custody: the settlement of transactions and the safe-custody of physical securities.
•: Sale of Software: the providing of electronic trading solutions.

3.5 DISCONTINUED OPERATION

For 2005 and 2004, all income results from continued operations.

On 25 June 2003, the Boards of Euronext, BCC/Clearnet S.A. and London Clearing House Ltd. (LCH) announced their intention to merge BCC/Clearnet S.A. and LCH under a new independent UK holding company called LCH.Clearnet Group Ltd.

On 22 December 2003, the Group exchanged its stake in the share capital of BCC/Clearnet S.A. to LCH.Clearnet Group Ltd. and 17.7% of LCH in exchange for 49.1% of the newly formed company. Simultaneously, the Group sold 7.6% of these shares to third parties. The remaining interest in LCH.Clearnet Group Ltd. is divided into 16.6% Redeemable Convertible Preference Shares (RCPS) and 24.9% of total capital in the form of Ordinary shares. The preference shares are intended to be either redeemed or converted into Ordinary shares or to be sold in the coming years. Accordingly, despite the continued involvement with LCH.Clearnet Group Ltd. through its shareholding in Ordinary shares and RCPS, the Group considers the sale as a discontinued operation.

BCC/Clearnet S.A., established as a credit institution under French law, was the sole clearing house and central counterparty for markets operated by Euronext (excluding Euronext.Liffe). BCC/Clearnet S.A. cleared trades for Powernext and also cleared debt securities and repos for other providers. The net assets, results and cash flows of BCC/Clearnet S.A. were fully consolidated in the Euronext consolidated accounts in the period prior to 22 December 2003. As of that date, assets and liabilities of BCC/Clearnet S.A. have been deconsolidated.

The effect of the discontinued clearing activities of BCC/Clearnet S.A. on the Group's consolidated results, cash flows and net assets in 2003 is analyzed as follows:

	Continued Operations 2003		Discontinued Operations 2003		Total 2003

3.6 FINANCIAL RISKS, OFF-BALANCE SHEET COMMITMENTS AND CONTINGENT LIABILITIES

3.6.1 Financial risks

As a result of its global operating and financing activities, the Group is exposed to financial risks such as changes in interest rates, changes in currency exchange rates or risk that a counterparty defaults. Strict policies and procedures to measure, manage, monitor and report risk exposures have been defined and are regularly reviewed by the relevant management and supervisory bodies (Risk committee, Managing Board, Audit Committee as appropriate).

The proper identification and the daily monitoring and management of risks are carried out by a central treasury and financing department in accordance with rules and procedures in force. When allowed

FIN-167

EURONEXT N.V.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

by local regulations and when necessary, the Group's subsidiaries centralize their cash investment, report their risks and hedge their exposures with the Group's central treasury. Derivative instruments are solely used to hedge financial risks incurred in the normal course of the Group's commercial activities or financial positions. The Group does not enter into derivative instruments for speculative purposes.

3.6.1.1 Liquidity risk

The Group would be exposed to a liquidity risk should its short term financial liabilities become, at any date, higher than its short term financial assets and in the event that the Group were not able to refinance this cash deficit, for example through new banking lines.

The Group's policy is to invest cash, cash equivalents and short term financial investments into non-speculative financial instruments, readily convertible to cash, such as money market funds, overnight deposits, term deposits and other money market instruments, thus ensuring a very high liquidity of its financial assets.

More specifically, the Group's short term financial assets position allows the company to repay its financial liabilities at all maturities, even disregarding incoming cash flows generated by operational activities. The net position at various maturities of the financial assets and liabilities as of December 31, 2005 is described in the table below:

(1): Fixed rate to floating rate swap hedging the fixed rate bond
(2): Including € 105 million fixed rate short-term deposits swapped to floating rate
(3): Government bonds

As a result, the Group is not exposed to price risk affecting fixed-rate financial assets and liabilities.

However, the Group is exposed to cash-flow risk arising from net floating-rate positions. As the Group is lender at floating rate in euro, when euro rates decrease, the financing income of the Group, which is lender at floating-rate in euros, decreases (€3.8 million for a 1% decrease). Similarly, as the Group is borrower at floating rate in pounds sterling, when the sterling rates increase, the financing expenses of the Group increase (€ 0.9 million for a 1% increase).

Over-the counter interest rate derivative instruments, such as swaps, are contracted with counterparties meeting minimum creditworthiness and rating standards within predetermined limits.

3.6.1.3 Currency risk

Further to the acquisition of LIFFE (Holdings) plc., a significant part of the assets, liabilities, income and expenses of the Group is recorded in pounds sterling. Therefore, the Group is exposed to a currency risk. When the euro increases in value against the pound sterling, the contribution of equity, being the balance of assets and liabilities, and income in pound sterling, once translated into euros, in the consolidated financial statements of the Group decreases.

The evolution of the price of pound sterling during the periods was as follows:

	2005	2004	2003
	In euro
Price of a pound sterling at the beginning of the year	1.41834	1.41880	1.53730
€/£ rate at the beginning of the year	0.7051	0.7048	0.6505
Price of a pound sterling at the end of the year	1.45922	1.41834	1.41880
€/£ rate at the end of the year	0.6853	0.7051	0.7048
Average price in the reporting period	1.46198	1.47359	1.44564
Average €/£ rate in the reporting period	0.6840	0.6786	0.6917

The net currency position of the Group in the reporting periods is summarized as follows:

		2005	2004	2003
		In pound sterling millions
Net currency position at 31 December		284	274	319
	of which in assets(1)	579	586	562
	of which in liabilities	295	312	243
Borrowings in pound sterling		254	255	156

(1): Including £ 291 million goodwill in 2005 (2004: £ 289 million, 2003: £ 306 million)

The borrowings in pounds sterling constitute a partial hedge of the net assets in pounds sterling. The cost of this hedge in the financing income consists of the difference between the interest rate in pound sterling and the interest rate in euro. No other hedge of balance sheet currency position was implemented on the respective balance sheet dates.

The currency exchange rate differences had a positive impact of € 12.5 million on the Group's consolidated equity in 2005 (2004: € 4.8 million, 2003:-€ 40.9 million). The sensitivity of the cumulative exchange rate difference (€ -41.1 million as at December 31, 2005, € 54.0 million as at December 31, 2004, € 58.8 million as at December 31, 2003) to a 1 cent variation of the exchange rate (for example 0.6953 instead of 0.6853) is € -6.0 million (2004: € 5.4 million, 2003: € 6.3 million).

In order to reduce its exposure to foreign exchange rate fluctuations, the Group may use derivative financial products, however exclusively to hedge financial risks incurred by its commercial activities or financial positions.

3.6.1.4 Credit risk of financial instruments

The Group is exposed to credit risk in the event of a counterparty's default. The Group limits its exposure to credit risk by rigorously selecting the counterparties with which it executes agreements. Credit risk is monitored by using exposure limits depending on ratings assigned by rating agencies as well as the nature and maturity of transactions. Investments of cash and cash equivalents in bank current accounts and money market instruments, such as short term fixed and floating rate interest deposits, are strictly restricted by rules aimed at reducing credit risk: maturity of deposits is less than six months, counterparties' credit ratings are permanently monitored and individual counterparty limits are reviewed on a regular basis.

In addition to the intrinsic creditworthiness of counterparties, the Group's policies also prescribe the diversification of counterparties (banks, financial institutions, funds) so as to avoid a concentration of risk.

Off-balance sheet derivatives are negotiated with leading high-grade banks.

3.6.1.5 Settlement and custody risks

Non-core activities of the Group include the Settlement and Custody services provided by CIK S.A./N.V. and Interbolsa S.A., which are the central security depositories for Belgium and Portugal.

As at December 31, 2005, the value of securities kept in custody by CIK S.A./N.V. and Interbolsa S.A. amounted to € 376 billion (December 31, 2004: €320 billion, December 31, 2003: € 280 billion), based on the market value of shares and the nominal value of bonds.

The procedures of these subsidiaries are focused on safeguarding the assets in custody. The settlement risks are mitigated by early warning systems for non-settlement, and buy-in and auction procedures in case certain thresholds are surpassed.

3.6.1.6 Equity Market risk

The main position of the Group consists of an investment in Atos Origin of €18.1 million (2004: € 16.2 million, 2003: € 22.2 million). This position is monitored and reported to the Group's senior management on a daily basis.

3.6.2 Legal Proceedings

Via Net.Works Inc.

Following the IPO of Via Net.Works Inc. on Euronext Amsterdam market and Nasdaq on 11 February 2000, Euronext Amsterdam market was criticized by the media for allowing trading in shares of Via Net.Works Inc. to start before trading started on Nasdaq. Prior to the start of trading of these shares on Nasdaq, trading on Euronext Amsterdam market opened and closed at a price of €89 per share. After the close of trading on the Amsterdam market, trading on Nasdaq opened at a price of $41 per share. At the start of the next trading day, Via Net.Works Inc. price on the Amsterdam market dropped to €50 per share. The STE (the Dutch Securities Supervisor and predecessor of the AFM) conducted an inquiry into the listing of Via Net.Works. In 2002, the AFM notified Euronext Amsterdam that it had decided not to fine or sanction the company in connection with this initial public offering. This decision is final.

Following the initial public offering, legal proceedings were instituted against the Amsterdam Exchanges N.V., the predecessor of Euronext Amsterdam by a private investor and the Via Net.Works Foundation, claiming to represent approximately 600 investors and currently claiming compensation in respect of trading losses of approximately €11 million. Euronext Amsterdam is strongly defending itself against these claims. The private investor claim (€250,000) and Foundation claim were both dismissed by the District Court of Amsterdam. Appeals were filed by the parties with the Amsterdam Court of Appeals and judgment is pending in both cases.

NCP

To date, 48 dealers on the French derivatives markets (NCPs) have issued a similar claim on several dates against Euronext Paris before the Paris Commercial Court, claiming damages due to the malfunction of the derivative IT platform at the time of the migration from floor to screen trading, and also to the development of automated price injection models, which strongly reduced their own activity.

Damages claimed to date total 73.8 million euros. Since the basis of the claim and its legal grounds are considered unclear, no provision is recorded at December 31, 2005.

Trading Technologies

Furthermore, the Group's subsidiary GL TRADE S.A. is involved in a litigation initiated by Trading Technologies in the U.S., which also concerns other companies in the same industry as GL TRADE S.A. The claimed amount is not communicated by the plaintiff yet. GL TRADE S.A., a company created many years before Trading Technologies, considers itself to have a strong "prior art" to be used in its defense. Consequently, GL TRADE S.A. has not recognized a provision at December 31, 2005.

3.6.3 Taxes

The Group is organized along business units. Each business unit is managed from one of the Group's locations and has cross-border responsibilities. As a consequence of this cross-border functioning, some business unit tasks are centralized and business unit support is given from one location to another for the benefit of the Group as a whole. As a result of the close interrelation of the business unit operations in the various countries, the reported income per individual Group company entity may not necessarily be a justified basis for determining the taxable result. For this reason the Group obtained an advance pricing agreement with the relevant fiscal authorities for its activities in Belgium, France and the Netherlands in 2004. Approval has been obtained for the advance pricing agreement effective retrospectively from 2001 to 2005. The Group is in the process of extending the current advance pricing agreement with the UK and Portuguese authorities with effect from 2004 and 2005. Further, the Group has filed a request with the relevant fiscal authorities to renew the advance pricing agreement for tax years 2006 through 2010. The objective is a fair allocation of the results of the Group for these countries to be based on both local tax law and the OECD Pricing Guidelines for Multinational Enterprises and Tax Administrations. For its transfer pricing methodology the Group has opted to split the profit by business unit between the countries.

In 2005, the tax due has been calculated as if the envisaged extension of the APA was already in force.

3.6.4 Operating leases

Non-cancellable operating lease rentals are payable as follows:

	2005	2004	2003
	In thousands of euros
Less than one year	11,613	2,322	4,772
Between one and five years	3,277	12,586	14,640
More than five years	9,406	10,804	9,632

TOTAL	24,296	25,712	29,044

The Group leases land, equipment and office facilities under operating lease. The leases typically run for an initial period of three to ten years, with an option to renew the lease after those dates. Lease payments are usually increased annually to reflect market rentals.

None of the leases includes contingent rentals. No significant assets were pledged other than the operating leases described above.

3.6.5 Contingent liabilities

Legal framework related to Financière Montmartre

By acquiring 10% of the shares previously held by Reuters in 2004, Euronext has reinforced its investment in GL TRADE S.A. On this occasion the existing legal framework was modified in order to redefine the relationship between the shareholders in Financière Montmartre. This entity holds 55.36% in the share capital of GL TRADE S.A. and is owned by Euronext (54.77%) and the founders of GL TRADE S.A. These modifications manage any possible future liquidity requirement of the founders of GL TRADE S.A. and could lead to a fluctuation of Euronext's investment in GL TRADE S.A. GL TRADE S.A. founders are granted a put option on up to 10.5% of GL TRADE S.A. capital share. The option has no termination date and can be exercised at any moment after 28 February 2006. The exercise price has been set at the average market value of the previous 40 trading days, less 1 euro.

3.8 SUBSEQUENT EVENTS

Share capital repayment

In the Financial Statements 2005, as part of the published Registration Document and Annual Report 2005, Management and Supervisory Board recommended an additional dividend of € 3.00 per qualifying ordinary share to be submitted for approval by the Annual General Meeting. This repayment to shareholders would preferably be executed by means of a share capital repayment and was presented as such to the Annual General Meeting.

The Annual General Meeting of 23 May 2006 approved upon a share capital repayment of € 3.00 per qualifying ordinary share. Prior to the repayment in August 2006, share capital will be increased to € 9.00 per share by means of a transfer from share premium.

3.9 EFFECT OF ACQUISITIONS, CONTRIBUTIONS AND DISPOSALS

3.9.1 ACQUISITIONS

ACQUISITIONS 2005

The impact of the acquisitions made during the year 2005 (see note 2 "Changes in the scope of consolidation") is detailed below. Acquisitions relate to MBE Holding S.p.A., MTS S.p.A., CScreen Ltd. and OASIS Inc.

Change in initial recognition

Within twelve months of the acquisition date in 2004, as required by IFRS3 "Business Combinations", GL TRADE S.A. has finalized the allocation of the cost of business combinations and accounted for separately the acquired identifiable assets, liabilities and contingent liabilities that meet the recognition criteria at their fair value at acquisition date.

For the companies Ubitrade SA and Davidge Inc, GL TRADE S.A. has identified intangible assets representing "customers relationships" (fair valued at € 2.7 million and € 0.3 million, respectively) and "technology" (fair valued at € 0.5 million and € 0.1 million). The related depreciation amounts to € 0.5 million in 2005. In addition, GL TRADE S.A. has identified intangible assets representing a "Customer portfolio" of Fermat's distribution business (fair valued at € 3.6 million). The related depreciation amounts to € 1.9 million in 2005.

A deferred tax liability has been recognized on the fair value of these intangible assets.

Moreover, tax losses of certain acquired subsidiaries have been recognized as deferred tax assets during 2005 for € 3.2 million leading to a decrease of the initial goodwill. The use of these tax losses in 2005 has no impact on the Income Statement since the related decrease of the income tax is compensated by the reversal of the deferred tax assets.

3.14 Summary of differences between International Financial Reporting Standards and United States Generally Accepted Accounting Principles

The consolidated financial statements of Euronext Group have been prepared in accordance with International Financial Reporting Standards ("IFRS") as described in Note 2. to the consolidated financial statements.

IFRS differ in certain significant respects from accounting principles generally accepted in the United States of America ("U.S. GAAP").

The application of U.S. GAAP would have affected the Group's consolidated net income attributable to shareholders of the parent company for the fiscal years ended December 31, 2004 and 2005 and its shareholders' equity as of December 31 2004 and 2005 as provided in the tables below.

3.14.3: Description of differences between accounting principles applied to prepare the consolidated financial statements under IFRS and U.S. GAAP

A—Business Combinations

Under IFRS, goodwill and acquired identifiable intangible assets were amortized ratably to earnings over their estimated useful lives. The Group adopted IFRS 3 for all business combinations agreed on or after March 31, 2004 and consequently did not amortize goodwill on acquisitions made after March 31, 2004. Starting January 1, 2005 the Group no longer amortizes goodwill relating to acquisitions made before March 31, 2004. When necessary, goodwill impairment charges are reported in earnings with a corresponding reduction in the carrying value of goodwill.

Under U.S. GAAP, goodwill acquired in business combinations occurring prior to June 30, 2001 was capitalized and amortized on a straight-line basis over its estimated useful life with respect to business combinations completed prior to June 30, 2001. In its application of U.S. GAAP, the Group first applied the provisions in Statement of Financial Accounting Standards ("SFAS") No. 141 "Business Combinations" ("SFAS 141") and SFAS No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142") for business combinations initiated after June 30, 2001. From January 1, 2002, the provisions of SFAS 142 were also applied to goodwill and other intangible assets acquired prior to June 30, 2001. Since the adoption of SFAS 141 and SFAS 142 goodwill and indefinite life intangible assets are no longer amortized, but instead tested, at least annually, for impairment.

The significant transactions which were revisited for U.S. GAAP purposes include the merger between the Amsterdam, Brussels and Paris exchanges in 2000, the acquisitions of Liffe and BVLP in 2002, the acquisition of MTS in 2005 and the acquisition of a further 10% stake in GL TRADE in 2005, as well as the Atos Euronext, AEMS and LCH.Clearnet transactions.

Under U.S. GAAP the impairment test for intangible assets subject to amortization is conducted in two steps. The first step is to compare the carrying amount to undiscounted future cash flows. If the carrying amount is higher than the sum of the undiscounted cash flows, the second step is to calculate the impairment based on discounted cash flows expected from the use and eventual disposition of the asset. For intangible assets not subject to amortization, the impairment test consists of a comparison of the fair value of the intangible asset to its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The schedule below reflects the impact of the adjustments from IFRS to U.S. GAAP as at December 31, 2004 and December 31, 2005 for the above mentioned business combinations and the effect of the adjustments mentioned below in Notes J and K.

		December 2005	December 2004	Estimated Useful Life
		In thousands of euros
Decrease in goodwill		399,450	313,250
Increase in:
	Regulatory licenses	435,325	431,135	Indefinite
	Customer relationships	197,326	208,177	20 years
	Trade marks	27,514	26,795	Indefinite
	Technology	5,977	7,409	3 to 6 years
Total other intangibles (including goodwill)		266,692	360,266
Increase in deferred tax liabilities on intangibles		203,660	215,835

B—Admission fees

The Group collects admission fees from issuers that first offer their securities for trading in the public market.

The Group immediately recognizes such fees as revenue under the guidance in IAS 18, "Revenue" when an issuer's securities are first listed. U.S. GAAP interpretation provided by the Securities and Exchange Commission ("SEC") reflected in the SEC Staff Accounting Bulletin No. 104, "Revenue Recognition," requires recognition of those admission fees over the period in which the services are provided. Accordingly, under U.S. GAAP, the Group recognizes admission fees on a straight-line basis over the estimated service periods of 10 years.

C—Derivatives and hedging

Under IFRS, the Group incurred a £250 million denominated fixed-rate debt obligation in February 2004 that was economically swapped into a floating rate liability using an interest rate swap that was designated by management as a fair value hedge of interest rate risk in accordance with IAS 39, "Financial Instruments." Under the fair value hedge both the qualifying portion of the debt and the interest rate swap contract are carried at fair value with changes in fair value being reported in earnings.

The documentation established for IAS 39 purposes does not comply with U.S. GAAP requirements because the prospective effectiveness assessment under IAS 39 is documented by analyzing the critical terms of the swap and the bond which is not permitted under U.S. GAAP. As a result, for U.S. GAAP purposes, this interest rate swap does not qualify as a hedging instrument. Therefore, the bond remains reported as amortized cost and the swap is recognized as a trading derivative which is marked to market at each reporting period through earnings.

D—Financial instruments

Under IFRS, Euronext's current investments in equity shares and Money Market Funds have been designated by management at the date of initial recognition as "Financial assets at Fair Value through profit and loss" ("the fair value option") in accordance with IAS39.9 Accordingly, as disclosed in Note 4.2 to the Group's consolidated financial statements, unrealized gains and losses on these securities are reported in earnings.

Under U.S. GAAP, SFAS 115 does not allow an entity to apply the IFRS "Fair value option" and these investments are reported as available for sale (AFS) securities at fair value under SFAS 115, "Accounting for Investments in Debt and Equity Securities," with unrealized gains and losses being reported in stockholders' equity net of their related tax consequences.

E—Foreign currency exchange gains and losses on available for sale debt securities

Under U.S. GAAP, under the guidance in EITF 96-15 "Accounting for the Effects of Changes in Foreign Currency Exchange Rates on Foreign-Currency-Denominated Available-for-Sale Debt Securities," as amended by SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," changes in value of AFS securities that result from changes in foreign currency exchange rates are reported in shareholder's equity and transferred to earnings as a component of gain or loss only upon sale of the instrument.

F—Employee benefits

Under IFRS and as disclosed in Note 4.2 to the consolidated financial statements accounting for pensions and other post-employment benefits is made in accordance with IAS19, "Employee Benefits." The Group's net obligation is measured by estimating future benefits employees have earned. Pension and benefit costs are recognized in earnings over the service periods.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The significant differences between IAS 19 and U.S. GAAP under SFAS 87, "Accounting for Pensions", SFAS 88, "Accounting for Pension Settlements and Curtailments", SFAS 106, "Accounting for Postretirement Benefits", and SFAS 112, "Employers' Accounting for Post-Employment Benefit" that affect the Group are:

•: Different dates of implementation for the parent company of the Group caused most of the differences in the accumulated actuarial gains and losses. For the acquired entities, both IAS 19 and U.S. GAAP have been implemented since the acquisition date.
•: Under IAS 19, the past service costs resulting from plan amendments were recognized immediately if vested or amortized over the remaining vesting period. Under U.S. GAAP, prior service costs are generally recognized over the average remaining service life of the plan participants affected by the amendments.
•: In addition, under U.S. GAAP, an additional minimum liability should be recognized if the positive difference between the accumulated benefit obligation and the fair value of the plan assets is greater than the accrued liability. The additional minimum liability is recognized and an intangible asset is recognized for an amount not exceeding the amount of unrecognized prior service cost. If the additional minimum liability required to be recognized exceeds unrecognized prior service cost, the excess is reported as a reduction of other comprehensive income. Such an additional minimum liability is not recognized under IAS 19.

The effect of these differences on shareholders' equity can be summarized as follows:

	December 31
	2005		2004
	Thousands of euros
Accumulated actuarial gains and losses	(4,173	)	(3,484	)
Unrecognized prior service cost	—		3,437
Additional Minimum Pension Liability	(17,270	)	(14,267	)

U.S. GAAP adjustment	(21,443	)	(14,314	)

G—Share-based payments

In accordance with IFRS2 "Share-based Payment," Euronext recognized compensation expenses for all share-based programs that were granted after November 7, 2002. An estimated cost for the granted instruments, based on the instruments' fair value at grant date and the number of instruments expected to vest is charged to the income statement, with a corresponding increase in equity or liabilities if the award is cash-settled, over the vesting period on a straight line basis. The fair value of the options is measured using a binomial model, taking into account the terms and conditions upon which the options were granted. As of December 31, 2005, there are no grants outstanding which would require cash settlement.

Under U.S. GAAP, Euronext applies the intrinsic value method in accordance with Accounting Principles Board Opinion 25, "Accounting for Stock Issued to Employees" ("APB 25") for share-based programs with employees, including those plans prior to November 7, 2002, and the plans are either classified as fixed or variable plans. Under APB 25, compensation expense is determined, using the intrinsic value method, as the difference between the market price and the exercise price of the share-based award. For fixed plans compensation expense is determined on the grant date. For variable plans compensation is remeasured at each balance sheet date until the award becomes vested.

H—Software Revenue Recognition

Under U.S. GAAP, the rules for revenue recognition under multiple-element arrangements are detailed and prescriptive. These rules include the requirement that revenues be allocated to the respective elements of such an arrangement on the basis of Vendor Specific Objective Evidence ("VSOE") for each element. Statement of Position ("SOP") 97-2 "Software Revenue Recognition" sets out precise requirements for establishing VSOE for valuing elements of certain multiple-element arrangements. When VSOE for individual elements of an arrangement cannot be established in accordance with SOP 97-2, revenue is generally deferred and recognized over the term of the final element.

Under U.S. GAAP, the Group did not have VSOE for certain elements of certain multiple-element arrangements with customers within the LIFFE business. The terms of these arrangements with customers include, among other terms, the provision of hosting services and on-going customer support (known as Post-contract customer support, or PCS, under SOP 97-2). As a consequence of the terms of these arrangements, revenue is deferred under U.S. GAAP and does not start to be recognized until delivery or discharge of the obligation in respect of the final element of the arrangement for which VSOE is not determinable. If this final element is PCS, then revenue is recognized over the remaining term of the PCS contract.

I—Other

This reconciling item mainly reflects U.S. GAAP adjustments at GL Trade and AEMS mainly related to goodwill amortization, revenue recognition, and restructuring liabilities.

J—Put options granted to minority interests

Under U.S. GAAP, these put options are recorded as liabilities measured initially at fair value and consequently with changes in fair value recognized into earnings.

K—MBE Holding

Under IFRS, MBE Holding is being consolidated under the proportional consolidation method.

Under U.S. GAAP, it was determined that MBE Holding should be accounted for under the equity method primarily because the minority shareholder holds significant participating rights.

Amounts reflected in the Group's consolidated balance sheet under IFRS with respect to MBE Holding include current assets of € 19.5 million, non-current assets of € 70.0 million, current liabilities of € 10.2 million and non-current liabilities of € 1.1 million as of December 31, 2005.

Cash Flow statement

3.14.4 Recently issued accounting pronouncements

On December 16, 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004), "Share-Based Payment" (SFAS 123R), which is a revision of SFAS 123. SFAS 123R supersedes APB 25, and amends SFAS No.95, Statement of Cash Flows (SFAS 95). SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative.

The company adopted this new standard on January 1, 2006, using the modified prospective method. Under the modified prospective method, share-based compensation is recognized based on the fair value of the awards for:

•: New share-based payment awards granted;
•: Awards modified, repurchased, or cancelled after the required effective date; and
•: The remaining portion of the requisite service under previously-granted unvested awards outstanding as of the required effective date.

The main effect of adopting the standard on January 1, 2006 concerns Euronext stock option award granted in 2004. Under FAS 123 (R), Euronext stock option award granted in 2004, which is currently classified as an equity instrument under APB 25, will be classified as a liability. This liability will be recognized at its fair value of €6 million at January 1, 2006 by reducing equity. The difference between the fair value of the liability recognized at January 1, 2006 and the previously recognized compensation cost until that date amounts to €0.2 million and will be recognized in the income statement, net of any related tax effect, as the cumulative effect of the change in accounting principle.

On June 7, 2005, the FASB issued Statement N^o154, Accounting Changes and Error Corrections, a replacement of APB Opinion N^o20, Accounting Changes, and Statement N^o3, Reporting Accounting Changes in Interim Financial Statements. Statement 154 changes the requirements for the accounting for and reporting of a change in accounting principle. Previously, most voluntary changes in accounting principles required recognition via a cumulative effect adjustment within net income of the period of the change. Statement 154 requires retrospective application to prior periods' financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. Statement 154 is effective for accounting changes made in fiscal years beginning after December 15, 2005; however, the Statement does not change the transition provisions of any existing accounting pronouncements. Management does not believe adoption of Statement 154 will have a material effect on its consolidated financial position, results of operations and cash flows.

WHEREAS, in furtherance thereof, the parties hereto propose that, upon the terms and subject to the conditions set forth in this Agreement: (a) Holdco (or a wholly owned Subsidiary of Holdco) shall make an offer (the "Offer") to acquire all of the issued and outstanding shares, nominal value €1 per share (it being understood that the nominal value may change as a result of proposal 3(e) of the annual general meeting of Euronext held on May 23, 2006 regarding the Special Euronext Distribution), of Euronext (the "Euronext Shares"), for a combination of shares of common stock, par value $0.01 per share, of Holdco ("Holdco Common Stock") and cash; and (b) concurrently with the purchase by Holdco (or a wholly owned Subsidiary of Holdco) of the Euronext Shares pursuant to the Offer, Merger Sub shall merge with and into NYSE Group, with NYSE Group surviving the merger as a wholly owned subsidiary of Holdco (the "Merger"), and, in the Merger, each share of NYSE Group Common Stock shall be converted into the right to receive one share of Holdco Common Stock;

WHEREAS, the parties agree that, prior to the consummation of the Offer and the Merger, Euronext shall be permitted to pay to the Euronext shareholders its previously announced special distribution (or a reduction of capital if such reduction shall not delay the commencement of the Offer) of €3 per Euronext Share (the "Special Euronext Distribution");

WHEREAS, the respective Boards of Directors of NYSE Group, Holdco and Merger Sub have each determined that the Merger and the Offer and the other transactions contemplated by this Agreement are consistent with, and will further, the respective business strategies and goals of its company, and are in the best interests of their respective company's stockholders and, therefore, have approved the Offer, the Merger, this Agreement and the transactions contemplated by this Agreement;

WHEREAS, the Supervisory Board and the Management Board of Euronext (together, the "Euronext Boards") have each determined that the Merger and the Offer and the other transactions contemplated by this Agreement are consistent with, and will further, the business strategies and goals of Euronext, and are in the best interests of Euronext, its shareholders, employees and other stakeholders and, therefore, have approved the Offer, the Merger, this Agreement and the transactions contemplated by this Agreement;

ARTICLE I

THE OFFER

Section 1.1. The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Article IX, and subject to the prior satisfaction or waiver of the conditions set forth in Annex II hereto, as promptly as practicable, Holdco shall (or shall cause another direct or indirect wholly owned Subsidiary of Holdco to) file the Offer with the French Financial Market Authority (Autorité des Marchés Financiers) (the "AMF") within the meaning of the General Rules of the AMF, as may be amended from time to time (the "GRAMF", which term shall be deemed to include any other relevant rules, instructions and/or recommendations of the AMF). Following approval by the AMF of the terms of the Offer and the Tender Offer Prospectus (Note d'Information), Holdco shall commence, within the meaning of the GRAMF, the Offer to exchange each Euronext Share for 0.98 of a share of Holdco Common Stock (the "Standard Stock Amount") and €21.32 in cash (the "Standard Cash Amount" and, together with the Standard Stock Amount, the "Mixed Offer Consideration" (offre mixte principale)) with an option to receive in the Offer, in lieu of the Mixed Offer Consideration, the Stock Election Consideration (in the offre d'échange subsidiaire) or the Cash Election Consideration (in the offre d'achat subsidiaire), as each may be adjusted pursuant to this Section 1.1. In the event that Holdco shall cause a Subsidiary of Holdco to file and commence the Offer, each reference to Holdco in this Article I and Annexes II and III shall be deemed, where applicable, to refer to such Subsidiary. For the avoidance of doubt, none of the Mixed Offer Consideration, the Stock Election Consideration or the Cash Election Consideration shall be reduced as a result of the payment by Euronext of the Special Euronext Distribution.

(b) Subject to Section 1.1(h), each Euronext Share accepted by Holdco pursuant to the Offer shall be exchanged for the right to receive from Holdco the Mixed Offer Consideration; provided that Holdco shall provide the Euronext shareholders with a "mix and match election" in the Offer so that each holder of Euronext Share may elect to receive in the Offer for each Euronext Share tendered by such holder in the Offer, in lieu of the Mixed Offer Consideration, either:

(i) a number of shares of Holdco Common Stock (the "Stock Election Amount") equal to the sum of (A) Standard Stock Amount and (B) the quotient obtained by dividing the Standard Cash Amount by the Pre-Offering Stock Price (such consideration, the "Stock Election Consideration" and persons who shall have tendered their Euronext Shares in this offer (offre d'échange subsidiaire) for the Stock Election Consideration are referred to as having made a "Stock Election"); or

(ii) an amount in cash (the "Cash Election Amount"), without interest, equal to the sum of (A) the Standard Cash Amount and (B) the product obtained by multiplying the Standard Stock Amount by the Pre-Offering Stock Price (such consideration, the "Cash Election Consideration" and persons who shall have tendered their Euronext Shares in this offer (offre d'achat subsidiaire) for the Cash Election Consideration are referred to as having made a "Cash Election").

(i) the "Cash Percentage" means the quotient obtained by dividing (x) the Standard Cash Amount by (y) the sum of (A) the Standard Cash Amount and (B) the product obtained by multiplying the Pre-Offering Stock Price by the Standard Stock Amount;

(ii) the "Stock Percentage" means the fraction obtained by subtracting the Cash Percentage from one;

A-2

(iii) the "Ratio" means the quotient obtained by dividing the Cash Percentage by the Stock Percentage;

(iv) the "Pre-Offering Stock Price" means the volume weighted average price of NYSE Group Common Stock on the New York Stock Exchange for the Pre-Offering Period, converted into euros using the average of the daily noon buying rates for euros, as published by the Federal Reserve Bank of New York, for the Pre-Offering Period; and

(v) the "Pre-Offering Period" means the ten (10) consecutive trading days ending on the day immediately prior to the filing of the Offer with the AMF pursuant to Section 1.1(a) or ending on such other date as mutually agreed between Euronext and NYSE Group.

(d) Notwithstanding Section 1.1(b), the number of Euronext Shares for which a Stock Election (the "Stock Election Shares") and the number of Euronext Shares for which a Cash Election shall be made (the "Cash Election Shares") shall be subject to an adjustment mechanism designed to ensure that, in the aggregate in the Offer, the quotient obtained by dividing the Cash Election Shares by the Stock Election Shares shall equal the Ratio. If the Cash Election Shares divided by the Stock Election Shares tendered in the Offer is not equal to the Ratio, then one of the following pro-ration and allocation adjustments shall occur:

(i) If the quotient obtained by dividing the Cash Election Shares by the Stock Election Shares exceeds the Ratio, then (A) each holder of a Stock Election Share shall receive in the Offer the Stock Election Consideration in respect of such Stock Election Share, and (B) the number of Cash Election Shares shall be reduced to the number required to achieve the Ratio (with such reduction to be pro rata among the holders of Euronext Shares who have made the Cash Election, based on the number of Euronext Shares for which they have made the Cash Election). The adjusted number of Cash Election Shares shall be rounded down to the nearest whole Cash Election Share. All Euronext Shares deemed not to be Cash Election Shares as a result of this pro-ration and allocation shall not be deemed to be Cash Election Shares or Stock Election Shares and shall receive the Mixed Offer Consideration.

(ii) If the quotient obtained by dividing the Cash Election Shares by the Stock Election Shares is less than the Ratio, then (A) each holder of a Cash Election Share shall receive in the Offer the Cash Election Consideration in respect of such Cash Election Share, and (B) the number of Stock Election Shares shall be reduced to the number required to achieve the Ratio (with such reduction to be pro rata among the holders of Euronext Shares who have made the Stock Election, based on the number of Euronext Shares for which they have made the Stock Election). The adjusted number of Stock Election Shares shall be rounded down to the nearest whole Stock Election Share. All Euronext Shares deemed not to be Stock Election Shares as a result of this pro-ration and allocation shall not be deemed to be Cash Election Shares or Stock Election Shares and shall receive the Mixed Offer Consideration.

(e) After the filing and commencement of the Offer as set forth in Section 1.1(a), Holdco's obligation to accept for exchange or payment, and to exchange or pay for, any Euronext Shares validly tendered and not withdrawn prior to the expiration of the Offer (as it may be extended in accordance with applicable Laws, the "Expiration Time") shall be subject only to the satisfaction or waiver of the conditions set forth in Annex III, including the condition that there shall be validly tendered in accordance with the terms of the Offer prior to the Expiration Time and not withdrawn, in each case in accordance with applicable Laws, a number of Euronext Shares that represents at least two-thirds of the outstanding Euronext Shares as of the closing of the Offer, as it may be extended by Holdco in accordance with applicable Laws (the "Minimum Condition"); provided, however, that, after consultation with Euronext, Holdco may change the Minimum Condition so that it is a number of Euronext Shares that represents not less than a majority of the Euronext Shares and not less than a majority of the Euronext voting power, in each case outstanding on a Fully Diluted Basis as of the closing of the Offer, as it may be extended by

A-3

Holdco in accordance with applicable Laws. As used in this Agreement, "Fully Diluted Basis" means, as of any particular time, the number of Euronext Shares issued and outstanding at such time after taking into account all Euronext Shares issuable upon the conversion of Euronext's convertible securities or upon the exercise of any options, warrants or rights to purchase or subscribe for shares of the capital stock of Euronext.

(f) Provided that this Agreement shall not have been earlier terminated in accordance with Article IX, and subject to the prior satisfaction or waiver of the conditions set forth in Annex III in accordance with the terms of Annex III, Holdco shall promptly consummate the Offer in accordance with its terms and applicable Law, and accept for exchange and payment, and exchange and pay for, all Euronext Shares tendered and not withdrawn in accordance with applicable Law, promptly following the acceptance of Euronext Shares for exchange and payment pursuant to the Offer. Holdco expressly reserves the right to increase the Standard Stock Amount and/or the Standard Cash Amount; provided that any such increase shall be reflected in the Offer Documents or any amendment thereof and filed with the SEC and the AMF, in each case as required by applicable Law.

(g) As promptly as practicable after the date of this Agreement, NYSE Group and Holdco shall prepare, and Holdco shall file with the U.S. Securities and Exchange Commission (the "SEC"), a registration statement on Form S-4 (together with any supplements or amendments thereto, the "Registration Statement") to register the offer and sale of Holdco Common Stock pursuant to the Offer and the Merger. The Registration Statement will include a proxy statement/prospectus (the "Proxy Statement/Prospectus") to be used for the NYSE Group Stockholders Meeting to approve and adopt this Agreement and the Merger (as well as the issuance of the shares of Holdco Common Stock in the Offer and the Merger) and to be used as a prospectus for the Offer; provided that, at its option, NYSE Group may file the proxy statement to be used for the NYSE Group Stockholders Meeting separately from the Registration Statement. In addition, as promptly as practicable after the date of this Agreement, NYSE Group and Holdco shall prepare, and Holdco shall file with the AMF a Share Registration Document (Document de Base) for the Offer in the form provided by Commission Regulation (EC) No. 809/2004 of April 2004 as implemented by the GRAMF (the "Holdco Share Registration Document"). As soon as practicable after the satisfaction or waiver of the conditions set forth in Annex II, (i) Holdco and Euronext shall jointly file with the AMF a Tender Offer Prospectus (Note d'Information) in accordance with the GRAMF and the related letter of transmittal form and other ancillary documents with respect to the Offer (together with all amendments, supplements and exhibits thereto and the Holdco Share Registration Document and any update of the Euronext Share Registration Document, the "French Exchange Offer Documents"), and (ii) Holdco shall file with the SEC a prospectus pursuant to Rule 424 under the U.S. Securities Act of 1933, as amended (the "Securities Act"), that will contain or incorporate by reference all or part of the Proxy Statement/Prospectus and the related letter of transmittal form and all other ancillary documents with respect to the Offer (together with all amendments, supplements and exhibits thereto, the "Prospectus") (the Prospectus, the Registration Statement and such documents included therein pursuant to which the Offer will be made, together with any amendments and supplements thereto, the "U.S. Exchange Offer Documents" and, together with the French Exchange Offer Documents, the "Offer Documents"). The parties hereto agree to take all steps necessary to cause the Registration Statement, the Share Registration Document, the French Exchange Offer Documents and the U.S. Exchange Offer Documents to be filed with the SEC and the AMF, as applicable, and disseminated to holders of NYSE Group Common Stock and Euronext Shares, as applicable, as and to the extent required by applicable Law. The parties agree to correct promptly any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect or as otherwise required by Law. The parties further agree to take all steps necessary to cause the Offer Documents, as so corrected, to be filed with the SEC and the AMF and disseminated to holders of NYSE Group Stock and Euronext Shares, as applicable, in each case as and to the extent required by applicable Law.

A-4

(h) Notwithstanding any other provision of this Agreement, no fractional shares of Holdco Common Stock will be issued to the Euronext Shareholders in the Offer. Any tendering holder who would be entitled to receive a fractional share of Holdco Common Stock but for this Section 1.1(h) shall instead receive a cash payment representing such holder's proportionate interest in the net proceeds from the sale on a regulated market for the account of the tendering shareholders of the aggregate fractional shares of Holdco Common Stock that the tendering holders otherwise would have received. Any such sale shall be made within ten (10) business days or such shorter period as may be required by applicable Law after the settlement of the Offer by an agent designated by Holdco. In no event will interest be paid on the cash to be received in lieu of any fraction of a share of Holdco Common Stock.

(i) NYSE Group and Euronext may agree to split the Offer into two or more separate exchange offers, including a separate U.S. offer and a non-U.S. offer. If the Offer shall be split into multiple exchange offers, each reference to the "Offer" set forth in this Agreement and the Annexes hereto shall refer to each of these separate offers unless the context otherwise requires.

(j) Except to the extent prohibited by applicable Law, Holdco shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the Mixed Offer Consideration, Stock Election Consideration and Cash Election Consideration payable to any tendering holder of Euronext Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or non-U.S. tax law. To the extent that amounts are so withheld by or on behalf of Holdco, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Euronext Shares in respect of which such deduction and withholding was made.

Section 1.2. Effect of the Offer on Euronext Stock Options. Unless NYSE Group and Euronext agree otherwise and subject to applicable Law, the Offer shall not include any outstanding option to purchase Euronext Shares, but, in accordance with the GRAMF, shall include any Euronext Share that is purchased or subscribed for as a result of the exercise of any such option prior to the Expiration Time.

(a) Each option to purchase shares of NYSE Group Common Stock (a "NYSE Group Stock Option") granted under the employee and director stock plans of NYSE Group (the "NYSE Group Stock Plans"), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall cease to represent a right to acquire shares of NYSE Group Common Stock and shall be converted, at the Effective Time, into a Holdco Stock Option on the same terms and conditions as were applicable under such NYSE Group Stock Option. The number of shares of Holdco Common Stock subject to each such Holdco Stock Option shall be equal to the number of shares of NYSE Group Common Stock subject to each such NYSE Group Stock Option and such Holdco Stock Option shall have an exercise price per share equal to the per share exercise price specified in such NYSE Group Stock Option.

(b) At the Effective Time, each restricted stock unit or deferred stock unit measured in shares of NYSE Group Common Stock (each, a "NYSE Group Stock-Based Award"), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall cease to represent a restricted stock unit or deferred stock unit with respect to shares of NYSE Group Common Stock and shall be converted, at the Effective Time, into a Holdco Stock-Based Award, on the same terms and conditions as were applicable under the NYSE Group Stock-Based Awards. The number of shares of Holdco Common Stock subject to each such Holdco Stock-Based Award shall be equal to the number of shares of NYSE Group Common Stock subject to the NYSE Group Stock-Based Award. All dividend equivalents credited to the account of each holder of a NYSE Group Stock-Based Award as of the Effective Time shall remain credited to such holder's account immediately following the Effective Time, subject to adjustment in accordance with the foregoing.

A-7

(c) As soon as practicable after the Effective Time, Holdco shall deliver to the holders of NYSE Group Stock Options and NYSE Group Stock-Based Awards appropriate notices setting forth such holders' rights pursuant to the respective NYSE Group Stock Plans and agreements evidencing the grants of such NYSE Group Stock Options and NYSE Group Stock-Based Awards and stating that such NYSE Group Stock Options and NYSE Group Stock-Based Awards and agreements have been assumed by Holdco and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 2.5 after giving effect to the Merger and the terms of the NYSE Group Stock Plans).

(d) Prior to the Effective Time, NYSE Group shall take all necessary action for the adjustment of NYSE Group Stock Options and NYSE Group Stock-Based Awards under this Section 2.5. Holdco shall reserve for issuance a number of shares of Holdco Common Stock at least equal to the number of shares of Holdco Common Stock that will be subject to Holdco Stock Options and Holdco Stock-Based Awards or the Equity Arrangements as a result of the actions contemplated by this Section 2.5 and Section 3.2. As soon as practicable following the Effective Time, Holdco shall file a registration statement on Form S-8 (or any successor form, or if Form S-8 is not available, other appropriate forms) with respect to the shares of Holdco Common Stock subject to such Holdco Stock Options and Holdco Stock-Based Awards and shall maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Holdco Stock Options and Holdco Stock-Based Awards remain outstanding.

Section 2.6. Delivery of Merger Consideration.

(a) Exchange Agent. Prior to the Effective Time, NYSE Group shall appoint a commercial bank or trust company, or a subsidiary thereof, to act as exchange agent hereunder (the "Exchange Agent"). On or prior to the Effective Time, (i) Holdco shall deposit, or cause to be deposited, with the Exchange Agent, for the benefit of holders of record of shares of NYSE Group Common Stock as of immediately prior to the Effective Time, shares of Holdco Common Stock issuable pursuant to Section 2.4 in exchange for outstanding shares of NYSE Group Common Stock upon delivery to the Exchange Agent of instructions for use in effecting the transfer and cancellation of Book-Entry Interests in exchange for the applicable Merger Consideration pursuant to the provisions of Article II (such shares of Holdco Common Stock being hereinafter referred to as the "Exchange Fund").

(b) Merger Transmittal Letter. NYSE Group and Holdco shall cause appropriate transmittal materials (the "Merger Transmittal Letter"), to be provided by the Exchange Agent to holders of record of shares of NYSE Group Common Stock as soon as practicable after the Effective Time advising such holders of the effectiveness of the Merger and the procedure for providing instructions to the Exchange Agent to effect the transfer and cancellation of Book-Entry Interests in exchange for the Merger Consideration.

(c) After the Effective Time, and upon delivery to the Exchange Agent of instructions authorizing transfer and cancellation of Book-Entry Interests in accordance with the terms of the Merger Transmittal Letter, the holder of such Book-Entry Interests shall be entitled to receive in exchange therefor a number of shares of Holdco Common Stock in respect of the aggregate Merger Consideration that such holder is entitled to receive pursuant to Section 2.4 (after taking into account all shares of NYSE Group Common Stock then held by such holder), and the Book-Entry Interests that are the subject of such authorization shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon such transfer and cancellation of any Book-Entry Interests. In the event of a transfer of ownership of NYSE Group Common Stock that is not registered in the transfer records of NYSE Group, the proper number of shares of Holdco Common Stock may be issued to such a transferee if written instructions authorizing the transfer of any Book-Entry Interests are presented to the Exchange Agent, in any case, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid. If any shares of Holdco Common Stock to be issued in a name other than that in which any Book-Entry Interests are registered, it shall be a condition of such exchange that the Person

A-8

requesting such exchange shall pay any transfer or other Taxes required by reason of the issuance of shares of Holdco Common Stock in a name other than that of the registered holder of any Book-Entry Interests, or shall establish to the satisfaction of Holdco or the Exchange Agent that such Tax has been paid or is not applicable. For the purposes of this Agreement, the term "Person" means any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization, Governmental Entity or Self-Regulatory Organization or other entity of any kind or nature. "Self-Regulatory Organization" means any U.S. or non-U.S. commission, board, agency or body that is not a Governmental Entity but is charged with the supervision or regulation of brokers, dealers, securities underwriting or trading, stock exchanges, commodities exchanges, electronic communication networks (ECNs), insurance companies or agents, investment companies or investment advisers.

(d) Distributions with Respect to Unexchanged Shares; Voting. All shares of Holdco Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by Holdco in respect of Holdco Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares issuable pursuant to this Agreement. No dividends or other distributions in respect of the Holdco Common Stock shall be paid to any holder of any Book-Entry Interests until the instructions for transfer and cancellation provided in this Article II have been delivered to the Exchange Agent. Subject to the effect of applicable Laws, following delivery to the Exchange Agent of such instructions with respect to Book-Entry Interests, there shall be issued to the holder of the shares of Holdco Common Stock issued in exchange therefor, without interest, (A) at the time of such surrender or delivery of such instructions, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such Holdco Common Stock and not paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such shares of Holdco Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender.

(e) Transfers. At or after the Effective Time, there shall be no transfers on the stock transfer books of NYSE Group of NYSE Group Common Stock that were outstanding immediately prior to the Effective Time.

(f) Fractional Shares. No fractional shares of Holdco Common Stock will be issued in the Merger to any holder of shares of NYSE Group Common Stock.

(g) Termination of Exchange Fund. Any portion of the Exchange Fund (including any Holdco Common Stock) that remains unclaimed by the former stockholders of NYSE Group for 180 days after the Effective Time shall be delivered to Holdco. Any former stockholders of NYSE Group who have not theretofore complied with this Article II shall thereafter look only to Holdco for delivery of any shares of Holdco Common Stock of such stockholders and payment of any dividends and other distributions in respect of Holdco Common Stock of such stockholders payable and/or issuable pursuant to this Article II upon delivery to the Exchange Agent of written instructions for the transfer and cancellation of any Book-Entry Interests, in each case, without any interest thereon. Notwithstanding the foregoing, none of Holdco, NYSE Group, Merger Sub, any surviving entity in the Merger, the Exchange Agent or any other Person shall be liable to any former holder of NYSE Group Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(h) Withholding Rights. Holdco shall be entitled to deduct and withhold, or to cause the Exchange Agent to deduct and withhold, from any consideration payable pursuant to the Merger to any Person who was a holder of NYSE Group Common Stock, NYSE Group Stock Option or NYSE Group Stock-Based Award immediately prior to the Effective Time such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or non-U.S. tax law. To the extent that amounts are so withheld

A-9

by Holdco or the Exchange Agent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the NYSE Group Common Stock, NYSE Group Stock Option or NYSE Group Stock-Based Award, as the case may be, in respect of which such deduction and withholding was made.

Section 2.7. Restructuring of the Merger. The parties hereto hereby agree and acknowledge that, with the prior consent of Euronext (which consent shall not be unreasonably withheld), NYSE Group may restructure the Merger; provided that such restructuring shall not (i) reduce or change the form of the Mixed Offer Consideration, the Stock Election Consideration or the Cash Election Consideration, (ii) materially delay or prevent consummation of the transactions contemplated by this Agreement, or (iii) prevent or materially impede the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code.

ARTICLE III

POST-CLOSING REORGANIZATION

Section 3.1. Post-Closing Reorganization.

(a) Holdco intends, simultaneously with or as soon as possible after the Closing, to effectuate a corporate reorganization (the "Post-Closing Reorganization") of Subsidiaries of Holdco (including Euronext and its Subsidiaries). The Post-Closing Reorganization may include any of the following (each of the following, a "Pre-Approved Post-Closing Reorganization"), each of which has been, to the extent required, approved by the Euronext Boards:

(i) if 95% or more of the outstanding Euronext Shares shall have been acquired in the Offer, Holdco may commence a compulsory acquisition by Holdco of Euronext Shares from any remaining minority shareholder in accordance with Section 2:92a of the Dutch Civil Code and/or an acquisition by Holdco of Euronext Shares from any remaining minority shareholder in accordance with Articles 236-1 et seq. of the GRAMF;

(ii) if less than 95% of the outstanding Euronext Shares shall have been acquired in the Offer:

(A) if the Euronext Shares have been acquired by Holdco, Holdco may transfer the Euronext Shares immediately following the consummation of the Offer to a newly formed, direct or indirect wholly owned Dutch Subsidiary of Holdco ("Dutch Holdco") in exchange for shares of Dutch Holdco; and

(B) Euronext may, and Holdco may cause Euronext to, transfer all of its assets and liabilities to a newly formed, wholly owned Dutch Subsidiary of Euronext ("Euronext Sub") in exchange for shares of Euronext Sub or by way of a legal demerger; and

(C) Euronext may, and Holdco may cause Euronext to, transfer the shares in Euronext Sub to Dutch Holdco in exchange for shares of Holdco Common Stock and cash and, then, cause Euronext to distribute such shares of Holdco Common Stock and cash to its shareholders in a complete liquidation of Euronext. To the extent that a liquidating distribution would be made to Dutch Holdco, Dutch Holdco may substitute a note for the portion of the consideration payable for the Euronext Sub shares that would be distributed to Dutch Holdco in the liquidation of Euronext; or

(D) Euronext may, and Holdco may cause Euronext to, merge with and into a newly formed, wholly owned Dutch Subsidiary of Dutch Holdco or Holdco ("Dutch Mergerco"), pursuant to which the Euronext shareholders will receive shares in Dutch Mergerco; after such merger, Holdco may cause Dutch Mergerco to transfer the shares in Euronext Sub to Dutch Holdco in exchange for shares of Holdco Common Stock and cash and, then, cause Dutch Mergerco to

A-10

distribute such shares of Holdco Common Stock and cash to the Dutch Mergerco shareholders in a complete liquidation of Dutch Mergerco. To the extent that a liquidating distribution would be made to Dutch Holdco, Dutch Holdco may substitute a note for the portion of the consideration payable for the Euronext Sub shares that would be distributed to Dutch Holdco in the liquidation of Dutch Mergerco;

provided that, if Holdco desires to take the actions specified in clause (D) above instead of clause (C) above, Holdco shall have received the written consent of Euronext prior to taking such actions (which consent shall not be unreasonably withheld unless the Euronext Boards, after consultation with outside counsel, determine in good faith that such consent would result in a breach of its fiduciary duties under applicable Law; it being understood that, in making this determination, the Euronext Boards shall consider the interests of all shareholders of Euronext to the extent that it considers the interests of any shareholder or group of shareholders of Euronext); provided, further that, in each case, the Post-Closing Reorganization shall be structured to provide holders of Euronext Shares who do not exchange such Euronext Shares in the Offer with the same number of shares of Holdco Common Stock and the same amount of cash (without taking into account the different tax treatment or withholding requirements that may apply) that such holders would have received in the Offer had such holder tendered its Euronext Shares in the Offer (and not made the Stock Election or the Cash Election).

(b) Holdco shall have the right to change the structure of the Post-Closing Reorganization, which changed structure may include, without limitation, (i) the amendment of the Articles of Association of Euronext to permit the creation, among other things, of separate classes of shares, (ii) the distribution of an extraordinary dividend on the shares of Euronext or a particular class or classes of shares of Euronext, (iii) the sale and transfer by Euronext, or any of its Subsidiaries, to Holdco or any affiliate or Subsidiary of Holdco, of all or a portion of the assets of Euronext or its Subsidiaries, (iv) the effectuation by Euronext and one or more Dutch Subsidiaries of Holdco of a legal merger within the meaning of Section 2:309 of the Dutch Civil Code, (v) the request for termination of the listing of the Euronext Shares on Euronext Paris, (vi) a liquidation of Euronext, (vii) the contribution of assets to Euronext in exchange for Euronext Shares (with the exclusion of preemptive rights, if any, of other shareholders, all in accordance with applicable Law) or (viii) any one or more combinations of any of the foregoing actions, all of which shall be conducted in accordance with applicable Law; provided, however, that Holdco shall not change the structure of the Post-Closing Reorganization without the prior written consent of Euronext (which consent shall not be withheld unless the Euronext Boards, after consultation with their outside legal counsel, determine in good faith that such consent would result in a breach of its directors' fiduciary duties under applicable Law; it being understood that, in making this determination, the Euronext Boards shall consider the interests of all shareholders of Euronext to the extent that it considers the interests of any shareholder or group of shareholders of Euronext) and shall have the right to propose alternatives for the Post-Closing Reorganization, which Holdco and NYSE Group shall consider in good faith. Holdco, NYSE Group and Euronext shall cooperate with each other in identifying and obtaining any Dutch tax clearances necessary or desirable in connection with the Post-Closing Reorganization.

(c) Subject to Sections 3.1(a) and 3.1(b), the Post-Closing Reorganization shall be structured so that, in the opinion of counsel to NYSE Group, the Post-Closing Reorganization, together with the Offer, constitutes either a "qualified stock purchase" within the meaning of Section 338 of the Code or a taxable asset purchase for U.S. federal income tax purposes, unless, at the election of NYSE Group, it is desirable to allow the Holdco Common Stock issued in the Offer and Post-Closing Reorganization to be received tax free by U.S. holders of Euronext Shares, in which case the Post-Closing Reorganization shall be structured so that, in the opinion of counsel to NYSE Group, the Post-Closing Reorganization, together with the Offer, constitutes either a reorganization (within the meaning of Section 368 of the Code) or part of a transfer of Euronext Shares described in Section 351 of the Code.

Section 3.2. Effect of Post-Closing Reorganization on Euronext Stock Options and Euronext Stock-Based Awards.

A-11

(a) Conversion. Except as provided in Section 3.2(b), at the Effective Time or to the extent not feasible at such date for some or all holders in some or all jurisdictions (for Tax reasons or otherwise), promptly thereafter and in any event no later than the completion of the Post-Closing Reorganization, each option to purchase Euronext Shares (a "Euronext Stock Option") and each restricted share, restricted stock unit or deferred stocks unit measured in Euronext Shares (each, a "Euronext Stock-Based Award") granted under the employee and director stock option and stock-based award plans of Euronext (the "Euronext Stock Plans"), whether vested or unvested, shall cease to represent a Euronext Stock Option or Euronext Stock-Based Award, respectively, and shall be converted into a stock option to acquire Holdco Common Stock (a "Holdco Stock Option") or a restricted share, restricted stock unit or deferred stock unit measured in Holdco Common Stock (a "Holdco Stock-Based Award"), respectively, on the same terms and conditions as were applicable under such Euronext Stock Option and Euronext Stock-Based Award prior to the Post-Closing Reorganization (or such other arrangement that the parties shall mutually agree prior to the filing of the Offer with the AMF); provided that the number of shares of Holdco Common Stock subject to each such Holdco Stock Option or Holdco Stock-Based Award shall be the number of Roussseau Shares subject to each such Euronext Stock Option or Euronext Stock-Based Award multiplied by the Stock Election Amount (assuming no pro-ration or adjustment as provided in Section 1.1(d)), rounded, if necessary, to the nearest whole share of Holdco Common Stock, and such Holdco Stock Option shall have an exercise price per share (rounded to the nearest one-hundredth of a cent) equal to the per share exercise price specified in such Euronext Stock Option divided by the Stock Election Amount (assuming no pro-ration or adjustment as provided in Section 1.1(d)).

(b) Specific Arrangement for Certain Holders. If it is reasonably foreseeable that the conversion of any of the Euronext Stock Options and/or Euronext Stock-Based Awards referred to in Section 3.2(a) would cause holders of Euronext Stock Options and/or Euronext Stock-Based Awards who are French residents for Tax purposes (the "French Holders") to incur additional Taxes or social security charges under French law (the "French Taxes"), as compared to the French Taxes that such French Holders would incur pursuant to the first sentence of Article 200 A 6 of the French General Tax Code with respect to Euronext Stock Options if such French Holders had converted the Euronext Stock Options after holding such Euronext Stock Options for four years from the date of grant of the original Euronext Stock Option or as compared to the French Taxes that such French Holders would incur pursuant to Article 200 A 6 bis of the French General Tax Code with respect to Euronext Stock-Based Awards if such French Holder had converted the Euronext Stock-Based Awards into Euronext Shares after holding such Euronext Stock-Based Awards for applicable vesting period and after holding the Euronext Common Stock resulting from such vesting for two years (the "Favorable Tax Amount" for such Euronext Stock Option or Euronext Stock-Based Award, as applicable), Holdco will offer to the French Holders of the Euronext Stock-Options and Euronext Stock-Based Awards, whether vested or unvested, the right to participate in certain equity arrangements entered into between Holdco and the relevant French Holders (the "Equity Arrangements"), pursuant to which Holdco shall undertake vis-à-vis each such French Holder, and each such French Holder shall undertake vis-à-vis Holdco, to exchange each Euronext Share purchased, subscribed or received pursuant to the Euronext Stock Options or Euronext Stock-Based Awards after the completion of the Offer for a number of shares of Holdco Common Stock equal to the Stock Election Amount (assuming no pro-ration or adjustment as provided in Section 1.1(d)); provided that nothing in this Section 3.2(b) shall limit or prohibit Holdco from undertaking the Post-Closing Reorganization in the time or manner that Holdco shall determine, subject to the requirements of Sections 3.1(a) and 3.1(b). In the event that Holdco shall undertake a Post-Closing Reorganization that (1) shall result in the termination of the Equity Arrangements, (2) shall prevent Euronext from issuing Euronext Shares upon exercise of the Euronext Stock Options or Euronext Stock-Based Awards or (3) shall cause the French Holders to incur French Taxes in an amount greater than the Favorable Tax Amount in respect of such Euronext Stock Options or Euronext Stock-Based Awards, then the outstanding Euronext Stock Options and Euronext Stock-Based Awards held by the French Holders shall be converted into Holdco Stock Options and Holdco Stock-Based Awards as provided in Section 3.2(a), and Holdco shall pay to each such French Holder (or pay to the

A-12

applicable Tax authority if required by applicable Law) an amount of cash (the "Gross-Up Payment") equal to the difference between (i) the aggregate amount of French Taxes imposed on such French Holder that arises as a result of the Post-Closing Reorganization, if any, minus (ii) the aggregate Favorable Tax Amount that such French Holders would have incurred with respect to such Euronext Stock Options and/or Euronext Stock-Based Awards after holding such Euronext Stock Options and/or Euronext Stock-Based Awards (or the resulting shares) for the period from the date of grant necessary to qualify for taxation based on the Favorable Tax Amount. In addition, Holdco shall pay to each such French Holder (or pay to the applicable Tax authority if required by applicable Law) an amount of cash equal to the aggregate French Taxes incurred by such French Holder as a result of the Gross-Up Payment and the payments pursuant to this sentence. Notwithstanding anything contained herein to the contrary, in no event shall Holdco be required to make any Gross-Up Payment or any other payment pursuant to this Section 3.2(b) in respect of (A) Euronext Stock Options originally granted under Euronext's SBF Option Plan or Euronext's 2002 Option Plan or any other Euronext Stock Options that were granted on a date that is four or more years prior to the date on which a conversion of such options occurs in accordance with Section 3.2(a) (including Holdco Stock Options upon any such conversion) or (B) a Euronext Stock-Based Award granted on a date that is granted prior to 2005, if any.

(c) Tax-Free Rollover. Subject to the provisions of Section 3.2(b), NYSE Group, Holdco and Euronext shall cooperate and use reasonable best efforts to cause, where possible, the conversion of all Euronext Stock Options and Euronext Stock-Based Awards into Holdco Stock Options or Holdco Stock-Based Awards (as applicable) as set forth in Section 3.2(a) not to be a taxable transaction for the holders of these Euronext Stock Options or Euronext Stock-Based Awards; provided that nothing in this Section 3.2(c) shall (A) limit or prohibit Holdco from undertaking the Post-Closing Reorganization in the time or manner that Holdco shall determine, subject to the requirements of Sections 3.1(a) and 3.1(b), or (B) subject to Section 3.2(b), require Holdco to compensate any holder of a Euronext Stock Option or Euronext Stock-Based Award for any Taxes or social security charges incurred or borne by such holder. Any adjustment to Euronext Stock Options or Stock-Based Awards shall comply with the requirements of Section 409A of the Code, to the extent applicable.

A-13

Section 3.3. Cooperation of Euronext. Euronext shall take, on or after the date of this Agreement, all actions reasonably necessary or desirable to accomplish the Post-Closing Reorganization (provided that the Post-Closing Reorganization shall not be required to be effective prior to the consummation of the Offer), including, without limitation: (i) the convening of the necessary meetings of Euronext shareholders and the Euronext Boards, (ii) the consideration of any and all necessary or desirable resolutions by the Euronext Boards for the purpose of the Post-Closing Reorganization, and (iii) the execution of any and all reasonably requested documents, agreements or deeds that are necessary or desirable to effectuate any of the corporate reorganizations and the filing or registration of any or all of such documents, agreements or deeds with the appropriate authorities or agencies. At the request of Holdco, Euronext shall, and shall cause its Subsidiaries to, except to the extent prohibited by applicable Law or contrary to the requirements of any European Regulator, (i) convert any Subsidiary of Euronext from an entity that is classified as a corporation pursuant to Treasury Regulation Section 301.7701-2(b)(8) into an entity that is an "eligible entity" (within the meaning of Treasury Regulation Section 301.7701-3(a)), (ii) make entity classification elections pursuant to Treasury Regulation Section 301.7701-3 for any Subsidiary of Euronext in such manner and with such effective dates as specified by Holdco, and (iii) subject to Sections 3.1(a) and 3.1(b), take any and all other reasonable actions that are required or desirable to accomplish the Post-Closing Reorganization.

Prior to any Change in Euronext Recommendation, Euronext shall provide NYSE Group written notice (the "Euronext Superior Proposal Notice") of Euronext's intention to make a Change in Euronext Recommendation at least four business days prior to making a Change in Euronext Recommendation, and shall consider any modifications to the terms of the transaction contemplated by this Agreement that are proposed by NYSE Group after its receipt of the Euronext Superior Proposal Notice (with respect to which modifications NYSE Group and Euronext shall negotiate in good faith during such four-business day period), in determining whether an Acquisition Proposal still constitutes a Superior Proposal for Euronext after such four-business day period.

(e) In the event that a third party who has previously made an Acquisition Proposal that the Board of Directors of NYSE Group or the Euronext Boards, as the case may be, has or have determined in accordance with this Section 7.2 is a Superior Proposal subsequently modifies or amends in an adverse manner any material term of such Superior Proposal, then such Board's prior determination shall be null and void and such Board shall be subject to the provisions of Section 7.2(c) and (d) in all respects (including the obligation to deliver a new NYSE Group Superior Proposal Notice or Euronext Superior Proposal Notice, as applicable, and negotiate in good faith with Euronext or NYSE Group, as applicable).

(f) Except as ordered by a court of competent jurisdiction or by shareholder action, each of NYSE Group and Euronext agrees that it will, and will cause its senior officers, directors and representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any parties conducted heretofore with respect to any Acquisition Proposal. Each of NYSE Group and Euronext agrees that it will use reasonable best efforts to promptly inform its directors, officers, agents and representatives of the obligations undertaken in this Section 7.2. Nothing in this Section 7.2 shall (x) permit Euronext or NYSE Group to terminate this Agreement (except as specifically provided in Article IX hereof) or (y) affect any other obligation of Euronext or NYSE Group under this Agreement, except as otherwise expressly set forth in this Agreement.

Section 7.3. Stockholders Meetings.

(a) NYSE Group will take, in accordance with applicable Law and the NYSE Group Organizational Documents, all action necessary to convene a meeting of its stockholders (the "NYSE Group Stockholders Meeting") on a date determined by NYSE Group after consultation with Euronext (the "NYSE Group Meeting Date"), which date shall be as promptly as practicable after the Registration Statement is declared

A-35

Such approval shall require a simple majority of the votes validly cast at such meeting (the "Euronext Requisite Vote"). Subject to fiduciary obligations under applicable Law, the Euronext Boards shall recommend such approval and shall take all lawful action to solicit such approval and shall recommend the Offer to its shareholders and recommend that they tender their Euronext Shares into the Offer. In the event that subsequent to the date hereof, the Euronext Boards determine that this Agreement is no longer advisable and either makes no recommendation or recommends that its shareholders not tender their Euronext Shares into the Offer (a "Change in Euronext Recommendation"), which Change in Euronext Recommendation shall be made only in accordance with Section 7.2(b), NYSE Group shall have a right to terminate this Agreement in accordance with Article IX.

Subject to Sections 7.2 and 9.6, whether or not the Offer or the Merger is consummated, all Expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such Expenses, except Expenses incurred in connection with (i) the filing, printing and mailing of the Euronext Shareholder Circular, the Proxy Statement/Prospectus, the Registration Statement and the Offer Documents, (ii) any required filing with any Governmental Authority or Self-Regulatory Organization in connection with the transactions contemplated by this Agreement, and (iii) any commitment fees or other expenses in connection with obtaining financing to pay all or part of the cash portion of the consideration payable in the Offer, in each of cases (i), (ii) and (iii), which Expenses shall be shared equally by NYSE Group and Euronext unless prohibited by applicable Law. As used in this Agreement, "Expenses" includes all out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, experts and consultants to a party hereto and its affiliates) incurred by a party or on its behalf in connection with or related to the authorization, preparation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby, including the preparation, printing, filing and mailing of the Offer Documents and the solicitation of stockholder approvals and all other matters related to the transactions contemplated hereby and thereby.

Section 7.11. Indemnification; Directors' and Officers' Insurance.

(a) From and after the Effective Time, Holdco shall (i) indemnify and hold harmless, and provide advancement of expenses to, all past and present directors, officers and employees of NYSE Group and its Subsidiaries (in all of their capacities) (A) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by NYSE Group pursuant to the NYSE Group Organizational Documents and indemnification agreements, if any, in existence on the date hereof with any directors, officers and employees of NYSE Group and its Subsidiaries and (B) without limitation to clause (A), to the fullest extent permitted by law, in each case for acts or omissions occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby), (ii) include and cause to be

A-40

maintained in effect in Holdco's (or any successor's) certificate of incorporation and bylaws after the Effective Time, provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses which are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions contained in the current certificate of incorporation and constitution of NYSE Group and (iii) cause to be maintained for a period of six years after the Effective Time the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by NYSE Group (provided that Holdco (or any successor) may substitute therefor one or more policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured) with respect to claims arising from facts or events that occurred on or before the Effective Time; provided, however, that in no event shall Holdco be required to expend in any one year an amount in excess of 250% of the annual premiums (such 250% amount, the "Maximum NYSE Group Insurance Amount") currently paid by NYSE Group for such insurance; and, provided, further, that if the annual premiums of such insurance coverage exceed such amount, Holdco shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount. Holdco may, in lieu of maintaining the insurance described in clause (iii) of Section 7.11(a), purchase a six-year "tail" prepaid policy on terms and conditions no less advantageous to the insured than the current directors' and officers' liability insurance and fiduciary liability insurance maintained by NYSE Group; provided that the amount paid by Holdco shall not exceed six times the Maximum NYSE Group Insurance Amount. The obligations of Holdco under this Section 7.11(a) shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 7.11(a) applies without the consent of such affected indemnitee (it being expressly agreed that the indemnities to whom this Section 7.11(a) applies shall be third party beneficiaries of this Section 7.11(a)).

(b) From and after the Effective Time, Holdco shall (i) indemnify and hold harmless, and provide advancement of expenses to, all past and present directors, officers and employees of Euronext and its Subsidiaries (in all of their capacities) (A) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by Euronext pursuant to the Euronext Organizational Documents and indemnification agreements, if any, in existence on the date hereof with any directors, officers and employees of Euronext and its Subsidiaries and (B) without limitation to clause (A), to the fullest extent permitted by law, in each case for acts or omissions occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby), (ii) include and cause to be maintained in effect in Holdco's (or any successor's) certificate of incorporation and bylaws after the Effective Time, provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses which are, in the aggregate, no less advantageous to the intended beneficiaries than the corresponding provisions contained in the current certificate of incorporation and bylaws of Euronext and (iii) cause to be maintained for a period of six years after the Effective Time the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by Euronext (provided that Holdco (or any successor) may substitute therefor one or more policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured) with respect to claims arising from facts or events that occurred on or before the Effective Time; provided, however, that in no event shall Holdco be required to expend in any one year an amount in excess of 250% of the annual premiums (such 250% amount, the "Maximum Euronext Insurance Amount") currently paid by Euronext for such insurance (which annual premiums are set forth in Section 7.11(b) of the Euronext Disclosure Letter); and, provided, further, that if the annual premiums of such insurance coverage exceed such amount, Holdco shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount. Holdco may, in lieu of maintaining the insurance described in clause (iii) of Section 7.11(b), purchase a six-year "tail" prepaid policy on terms and conditions no less advantageous to the insured than the current directors' and officers' liability insurance and fiduciary liability insurance maintained by Euronext; provided that the amount paid by Holdco shall not exceed six times the Maximum Euronext Insurance Amount. The obligations of

A-41

Holdco under this Section 7.11(b) shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 7.11(b) applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 7.11(b) applies shall be third party beneficiaries of this Section 7.11(b)).

Section 7.12. Other Actions by NYSE Group and Euronext.

(a) Section 16 Matters. Prior to the Effective Time, NYSE Group and Euronext shall take all such steps as may be required to cause any dispositions of NYSE Group Common Stock and Euronext Shares (including derivative securities with respect to NYSE Group Common Stock or Euronext Shares) or acquisitions of Holdco Common Stock (including derivative securities with respect to Holdco Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to NYSE Group and Euronext, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

(b) Advice of Changes. Until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms, (i) NYSE Group shall promptly advise Euronext of any change or event that it believes would or would reasonably be likely to cause or constitute a Material Adverse Effect on NYSE Group; and (ii) Euronext shall promptly advise NYSE Group of any change or event that it believes would or would reasonably be likely to cause or constitute a Material Adverse Effect on Euronext; provided that failure to so promptly advise shall not constitute a material breach or failure of a condition unless the underlying change or event shall constitute such material breach or failure.

(a) THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN, AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF, THE STATE OF DELAWARE WITHOUT REGARD TO THE CONFLICT OF LAW PRINCIPLES THEREOF.

(b) The parties hereby (i) irrevocably submit to the exclusive jurisdiction of the courts of the State of Delaware (the "Delaware Courts") and the Federal Courts of the United States of America located in the

A-45

State of Delaware (the "Federal Courts") in respect of any claim, dispute or controversy relating to or arising out of the negotiation, interpretation or enforcement of this Agreement or any of the documents referred to in this Agreement or the transactions contemplated hereby or thereby (any such claim being a "Covered Claim"); (ii) irrevocably agree to request that the Delaware or Federal Courts adjudicate any Covered Claim on an expedited basis and to cooperate with each other to assure that an expedited resolution of any such dispute is achieved; (iii) waive, and agree not to assert, as a defense in any action, suit or proceeding raising a Covered Claim that any of the parties hereto is not subject to the personal jurisdiction of the Delaware or Federal Courts or that such action, suit or proceeding may not be brought or is not maintainable in said Courts or that the venue thereof may be inappropriate or inconvenient or that this Agreement or any such document may not be enforced in or by such Courts; and (iv) irrevocably agree to abide by the rules of procedure applied by the Delaware or Federal Court (as the case the may be) (including but not limited to procedures for expedited pre-trial discovery) and waive any objection to any such procedure on the ground that such procedure would not be permitted in the courts of some other jurisdiction or would be contrary to the laws of some other jurisdiction. The parties further agree that any Covered Claim has a significant connection with the State of Delaware and with the United States, and will not contend otherwise in any proceeding in any court of any other jurisdiction. Each party represents that it has agreed to the jurisdiction of the Delaware and Federal Courts in respect of Covered Claims after being fully and adequately advised by legal counsel of its own choice concerning the procedures and law applied in the Delaware and Federal Courts and has not relied on any representation by any other party or its Affiliates, representatives or advisors as to the content, scope, or effect of such procedures and law, and will not contend otherwise in any proceeding in any court of any jurisdiction. Notwithstanding the foregoing, nothing in this Agreement shall limit the right of NYSE Group, Holdco or any of their respective Subsidiaries or affiliates to commence or prosecute any legal action against Euronext or any of its Subsidiaries or affiliates in any court of competent jurisdiction in France, The Netherlands, or elsewhere to enforce the judgments and orders of the Delaware or Federal Courts.

(c) Each party hereby irrevocably agrees that it will not oppose, on any ground, the recognition, enforcement, or exequatur in a French, Dutch or other court of any judgment (including but not limited to a judgment requiring specific performance) rendered by a Delaware or Federal Court in respect of a Covered Claim.

(d) Euronext hereby irrevocably designates Liffe USA Limited (in such capacity the "Process Agent"), with an office at 55 Broadway, Suite 2602, New York, New York 10006, as its designee, appointee and agent to receive, for and on its behalf service of process in such jurisdiction in any legal action or proceedings with respect to this Agreement or any other agreement executed in connection with this Agreement, and such service shall be deemed complete upon delivery thereof to the Process Agent; provided that, in the case of any such service upon the Process Agent, the party effecting such service shall also deliver a copy thereof to Euronext. Euronext shall take all such action as may be necessary to continue said appointment in full force and effect or to appoint another agent so that Euronext will at all times have an agent for service of process for the above purposes in New York, New York. In the event of the transfer of all or substantially all of the assets and business of the Process Agent to any other person or entity by consolidation, merger, sale of assets or otherwise, such other person or entity shall be substituted hereunder for the Process Agent with the same effect as if named herein in place of such Process Agent. Euronext further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered airmail, postage prepaid, to such party at its address set forth in this Agreement, such service of process to be effective upon acknowledgment of receipt of such registered mail. Nothing herein shall affect the right of any party to serve process in any other manner permitted by applicable law. Euronext expressly acknowledges that the foregoing waiver is intended to be irrevocable under the laws of the State of Delaware and of the United States of America.

The Board of Directors
NYSE Group, Inc.
11 Wall Street
New York, New York 10005

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of view, to NYSE Group, Inc., a Delaware corporation ("NYSE Group"), of the Aggregate Consideration (defined below) to be paid by NYSE Euronext, Inc., a Delaware corporation and a newly formed, wholly owned subsidiary of NYSE Group ("Holdco"), pursuant to the terms and subject to the conditions of the Combination Agreement, dated as of June 2, 2006 (the "Combination Agreement"), by and among NYSE Group, Euronext N.V., a company organized under the laws of The Netherlands ("Euronext"), Holdco and Jefferson Merger Sub, Inc., a Delaware corporation and a newly formed, wholly owned subsidiary of Holdco ("Merger Sub"). As more fully described in the Combination Agreement, (i) Holdco (or a wholly owned subsidiary of Holdco) will commence an exchange offer (the "Offer") to acquire all of the issued and outstanding shares, nominal value €1 per share, of Euronext ("Euronext Shares"), each in exchange for 0.98 of a share of common stock, par value $0.01 per share, of Holdco ("Holdco Common Stock") and €21.32 in cash (the "Offer Consideration"), and (ii) concurrently with the purchase by Holdco (or a wholly owned subsidiary of Holdco) of the Euronext Shares pursuant to the Offer, Merger Sub will merge with and into NYSE Group, with NYSE Group surviving the merger as a wholly owned subsidiary of Holdco (the "Merger" and, together with the Offer, the "Transactions"), and in the Merger, each outstanding share of the common stock, par value $0.01 per share, of NYSE Group ("NYSE Group Common Stock") will be converted into the right to receive one share of Holdco Common Stock. Pursuant to the Combination Agreement, in lieu of the Offer Consideration, each holder of Euronext Shares may elect to receive in the Offer for each Euronext Share tendered by such holder in the Offer either the Cash Election Consideration or the Stock Election Consideration (each as defined in the Combination Agreement) (the aggregate consideration to be received by the holders of Euronext Shares in the Offer, the "Aggregate Consideration"), in each case subject to certain election procedures and adjustments to ensure that the aggregate amount of cash and shares of Holdco Common Stock to be paid pursuant to the Offer will equal the number of Euronext Shares validly tendered and not withdrawn in the Offer multiplied by the Offer Consideration (except to the extent that any cash is paid in lieu of the issuance of fractional shares of Holdco Common Stock).

In arriving at our opinion, we reviewed the Combination Agreement and held discussions with certain senior officers, directors and other representatives and advisors of NYSE Group and certain senior officers and other representatives and advisors of Euronext concerning the business, operations and prospects of NYSE Group and Euronext. We examined certain publicly available business and financial information relating to NYSE Group and Euronext as well as certain financial forecasts and other information and data relating to NYSE Group and Euronext which were provided to or otherwise reviewed by or discussed with us by the respective managements of each of NYSE Group and Euronext, including information relating to the potential strategic implications and operational benefits (including the amount, timing and achievability thereof) anticipated by the management of each of NYSE Group and Euronext to result from the Transactions, and adjustments to the forecasts and other information and data relating to Euronext discussed with us by the management of NYSE Group. In addition, we have assumed with your consent, that there are no material undisclosed liabilities of NYSE Group and Euronext for which adequate reserves or other provisions have not been made. We reviewed the financial terms of the Transactions as set forth in the Combination Agreement in relation to, among other things: current and historical market prices and trading volumes of NYSE Group Common Stock and Euronext Shares; the historical and projected earnings and other operating data of each of NYSE Group and Euronext; and the capitalization and financial condition of each of NYSE Group and Euronext. We considered, to the extent publicly available, the financial terms of certain other transactions which we considered relevant in evaluating the Transactions and analyzed certain financial, stock market and other publicly available information relating to the businesses of other companies whose operations we considered relevant in evaluating those of

NYSE Group and Euronext. We also evaluated certain potential pro forma financial effects of the Transactions on NYSE Group. In addition to the foregoing, we conducted such other analyses and examinations and considered such other information and financial, economic and market criteria as we deemed appropriate in arriving at our opinion.

In rendering our opinion, we have assumed and relied, without assuming any responsibility for independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and upon the assurances of the managements of NYSE Group and Euronext that they are not aware of any relevant information that has been omitted or that remains undisclosed to us. With respect to financial forecasts and other information and data provided to or otherwise reviewed by or discussed with us relating to NYSE Group and Euronext, including certain potential pro forma financial effects of, and strategic implications and operational benefits anticipated to result from, the Transactions, we have been advised by the respective managements of NYSE Group and Euronext that such forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of NYSE Group and Euronext as to the future financial performance of NYSE Group and Euronext. We have assumed, with your consent, that the financial results (including the potential pro forma financial effects, strategic implications and operational benefits anticipated to result from the Transactions) reflected in such forecasts and other information and data will be realized in the amounts and at the times projected by NYSE Group management. We have assumed, with your consent, that the Transactions will be consummated in accordance with their terms, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Transactions, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on NYSE Group, Euronext or the contemplated benefits of the Transactions. We have also assumed, with your consent, that Holdco was organized in connection with the Transactions, and upon consummation of the Transactions, its sole assets will be the Euronext Shares acquired pursuant to the Offer and all of the shares of NYSE Group Common Stock. We also have assumed, with your consent, that the Merger will be treated as a tax-free reorganization for U.S. federal income tax purposes. We are not expressing any opinion as to what the value of the Holdco Common Stock actually will be when issued pursuant to the Transactions or the price at which the Holdco Common Stock will trade at any time. We have not made or been provided with an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of NYSE Group or Euronext nor have we made any physical inspection of the properties or assets of NYSE Group or Euronext. We express no view as to, and our opinion does not address, the relative merits of the Transactions as compared to any alternative business strategies that might exist for NYSE Group or the effect of any other transaction in which NYSE Group might engage. Our opinion does not address or take into account any Post-closing Reorganization (as defined in the Combination Agreement) that may occur following the closing of the Offer, or the consideration that may be paid pursuant to such Post-Closing Reorganization. Our analysis assumes that 100% of the Euronext Shares are acquired by Holdco for the Offer Consideration. Our opinion is necessarily based upon information available to us, and financial, stock market and other conditions and circumstances existing, as of the date hereof.

Citigroup Global Markets Inc. ("Citigroup") has acted as financial advisor to NYSE Group in connection with the proposed Transactions and will act as dealer manager for the Offer and will receive a fee for such services, a significant portion of which is contingent upon the consummation of the Transactions. We also will receive a fee in connection with the delivery of this opinion and upon the closing of the Offer. We and our affiliates in the past have provided services to NYSE Group unrelated to the proposed Transactions, for which services we and such affiliates have received compensation, including, without limitation, acting as financial advisor, and providing a fairness opinion in 2005, to the New York Stock Exchange, Inc., a predecessor to NYSE Group (the "NYSE, Inc."), in connection with its merger with Archipelago Holdings, Inc. ("Archipelago") and acting as co-manager with respect to the offering of

B-2

28,750,000 shares of NYSE Group Common Stock by stockholders of NYSE Group in May 2006. We also bring your attention to the following relationships:

Shares of Citigroup Inc., the parent company of Citigroup, are listed on the New York Stock Exchange LLC ("NYSE") and, accordingly, Citigroup Inc. pays listing fees to the NYSE. In addition, certain current and former officers of Citigroup and its affiliates have in the past served on the board of directors of the NYSE, Inc. and certain employees of Citigroup and its affiliates serve on various NYSE committees.

Citigroup and its affiliates are collectively a leading trader of NYSE stocks and maintain a trading operation on the NYSE floor.

John Reed, Citigroup Inc.'s former Chairman and Co-Chief Executive Officer, is a former Chairman and Chief Executive Officer of the NYSE, Inc. In addition, Richard Ketchum, former General Counsel of Citigroup, is the Chief Executive Officer of NYSE Regulation, Inc.

Citigroup and its affiliates have provided financial advisory services to, and conduct securities trading through the trading systems of, Archipelago and its affiliates, including NYSE Arca, Inc. ("NYSE Arca"), and received fees in connection therewith, including advising NYSE Arca Holdings, Inc. (then known as PCX Holdings, Inc.), the parent of NYSE Arca, in its sale to Archipelago Holdings, Inc. In addition, Citigroup holds Equity Trading Permits and Options Trading Permits issued by NYSE Arca and, accordingly, is subject to its regulatory oversight. Certain current and former employees of Citigroup and its affiliates have in the past served and are currently serving on the NYSE Arca board of directors.

Citigroup is a NYSE Member Organization and, accordingly, is subject to the regulatory oversight of the NYSE.

Citigroup Global Markets Limited, an affiliate of Citigroup ("CGML"), is a member of, and conducts securities trading through the exchanges of, certain of Euronext's affiliates, including Euronext Amsterdam, Euronext Paris, Euronext.liffe and MTS European Bond Trading, and accordingly, is subject to the regulatory oversight of such exchanges. CGML also holds equity positions in certain of these exchanges in connection with its membership in such exchanges.

In the ordinary course of our business, we and our affiliates may actively trade or hold the securities of NYSE Group and Euronext for our own account or for the account of our customers and, accordingly, may at any time hold a long or short position in such securities. We currently hold for our own account approximately 637,576 shares of NYSE Group Common Stock and approximately 191,000 Euronext Shares, representing approximately 0.4% and 0.17% of the outstanding shares of NYSE Group and Euronext, respectively. In addition, we and our affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with Euronext and its affiliates and companies in which they may have an investment.

Our advisory services and the opinion expressed herein are provided solely for the information of the Board of Directors of NYSE Group in its evaluation of the proposed Transactions, and our opinion is not intended to be and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act on any matters relating to the proposed Transactions.

Based upon and subject to the foregoing, our experience as investment bankers, our work as described above and other factors we deemed relevant, we are of the opinion that, as of the date hereof, the Aggregate Consideration to be paid by Holdco in the Offer is fair, from a financial point of view, to NYSE Group.

Very truly yours,

CITIGROUP GLOBAL MARKETS INC.

[LETTERHEAD OF MORGAN STANLEY & CO. LIMITED]

1 June 2006

PRIVATE AND CONFIDENTIAL

Euronext N.V.
The Supervisory Board
The Management Board
Beursplein 5
1000 GD Amsterdam
The Netherlands

Gentlemen:

We understand that Euronext N.V. ("Euronext") and New York Stock Exchange Group, Inc. ("NYSE") propose to enter into an agreed transaction whereby Euronext shall combine with NYSE (the "Transaction"). We understand that pursuant to the Transaction, (i) a newly formed company ("Holdco") will establish a subsidiary that will merge into NYSE with each share of NYSE common stock converting into the right to receive one share of Holdco common stock, and (ii) Holdco will make a mix-and-match exchange offer (the "Offer") for all outstanding Euronext shares pursuant to which tendering Euronext shareholders will receive, in exchange for each outstanding Euronext common share, €21.32 in cash and 0.98 shares of common stock of Holdco (subject to their right to make elections to receive, subject to proration, all cash or all stock) upon the terms as described in the Combination Agreement draft dated 31 May 2006 (the "Agreement").

You have asked for our opinion as to whether the consideration to be received by the holders of common shares of Euronext in the Offer is fair from a financial point of view to such holders.

For purposes of the opinion set forth herein, we have:

i): reviewed certain publicly available financial statements and other information of Euronext and NYSE;
ii): reviewed certain internal financial statements and other financial and operating data concerning Euronext prepared by the management of Euronext;
iii): reviewed certain financial projections prepared by the management of Euronext and discussed the past and current operations and financial condition and the prospects of Euronext with senior executives of Euronext;
iv): reviewed certain financial projections prepared by the management of NYSE and discussed the past and current operations and financial condition and the prospects of NYSE with senior executives of NYSE;
v): reviewed the reported prices and trading activity for the common shares of Euronext and the common stock of NYSE;
vi): compared the financial performance of each of Euronext and NYSE and the prices and trading activity of Euronext common shares and the NYSE common stock with that of certain other comparable publicly-traded companies and their securities;
vii): reviewed the financial terms, to the extent publicly available, of certain comparable transactions;
viii): discussed with Euronext and NYSE management their assessment of the benefits which they believe can be realized from this transaction;

ix): participated in discussions and negotiations among representatives of Euronext and NYSE and their financial and legal advisers;
x): reviewed a draft of the Agreement dated 31 May 2006; and
xi): reviewed such other information, performed such other analyses, and considered such other factors as we have deemed appropriate.

We have assumed and relied upon without independent verification the accuracy and completeness of the information reviewed by us for the purposes of this opinion. With respect to the financial projections, including in relation to strategic, financial, and operational benefits expected to be realized from the transaction, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of each of Euronext and of NYSE. We are not legal, tax or regulatory advisors, we are financial advisors only. We have not made any independent valuation or appraisal of the assets or liabilities of Euronext or of NYSE, nor have we been furnished with any such appraisals. In addition, we have assumed that the transaction will be consummated in accordance with the terms set forth in the agreement, and that in connection with the receipt of all necessary anti-trust and regulatory approvals for the transaction, no restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived from the transaction. Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof, may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

We have acted as financial advisor to the Supervisory and Management Boards of Euronext in connection with the Transaction and will receive a fee for our services, a substantial part of which is conditioned upon consummation of the Transaction. In the past, Morgan Stanley & Co. Limited and its affiliates have provided financial advisory and financing services for Euronext and NYSE, and have received fees for the rendering of these services. We may also seek to provide such services to Euronext, NYSE and Holdco in the future and will receive fees for the rendering of these services. In the ordinary course of our trading, brokerage, investment management and financing activities, Morgan Stanley or its affiliates may at any time hold long or short positions, and may trade or otherwise effect transactions, for our own account or the accounts of customers, in debt or equity securities or senior loans of Euronext or NYSE or any other company or any currency or commodity that may be involved in this transaction.

It is understood that this letter is for the information of the Supervisory and Management Boards of Euronext and may not be used for any other purpose without our prior written consent. It is not addressed to and may not be relied upon by any third party other than Euronext. Except as required by applicable law or regulation, this opinion may not be referred to, communicated or disclosed without our prior written consent. This opinion expresses no opinion or recommendation as to how Euronext shareholders should vote at any shareholders' meeting to be held in connection with the Transaction nor as to whether they should accept the Offer. In addition, this opinion does not in any manner address the prices at which Holdco's shares will trade following consummation of the Transaction.

Based on and subject to the foregoing, we are of the opinion on the date hereof that the consideration to be received by the holders of common shares of Euronext in the Offer is fair from a financial point of view to such holders, as a whole.

Very truly yours,

The Managing Board and Supervisory Board
Euronext N.V.

France

Strictly Private and Confidential

Letter of opinion

1 June 2006

Dear Sirs,

We understand that NYSE Euronext Inc, a company established under the laws of Delaware ("NYSE Euronext" or the "Offeror"), is proposing (i) to make a public offer, directly or through a wholly-owned subsidiary, to acquire all the issued and outstanding shares with a nominal value of Euro 1.00 per share (each a "Share" and each beneficial owner of a Share a "Shareholder") in the capital of Euronext N.V., a company established under the laws of The Netherlands ("Euronext" or the "Company")(the "Offer"), and (ii) concurrently with the consummation of the Offer, to cause its wholly-owned subsidiary currently referred to as Merger Sub Inc, a company established under the laws of Delaware ("Merger Sub") to merge with NYSE Group Inc, a company established under the laws of Delaware ("NYSE Group"), with NYSE Group surviving the merger as a wholly owned subsidiary of NYSE Euronext (the "Merger").

Pursuant to the terms of the Offer as set out in a combination agreement, substantially in the form of the draft dated 1 June, 2006 (the "Combination Agreement"), each Shareholder will be offered the right to exchange one Share for (i) 0.980 shares of common stock, par value USD 0.01 per share of NYSE Euronext (each a "NYSE Euronext Share" or "Offeror Share") and (ii) Euro 21.32 in cash (together the "Offer Consideration"). The Offer Consideration would imply an exchange ratio of c. 1.44 NYSE Euronext Shares for each Share, with c. 32.5 per cent. of the aggregate consideration paid in cash based on the closing share prices of the Shares and of the shares of common stock, par value USD 0.01 per share, of NYSE Group (the "NYSE Group Shares") on 31 May 2006. We understand that according to the terms of the Combination Agreement, Shareholders may instead elect to receive the Offer Consideration in cash or in Offeror Shares only, subject inter alia to the adjustment mechanisms as detailed in the Combination Agreement.

We furthermore understand that the transaction terms also assume that Euronext will pay to its Shareholders a previously announced extraordinary dividend of Euro 3.00 per Share (or a reduction of capital of the Company if such reduction shall not delay the commencement of the Offer).

Pursuant to our engagement letter dated 1 June, 2006, the managing board ("Managing Board") and supervisory board ("Supervisory Board") of the Company have asked for the opinion of ABN AMRO Corporate Finance France S.A. ("ABN AMRO") as to whether the Offer Consideration is fair, from a financial point of view, to the Shareholders.

For the purposes of providing our opinion, ABN AMRO has:

1.: Reviewed certain publicly available business and financial information relating to Euronext, including Euronext's audited consolidated financial statements for the three consecutive financial years ending 31 December 2005, 2004 and 2003 and the unaudited quarterly figures for the period ending 31 March 2006, and certain publicly available financial forecasts relating to the business and financial prospects of Euronext prepared by certain research analysts;

2.: Reviewed certain publicly available business and financial information relating to NYSE Group, including NYSE Group's unaudited pro forma condensed combined financial data for the financial year ending 31 December 2005 (Form S-1 dated 13 April 2006, as amended through 4 May 2006) and the unaudited quarterly figures for the period ending 31 March 2006 and certain publicly available financial forecasts relating to the business and financial prospects of NYSE Group prepared by certain research analysts;
3.: Reviewed NYSE Group's specific regulatory filings with regard to its merger with Archipelago (Joint Proxy Statement / Prospectus on Form S-3, dated 3 November 2005, as further supplemented and amended pursuant to the Supplement dated 23 November 2005) and secondary offering (Form S-1 dated 13 April 2006, as amended through 4 May 2006) and the business plan of the NYSE Group which has been provided to us by NYSE Group's advisers;
4.: Participated in discussions with and reviewed information provided by the senior management of Euronext and NYSE Group with respect to the businesses and prospects of Euronext and NYSE Group;
5.: Participated in discussions with, and reviewed information provided by, relevant employees of Euronext and NYSE Group with regard to the expected synergies which a combination of Euronext and NYSE Group is expected to generate;
6.: Reviewed the historical stock prices and trading volumes of the Shares and the NYSE Group Shares;
7.: Reviewed the financial terms of certain transactions we believe to be comparable to the Offer;
8.: Reviewed public information with respect to certain other companies we believe to be comparable to Euronext and NYSE Group;
9.: Reviewed those parts of the Combination Agreement and other documents, that we deemed relevant for the purposes of providing this opinion; and
10.: Performed such other financial reviews and analysis, as we, in our absolute discretion, have deemed appropriate.

With respect to any financial forecasts (including forecasts regarding the estimated amount and timing of certain revenue, cost and tax synergies projected to result from the combination of Euronext and NYSE Group) that may have been made available, ABN AMRO has assumed that they have been reasonably prepared on bases reflecting the best available estimates and judgements of the management of Euronext and NYSE Group as to the future financial performance of Euronext and/or NYSE Group and/or NYSE Euronext, and that no event subsequent to the date of any such financial forecasts has had a material effect on them. In addition we have extended certain of those forecasts into future periods based on various assumptions. ABN AMRO does not assume or accept liability or responsibility for (and expresses no view as to) any such forecasts or the assumptions on which they are based. ABN AMRO has assumed and relied upon, without independent verification, the truth, accuracy and completeness of the information, forecasts (that may have been made available), data and financial terms provided to us or used by us, has assumed that the same are not misleading and does not assume or accept any liability or responsibility for any independent verification of such information or any independent valuation or appraisal of any of the assets, operations or liabilities of Euronext or NYSE Group nor have we been provided with any such valuation or appraisal. In preparing this opinion, ABN AMRO has received specific confirmation from senior management of Euronext that the assumptions specified above are reasonable and no information has been withheld from ABN AMRO that could have influenced the purport of this opinion or the assumptions on which it is based. ABN AMRO did not seek nor obtain such confirmation from NYSE Group.

D-2

Further, ABN AMRO's opinion is necessarily based on financial, economic, monetary, exchange rate, market and other conditions, as in effect on, and the information made available to ABN AMRO or used by it up to, the date hereof. This opinion exclusively focuses on the fairness, from a financial point of view, of the Offer Consideration to the Shareholders and does not address any other issues such as the underlying business decision to agree to a business combination between Euronext and NYSE Group or to recommend the Offer, or the commercial merits of the foregoing, which are matters solely for the Supervisory Board and the Managing Board of Euronext. In addition, this opinion does not in any manner address the prices or volumes at which the Shares, the Offeror Shares, the NYSE Group Shares or the shares of any other entities involved in the transactions contemplated by the Combination Agreement, may trade following consummation of the Offer. Subsequent developments in the aforementioned conditions may affect this opinion and the assumptions made in preparing this opinion and ABN AMRO is not obliged to update, revise or reaffirm this opinion if such conditions change.

In rendering this opinion, ABN AMRO has not provided legal, regulatory, tax, accounting or actuarial advice and accordingly ABN AMRO does not assume any responsibility or liability in respect thereof. Furthermore, ABN AMRO has assumed that the Offer and the other transactions contemplated by the Combination Agreement will be consummated on the terms and conditions as set out in the Combination Agreement, without any changes to or waiver of their terms or conditions, in compliance with law and without the exercise of any appraisal rights, and that all requisite consents and approvals will be obtained. We have also assumed that debt financing for the cash portion of the Offer Consideration is available and we express no opinion on the price, terms or form of such financing.

The engagement of ABN AMRO, this letter and the opinion expressed herein are provided for the use of the Managing Board and Supervisory Board in connection with their evaluation of the Offer. This opinion does not in any way constitute a recommendation by ABN AMRO to any Shareholders as to whether such holders should accept or reject the Offer, vote in favour of or reject the Offer or otherwise act in relation to the Offer, or to the holders of NYSE Group Shares as to whether such holders should accept or reject the Merger, vote in favour of or reject the Merger or otherwise act in relation to the Merger.

ABN AMRO is acting as financial advisor to Euronext in connection with the Offer and will receive fees for its services, a significant portion of which fees are contingent upon consummation of the Offer. From time to time ABN AMRO and its affiliates may have also (i) maintained banking and financial advisory relationships with Euronext or NYSE Group, and (ii) executed transactions, for their own account or for the accounts of customers, in the Shares or the NYSE Group Shares or debt securities of Euronext or NYSE Group and, accordingly, may at any time hold a long or short position in such securities. ABN AMRO is a holder of Shares and NYSE Group Shares, and provides financing facilities to Euronext. We may in the future provide certain banking, financial advisory or financing services to, and execute transactions for our own account or for the accounts of our customers in the securities of, Euronext, the NYSE Group or NYSE Euronext.

It is understood that this letter may not in any form or manner be made public, disclosed, referenced to, nor relied upon by or otherwise used by, any third party for any purpose whatsoever, without the prior written consent of ABN AMRO. Notwithstanding the foregoing, this letter may be reproduced in full, and any public disclosure may also include references to this opinion and ABN AMRO and its relationship with Euronext (in each case in form and substance as ABN AMRO and its legal advisers shall approve), in any disclosure document relating to the Offer that is required to be filed with the US Securities and Exchange Commission and distributed to shareholders, so long as this letter is reproduced in full in such disclosure document and any description of or reference in such disclosure document to ABN AMRO, the opinion or the related analysis is in a form acceptable to us and our counsel.

This opinion is issued in the English language and reliance may only be placed on this opinion as issued in the English language. If any translations of this opinion are delivered they are provided only for

D-3

ease of reference, have no legal effect and ABN AMRO makes no representation as to (and accepts no liability in respect of) the accuracy of any such translation.

This letter and ABN AMRO's obligations to the Managing Board and the Supervisory Board hereunder shall be governed by and construed in accordance with Dutch law and any claims or disputes arising out of, or in connection with, this letter shall be subject to the exclusive jurisdiction of the Dutch Courts.

Based upon and subject to the foregoing, ABN AMRO is of the opinion that, as at the date hereof, the Offer Consideration is fair, from a financial point of view, to the Shareholders.

Yours sincerely,

ABN AMRO Corporate Finance France S.A.

SHAREHOLDER CIRCULAR OF EURONEXT N.V.		PROSPECTUS OF NYSE EURONEXT, INC.

To the Shareholders of Euronext N.V.:

Euronext and NYSE Group, Inc. have entered into an agreement providing for a combination of their businesses under a new holding company named NYSE Euronext. Euronext's business will be brought under the new holding company through an exchange offer, and NYSE Group's business will be brought under the new holding company through a merger (which, together with the exchange offer, is referred to as the "combination"). The combination will create the first global exchange company and the world's largest securities marketplace, encompassing seven exchanges in six countries.

In the exchange offer, Euronext shareholders will be offered the right to exchange each of their ordinary shares, par value €6 per share, of Euronext for €21.32 in cash and 0.98 of a share of common stock, par value $0.01 per share, of NYSE Euronext. Instead of receiving this standard offer consideration, Euronext shareholders will have an opportunity to make either a cash election to receive all cash for their Euronext shares, or a stock election to receive all stock for their Euronext shares. These elections, however, are subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of shares that would have been paid and issued if all tendering Euronext shareholders received the standard offer consideration.

Simultaneously with or a soon as possible after the completion of the merger, NYSE Euronext intends to effectuate a post-closing reorganization of Euronext and its subsidiaries that is intended to result in Euronext becoming a wholly owned subsidiary of NYSE Euronext. In the post-closing reorganization, Euronext shareholders who did not exchange such Euronext shares in the exchange offer will generally receive the same consideration that they would have received had they tendered their Euronext shares in the exchange offer and not made either the cash election or the stock election. In certain circumstances, payments made to Euronext shareholders in the post-closing reorganization may be subject to Dutch dividend withholding tax. See "The Combination—Material Dutch Tax Consequences—Dividend Withholding Tax." Although the structure of the post-closing reorganization may not be determined until the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer.

The combination agreement requires that the combination be approved by the NYSE Group stockholders and Euronext shareholders. To obtain these approvals, Euronext will hold an extraordinary meeting of its shareholders on [ • ], 2006, at which it will ask its shareholders to approve the combination agreement and the transactions contemplated thereby (and consider any other matters properly brought before the meeting). Information about the Euronext extraordinary meeting, the combination and other business to be considered by Euronext shareholders is contained in this document, which you are urged to read. In particular, see "Risk Factors" beginning on page [ • ].

Your vote is very important. Whether or not you plan to attend the Euronext extraordinary meeting, please take appropriate action to make sure your Euronext shares are represented at the extraordinary meeting. If you are a Euronext shareholder, blank votes and invalid votes will be regarded as votes not cast. The Euronext managing and supervisory boards have approved the combination agreement which provides that the boards will recommend, subject to fiduciary duties under applicable law, that the Euronext shareholders vote FOR the combination agreement and the transactions contemplated thereby.

Jean-François Théodore
Chief Executive Officer
Euronext N.V.

This document is dated [ • ], 2006, and is first being made available to the Euronext shareholders on or about [ • ], 2006.

The information contained herein is subject to completion or amendment. A registration statement relating to these securities has been filed with the U.S. Securities and Exchange Commission. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities, nor shall there be any sale of these securities, in any jurisdiction in which such offer, solicitation or sale is not permitted or would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

DRAFT SUBJECT TO COMPLETION, DATED [ • ], 2006

PROSPECTUS OF NYSE EURONEXT, INC.		OFFER TO EXCHANGE

Offer to Exchange
all shares, nominal value €6 per share, of Euronext

NYSE Group, Inc. and Euronext N.V. have entered into an agreement providing for a combination of their businesses under a new holding company named NYSE Euronext. Euronext's business will be brought under the new holding company through an exchange offer, and NYSE Group's business will be brought under the new holding company through a merger (which, together with the exchange offer, is sometimes referred to as the "combination"). The combination will create the first global exchange company and the world's largest securities marketplace, encompassing seven exchanges in six countries.

This document is being sent to U.S. holders of Euronext shares to effect the exchange offer. In this exchange offer, NYSE Euronext or a wholly owned subsidiary is offering, subject to the terms and conditions set forth herein, to acquire each share, par value €6 per share, of Euronext for €21.32 in cash, without interest, and 0.98 of a share of common stock, par value $0.01 per share, of NYSE Euronext. This exchange offer includes a mix and match election feature that allows holders of Euronext shares to elect to receive, in lieu of the mix of consideration described above: (a)[ • ] newly issued shares of NYSE Euronext common stock in exchange for each Euronext share tendered; or (b) €[ • ] in cash, without interest, in exchange for each share of Euronext tendered. The mix and match elections are subject to proration and allocation adjustments to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, will equal the total amount of cash and number of shares that would be paid and issued if all tendering Euronext shareholders received the standard offer consideration. You are not required to make any election or to make the same election for all of the Euronext shares you tender. See "The Combination Agreement—The Exchange Offer—Consideration to Euronext Shareholders".

The exchange offer will expire at [ • ], Paris time ([ • ], New York City time), on [ • ], unless it is extended or unless it is withdrawn prior to that time. You may withdraw any tendered Euronext shares at any time prior to the expiration time of the exchange offer.

If the exchange offer is consummated, a wholly owned subsidiary of NYSE Euronext will immediately merge with NYSE Group, so that both Euronext and NYSE Group will be subsidiaries of NYSE Euronext. In the merger, NYSE Group stockholders will have the right to receive one share of NYSE Euronext common stock for each of their shares of NYSE Group common stock.

Following the successful completion of the exchange offer and simultaneously with or as soon as possible after the merger, NYSE Euronext intends to effectuate a corporate reorganization of Euronext and its subsidiaries which will result in Euronext becoming a wholly owned subsidiary of NYSE Euronext, and to which we sometimes refer as the "post-closing reorganization". Under the post-closing reorganization, Euronext shareholders who did not tender their Euronext shares in the exchange offer will be generally provided with the same consideration that such shareholders would have received had such shareholders tendered their Euronext shares in the exchange offer and made no election. Although the structure of the post-closing reorganization may not be determined until the expiration of the exchange offer, in the event that less than 95% of the outstanding Euronext shares are acquired in the exchange offer, it is currently anticipated that a significant portion of the consideration paid to Euronext shareholders pursuant to the post-closing reorganization will be subject to Dutch dividend withholding tax. Application of the Dutch dividend withholding tax could cause the net value of the consideration received by Euronext shareholders in the post-closing reorganization to be substantially less than the net value of the consideration such shareholders would have received had they tendered their Euronext shares in the exchange offer. See "The Combination—Material Dutch Tax Consequences—Post Closing Reorganization Effectuated Other than Pursuant to the Compulsory Acquisition Procedure—Dividend Withholding Tax." The effect of the post-closing reorganization will be to eliminate any minority stockholder interest in Euronext after the completion of the exchange offer. For a description of these arrangements, see "The Combination Agreement—Post-Closing Reorganization."

Based on the current number of outstanding shares of NYSE Group common stock and Euronext shares, NYSE Euronext will issue approximately 269.7 million shares of NYSE Euronext common stock in the aggregate in the combination. NYSE Euronext has applied to list the NYSE Euronext common stock on the New York Stock Exchange (or the "NYSE") under the symbol "[ • ]," and on Euronext Paris (Eurolist by Euronext) under the symbol "[ • ]" (ISIN Code "[ • ]"). NYSE Group common stock, which is listed on the NYSE under the symbol "NYX," will be delisted after the merger is completed. In addition, NYSE Euronext intends to request the delisting of Euronext shares, which are listed on Euronext Paris (Eurolist by Euronext) under the symbol "NXT," (ISIN Code NL0000290641) as soon as permissible after the exchange offer or, if so applicable, the post-closing reorganization is completed.

Completion of the combination requires that at least two-thirds of the outstanding Euronext shares be tendered in the exchange offer. Subject to applicable law and regulations and the terms of the combination agreement, NYSE Euronext reserves the right, after consultation with Euronext, to modify or waive this condition and may reduce the minimum tender requirement to not less than a simple majority of Euronext shares and voting power. Information about the exchange offer, the combination and other business to be considered by Euronext shareholders is contained in this document, which we urge you to read. In particular, see "Risk Factors" beginning on page 34.

The terms and conditions of the exchange offer and the French tender offer prospectus (note d'information) have been approved by the French Autorité des marchés financiers, or "AMF" on [ • ]. However, this prospectus has not been approved by the AMF. This prospectus may not be used to make offers or sales to French or other non-U.S. holders of Euronext shares.

The table also presents the implied equivalent value of each Euronext share based on the standard offer consideration of €21.32 in cash and 0.98 of a share of NYSE Euronext common stock for each Euronext share. For purposes of calculating the implied value of a Euronext share as of any particular date, each share of NYSE Euronext common stock was assumed to have a value equal to the closing market price per share of NYSE Group common stock on such date, as reported on the NYSE, and such value was converted into euros at a rate of €1.00 = 1.2888, which was the Federal Reserve Bank of New York noon buying rate on May 31, 2006, or at a rate of €1.00 = $[ • ], which was the Federal Reserve Bank of New York noon buying rate on [ • ], 2006, as applicable.

You are urged to obtain current market quotations for shares of NYSE Group common stock and Euronext shares before making your decision with respect to the approval and adoption of the combination agreement. NYSE Group's common stock is listed on the New York Stock Exchange under the symbol "NYX". Euronext shares are listed on Euronext Paris (Eurolist by Euronext) under the symbol "NXT."

The following table presents, as of the same dates as the preceding table, the implied equivalent value of each Euronext share, under the three mix and match elections. As in the preceding table, for purposes of calculating the implied value of a Euronext share as of any particular date, each share of NYSE Euronext common stock was assumed to have a value equal to the closing market price per share of NYSE Group common stock on such date, as reported on the NYSE, and such value was converted into euros at a rate of €1.00 = 1.2888, which was the Federal Reserve Bank of New York noon buying rate on May 31, 2006, €1.00 = $1.2833, or at a rate of €1.00 = $[ • ], which was the Federal Reserve Bank of New York noon buying rate on [ • ], 2006 as applicable. The implied equivalent value of the standard offer consideration was calculated in the same manner as in the preceding table. The implied equivalent value of

an Euronext share exchanged pursuant to a valid all stock election was calculated by multiplying the closing market price per share of NYSE Group common stock on the NYSE by [ • ], the applicable exchange ratio for each Euronext share under the all stock election, and by Federal Reserve Bank of New York noon buying rate on the applicable day. The implied equivalent value of an Euronext share exchanged pursuant to a valid all cash election is fixed at [ • ].

The Exchange Offer

Consideration Offered to Euronext Shareholders

The combination agreement provides that Euronext will become a subsidiary of NYSE Euronext through an exchange offer. Pursuant to the combination agreement, NYSE Euronext or a wholly owned subsidiary is hereby offering to acquire, subject to the terms and conditions set forth herein, each outstanding Euronext share for €21.32 in cash (without interest) and 0.98 of a share of NYSE Euronext common stock. The foregoing mix of consideration is referred to as the "standard offer consideration." Assuming that each share of NYSE Euronext common stock has a value equal to one share of NYSE Group common stock, based on the closing price of $[ • ] of NYSE Group common stock and the euro-dollar noon buying rate of Federal Reserve Bank of New York on [ • ], 2006, the terms of the exchange offer value each Euronext share at €[ • ]. The combination agreement contains no provision that permits either party to terminate the combination agreement, or that alters the exchange ratio, because the stock price of NYSE Group common stock or Euronext shares has fallen below any agreed-upon minimum price or has risen above an agreed-upon maximum price. See "Risk Factors."

Mix and Match Election

The exchange offer contains a "mix and match" election to permit Euronext shareholders to receive more cash or more stock for their tendered Euronext shares, to the extent that either is available. Specifically, instead of receiving the standard offer consideration for their Euronext shares, Euronext shareholders will have an opportunity to make either:

•: a cash election to receive €[ • ] for each of their Euronext shares (the "Cash Consideration" with all Euronext shares for which this election is made being referred to herein as "Cash Election Shares"), or
•: a stock election to receive [ • ] shares of NYSE Euronext common stock for each Euronext share (the "Stock Consideration" with all Euronext shares for which this election is being referred to herein as "Stock Election Shares").

The cash election and stock election, however, are subject to proration to ensure that the total amount of cash paid, and the total number of shares of NYSE Euronext common stock issued, in the exchange offer to the Euronext shareholders, as a whole, are equal to the total amount of cash and number of NYSE Euronext shares that would have been paid and issued if all tendering Euronext shareholders received the standard offer consideration. A cash election will be satisfied in full only to the extent that off-setting stock elections have been made by other tendering holders of Euronext shares in the exchange offer.

Accordingly, there can be no assurance that Euronext shareholders will receive all of their consideration in the form that they have elected.

If the ratio of the total number of Cash Election Shares tendered in the exchange offer to the total number of Stock Election Shares tendered in the exchange offer, is not equal to [ ] ([ • ], the percentage of shares divided by [ • ], the percentage of cash, the "Ratio"), then the following pro-ration and allocation adjustment will be applied to the Cash Election Shares or the Stock Election Shares, as the case may be, tendered in the exchange offer:

•: In the event that the total number of Cash Election Shares tendered in the exchange offer, divided by the total number of Stock Election Shares tendered in the exchange offer, exceeds the Ratio, then each tendered Stock Election Share will receive the Stock Consideration, while the number of tendered Cash Election Shares will be reduced to the number required to achieve the Ratio. This reduction will be effected proportionately among the holders of all Cash Election Shares tendered in the exchange offer. The adjusted number of Cash Election Shares will be rounded down to the nearest whole number. All tendered Euronext shares deemed not to be Cash Election Shares as a result of this proration and allocation procedure will receive the standard offer consideration.
•: In the event that the total number of Cash Election Shares tendered in the exchange offer, divided by the total number of Stock Election Shares tendered in the European exchange offer is less than the Ratio, then each tendered Cash Election Share will receive the Cash Consideration, while the number of tendered Stock Election Shares will be reduced to the number required to achieve the Ratio. This reduction will be effected proportionately among the holders of all Stock Election Shares tendered in the exchange offer. The adjusted number of Stock Election Shares will be rounded down to the nearest whole number. All tendered Euronext shares deemed not to be Stock Election Shares as a result of this pro-ration and allocation procedure will receive the standard offer consideration.

Tendering Euronext shareholders who make no election will receive the standard offer consideration for their tendered Euronext shares.

Expiration Date of the Exchange Offer

The exchange offer will expire at [ • ] p.m., Paris time ([ • ] a.m. New York City time), on [ • ] unless (i) the AMF extends or suspends the period of the exchange offer; or (ii) the exchange offer is withdrawn prior to that time in accordance with the GRAMF.

The AMF has the sole authority to determine whether or not to extend the exchange offer period. NYSE Euronext may not itself extend the exchange offer period. The AMF may extend the exchange offer period under certain circumstances, including in the event of the initiation of a competing offer or of an improved offer by a competing bidder. The exchange offer period may also be extended or suspended in case a claim challenging the validity of the AMF's decision to approve the exchange offer and the exchange offer documentation is validly filed with a court of competent jurisdiction. If the offer period is extended or suspended by the AMF, NYSE Euronext will issue a press release announcing the AMF's decision and the new expiration date and time of the extended exchange offer.

Withdrawal Rights

A Euronext shareholder will have the right to withdraw any of its Euronext shares tendered pursuant to the exchange offer at any time prior to the expiration of the exchange offer. During the subsequent offering period (described below), a Euronext shareholder may withdraw any Euronext shares tendered during that subsequent period at any time prior to the expiration of the subsequent offering period. No consideration will be paid to the Euronext shareholder in respect of any withdrawn Euronext share.

For a withdrawal to be effective, the financial intermediary, the U.S. custodian or Netherlands Management Company B.V., in its capacity as Euronext's registrar, as applicable, must receive in a timely manner the written or facsimile transmission notice of withdrawal.

Acceptance and Return of Euronext Shares

If the exchange offer is successful (see "Conditions to Completing the Exchange Offer" below), NYSE Euronext will be deemed to have accepted for exchange all Euronext shares validly tendered and not properly withdrawn on or prior to the expiration of the offer period, as set forth in the final results of the exchange offer (avis de résultat définitif) published in France by the AMF.

In the event that any Euronext shares tendered in accordance with the instructions set forth in the exchange offer materials are not accepted for exchange pursuant to the terms and conditions of the exchange offer, these Euronext shares should be returned within two French trading days following the announcement of the lapse or withdrawal of the exchange offer.

Publication of Results

NYSE Euronext expects the AMF to publish the definitive results of the exchange offer not later than nine French trading days following the expiration date of the exchange offer period. However, since the completion of the exchange offer is conditioned on obtaining a minimum amount of tendered shares, NYSE Euronext expects the AMF to publish provisional results prior to its publication of the definitive results. The AMF's publication of the definitive results of the exchange offer will disclose the total number of Euronext shares and the corresponding percentage of total capital and voting rights of Euronext that have been validly tendered.

If the minimum tender condition is satisfied, the exchange offer will be automatically re-opened by the AMF within 10 French trading days following the publication of the definitive results. In this case, the exchange offer will be re-opened for a period of at least 10 French trading days.

NYSE Euronext will accept any and all Euronext shares tendered during the subsequent offering period and not validly withdrawn prior to the expiration of the subsequent offering period. Delivery of the NYSE Euronext common stock and, when applicable, the cash to be paid to tendering holders of Euronext shares in exchange for the Euronext shares tendered in the subsequent offering period will occur following the expiration of the subsequent offering period. In any subsequent offer period, the standard offer consideration will be the same as in the initial offer period. Euronext shareholders will be entitled to make

a mix and match election when tendering Euronext shares in the subsequent offering period, which will also be subject to proration so that the total number of shares of NYSE Euronext issued and total amount of cash paid is equal to the amounts that would have been payable if all Euronext shareholders tendering in the subsequent offering period had made the standard offer election and NYSE Euronext or its subsidiary will offer the same consideration that was offered during the initial offering period. For the avoidance of doubt, any prorating in the subsequent offer period will apply only to the pool of Euronext shares tendered during such subsequent offering period.

Procedures for Tendering Euronext Shares

Euronext shares can be held in three ways:

•: in an account with a U.S. custodian such as a broker, bank or trust company, through Euroclear France (in which case, the shares are registered in Euronext's shareholders' register in the name of Euroclear France);
•: in an account with a financial intermediary (other than a U.S. custodian), through Euroclear France (in which case, the shares are registered in Euronext's shareholders' register in the name of Euroclear France); or
•: as shares registered in Euronext's shareholders' register under the name of the shareholder.

Once the exchange offer has commenced, Euronext shareholders may tender their Euronext shares in the following ways:

•: Euronext shares held in an account with a U.S. custodian through Euroclear France. If a Euronext shareholder holds Euronext shares in an account with a U.S. custodian (such as a broker, bank or trust company) through Euroclear France, the U.S. custodian should either forward the transmittal materials and instructions obtained from a financial intermediary that is a Euroclear Affiliate or send a separate form prepared by the U.S. custodian. If any such Euronext shareholder has not yet received instructions from his U.S. custodian, the Euronext shareholder should contact his U.S. custodian directly.
•: Euronext shares held in an account with a financial intermediary, other than U.S. custodian, through Euroclear France. If a Euronext shareholder holds Euronext shares in an account with a financial intermediary other than a U.S. custodian, transmittal materials and instructions for participating in the exchange offer may be obtained through such financial intermediary before the last day of the exchange offer. Any such Euronext shareholder should contact his financial intermediary directly in order to obtain such transmittal materials and instructions.
•: Euronext shares registered in Euronext's shareholders register under the name of the shareholder. If a Euronext shareholder holds Euronext shares registered in Euronext's shareholders' register under the name of such shareholder, Netherlands Management Company B.V., in its capacity as Euronext's registrar, will send the transmittal materials and instructions for tendering shares in the exchange offer to such shareholder. If any such shareholder does not receive instructions, the Euronext shareholder should contact Netherlands Management Company B.V. directly.

You cannot tender Euronext shares in the exchange offer until the exchange offer has commenced.

Effects of Tender

By tendering Euronext shares, the tendering Euronext shareholder represents and warrants that the shareholder has the power and authority to tender, exchange, assign and transfer the Euronext shares

tendered and to acquire the NYSE Euronext common shares and/or cash issuable or payable upon the exchange of the tendered Euronext shares, and that, when and if the Euronext shares are accepted for exchange, NYSE Euronext or a wholly owned subsidiary will acquire good, marketable and unencumbered title to the tendered Euronext shares, free and clear of all liens, restrictions, charges and encumbrances, and not subject to any adverse claim or right. NYSE Euronext reserves the right to reject any Euronext shares that it determines do not satisfy these conditions.

Delivery of Offer Consideration; Settlement Date

In the event that the exchange offer is successful, NYSE Euronext common shares and cash will be delivered to the tendering holders of Euronext shares following the publication by the AMF of the final results of the exchange offer for Euronext shares. If the exchange offer is so consummated, the final settlement date for the exchange offer is currently expected to be within approximately 12 to 18 French trading days following the expiration date of the exchange offer. Similarly, in the event of a subsequent offering period, if any, settlement is expected to occur within 12 to 18 French trading days following the expiration of that subsequent offer period. Any cash paid to tendering Euronext shareholders will be in euros.

Under no circumstances will interest be paid on the exchange of Euronext shares for NYSE Euronext common shares and/or cash, regardless of any delay in making the exchange.

Consequences of a withdrawal or a lapse of the exchange offer

If the minimum tender condition is not satisfied the exchange offer will lapse upon publication of the definitive results.

The exchange offer may also lapse if the AMF's decision to approve the exchange offer and the exchange offer documentation is declared null and void by a competent French court.

If the exchange offer lapses or if NYSE Euronext withdraws the exchange offer in accordance with the provisions of the combination agreement and the GRAMF, the Euronext shares that a Euronext shareholder tendered in the exchange offer will be returned to the shareholder without interest or any other payment being due. This should occur within two French trading days following the publication of the definitive results or such withdrawal, as applicable.

No Fractional Shares

No fractional NYSE Euronext ordinary shares will be issued in connection with the exchange offer. In lieu of any fraction of a NYSE Euronext ordinary share that a Euronext shareholder would otherwise have been entitled to receive pursuant to the terms of the exchange offer, such Euronext shareholder will receive an amount in cash (rounded up to the nearest whole euro cent) equal to the product of that fraction and the average sale price per NYSE Euronext ordinary share, net of expenses, realized on Euronext Paris (Eurolist by Euronext) in the sale of all the aggregated fractional NYSE Euronext ordinary shares (the total number of such shares being rounded up to the nearest whole number that would have otherwise been issued in the exchange offer).

In no event will interest be paid on the cash to be received in lieu of any fraction of a NYSE Euronext ordinary share, regardless of any delay in making the payment.

Fees and Expenses

Except as set forth below, NYSE Euronext will not pay any fees or commissions to any broker or other person soliciting tenders of Euronext shares pursuant to the exchange offer.

[DEALER-MANAGERS] are acting as joint dealer-managers in the United States in connection with the exchange offer [and [FRENCH PRESENTING BANKS] will act as presenting banks ("banques présentatrices") in France in connection with the exchange offer], and they or certain of their affiliates have provided financial advisory services to NYSE Euronext in connection with the contemplated combination with Euronext.

[DEALER-MANAGERS] and [FRENCH PRESENTING BANKS]] will not receive any specific fee as dealer-managers. NYSE Euronext also will reimburse the financial advisors and dealer-managers for their expenses and indemnify them against specified liabilities and expenses in connection with the exchange offer, including liabilities under the U.S. federal securities laws.

The information agent may contact holders of Euronext shares by mail, telephone, telex, fax, e-mail and personal interview and may request brokers, dealers and other nominee shareholders to forward these exchange offer materials to owners of Euronext shares. The information agent will receive reasonable and customary fees for these services, plus reimbursement of its out-of-pocket expenses. NYSE Euronext will indemnify the information agent against specified liabilities and expenses in connection with the exchange offer, including liabilities under the U.S. federal securities laws and the European securities laws. Indemnification for liabilities under the U.S. federal securities laws or the European securities laws may be unenforceable as against public policy.

NYSE Euronext has retained [ • ] to act as exchange agent in connection with the exchange offer.

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Pursuant to the Delaware General Corporation Law, a corporation may indemnify any person in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than a derivative action by or in the right of such corporation) who is or was a director, officer, employee or agent of such corporation, or serving at the request of such corporation in such capacity for another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of such corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

The Delaware General Corporation Law also permits indemnification by a corporation under similar circumstances for expenses (including attorneys' fees) actually and reasonably incurred by such persons in connection with the defense or settlement of a derivative action or suit, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to such corporation unless the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

To the extent a director, officer, employee or agent is successful in the defense of such an action, suit or proceeding, the corporation is required by the Delaware General Corporation Law to indemnify such person for actual and reasonable expenses incurred thereby. Expenses (including attorneys' fees) incurred by such persons in defending any action, suit or proceeding may be paid in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it is ultimately determined that such person is not entitled to be so indemnified.

The Delaware General Corporation Law provides that the indemnification described above shall not be deemed exclusive of other indemnification that may be granted by a corporation pursuant to its bylaws, disinterested directors' vote, stockholders' vote, and agreement or otherwise.

The Delaware General Corporation Law also provides corporations with the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation in a similar capacity for another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability as described above.

The current NYSE Euronext certificate of incorporation requires NYSE Euronext to indemnify and hold harmless any director, officer or employee of NYSE Euronext to the fullest extent permitted by the Delaware General Corporation Law against all expenses, liabilities and losses (including attorney's fees, judgments, fines, ERISA excise taxes or penalties and amounts to be paid in settlement) reasonably incurred or suffered by such person in connection with any action, suit or proceeding in which they were, are, or have been threatened to be involved by virtue of their service as a director, officer or employee of NYSE Euronext or their service at the request of NYSE Euronext as a director, officer, employee or agent of, or in any other capacity with respect to, another corporation or a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans. In general, NYSE Euronext will indemnify such a person who initiates an action, suit or proceeding only if that action, suit or proceeding was authorized by the NYSE Euronext board of directors.

II-1

In addition, under the current NYSE Euronext certificate of incorporation, NYSE Euronext is required to pay, in advance of the disposition of any action, suit or proceeding, any reasonable expenses incurred by such a director or officer subject (if required by the Delaware General Corporation Law) to such person agreeing to repay any such amounts if it is ultimately determined that such person is not entitled to be indemnified for such expenses.

Upon consummation of the transactions contemplated by the Combination Agreement (which is included as Exhibit 2.1 of this registration statement), NYSE Euronext will amend and restate its certificate of incorporation and bylaws.

The NYSE Euronext certificate of incorporation that will be in effect upon completion of the mergers will require NYSE Euronext to indemnify and hold harmless any director, officer or employee of NYSE Euronext to the fullest extent permitted by Delaware law, against all expenses, liabilities and losses, including attorney's fees, judgments, fines, ERISA excise taxes or penalties and amounts to be paid in settlement, reasonably incurred by those persons in connection with any action, suit or proceeding in which they were, are, or have been threatened to be involved by virtue of their service as a director or officer of NYSE Euronext or their service at the request of NYSE Euronext as a director, officer, employee or agent of, or in any other capacity with respect to, another corporation or a partnership, joint venture, trust or other entity or enterprise, including service with respect to employee benefit plans. In general, NYSE Euronext will indemnify such a director or officer who initiates an action, suit or proceeding only if such action, suit or proceeding was authorized by the NYSE Euronext board of directors.

In addition, under the NYSE Euronext certificate of incorporation that will be in effect upon completion of the mergers, NYSE Euronext will pay, in advance of the disposition of any action, suit or proceeding, any reasonable expenses incurred by such a director or officer subject (if required by the Delaware General Corporation Law) to such person agreeing to repay any such amounts if it is judicially determined that such person is not entitled to be indemnified for such expenses.

The foregoing statements are subject to the detailed provisions of Section145 of the Delaware General Corporation Law, the full text of the NYSE Euronext certificate of incorporation that will be in effect upon completion of the mergers, a form of which is filed as Exhibit 3.1 to this registration statement, and the full text of the NYSE Euronext bylaws that will be in effect upon completion of the mergers, a form of which is filed as Exhibit 3.2 to this registration statement.

ITEM 22. UNDERTAKINGS

(A) The undersigned registrant hereby undertakes as follows:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act");

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(B)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) The registrant undertakes that every prospectus (i)that is filed pursuant to paragraph (1)immediately preceding, or (ii)that purports to meet the requirements of Section10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(C) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the

II-8

matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(D) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into this registration statement pursuant to Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means; this includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request.

(E) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.
